SYMPTOM When printing with the PS driver, the Euro currency symbol is not printed out with 112 of 136 fonts, which are stored in the font ROM in GW-based products. The following are GW-based products: Model-K3, Model-K P2, Russian-C2, Adonis- C2, Model-A P3, Model-J P1b, Model-J CF Model-U P1, Model-U C1, Martini-C1.

CAUSE The Euro currency symbol was not included in the font ROM.

SOLUTION Temporary Solution (1) A workaround for each operating system has been previously released on the FAQ page, and is included on pp. 5-8 below. Temporary Solution (2) Although the font ROM will be modified as a permanent solution (details below), before this can be applied, the controller firmware has been modified on the following GW-based products:

Product Firmware Version Product Firmware Version Model-K3 1.01 (Controller) Model-J P1b 2.18 (Controller) Model-K P2 1.06.1 (Controller) Model-J CF 1.11 (Printer Application) Russian-C2 2.03 (Printer Application) Model-U P1 2.20 (Printer Application) Adonis-C2 3.09 (Printer Application) Model-U C1 1.22 (Printer Application) Model-A P3 1.08 (Controller) Martini-C1 1.01 (Printer Application)

Specifically, the Euro currency symbol has been added along with the PS fonts download feature, which allows the symbol to be downloaded to machine RAM. Enable this feature by changing the setting of Bit SW#3-0 to 1 (ON) in SP mode (default: OFF).


Remarks for Temporary Solution 2: 1. Switching PDL to PS takes approximate 7 to 10 seconds.

When PS fonts download is enabled, the Euro symbol is temporarily downloaded to the machine RAM at the first PS printing job, and whenever the PDL is switched from RPCS or PCL to PS. The total download time is approximately 7 to 10 seconds. This is because once the data is downloaded, it will remain in the RAM until the PDL is switched or the power turned off.

2. Printing high image area documents at 1200 dpi may cause a memory overflow error in machines equipped only with 32MB of memory (ex. Model-K P2). This is because the PS fonts download feature uses approximately 800kB, which can bring the amount of available memory close to capacity with the above printing conditions. Workaround: ! Printing at 600dpi may prevent an overflow, even with just the 32MB memory

installed. ! Changing the memory usage setting from Frame Priority to Font Priority may

prevent an overflow.

Permanent Solution Modification of the font ROM on the ROM DIMM or the Controller Board, from October 02, production or later (details differ depending on the model). Specifically, the Euro currency symbol has been added to the 112 fonts mentioned above. Note: 1. When the new ROM DIMM or Controller Board is installed, it is not necessary to

disable the PS fonts download feature (temporary solution). 2. An MB will be issued separately announcing the P/N change for the ROMM DIMM and

Controller Boards, and cut-in serial number. ROM DIMM and Controller Board P/N:

Font Table Euro symbol is printed correctly. This is a symbol font, so no countermeasure is applied.

Both temporary and permanent solutions work to print out the Euro currency symbol correctly.

Process control mode timing To reduce the cycle of process control mode (every 200 prints), Mono (Bk) prints are no longer counted for process control. Charge corona cleaning Charge corona cleaning mode-entering timing has been changed from 640 to 700. After 700 development counts (stops in the middle of the job), charge corona cleaning is carried out. SC560 (Zero cross error) If the following abnormal frequency for the power source is detected when the main switch is turned on, SC560 is displayed (upper limits eliminated, as they are unnecessary). Old control for SC560: 50Hz: 45>Detected Hz or 54Detected Hz or 64Detected Hz, 60Hz: 55>Detected Hz SP1-905-01 (pressure roller type): To prevent fusing jams (wrapping around the pressure roller), the layer thickness of the pressure roller has been changed from 1.5 mm to 2.1mm from the first production machines. When the old firmware from 1.192:01 or older version is updated to 1.202.01 or later for the first time, even if the new pressure roller is installed, it is necessary to select new in SP1-905-01 to initialize fusing temperature control. The settings for the August production machines have been input on the production line. When firmware 1.192:01 or older is updated to 1.202.01 or later for the first time , the machine cannot judge which data (old or new) should be used for fusing control. Note : When selecting 0 in SP1-905-1 and then pressing # on the LCD, the new control data is applied to fusing control. 0 : new pressure roller type (2.1mm), 1 : old pressure roller type (1.5mm) SP2-944-4 and 5 :(OPC Lubrication High Coverage) The default settings for SP2-944-4 and 5 have been reviewed and changed to reduce the cycle of OPC lubrication mode.

SP2-905-01: (Paper transfer roller type) To improve transfer, the shape of the paper transfer roller has been changed from the 1st production. Due to this modification, paper transfer currents (SP2-310-001 to SP2-341-032) and paper transfer adjustment (SP2-903-01) have been reviewed. The settings for August production machines have been input on the production line. This SP changes the default and factory settings for SP2-310-001 to SP2-341-032 and SP2-903-01 for both types. It is

necessary to set the type to 0 and press the # key when firmware version 1.181:01 or older (August production machines) is updated to 1.192:01 or newer for the first time. This is because the machine cannot judge which data (old or new) should be used for paper transfer currents. Check the SP settings after updating the firmware (SP2-310-001 to SP2-341-032, and SP2-903-01). Note: All settings will be initialized to their new defaults (see tables below), therefore any previously input field customized settings must be re-input manually. 0: New paper transfer roller type (Drum type), 1: Old paper transfer roller type (straight type) SP2-321-7 and 9: (Paper transfer bias of edge) The default settings have been changed from 1.0 to 0.8 to improve image quality in low temperature and low humidity conditions. SP7-931-001 to 017 (Engine status display) The engine log can be checked with SP mode for field symptom evaluation, because if the machine stalls, the SMC cannot be printed out. Checking the indication in this SP can be helpful in problem/cause identification. Reducing fan motor rotation period The development fan is stopped and the fusing unit fan turns at half speed for 15 seconds after the last sheet of paper exits the printer. With the previous firmware, the fusing unit fan and development fan were both run for 3 minutes after paper exit. Doctor roller reverse mode timing After 20 prints (at job end) or after 50 prints (stops in the middle of the job), the machine carries out the doctor roller reverse rotation to maintain good printing quality . A4/LT SEF or shorter printing is counted as 1 and a print longer than A4/LT SEF is counted as 2. With the prototype firmware, A4/LT LEF or shorter printing is counted as 1 and longer than A4/LT LEF is counted as 2. This is to reduce the frequency of the doctor roller reverse.

Other ( )

SYMPTOM Image skew when feeding from mainframe Trays 1 and 2.

Cause The operator does not set the side fence flush against the paper stack.

Field Action 1 Advise customers that the side fence should be set flush against the loaded paper stack, or in cases where the customer gives approval, secure the side fences in place with two screws. Note: The level of skew will increase twofold if there is a 1mm gap between the paper and side fence.

Field Action 2 As a supplement, the level of skew can be further minimized by increasing the paper buckle with SP1-003. Try adjusting this value several times while checking the level of skew on the printouts, keeping in mind that a higher value tends to cause Z-folds and a lower value tends to cause paper jams.


Field Action 3 The following sheets of Mylar have been added to the side fence from the September production. For the field machines, please refer to the procedure below.

Part number Quantity Description G0702735 2/Tray Guide Plate - Side Fence

Procedure 1. Clean the attachment surface on the

Front Side Fence (AF016097) with alcohol.

2. Attach the Mylar (G0702735) to the Front Side Fence as shown in the illustration.

The following field machines require the Mylar to be attached: August '02 production serial numbers are as follows.

Subject: GW Products - Hardware Ethernet Problem Prepared by: T. Itoh From: Technical Services Sec. Service Planning Dept. Classification: Troubleshooting




Other ( )

SYMPTOM When the main switch is turned on, the error message Hardware Ethernet Problem may be displayed under the following condition on the GW-based products. Conditions: Network speed on the hub has been set to 100Mbps fixed with full duplex, and Length of network cable is too long (60 m or more) or the cable quality is not good

enough

CAUSE When the main switch is turned on, the machine performs a loop-back test. If the cable length is too long or its quality is not good enough, the damping factor for the data transmission becomes worse, and the machine incorrectly detects an error during this test. This happens only when the network speed is set to 100Mbps fixed with full duplex. The PHY chip used on the controller board causes this.

SOLUTION - Temporary Solution - Set the network speed on the hub to Auto-sensing, Use a shorter cable or a cable with a lower damping factor, or Disconnect the network cable and power on the printer; then, set the cable after the

printer comes to the ready condition. - Permanent Solution - The controller firmware will be modified to avoid the incorrect detection of this error message. The schedule of firmware modification is as follows.

BICU(Engine)

Symptom Corrected VersionThe paper feed/transport timing for the duplex interleaf function (one sheet in duplex unit, one fed from tray) has been improved to ensure better paper transport.

1.213:01

SC546 & SC556 Detection conditions for SC546/556 have been changed so that they are triggered by a 50C/sec jump or drop in thermistor temperature data (old: 20C/sec). This is because these SCs were being reported from the field in Japan in environments below 5C (installation requirements: 10C minimum), i.e. unnecessary SC occurrences. Note: When the actual fusing temperature is below 5C, the temperature curve for thermistor data is unstable and nonlinear, triggering the SCs more easily.

1.212:01

Toner end and/or toner near end may be detected even when the toner cartridge still contains enough to continue printing.

1.204:1

Process control mode timing To reduce the cycle of process control mode (every 200 printings), Mono (Bk) prints are no longer counted for process control. Charge corona cleaning Charge corona cleaning mode-entering timing has been changed from 640 to 700. After 700 development counts (stops in the middle of the job), charge corona cleaning is carried out. SC560 (Zero cross error) If the following abnormal Hertz for the power source is detected when the main switch is turned on, SC560 is displayed (upper limits eliminated, as they are unnecessary). Old control for SC560: 50Hz: 45>Detected Hz or 54Detected Hz or 64Detected Hz, 60Hz: 55>Detected Hz SP1-905-01 (pressure roller type): To prevent fusing jams (wrapping around the pressure roller) the layer thickness of the pressure roller has been changed from 1.5 mm to 2.1mmfrom the first production machines. When the old firmware from 1.192:01 or older version is updated to 1.202.01 or later for the first time, even if the new pressure roller is installed, it is necessary to select new in SP1-905-01 to initialize fusing temperature control. The settings for the August production machines have been input on the production line. When firmware 1.192:01 or older is updated to 1.202.01 or later for the first time, the machine cannot judge which data (old or new) should be used for fusing controll. Note : When selecting 0 in SP1-905-1 and then pressing # on the LCD, the new control data is applied to fusing control. 0 : new pressure roller type (2.1mm), 1 : old pressure roller type (1.5mm)

1.202.01


SP2-944-4 and 5 :(OPC Lubrication High Coverage) The default settings for SP2-944-4 and 5 have been reviewed and changed to reduce the cycle of OPC lubrication mode. SP2-944-4 : Sheets-1 : [10 to 80/ 30 / 1sheet/step] SP2-944-5 : Sheets-2 : [10 to 80/ 60 / 1sheet/step] SP2-905-01: (Paper transfer roller type) To improve the transferability, the shape of the paper transfer roller has been changed from the 1st production. Due to this modification, paper transfer currents (SP2-310-001 to SP2-314-032) and paper transfer adjustment (SP2-903-01) have been reviewed. The settings for August production machines have been input on the production line. This SP changes the default and factory settings for SP2-310-001 to SP2-314-032 and SP2-903-01 for both types. It is necessary to set the type to 0 and press # key when firmware version 1.181:01 or older (August production machines) is updated to 1.192:01 or newer for the first time. This is because the machine cannot judge which data (old or new) should be used for paper transfer currents. Check the SP settings after updating the firmware (SP2-310-001 to SP2-314-032, and SP2-903-01). Note: All settings will be initialized to their new defaults (see tables below), therefore any previously input field customized settings must be re-input manually. 0: New paper transfer roller type (Drum type), 1: Old paper transfer roller type (straight type) SP2-321-7 and 9: (Paper transfer bias of edge) The default settings have been changed from 1.0 to 0.8 to improve image quality in low temperature and low humidity conditions. SP7-931-001 to 017 (Engine status display) Engine log can be checked by SP mode for field symptom evaluation, as if the machine stalls, the SMC cannot be printed out. Checking the indication in this SP can be helpful in problem/cause identification. Reducing fan motor rotation period The development fan is stopped and the fusing unit fan is rotated at half speed for 15 seconds after the last sheet of paper exits the printer. With the previous firmware, the fusing unit fan and development fan were both run for 3 minutes after paper exit.

1.192:01

Doctor roller reverse mode timing After 20 prints, at job end or after 50 prints (stops in the middle of the job), the machine carries out the doctor roller reverse rotation to maintain good printing quality. A4/LT SEF or shorter printing is counted as 1 and the printing longer than A4/LT SEF is counted as 2. With the prototype firmware, A4/LT LEF or shorter printing is counted as 1 and longer than A4/LT LEF is counted as 2. This is to reduce the frequency of the doctor roller reverse mode.

Other (Specification change)

Please note the following change in counter specification. Although a production line modification will not be applied to some products, the action described in 4. Important Notes for Installation below must be taken for all products at installation.

Overview: Electronic counters will now be set to 0 when released from the factory, instead of being set to a negative value.

Background: Previously, counters were set to a negative value when shipped from the factory, and later set to 0 at installation, following installation test copies/prints. However this may cause confusion among some customers as to why the counter value at the commencement of the contract is 0, even though some installation test copies have already been made.

Details:

1. Specification Change Specification Current The initial value of the electrical counter is negative when products

are shipped from the factory.

Note: After making test samples at installation, the negative counter value can be set to 0 with SP mode.

New The initial value of the electrical counter is 0 when products are shipped from the factory.

Note: After making test samples at installation, the (positive) counter value cannot be set back to 0 with SP mode.


2. Firmware Modification Due to the counter modification, SP5-849 has also been changed as follows for products that have this SP mode (listed below).

SP mode name: Specification: Current Counter Clear

Day When the electrical counter is changed from a

negative value to 0, the machine recognizes this as the counter clear day and stores this date in the NVRAM.

New Installation Date When the electrical counter reaches a value of 20, the machine recognizes this as the installation date and stores this date in the NVRAM.

NOTE: The following products have SP5-849. The new firmware for these products has

not yet been released. However, the release notes for each will clearly mention the new firmware version. New products: Bellini-C2, Adonis C3 Current products: Martini C1, Model-U C1

3. Schedule for the Counter Modification The following is the current schedule for when the counter modification will be applied. Please note that there are some models to which the change will not be applied (marked as ---), due to production schedules, production lot quantities, and sales figures. NOTE: The actual cut-in months that have been confirmed appear in the Cut-in

production month column below. This RTB will be reissued when these dates have been confirmed for the remaining products.

NOTE: The counter change will be applied as a running change to production units only.

For machines already shipped out or in the field, please be sure to take the action described below in Section 4.

4. Important Notes for Machine Installation All Products Please be sure to perform the following at machine installation: 1. If the product is from before the counter modification, i.e. the counter is at a negative

value, be sure to set the counter to 0 first, then make the installation test samples. Digital products Set the electrical counter to 0 with SP mode. Analog products Set the mechanical counter to 0 with a reset key (tool).

2. If the product is modified, i.e. the counter is already at 0 (or above 0 following pre-

installation at a service depot), simply make the installation test samples. 3. After completing the installation, make sure to record the counter value. This is very

important, as this value will be used for billing with Meter Click contracts. Also, inform the customer of the value along with the reason why the counter does not start from 0.

BICU(Engine)

Symptom Corrected Version In color mode (2C or more) with LT LEF and duplex, SC280 is mis-detected if 5 or more originals are scanned during machine warm-up. The machine may freeze up when returning to stand-by mode from panel-off or low power mode under the following: LEF job !!!! SEF job !!!! Enters panel-off/low-power within 3 minutes !!!! Next job initiated, enters stand-by mode. SC670 is sometimes misdetected when the SMC report is printed.

1.242.01

The detection conditions for SC412 (2nd transfer disconnection) have been changed from 60ms to 240ms to prevent misdetections that can sometimes occur in low-temperature conditions. This is because this SC was being reported from the field in Japan in environments below 5C (installation requirements: 10C minimum), i.e. unnecessary SC occurrences. Note: When the temperature is below 5C, the high voltage supply board does not supply the target transfer roller current due to the high resistances of the image transfer belt and paper transfer roller, triggering the SC more easily. SP2-801-03 (Additional Value of the charge corona cleaning interval) has been newly added. The cleaning interval for the additional charge corona unit has been adjusted as shown. [0 ~ 5000 / 100 / 100 counts/step] With this new SP, it is possible to adjust the interval for charge corona cleaning in the middle of a job: Old:

The charge corona cleaning is carried out after 600 development counts (SP2-801-1), at job end or after 700 development counts (no adjustment) in the middle of the job.

After The charge corona cleaning is carried out after 600 development counts (SP2-801-1), at job end or after 700 development counts (= the sum of the settings in SP2-801-1 and -3) in the middle of the job.

SC571 Software changed so that oil end detection is not counted for supplying oil from the oil tank to the oil reservoir in the oil supply unit while the fusing unit is not working (i.e. SCs and jams). This is to avoid oil overflow conditions that can be caused by winter humidity (humidification).

1.233:01


Symptom Corrected Version Text mode in mono color mode Text Mode in mono color mode also uses the separation filter, which may sometimes cause separation errors. The separation filter has been reviewed. The machine may freeze when a paper jam occurs or when the main switch is turned on (found in laboratory tests). SC120 was displayed instead of SC122 when the scanner home position was initialized. The paper feed/transport timing for the duplex interleaf function (one sheet in duplex unit, one fed from tray) has been improved to ensure better paper transport.

1.213:01

SC546 & SC556 Detection conditions for SC546/556 have been changed so that they are triggered by a 50C/sec jump or drop in thermistor temperature data (old: 20C/sec). This is because these SCs were being reported from the field in Japan in environments below 5C (installation requirements: 10C minimum), i.e. unnecessary SC occurrences. Note: When the actual fusing temperature is below 5C, the temperature curve for thermistor data is unstable and nonlinear, triggering the SCs more easily.

1.212:01

Toner end and/or toner near end may be detected even when the toner cartridge still contains enough to continue printing.

1.204:1

Process control mode timing To reduce the cycle of process control mode (every 200 printings), Mono (Bk) prints are no longer counted for process control. Charge corona cleaning Charge corona cleaning mode-entering timing has been changed from 640 to 700. After 700 development counts (stops in the middle of the job), charge corona cleaning is carried out. SC560 (Zero cross error) If the following abnormal Hertz for the power source is detected when the main switch is turned on, SC560 is displayed (upper limits eliminated, as they are unnecessary). Old control for SC560: 50Hz: 45>Detected Hz or 54Detected Hz or 64Detected Hz, 60Hz: 55>Detected Hz SP1-905-01 (pressure roller type): To prevent fusing jams (wrapping around the pressure roller) the layer thickness of the pressure roller has been changed from 1.5 mm to 2.1mm from the first production machines. When the old firmware from 1.192:01 or older version is updated to 1.202.01 or later for the first time, even if the new pressure roller is installed, it is necessary to select new in

1.202.01


Symptom Corrected Version SP1-905-01 to initialize fusing temperature control. The settings for the August production machines have been input on the production line. When firmware 1.192:01 or older is updated to 1.202.01 or later for the first time, the machine cannot judge which data (old or new) should be used for fusing controll. Note : When selecting 0 in SP1-905-1 and then pressing # on the LCD, the new control data is applied to fusing control. 0 : new pressure roller type (2.1mm), 1 : old pressure roller type (1.5mm) SP2-944-4 and 5 :(OPC Lubrication High Coverage) The default settings for SP2-944-4 and 5 have been reviewed and changed to reduce the cycle of OPC lubrication mode. SP2-944-4 : Sheets-1 : [10 to 80/ 30 / 1sheet/step] SP2-944-5 : Sheets-2 : [10 to 80/ 60 / 1sheet/step] SP2-905-01: (Paper transfer roller type) To improve the transferability, the shape of the paper transfer roller has been changed from the 1st production. Due to this modification, paper transfer currents (SP2-310-001 to SP2-314-032) and paper transfer adjustment (SP2-903-01) have been reviewed. The settings for August production machines have been input on the production line. This SP changes the default and factory settings for SP2-310-001 to SP2-314-032 and SP2-903-01 for both types. It is necessary to set the type to 0 and press # key when firmware version 1.181:01 or older (August production machines) is updated to 1.192:01 or newer for the first time. This is because the machine cannot judge which data (old or new) should be used for paper transfer currents. Check the SP settings after updating the firmware (SP2-310-001 to SP2-314-032, and SP2-903-01). Note: All settings will be initialized to their new defaults (see tables below), therefore any previously input field customized settings must be re-input manually. 0: New paper transfer roller type (Drum type), 1: Old paper transfer roller type (straight type) SP2-321-7 and 9: (Paper transfer bias of edge) The default settings have been changed from 1.0 to 0.8 to improve image quality in low temperature and low humidity conditions. SP7-931-001 to 017 (Engine status display) Engine log can be checked by SP mode for field symptom evaluation, as if the machine stalls, the SMC cannot be printed out. Checking the indication in this SP can be helpful in problem/cause identification. Reducing fan motor rotation period The development fan is stopped and the fusing unit fan is rotated at half speed for 15 seconds after the last sheet of paper exits the printer. With the previous firmware, the fusing unit fan and development fan were both run for 3 minutes after paper exit.

Symptom Corrected Version Doctor roller reverse mode timing After 20 prints, at job end or after 50 prints (stops in the middle of the job), the machine carries out the doctor roller reverse rotation to maintain good printing quality. A4/LT SEF or shorter printing is counted as 1 and the printing longer than A4/LT SEF is counted as 2. With the prototype firmware, A4/LT LEF or shorter printing is counted as 1 and longer than A4/LT LEF is counted as 2. This is to reduce the frequency of the doctor roller reverse mode.
