bloodshot eyes or mild inflammation. ✓ If fluid enters your mouth, consult a physician immediately. ✓ If fluid is swallowed, do not force the person to vomit, and consult with a physician immediately. If the

person is forced to vomit, fluid may get caught in the trachea, which can be dangerous.

2. NOTES ON USAGE AND STORAGE.

When using the printer.

✓ Keep the printer running in a stable and controlled environment under these temperature and humidity values: 20°C ~ 25°C (68°F ~ 41°F) and 45% ~ 65% of relative humidity.

✓ Be sure the operating conditions suit the media. For more information, see the documentation supplied with the media.

✓ Also, when operating in dry areas, air-conditioned environment, or under direct sunlight, maintain the appropriate humidity.

✓ Do not bend or tug the waste ink tube. Ink could spill inside or around the printer. ✓ Avoid using the printer in locations with heat sources or locations that are exposed to direct drafts from

ventilators or air conditioners. The print head nozzles could dry out and clog. ✓ When the power is on, do not remove the power plug or cut the power at the breaker. The carriage may

not be capped properly. In this case, turn on the power and wait until capping is performed automatically.

✓ Be sure that the waste ink bottle is installed whenever the printer is on.





FOR THE USER




When not using the printer.

✓ If you do not print for a long time, the print head nozzles may become clogged. Turn the printer on at least once a week to prevent the print head clogging.

✓ Leaving the printer for too long without turning it on may result in a malfunction. Repair work for such malfunction will be charged.

✓ If you will not be using the printer for more than 2 weeks, maintenance must be performed by a service engineer before and after this period. This maintenance work will be charged.

✓ Note that even if proper maintenance has been done before a long period of non-use, repair may be necessary when doing maintenance for reusing the printer, depending on the period and conditions of storage. In such a case, the repair work will also be charged. Contact your local dealer or [email protected] for more information.

✓ The media may also become wavy or curled, causing jams or resulting in the media coming into contact with the print head. Remove the media before storing the printer.

✓ Store the printer after confirming that the print head has been capped. If the print head is left uncapped for a long time, the print quality may decline.

✓ Close all covers before placing the printer in storage. If you are not using the printer for a long time, put the gray anti-static cover (provided with the printer) on the printer to prevent dust build-up. The print head nozzles are very small, and they can become clogged easily if fine dust gets on the print head, and you may not be able to print properly.

✓ If you have not used the printer for a long time, check the print head for clogging before you start printing. Perform head cleaning if the print head is clogged.

✓ When storing the printer, be sure that it is level: do not store it on an angle, on end, or upside down.

When handling the ink bottles.

✓ Store the ink bottles at room temperature out of direct sunlight. ✓ To ensure print quality, use all the ink in the ink bottle before the expiry date. (One year after the

manufacture date). ✓ If the ink bottle has been stored in a cold location for a long period of time, keep at room temperature

for at least 24 hours before using. ✓ Be sure not to leave any ink in the ink bottle after refilling the Big Ink System. ✓ Refill the Big Ink System as soon as possible after opening the ink bottle.

When handling the media before printing.

✓ Do not fold the media or damage the printable surface.

✓ Do not touch the printable surface. Moisture and oils from your hands can affect print quality.

✓ When handling media, hold it by both edges. We recommend wearing cotton gloves. ✓ Keep the media dry. ✓ Packaging materials can be used to store media and should not be thrown away. ✓ Avoid locations that are subject to direct sunlight, excessive heat, or humidity. ✓ When not in use, media should be removed from the printer, rewound, and inserted in its original

packaging for storage. Leaving media in the printer for extended periods may cause it to deteriorate.

When handling the media just after being printed.

✓ Do not rub or scratch the printed surface. If it is rubbed or scratched, the ink may peel off. ✓ Do not touch the printed surface, as this may remove the ink. ✓ Make sure printouts are completely dry before folding or stacking, as otherwise discoloration or other

marks may appear where the prints touch. These marks will disappear if the prints are immediately separated and dried but will become permanent if the surfaces are not separated.

✓ Avoid direct sunlight. ✓ To prevent discoloration, display and store prints as instructed in the documentation supplied with the

media.

Lift the roll and place it on the feeding system. Place back both latches.

6

In the touch panel run the printer in AUTO MODE. In the AUTO MODE settings enter the FEEDING screen. Turn on the feeder and select the direction of rotation (BACKWARDS or FORWARD) depending on how the roll is installed in the feeder. It is normally set a speed of 50% for most fabrics.





FOR THE USER




7

Unwind media by raising the dancing bar while pulling it. The dancing bar will activate the feeder every time it senses the lower sensor. The feeding will stop if the dancing bar reaches its lowest point blocking the upper sensor.





FOR THE USER




8

Unwind enough media to make it go through the banana bar #1 and free roller #1. Regulate the dancing bar’s angle for an easy setting. Pull more media while checking alignments to avoid media shift while feeding.





FOR THE USER




9

Pull more media to make it go through free roller #2, banana bar #2 and the press roller. Regulate the banana bar #2 as shown in the picture below. This banana bar is needed when printing on fabrics with poor tension in the edges. If the edges are properly tensed, then no need to use the bowed part.





FOR THE USER




10

Raise the press roller in the touch panel. Make the media go beneath it.





FOR THE USER




11

Lower the press roller.





FOR THE USER




12

Adjust the EPC sensor. The edge of the fabric should be placed in between the right and left sensor. Use the indicated knob screw (upper picture), to move the EPC sensor closer to the fabric. The using the bottom knob screw, regulate the distance and angle of the EPC sensor (lower picture). Shorten the distance between the sensors if the media’s edge is straight and even. Increase it if the edge is wavy or uneven (using the right knob).





FOR THE USER




13

In the touch panel, running the printer in AUTO MODE double check the press roller is in the lower position, the EPC turned on, the washing unit and the belt dryers turned on as well.





FOR THE USER




14

FOR THE USER




5

Regulate the banana bar’s angle for an easy media setting. Pull more media while checking alignments to avoid media shift while feeding. Make the media go through the first free roller and the expander/extender roller. Raise the press roller and place the fabric beneath it.





FOR THE USER




6

Lower the press roller as indicated below.





FOR THE USER




7

Adjust the EPC sensor. The edge of the fabric should be placed in between the right and left sensor. Use the indicated knob screw (upper picture), to move the EPC sensor closer to the fabric. The using the bottom knob screw, regulate the distance and angle of the EPC sensor (lower picture). Shorten the distance between the sensors if the media’s edge is straight and even. Increase it if the edge is wavy or uneven (using the right knob).





FOR THE USER




8

In the touch panel, running the printer in AUTO MODE double check the press roller is in the lower position, the EPC sensor and the extender roller turned on, the washing unit and the belt dryers turned on as well.





FOR THE USER




9

Move the conveyer forward until the media is positioned below the carriage. Turn on the AUTOMATIC INDRIVING MODE. You are now good to print. When printing the washing unit should automatically be raised and turn its brush. Besides raising its wipers and turning on the belt dryer and the extender roller.





FOR THE USER




10

If the conveyer is too wet even after passing the drying unit, we recommend winding up some media on this roller and place it on the belt as shown in the diagram below. The winded media will absorb the excessive water remaining on the belt before reaching the press roller.





FOR THE USER




Note

If the tension is too low in the feeder side try to increase the breaking power in the clutch by adjusting the pneumatic pressure as shown in the picture below.

Note

If the media’s edges are loose, try to adjust the banana bar’s angle.





FOR THE USER

FOR THE USER




Caution

Be sure that your hands or hair do not get caught in the auto take-up reel unit while it is in operation. Failure to observe this precaution could result in injury.

Important

Do not use a roll core with a deformed interior. If the roll core holder slips, the media may be taken up incorrectly.

Important

We recommend using a take-up roll core with the same width as the media. If a take-up roll core of a different width is used, the take-up roll core may bend, and the media will be taken up incorrectly.

Caution

Please be careful not to trap your hands or fingers when opening or closing the front cover. Failure to observe this precaution could result in injury.

Important

Load media immediately before printing. The pressure rollers may crease media left in the printer. The media may also become wavy or curled, causing jams or resulting in the media coming into contact with the print head.

Important

Do not place exposed media directly on the floor. Media should be rewound and inserted in its original packaging for storage

Important

If media is loaded and the right and left edges of the roll are uneven, media feeding problems may cause the media to move around during printing. Either rewind to align the edges or use a roll without any issues.

Caution

Since the media is heavy, it should not be carried by one person. When loading or removing the media, use at least two persons.

11. NOZZLE CHECK TEST PRINT.

The nozzle check test print allows the user to check the current state of the nozzles in the print head. Helps to determine if the nozzles are firing as they should or not. Probably caused by dried ink or air in the system.





FOR THE USER




1

Once the media is correctly loaded you may proceed to check the media’s width by pressing the button MEDIA WIDTH. The media’s width will be displayed under “MEDIA WIDTH” in mm. Then set the desired point of origin (START POINT).

2

In VALUES MENU screen select test pattern number 1 and then press the TEST PRINT button to print the nozzle check test print.





FOR THE USER




HOW DOES YOUR TEST PRINT LOOKS LIKE?

All the nozzles are firing correctly presenting no gaps in the test print.

A certain number of nozzles are not firing independently from which row number they belong to. A certain number of nozzles may be clogged. Perform several cleanings until getting a perfect test pattern. Is the printer’s negative pressure too high? (Usually a value of -3.50 KPA is used).

One or few couple of missing nozzles affecting both channels equally. Perform several cleanings until getting a perfect test pattern. Move the carriage to the service position (printer’s left end) and check the print head has no scratches.





FOR THE USER




Big number of missing nozzles affecting both channels equally. Perform several cleanings until getting a perfect test pattern. Make sure the ink tubes are free of air and bubbles. Keep service hoses always full on ink and free of air and bubbles. Is the printer’s negative pressure too low? (Usually a value of -3.50 KPA is used). Still can see drops on the head even after wiping it?

Missing nozzles affecting one channel. Perform several cleanings until getting a perfect test pattern. Make sure the ink tubes are free of air and bubbles. Keep service hoses always full on ink and free of air and bubbles. Is the printer’s negative pressure too low? (Usually a value of -3.50 KPA is used). Still can see drops on the head even after wiping it?

One row of nozzles is basically gone. Make sure the gray flat cables are well connected to the head driver board. Make sure print head is well connected to the head driver board. Is the head driver board displaying any alert noise/led? Is that row of nozzles disabled in the JCC? Swap the head driver board with another one and see if the issue moves to the other color.





FOR THE USER




No nozzles being fired. All the nozzles may be clogged. Perform several cleanings until getting a perfect test pattern. Make sure the gray flat cables are well connected to the head driver board. Make sure print head is well connected to the head driver board. Check the head driver board is getting 36 V. Is the head driver board disabled in the JCC? Is the head driver board displaying any alert noise/led? Swap the head driver board with another one and see if the issue moves to the other color.

Another color is detected on the test pattern. Perform several cleanings until getting a perfect test pattern. Make sure the ink in the line is not contaminated with anther color. Make sure the print head is not contaminated with another color. Make sure the print head’s base plate is not contaminated with another color. Make sure the wipers are clean.

A certain number of nozzles are deflected. Make sure the room temperature is cooled. Make sure the ink temperature is cooled. Check the temperature and humidity values are in the operating range. Make sure the ink is not older than one year. Make sure to have loaded the correct waveforms. Use our cleaning solution CL-1000Z. Contact your local dealer or [email protected] for more information.





FOR THE USER




Blank space between row of nozzles. Make sure the bidirectional alignments were correctly performed. BDR value should be the same in both row of nozzles.

12. PURGE AND AUTO-CLEANING.

There are 2 types of print head cleanings. 1. Auto-cleaning. Performed by pressing the CLEANING button in the touch panel. 2. Long purge. Performed by pressing the PURGE button in the touch panel and close the solenoid valves to keep the positive pressure in the heads drip ink constantly.

Auto-cleaning.

The CLEANING button will purge the print heads with ink and automatically wipe them with the automated wiping system.

Long purge.

In case the missing nozzles persists, we recommend the user to follow the following steps.





FOR THE USER




1

Press the PURGE button. The air pump will kick in.

2

Giving approximately 3 to 5 seconds, before the vacuum pumps kicks back, close the solenoid valves by pressing the white LED buttons at the carriage.

3

Keeping the positive pressure between the subtanks and the print heads it is possible to keep them dripping ink. Several subtanks will get empty during this process.





FOR THE USER




4

To stop the heads dripping ink, open the solenoid valves again by switching ON the white LED buttons. Press the HOME button to raise the capping station. Wait until all the subtanks are full and the JETTING message is displayed.

5

Press the CLEANING button to purge and wipe the heads. After this process is done the operator may perform a nozzle check test print to see if the nozzles recovered.

Important

Do not press the CANCEL button when purging ink.

Important

The printer cannot purge or clean the print heads having one of the subtanks empty. To purge or clean the print heads, all subtanks must be full and displaying the JETTING message in the touch panel.

Important

Every time before purging or cleaning the print heads verify the ink drain bottle is empty.

Note

The ink supply pump will be activated 10 times until the subtank is refilled. If the subtank still didn’t get refilled after the 10 attempts, the printer will activate a buzzer and become to a pause. Make sure the Big Ink System has enough ink. Press the INK RESET button in the SETTINGS MENU to activate the ink supply pump another 10 times.

Note

It is possible to purge or clean only one color. Switch OFF the white LED buttons for the remaining colors leaving ON only the color you want to purge or clean. Then do the previously mentioned steps.





FOR THE USER




13. GLOBAL BIDERECTIONAL ADJUSTMENT.

The bidirectional alignment is performed (by a qualified technician) using a specific media and carriage height (usually middle position). If the user wants to change the media’s thickness and/or change the carriage height for whatever reason, the bidirectional compensation factor needs to be regulated to make the heads fire exactly on the same spot when printing from right to left and left to right. After changing the media’s characteristics and/or changing the carriage height is required to check if the machine is still aligned bidirectionally by printing test pattern number 3 in the touch panel.

1

In SETTINGS press the HEAD ALIGNMENT button to enter.

2

In the HEAD ALIGNMENT screen turn ON the TEST MODE and turn OFF the FEEDING functions. Feed a certain length (for example 200mm) at a certain speed and adjust the START POINT. Select TEST PATTERN NUMBER 3 to print the bidirectional alignment pattern. Press the TEST PRINT to print.





FOR THE USER




3

The test print will look something like the image below. Using a loop or a microscope is possible to check the middle line. If BDL and BDR are were not fired on the same spot means the bidirectional compensation factor needs to be corrected.

4

In VALUES menu enter the BI-DIR COMPENSATION screen. Increase or decrease the BI-DIR COMPENSATION value certain units. As a reference, if the carriage was moved to the highest point, a value of 5 is introduced. If I raised the carriage to the highest point, I change only the “BI-DIR COMPENSATION AT HIGH POSITION” parameter. If my carriage is in the middle position, I change only the “BI-DIR COMPENSATION AT MEDIUM POSITION” parameter.





FOR THE USER




5

Repeat steps 1 to 4 adjusting the BI-DIR COMPENSATION value until getting a test print similar to the illustration below.

Important

Do not forget to switch OFF the TEST button and turn ON the FEEDING before resuming production with the new media and/or carriage height.

Note

The carriage height is regulated using the lever located at the left side of the carriage.





FOR THE USER




14. FEED ADJUSTMENT.

Once the feeder and take-up units are correctly adjusted is time to start adjusting the feeding distance more precisely to eliminate the banding effect.

Light band between passes. Means the feeding system has to feed less distance while printing in order to eliminate the distance between passes. To reduce the feeding compensation, in the touch panel press the “VALUES” button and then proceed to press the “minus” button as many times needed until no distance between passes can be seen.

Dark band between passes. Means the feeding system has to feed more distance while printing in order to eliminate the overlap between passes. To increase the feeding compensation, in the touch panel press the “VALUES” button and then press the “plus” button as many times needed until no overlap between passes is shown.

Note

To make the FEEDING COMPENSATION field effective, the PASSES field must have the same number of passes as stated in the RIP software. For example: if my RIP software is using an ICC profile of 4 passes, the PASSES field must have an inputted value of 4. Otherwise the FEEDING COMP. field will not work. Note: even though the resample is ON printing at 8 passes but the RIP software is using an ICC profile of 4 passes, the PASSES field must have an inputted value of 4.

15. PROBLEM SOLVER.

PRINT LOOKS LIKE THIS?

REASON

Missing nozzles on the image. For example, yellow lines can be seen on a red area means a certain number of magenta nozzles are not firing. Nozzles may be clogged. Negative pressure may be unstable.

ACTION

Perform a test print pattern number one. Check for clogged nozzles. Perform several cleanings until getting a perfect test print. Check the RPM and KPA values in the touch panel. Check environmental conditions.


REASON

Big number of nozzles on the image. For example, yellow wide lines can be seen on a red area means a certain number of magenta nozzles are not firing. Nozzles may be clogged. Negative pressure may be unstable.

ACTION

Perform a test print pattern number one. Check for clogged nozzles. Check for air in the system. Check if the negative pressure is too low. Perform several cleanings until getting a perfect test print. Service hoses must be filled with ink. No air in them.


REASON

Intermittent nozzles. For example, yellow lines can be seen on a red area after an indeterminate number of passes. Means one or two magenta nozzles are not firing every after an indeterminate number of passes. Negative pressure may be unstable. Ink demand may be too high.

ACTION

Perform a test print pattern number one. Check for clogged nozzles. Check for air in the system. Check if the negative pressure is too low. Perform several cleanings until getting a perfect test print. Service hoses must be filled with ink. No air in them. Make a new profile that uses a smaller ink quantity of magenta.


REASON Lighter colors between passes. The printer is feeding a longer distance than it should.

ACTION

Check the feeding compensation at 2 passes (in case running with a 2-pass profile). While printing, try to lower the feeding compensation value (in steps of 0.1) in the touch panel until getting no space between passes.





FOR THE USER





REASON Darker colors between passes. The printer is feeding less distance than it should.

ACTION

Check the feeding compensation at 2 passes (in case running with a 2-pass profile). While printing, try to increase the feeding compensation value (in steps of 0.1) in the touch panel until getting no space between passes.

PRINT LOOKS LIKE THIS? REASON

Darker and lighter colors between passes. Inconsistent feeding.

ACTION

Check the pneumatic silver bars are inflated. Check the tension is correct in the media. Check the weights setting is correct in the dancing bars. Check the speed at the take up and feeding units are similar and equilibrated (not too fast or too slow). Perform a feeding motion K value calibration. Check correct tension in the Y feeding timing belts. Check no feeding pulley lost traction from the shaft. Using optimization may resolve the issue.


REASON Some passes are lighter than others. Chromatic banding (soccer filed effect). Bi-directional alignment may be incorrectly done.

ACTION

Chromatic banding (soccer filed effect). Check if using unidirectional printing the issue disappears. Check the bi-directional alignment is correctly done. Perform a scan motion K value calibration. Make sure the room temperature is cooled. Make sure the ink temperature is cooled. Check the temperature and humidity values are in the operating range. See “notes when using the printer” in chapter 2. Make sure the ink is not older than one year. Make sure to have loaded the correct waveforms. May be ink issue. Report us by sending the ink’s batch/lot number. Check you are using d·gen genuine inks. Using optimization may resolve the issue.





FOR THE USER




PRINT LOOKS LIKE THIS? REASON

Ink drops on the print. Pressure in the heads may be too low.

ACTION Make sure all the solenoid valves are open (LED on). Make sure the negative pressure is not too low. Make sure the head’s base plate is not dirty.

PRINT LOOKS LIKE THIS? REASON Stains due to head striking.

ACTION

Heavy amounts of ink may cause waves in the media. Is the carriage height too low? Make sure to change the bi-directional compensation factor to 5 when moving the carriage to the highest point. Is the tension in the media too low? If media is stored inappropriately or left loaded in the printer, wrinkles and waviness may occur. If media is used in this state, the print head and the raised surface of the media may contact and cause staining. If the media loading method, heating temperature, tension and other settings are inappropriate, wrinkles and waviness occur on the media. Make sure media is being loaded on the auto take-up reel unit correctly.


REASON Blurry images and low sharpness. Carriage angle may be not aligned. Bi-directional alignment may be incorrectly done.

ACTION

Check if using unidirectional printing the issue disappears. Make sure to redo the bi-directional alignment. Make sure the belt in the carriage has the proper tension. Try to perform a scan motion K value calibration. Check the encoder strip is cleaned.
