Timings


• Geometric Correction:


To correct irregularities in the polygon run, the digitizer measures the timings between the BOL and EOL signal during each scan. Certain irregularities, which may be caused by external vibrations or the polygon ball bearings are smoothed by calculating mean values of several scan lines.

• Jitter Correction:

To correct irregularities in the optical path, the digitizer measures at each boot-up the timings of the laser beam between pin diode 1 and 2, 2 and 3 and so on.As a result a kind of "calibration curve" is created, which corrects possible distortions.



• Synchronization of Polygon, Begin of Scan, Begin of Line and AD Window :

When an IP is inserted the polygon starts up. The BOL/EOL sensors measure the position of the polygon mirrors (they even detect each single facet). When the IP arrives for scanning, the sensors of the calibration board detect the IP edge and generate the begin of scan signal (BOS).The begin of line signal (BOL) triggers a timer for switching on the laser beam and the AD window. The length of the AD window and "Laser On" depends on the image plate size.


Digitizer Introduction: Stall Detection (1)

Stall detection (= load detection) • Motor stall (home/end position) detection without the use of

additional sensors • Made by evaluation of stepper motor control curve on the

motor controller chip

Advantage (compared to home/end position detection via light sensors):

• Monitoring of motor run not only in home and end position, but also between home and end position (except acceleration / deceleration time)

• Less sensors (costs, reliability) and cabling (costs).

Signal correction before scan: AUTOZEROWith laser and blue LED switched off, the system measures the output of the PMT. This value is the AUTOZERO value.Parameters: Noise of the PMT electronics; Remaining light Error message if AUTOZERO value exceeds certain limit (e.g. covers opened)

Signal corrections during scan: AUTOCALDuring laser blank time, till the next facet scans a line, the blue LED is switched on to measure the sensitivity of the PMT. By combining the measured values of several lines the sensitivity is automatically adjusted (High Tension at PMT)

Repair

• Calibration & Adjustments• Spare Parts• E-Labels• SW Update/Upgrade


Repair: Calibrations and Adjustments

Adjustment To be done in case ....

Drawer Unit Height Adjustment After replacement of the drawer unit

PMI board carrier position adjustment After replacement of the PMT with light collector

Cassette edge sensor position adjustment

After replacement of cassette edge sensor

Exceptionally:

Cassette unit open safety switch position check

After replacement of cassette unit open safety switch

Details see chapter 3.6, Technical Documentation

Calibration To be done in case ....

Shading calibration After replacement of the PMT with light collector

After replacement of the optic module Whenever the PMT or light collector have

been removed (e.g. for replacing the slow scan module)


Repair: Spare Parts

• Alltogether 34 Spare Parts (Status 07/2006)• Recommended spare part:

"Small parts Kit, CM+XYZ"• Repairable parts (to be sent back):

• Optic module• Slow scan unit• Cassette opener unit (with IP handling board)


Repair: E-Labels (1)

• Following PCBs are equipped with E-Lables:• PMT• PMI Board• Slow Scan Board• IP Handling Board• Optic Module PCB

• E-Label contains module specific data



1. Spare part (e.g. Slow scan board) is part of a larger module and requires module specific data:

• E-Label on Board gets SN 9999 in production

• This is the trigger for the processing station to copy the module specific data to the E-Label of the board.

Two exchange scenarios: Examples:



2. Spare part is an adjusted module (e.g. slow scan unit) which has its own module specific data:

• E-Label on Board gets SN 2345 in production (2345 is just an example)

• This the trigger for the processing station to copy the module specific data from the E-Label to the processing station for backup reasons

Two exchange scenarios: Examples:



Consequence of the two exchange scenarios:

Following kinds of exchange are not allowed:

• Do not use a "Slow scan board" or "IP handling board" from another digitizer.

• Do not use a "Slow scan board" which is originally part of a spare "Slow scan module" to exchange the "Slow Scan board" only.

• Do not use an "IP handling board" which is part of a "Cassette fixation unit" to replace the "IP handling board" only.


Repair: Software Update/Upgrade


Maintenance

• Each 12.000 cycles / once a year• Indicated via message at processing station

(can be de-activated: CR30-X Service Client Maintenance Indicator)

• No preventive replacements !• Main Tasks
