3 Safety: Working with the Digitizer (2) Safety Directions are divided in "Generic Safety Directions" (Chapter 0) and product specific safety directions (Chapter 3.1)The following charts list the product specific safety directions which are important for this training.
14 Service KPI's CR30-X MTTI (Mean Time To Install) = 0.33 h / one person MTTM (Mean Time To Maintain) = 1.5 hours incl. Quality checkMTBM (Mean Time Between Maintenance) = 1 yearMCBM (Mean Cycles Between Maintenance) ≥ cyclesMTTR (Mean Time To Repair, includes MFDT) < 1.5 hService support time, parts availability = End of production + 7 yearsMTTT (Mean Time to Train) – technical training = 2 d IBT / 1 d WBT
15 Service Strategy Service Target Groups: Agfa FSEs 3rd party and dealer service engineersOne day Installation Concept:Staging as far as possibleBasic exam tree in English with CR30-X and Drystar 5302Further adjustments via professional service (Agfa Application specialist)Repair:Replacements mainly on module level (where useful)No adjustments after replacements (3 exceptions)

19 Digitizer Introduction: Controls and Connections
36 Digitizer Introduction: Scan Principle (4) Geometric 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.Jitter 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.
37 Digitizer Introduction: Scan Principle (5) 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.
38 Digitizer Introduction: Stall Detection (1) Stall detection (= load detection)Motor stall (home/end position) detection without the use of additional sensorsMade by evaluation of stepper motor control curve on the motor controller chipAdvantage (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).
47 Digitizer Introduction: Hardware Modules (7) PMT with Light Collector
48 Digitizer Introduction: Hardware Modules (8) Functions of the Blue LED in the Light Collector 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)Blue LED

51 Digitizer Introduction: Bootup Boot-up takes approx. 60 sec.During bootup the digitizer status is only displayed at the processing station if an error occursLink to detailed boot-up procedure (see also printed version in Technical Documentation chapter 2; Bootup)

59 Repair Calibration & Adjustments Spare Parts E-Labels SW Update/Upgrade
60 Repair: Calibrations and Adjustments To be done in case ....Shading calibrationAfter replacement of the PMT with light collectorAfter replacement of the optic moduleWhenever the PMT or light collector have been removed (e.g. for replacing the slow scan module)Details see chapter 3.6, Technical Documentation
61 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 moduleSlow scan unitCassette opener unit (with IP handling board)
62 Repair: E-Labels (1) Following PCBs are equipped with E-Lables: PMTPMI BoardSlow Scan BoardIP Handling BoardOptic Module PCBE-Label contains module specific data
63 Repair: E-Labels (2) Two exchange scenarios: Examples: 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 productionThis is the trigger for the processing station to copy the module specific data to the E-Label of the board.
64 Repair: E-Labels (3) 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
65 Repair: E-Labels (4) 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.
