1. PROCESSOR IS TOTALLY INACTIVE ( No Lights )
A. Check that the power switch is turned ON .
B. Check that the line cord is connected @ both the Base & wall outlet.
C. Check that the Electronics Module cable @ connector J1 is properly attached.
D. Check the fuse; If blown, replace with 8A / 250V 5mm Slow-Blow type (p/n 41914).
E. Check for loose connections and/or wires in Base, and using the TEST POINT CHART on page 19;
1. Check the voltage at connector J1, pins 1 & 3, on the Base – If the voltage is between 103.5 and
126.5VAC, replace Electronics Module (p/n 45415).
2. If no voltage is detected, check the output side of the IEC/RFI filter for voltage. Unplug the line
cord from the processor, remove the two fastening screws, and slide out the IEC/RFI filter. Plug line
cord back into the filter and check for voltage across the black (hot) and white (neutral) leads;
a. If the measured voltage is between 103.5 and 126.5VAC, unplug line cord and check for
continuity between black (hot) on filter & pin 1 @ J1, and continuity between white (neutral)
on filter and pin 3 at J1.
b. If the measured voltage is NOT between 103.5 and 126.5VAC, replace IEC/RFI filter (p/n 45975)
2. PROCESS CYCLE WILL NOT START (When inserting a film into film inlet - No drive, dryer, etc...)
A. Check that the Top Cover assembly is seated squarely on the Base – If not, the interlock switch may
not be engaged which will prevent the transport drive motor from running.
B. Check the Film Shutter assembly freely pivots and is not jammed – Remove Cover Tray for service;
1. If difficult to pivot, clean shutter hinges with a moist sponge and thoroughly dry.
2. If jammed or abnormally bent, try to re-shape the shutter flag and align as depicted by DETAIL “B”
and DETAIL “C” in the COVER ASSEMBLY section (page 46). With shutter in closed position, the
flag must be fully inserted into the PCB optic sensor. With shutter in open position, the flag must
be fully out of the PCB optic sensor. If Film Shutter is uncorrectable, replace the component (p/n
43584)
C. Check electronics function and using the SYSTEM SCHEMATIC – Remove Electronics Module from
top cover but leave connected @ J1. Disconnect J8 (green, blue, yellow wires) & depress the CLEANING
CYCLE button on keypad;
1. If difficult to pivot, clean shutter hinges with a moist sponge and thoroughly dry.
2. If processor DOES NOT start, replace Electronics Module (p/n 45415)
3. PROCESS CYCLE WILL NOT STOP (Process cycle continues indefinitely)
A. Reset processor by placing POWER switch to ON while depressing SET TEMP button for 3 seconds.
B. Check the Film Shutter assembly is not stuck on the Developer Transport rack entry roller, if so;
1. Inspect transport for squareness
2. If Shutter Guard is bent and contacts the transport, restore as required to eliminate contact.
C. Check the Film Shutter assembly freely pivots and is not jammed – Remove Cover Tray for service;
1. If difficult to pivot, clean shutter hinges with a moist sponge and thoroughly dry.
2. If jammed or abnormally bent, try to re-shape the shutter flag and align as depicted by DETAIL “B” and
DETAIL “C” in the COVER ASSEMBLY section (page 46). With shutter in closed position, the flag
must be fully inserted into the PCB optic sensor.With shutter in open position, the flag must be
fully out of the PCB optic sensor.
3. If Film Shutter is uncorrectable, replace the component (p/n 43584)
D. Check the PROCESS LED; If it's flashing, refer to troubleshooting item 2C above.
