General Description of Errors
981093 – October 1994 3
General Description of Errors
Errors • Error codes represent an error or non-standard condition of the PROCESSOR. For further
information, see the tables starting on page .
• Error codes are indicated by blinking LEDs on the DISPLAY PANEL.
• If a non-fatal error or a non-standard condition occurs when film is fed, the ALARM will beep
twice. See Table on page .
• Error codes are listed by order of priority.
• When 2 or more errors occur at the same time, only the highest priority error is shown on the
DISPLAY PANEL.
• When the higher priority error or warning is corrected, the next priority error or warning code is
then displayed on the DISPLAY PANEL.
• Errors are divided into 3 categories:
– Fatal Errors
– Non-Fatal Errors
– Warnings
• Processing films during an error or non-standard condition may affect the image quality.
Fatal Errors
A Fatal Error is any error or non-standard condition that, once detected, causes the PROCESSOR to
enter a protective mode to prevent a hazardous condition. If the PROCESSOR is in a Fatal Error
Condition, record the error code indicated by the number of blinks on the SERVICE INDICATOR and
move the MAIN CIRCUIT BREAKER CB1 to the “O” position.
For Error 1 — If the error occurs while the PROCESSOR is in standby, the PROCESSOR will not
accept any film. The operator cannot correct the error.
For Errors 02 - 04 — If a sheet of film is in transit through the PROCESSOR when these errors occur,
the sheet of film will exit from the PROCESSOR, the PROCESSOR will shut down, and the
PROCESSOR will not accept any more sheets of film. If while the first sheet of film is in transit
through the PROCESSOR, the operator inserts additional sheets of film, the PROCESSOR will:
• operate with the non-functional component disabled
• sound the ALARM in a pattern of 2 seconds on and 2 seconds off
• shutdown after all additional sheets of film exit the PROCESSOR
For Errors 05 and 06 — The transport system will continue to operate. If the operator feeds film while
the PROCESSOR is in this condition, the film will exit wet. See Table on page for a description of
the PROCESSOR’S operation under Fatal Error conditions. If film is moving through the
PROCESSOR, the AUDIO ALARM will sound, in a pattern of 2 seconds ON and 2 seconds OFF, until
the film exits the PROCESSOR.

SITE SPECIFICATIONS
4October 1994 – 981093
Non-Fatal Errors
A Non-Fatal Error is any error or non-standard condition that can sometimes be corrected by the
operator. The PROCESSOR will attempt to correct the problem and will not enter into a protective
mode.
The PROCESSOR will usually accept film and continue to operate, but the image quality may be
reduced. As long as the error condition exists, the PROCESSOR will sound the ALARM twice
whenever the FILM SENSORS detect a leading edge of film being fed into the PROCESSOR. The
operator may be able to resolve the error condition by consulting the Operator Manual Publication No.
981089.
Warings A Warning is any error that the operator may be able to correct and normally does not prevent the
PROCESSOR from accepting film.
The PROCESSOR can continue to operate, but image quality may be affected. As long as the error
condition exists, the PROCESSOR will sound the ALARM twice whenever the FILM SENSORS
detect a leading edge of film being fed into the PROCESSOR. The error is a temporary condition or
one that the operator may be able to correct.

Troubleshooting Procedures
Checking the SOLID STATE RELAYS for Correct Operation
Possible damage from electrostatic discharge.
ESD
[1] Measure the voltage between CONTACTS 1 and 2. See the figure.
(a) If the controlled component should be operating, you should measure +5 V DC at CONTACTS 3 and 4,
and a voltage of no more than 2 V AC at CONTACTS 1 and 2. If you measured more than 2 V AC at
CONTACTS 1 and 2, install a new RELAY and a new MOV.
(b) If the controlled component should not be operating, you should measure an AC voltage equal to the AC
supply voltage. If you measured an AC voltage of less than the AC supply voltage, install a new RELAY
and a new MOV.
[2] If the tests done in both Steps a and b passed, the failure is not the SOLID STATE RELAY, but the WIRING
HARNESS or the controlled component.
(a) Remove the MOV. Check the MOV for continuity.
If continuity, install a new MOV.
If no continuity, install a new RELAY and a new MOV.

1. Check that the main water supply to the PROCESSOR is turned on.
2. Check that the WASH DRAIN VALVE and the DEVELOPER DRAIN VALVE are
closed and not leaking.
3. Check that the solution in both the DEVELOPER TANK and the WASH TANK is
at the correct level.
4. Check whether the temperature conditions outlined below are met:
• the main water supply is 5°C (8°F) lower than the developer set-point
temperature, between 4°and 29°C (40°and 85°F).
• the room ambient temperature is not greater than 30°C (86°F).
5. Check the set-point temperature of the DRYER. If the ambient temperature of your
site is in the lower end of the acceptable range of 15 to 30°C (59 to 86°F), the
PROCESSOR may never enter the Standby Mode, which could cause the developer
temperature to become too hot. This is true especially if the ambient water
temperature is higher than 26.6°C (80°F).
6. Check the wash and developer plumbing for leaks, air bubbles, or kinks in the
HOSES.
7. Check the ORIFICE in the DEVELOPER RECIRCULATION HOSE for any dirt or
obstructions.
• Note: The white ORIFICE is for fixer; the black ORIFICE is for developer.

9. Check that the WASH PUMP is not airlocked.
10. Check that the DEVELOPER RACK and the FIXER RACK are not interchanged.
You can identify the DEVELOPER RACK by the following characteristics:
• red WIRE TIE
• RACK COVER
11. If the DEVELOPER RACK and the FIXER RACK are interchanged, do the steps
below:
• Check that the developer and fixer processing solutions have not become
contaminated. If necessary, drain, rinse, and fill the DEVELOPER and FIXER
TANKS.
• Rinse the RACKS.
• Install the RACKS into the appropriate TANKS.
12. Before installing the DEVELOPER RACK into the DEVELOPER TANK, do the
steps below:
• Check that the MANIFOLD on the DEVELOPER RACK is not loose.
• Insert the INTERLOCK TOOL TL-4740 into the AC INTERLOCK SWITCH
S5, and check that the DEVELOPER RECIRCULATION PUMP is operating
correctly and that the developer solution is circulating.
• If the PUMP is not operating, check the wiring and the AC INTERLOCK
SWITCH S5.
• Remove the INTERLOCK TOOL and install the DEVELOPER RACK.
13. Check that FUSE F1 is not open. If necessary, replace F1 it with a correct size Slo-
Blo FUSE (2.0 AMP for M43A and Clinic 1; 1.0 AMP for M43)
14. Check that J103 is connected securely to the 100 CIRCUIT BOARD.

15. Use the Service Routine for the WATER INPUT SOLENOID to check whether the
SOLENOID is operating.
• If the SOLENOID is not operating, clean the WASH INLET BAR and the
SCREEN on the SOLENOID. Check that the voltage across the SOLENOID is
20 V DC for one second, then decreases to a holding voltage of 4 V DC, and then
decreases to 0 V DC when off.
• Check for 65 Ω±5% at COIL L1 of the WATER INPUT SOLENOID.
If necessary, install a new WATER INPUT SOLENOID.
16. Use the Service Routines as described in Table on page .
• For the WASH PUMP to check that SSR-U4 for the WASH PUMP is operating
and that cooling water is circulating.
• If the WASH PUMP is not operating, check for dirt or obstructions in the
DIVERTER VALVE in an M43 or M43A, or in the ORIFICE in a Clinic 1; and
clean the holes in the WASH TUBES.
• On an M43 or M43A PROCESSOR, check that the DIVERTER VALVE is
wired and operating correctly:
• the red and black wires should connect P/J20 to the outer COIL, COOLING
DIVERTER SOLENOID L2
• the green and white wires should connect P/J21 to the inner COIL, WASH
DIVERTER SOLENOID L3
• Check that the actual plumbing of the DIVERTER VALVE matches the
plumbing diagram in the Diagram Package, Publication Number 981092.
• Measure the voltage across the outer COIL, SOLENOID L2. The voltage should
be 20 V DC for one second, then decrease to a holding voltage of 4 V DC, and
then decrease to 0 V DC when off.
• If you did measure the correct voltage, measure the resistance across
SOLENOID L2 by doing the steps below.
• 1. Disconnect 1 of the LEADS from SOLENOID L2.
• 2. Measure the resistance of SOLENOID L2. The resistance should be
19 Ω±10%.
• 3. If necessary, install a new SOLENOID L2.
• 4. Connect the LEAD to SOLENOID L2.
• If you did not measure the correct voltage, continue doing the steps below until
you identify the problem.
• 1. Check the connection at the 100 CIRCUIT BOARD.
• 2. Install a new SOFTWARE PROM U5.
• 3. Install a new 100 CIRCUIT BOARD.
17. Use the procedure on page to check SSR-U3 for the DEVELOPER HEATER.
18. Use the procedure on page to measure the resistance at the DEVELOPER
THERMISTOR. Compare your reading to the values in Table on page .
• If the resistance is not within ±10% of the correct resistance given in Table ,
install a new DEVELOPER THERMISTOR.
19. Check that the resistance of the DEVELOPER HEATER, at a room temperature of
21°C (70°F), is 62 Ω±5% for the M43 and 16 Ω±5% for the M43A and Clinic 1.
20. Check that the line voltage is within specification.
