Error Codes
5B6342 – January 1996 3
Section 1: Error Codes
Introduction
Overview The software on the 5000 MICROPROCESSOR BOARD controls and monitors the operation
of the PROCESSOR and continually checks for errors. When an error occurs, a description of
the error is displayed on the DISPLAY PANEL.
When 2 or more errors occur together, all the errors are displayed, but only 1 error is visible on
the DISPLAY PANEL at a time. The error with the highest priority is displayed first. You can
scroll through the list to view the other errors.
An error log on the 5000 BOARD records the last 100 errors that have occurred and the
number of times each error has occurred.
3 types of errors can occur:
• Fatal
• Non-Fatal
• Warning
Fatal and
Non-Fatal Errors Only qualified service personnel should repair both fatal and non-fatal errors. • Most fatal errors prevent optimum film processing.
• Most non-fatal errors do not prevent optimum film processing.
Important
When you service a PROCESSOR with a fatal or non-fatal error and you check an electrical
component or BOARD, also check all the:
• connections and CABLES for the component or BOARD
• voltages from the POWER SUPPLY for the component or BOARD
Warning Errors Operators can repair warning errors. Normally, you can feed film into a PROCESSOR when a
warning error is displayed.
READY LED If any error prevents optimum film processing, the READY LED will de-energize. When the
LED de-energizes, you can feed film into the PROCESSOR but the image quality may not be
correct. Kodak recommends that you do not process film when the LED is de-energized.

DIAGNOSTICS
4 January 1996 – 5B6342
All Errors
Important
When you check an electrical component or BOARD, also check all the:
• connections and CABLES for the component or BOARD
• voltages from the POWER SUPPLY for the component or BOARD
When you check a SOLID STATE RELAY, use the tests in the Appendix to determine the source of the malfunction.

E013 Level sensor circuit failure This error occurs when the level sensor circuit on the 5000 BOARD
malfunctions. The following parts are disabled:
• DEVELOPER and FIXER REPLENISHMENT PUMPS
• RECIRCULATION PUMP
The temperature control for the fixer and developer is disabled.
5000 BOARD Install a new BOARD.
E014 Invalid program software E014 is displayed on the DEVELOPER TEMPERATURE DISPLAY. This
error disables all subsystems, except communications.

E015 Invalid bootstrap software The bootstrap software for the
PROM U5006 on the 5000
BOARD
Install a new U5006.
E016 Invalid film accumulator
software This error does not disable any subsystems. The PROCESSOR will remain in the standby mode until the FILM DETECTOR SWITCHES actuate. These
SWITCHES provide information about the length of the film. Because the
6000 BOARD does not operate correctly, the PROCESSOR uses the
information from the SWITCHES to determine the replenishment rate.

DIAGNOSTICS
10 January 1996 – 5B6342
Code Description Possible Malfunction Action
E041 Loss of transport speed control
Note
This error occurs when the
transport speed is adjusted for
10 seconds and the speed is
not within 7.6 cm/min (3 in./min)
of the setpoint.
When the PROCESSOR operates normally:
• The supply voltage from the +24 V POWER SUPPLY PS3 to the
PCOM and +24 V TERMINALS of the DRIVE MOTOR
CONTROLLER A4 is 24 V DC.
• The control voltage to TERMINALS 4 and 6 on the DRIVE MOTOR
CONTROLLER A4 is approximately:
– 0.85 V DC for the Extended Speed
– 1.55 V DC for the Standard Speed
– 2.25 V DC for the Rapid Speed
– 3.00 V DC for the K/RA Speed
• Feedback pulses from the DRIVE MOTOR CONTROLLER A4 at
Test Point MOTFB on the 5000 BOARD indicate the speed of the
DRIVE MOTOR.
If the transport operates slower than the set speed, the
MICROPROCESSOR increases the control voltage approximately
25 mV every second at TERMINALS 4 and 6 on the DRIVE MOTOR
CONTROLLER A4. If the voltage reaches 5 V DC, the
MICROPROCESSOR stops increasing the voltage. When you check
the voltage, if it is:
• 5 V DC, check for mechanical malfunctions.
• 0, check the wiring and the CONNECTOR.
5000 BOARD If the control voltage is not correct at
TERMINALS 4 and 6 of the DRIVE MOTOR
CONTROLLER A4, install a new BOARD.
DC DRIVE MOTOR B6 or
DRIVE MOTOR
CONTROLLER A4
If B6 operates, but no pulses occur at Test
Point MOTFB on the 5000 BOARD or if the
supply voltage and the control voltage to the
CONTROLLER are not correct, check:
• B6
•A4
E042 Loss of accessory data link Loose connections Check all connections between any
accessory and the PROCESSOR.
