Upgrade the firmware if it was not upgraded in a previous step. Note: Contact your next level of support for the correct firmware level to use. 2. POR the printer. 3. Send the printer a print job. Does the error remain? Go to step 11. The problem is solved. Step 11 Is there optional memory installed? Go to step 12. The problem is solved. Step 12 1. Reinstall the first internal option. 2. POR the printer. Does the error remain? Go to step 14. Go to step 13. Step 13 1. Run a job to test the option. Does the error remain? Go to step 14. Go to step 16. Step 14 1. Upgrade the firmware if it was not upgraded in a previous step. Note: Contact your next level of support for the correct firmware level to use. 2. POR the printer. 3. Send the printer a print job. Does the error remain? Go to step 15. The problem is solved. Step 15 1. Replace the faulty internal option. 2. POR the printer. Does the error remain? Go to step 21. Go to step 16. Step 16 Are there any more internal options to install? Go to step 17. The problem is solved. Step 17 1. Install the next internal option. 2. POR the printer. Does the error remain? Go to step 19. Go to step 18. Step 18 Run a job to test the option. Does the error remain? Go to step 19. Go to step 16. Step 19 1. Upgrade the firmware if it was not upgraded in a previous step. Note: Contact your next level of support for the correct firmware level to use. 2. POR the printer. 3. Send the printer a print job. Does the error remain? Go to step 20. Go to step 16. Step 20 1. Replace the faulty internal option. 2. POR the printer. Does the error remain? Go to step 21. Go to step 16. Step 21 Contact your next level of support. You will need the following information: • Exact 900.xx error digits and complete error message • Printed menu settings page • Printed network settings page • Device error log • A sample print file if the error appears to be isolated to a single file • File/Application used if the error is related to specific print file • Device operating system • Driver used (PCL/PS) • Frequency of the occurrence of the error
Code: 912.xx
Description: Unrecoverable Engine firmware error POR the machine. If the error re-occurs, then update the firmware. If the error continues occurring, then replace the controller board.
Remedy: Controller board removal.
Code: 940.xx
Description: RIP to engine communication failure-the zero crossing signal used for fuser control in the low voltage (LV) power supply has failed, or the wrong low voltage power supply has been installed.
Remedy: Step 1 1. Check the power cord for continuity. If necessary, replace. 2. Make sure the nominal voltage source is within specification. See Electrical specifications. Does the problem remain? Go to step 2. The problem is solved. Step 2 Check if the power supply cable is properly connected to the controller board. Is it properly connected? Go to step 3. Reseat the cables. Step 3 1. Turn off the printer. 2. Remove the power cord. 3. Measure the resistance between terminals A and D of the power supply socket. Is the resistance approximately 30 ohms? Contact your next level of support. Replace the power supply. See Power supply removal.
Description: Failed engine card-delay line calibration failure.
Remedy: Replace the controller board.
Code: 950.xx
Description: NVRAM mismatch failure - mismatch between controller board EEPROM and control panel mirror. ".xx" codes: • 00-29 - mismatch between system and mirror • 30-60 - mismatch between secure and system
Remedy: Warning - Potential Damage: When replacing any of the following components: • Control panel assembly • Controller board assembly Replace only one component at a time. Replace the required component and perform a POR before replacing a second component listed above. If this procedure is not followed, the printer will be rendered inoperable. Never replace two or more of the components listed above without a POR after installing each one or the printer will be rendered inoperable. Warning - Potential Damage: These components can be used as a method of troubleshooting as long as the machine is booted into diagnostic mode or is operating in diagnostic mode. Once a component has been installed in a machine and powered up into user mode, it cannot be used in another machine. It must be returned to the manufacturer. Step 1 Check the control panel assembly. Was the control panel assembly recently replaced? Go to step 3. Go to step 2. Step 2 Check the controller board assembly. Was the controller board assembly recently replaced? Go to step 4. Contact next level of support. Step 3 Replace the current control panel assembly with the original control panel assembly. Go to Control panel assembly removal. Does the error remain? Go to step 5. The problem is solved. Step 4 Replace the current controller board assembly with the original controller board assembly. Go to Controller board removal. Does the problem continue? Go to step 6. The problem is solved. Step 5 Replace the original control panel assembly with a new and not previously installed control panel assembly. Does the error continue? Contact the next level of support. The problem is solved. Step 6 Replace the original control panel assembly with a new and not previously installed control panel door assembly. Does the error continue? Contact the next level of support. The problem is solved.
