3,0XX.6x Errors - IPC Program Faults

4,0XX.4x Errors - Process Control System Fault

3-10
There is a communication problem between the engine and PostScript
regions.
a. Reset NVRAM, and then retest.
b. Replace the EEPROM chip.
4,017.47: This fault code indicates a problem with the process control system.
The ambient temperature is considered too cold to warm up the printer (less
o
than 10 C).
4,018.48: This fault code indicates a problem with the process control system.
The Printhead temperature dropped below the head cleaning needed
threshold.
4,020.41: This fault code indicates a problem with the process control system.
Declared when the printer is booted in FTTR (Fast Time to Ready) mode and
the head/wiper contact flag is set in NVRAM. The printer cannot run in FTTR
mode with the head/wiper in contact because it would be unwise to separate
the two when the printer is cold (could tear wiper.) Service requested that this
be a device fault in order to alert the service person to this condition.
4,021.42: This fault code indicates a problem with the process control system.
Declared when the printer is booted in FTTR mode and the Drum is dirty.
Cleaning the Drum when very cold could increase the chance of gluing media
to the Drum surface around the stripper fingers. Service requested that this be
a device fault in order to alert the service person to this condition.
Troubleshooting Procedure for Process Control System
Step Questions and Actions
1. Verify the temperature of the room where
1
the printer is located (see "Environmental
Specifications" on page 1-12).
2. Is the room temperature too cold?
3. Ensure the printer is acclimated to the
room temperature.
Did this correct the problem?
Run the Monitor Heaters tests with all
2
heaters ON.
Are the heaters operating correctly and
within specification?
Inspect the harness to the failed heater.
