Note:
1. The EEPROM on the DC controller PCB contains various data (e.g., registration
adjustment values) of each machine model. If you are replacing the DC controller
PCB, be sure to transfer the data to the new DC controller PCB as instructed under
I.A.1. "Replacing the DC Controller PCB" in Chapter 10.
2. Upon detection of E000, E001, E003, E004, E009, or E808, the printer unit issues
a service person call and then turns itself off in 20 sec.
3. In the case of a fault associated with E001 or E003, the data may be stored in the
error memory capacitor (C259) on the DC controller PCB. After removing the
cause, be sure to discharge the capacitor. (Short JP201 on the DC controller PCB
to discharge C259; see p. 10-80.)
4. The machine's laser/scanner assembly and intermediate transfer drum unit are not
designed for adjustment in the field. Do not disassemble them. (However, the sec-
ondary pre-transfer charging assembly inside the intermediate transfer drum may
be replaced.)
5. The control panel of the printer unit indicates error codes associated with the print-
er unit; if the reader unit is installed, error codes related to the reader unit will be
dealt with by indicating "SERVICE CALL CHECK READER.
• The control panel of the reader unit indicates error codes associated with the
reader unit. Check the code, if any, and work according to the instructions in the
Reader Unit Service Manual.
