Code
E804
Caution:
1. The copier may be reset by turning its power switch off and then on when its self
diagnostic mechanism has turned on. This, however, does not apply to E000, E004, E005,
E008, E020 (if xxE0), or E717. This is to prevent possible damage by an overheating
fixing roller occurring if these errors were designed to be reset while the thermistor has an
open circuit.
2. If E005 (no cleaning belt) is indicated, replace the cleaning belt, and be sure to reset the
fixing cleaning belt counter in service mode (COPIER>COUNTER>MISC>FIX-WEB).
Resetting E000, E004, E005, E008, E020, or E717
1) Start service mode, and select COPIER>FUNCTION>CLEAR>ERR (to highlight).
2) Press the OK key.
3) Turn off and then on the power switch.
E717
E717 may be prevented by temporarily disconnecting the communication line using service
mode as follows before disconnecting the copy data controller or the remot diagnostic device
connected to the copier:
1) Start service mode, and select COPIER>OPTION>IN-FACE>B-CLR (to highlight).
2) Enter '0', and press the OK key.
3) End service mode, and perform appropriate servicing.
