CHAPTER 13 TROUBLESHOOTING
Notes:
1. When the self diagnostic mechanism has turned on, you can reset the copier by turning on
its power switch once. This, however, is not true of E000, E001, E002, E003, E004, E005,
E013, E020 or E717. (Otherwise, the user could reset the copier while a thermistor may
have an open circuit, causing the fixing roller to suffer thermal damage or toner inside the
hopper to overflow; this consideration, however, dose not apply to E717)
If the error is E000 through E003, the power switch will turn off automatically in about 20
sec if you turn it on without resetting. In the case of E004, on the other hand, the power
switch will turn off in about 5 sec after E000 is indicated if you turn on the power switch
without resetting.
You will have to initialize the RAM on the DC controller PCB if E000, E001, E002, E003,
E004, E005, E013, E020, or E717 is indicated.
Resetting the Copier
1) Execute COPIER>FUNCTION>CLEAR>ERR in service mode.
2) Press the Reset key twice to return to the Copy Mode screen.
3) Turn off and then on the main power switch.
2. For E202, and E204, you can check codes in service mode (COPIER>DISPLAY>
ERR).
In the case of E202 or E204, the control panel will show the following:

3. E677
• If it occurred when the main power is turned on,
The problem is likely to be a hardware problem. ‘E677’ also occurs when the power switch
is turned off and then on too quickly, because of the difference in timing at which the main
body and the printer board are initialized. (Be sure to wait for 5 sec or more before turning
on the power after turning it off.)
• If it occurred during operation,
If it occurred during printing operation and is corrected when the job is canceled and the
power switch is turned off and then on, the problem is likely to be an excess load on the
CPU.
If an excess load is imposed on the CPU on the printer board, as when a large amount of
print data is processed while a large amount of data is received from the network, ‘E677’
can occur, although rare.
If this is the problem, cancel all print jobs, and turn off and then on the main power switch;
advise the user to send print data in single units.
