C-2451 - When the developing motor/Y
(M20) is ON, the maximum
detection value of TCR sensor/Y
(TCRS/Y) is the specified value
and the difference between the
maximum detection value and
the minimum detection value is
over the specified value.

relavant parts:
Printer control board (PRCB)
Developing motor/Y (M20)
TCR sensor/Y (TCRS/Y)

- first check that the motor is turning correctly, clean sensor, check toner pipes, that the toner is rally moving from hopper to developing unit.

120.10 service fuser error

This error means the Fuser module is not able to reach the temperature required to work or there is a problem with the power. This is not an user-serviceable part. The only way to fix it is requesting the part and having a technician to fix it.

If the machine is more than 5 years old, is a good idea to consider to buy a new one as the part is quite expensive.

My machine shows the E005 error. I found some solutions from your site. You told to replace the web. I don't know what is web and how to reset my machine

Wich copier is it?

Web roller is some kind of cleaning belt in fixing assy, above fixing roller. After you replace it you need to clear it in service mode.

If you want to do it yourself, send mail on and Ill send you service manual.

most times eoo1 can be reset in service mode if there is no damage to fixing unit. 1) Enter service mode.
Press the operation panel user mode key, 2 key, 8 key and user mode key in this order.
2) scroll to "clear" and press ok then scroll to "err" and press ok.

if that does not work you can go back into service mode as above and instead of scrolling to "err" scroll to "all" and press ok. power off then on. doing this will clear settings service techs might have made but i've done quite a few and had no probs
