COF37 error code

Can you tell me how to fix this code so I don't have to call a rep.? It prints blank copies when you tell it to make a black copy and it prints very faint when you tell it to print a color copy.

C0F37: Abnormally high toner density detected by Black ATDC Sensor
Toner density that is 4 % or more higher than the target level is detected ten consecutive times during a printCOF37 error code - 1.gif cycle, ATVC, or image stabilization sequence.

The sensor for this error is in the black imaging unit not the toner hopper. See the steps below. If that doesn't work then visit my website1.gif for contact and I will sell you a full service and or parts manual on CD.

Have a Canon MP830. in the middle of printing, it came up with error code 6A00, and now all it does is flash the alarm light and copy light. how to fix?


http://www.usa.canon.com/cusa/support/consumer/printers_multifunction/pixma_mp_series/pixma_mp830#BrochuresAndManuals

I would download the manual for windows 7 and see if the 'alarm and copy light flash' error is listed. I could not find it referred to in the support area of the canonusa.com website. Also, you could call 1-800-OK CANON and talk to a rep. about this problem.

Good luck on this repair.

We have a xerox 2520, that has a J2 error code. We can't fix a service rep locally.


1. turn off XD125f
2. Turn on
3. within 4 seconds press, clear, auto, clear, auto. LED Should go blank,
if not try again
4. use copy quantity keys to enter 24, then push start
5. Again use copy quantity keys to enter 7, then push start
6. turn off
when you restart the cartridge count will be set to zero

I have done this twice and never replaced the drum cartridge.

Fault Code COF37


COF37 is a code for ATDC high black density failure. Several different things can cause this code & I assume it does not clear by turning the machine on & off.It may be a dirty sensor or may need a black developer change. Either way I would recommend contacting a tech as the process unit can be tricky to remove.
