    It is a Canon IR 2800. I did breakdown and purchase a service manual for it. I think that I got it done correctly. Thanks for the response.

What kind of copier is it? Is it a Canon? It sounds like it is, what model is it? There are diffent ways to get in to service mode. Basicly, the APVC put a charge on the drum to level it out, to off set the surface of the opc drum, to offset any ambent temputures the drum was exposed too. You can also run a sky shoot and then do your adjustment.

Error c2814

The proper value cannot be figured out within the specified time by the correction of the patch density correction /K. Or, the proper value of the developing DC output is 0 or lower.

Associated Parts:
• Printer control board
• Developing unit /K
• IDC sensor (IDCS)
• IDC shutter solenoid

Remove the black (K) Drum. behind and toward the front is a silver/chrome looking thin bar with a tine square that square is a sensor clean it or replace the drum (switch different color see if changes codes) or switch out sensor with a different one each drum has one when was the last developer was replaced for black getting close to a PM???

Toner NOT sticking to paper

"Cars & Trucks" is not the correct place to post your question for your Xerox XC1044 Copier. However, I can tell you that the heating element in your drum assembly is most likely defective. That is why the toner is not is not getting hot. You will have to replace your drum assembly to fix it.

HINT: on an older copier/printer like the XC1044, it is usually just as expensive to replace the drum assembly as it is to buy a new copier/printer. You should probably shop around before putting any money into it.

Correctable Ribbon not working. Even tried putting new one in

If the correction is lifting and being struck by the hammer the correction tape may be on wrong, the dull side must face the ribbon. The other easy possibility is that the ribbon is very old or non correctable. It should have a yellow or orange knob not red or blue.

Panel shows error code Cof24

(Automatic Image density Correction) basicly this sensor looks at the drum and determines thew drums ability to hold toner and image. The sensor could have toner spilled on it or the drum needs to be replaced or the senor has gone bad

Canon ImageRUNNER 300S - Replace Drum

All you have to do is have a phillips screwdriver and remove the screw that secures the drum to the copier. Before removing the screw you need to release the developer unit out of the way. Just perform the same procedure as if you were going to put new toner into the copier but you don't have to pull out the developer unit. Then just to left is the drum unit and at the top of it should be a black screw. It will be about an inch long. Then just pull out the drum and put in the new one after removing all the packing material. Be sure to not touch the round cylinder of the drum unit, that is the drum. Also, you may want to practice put in the old drum several times before putting in the new drum until you're sure you can put in the new one without damaging it. There is another thing that should be done but that is a technician thing and is probalbly beyound what you am7y want to deal with. It doesn't really ahve to be done but a tech should do if he replaces the drum for you. It most likely would not affect copy quality and will not hurt the drum if not done. Good Luck and be careful.
