Bizhub 420 is showing me a C2801 code please help if u have an idea.

1102 is output tray lift motor did it hit something on the way down? 2801 replace the drum and developer

When was the last time the developer was replaced in the developer unit? If has been replaced then you might have a bad ATDC (Automatic Toner Density Control) sensor Located at the rear of the drum and below. (Remove drum to see, has a white cover on it attached to a control board, needs cleaning,2nd replace. If the developer was replaced when it was done was a vacuum cleaner used? IF so the static electricity from the vacuum clear destroyed the sensor, NEVER USE a VACUUM cleaner to remove the developer. Also when the developer was replaced, was counter cleared to tell the copier developer was replaced, the copier use the counters to determine certain voltages for certain assemblies, if not image problems and codes can appear. Finally was the F8 run after the developer was installed before any prints or copies made? If not buy new developer and start over, counter is to be cleared first, then developer replaced, then F8 run.

replace the developer and run the required F8, BUT FIRST MUST CLEAR THE COUNTER for developer before removing developer unit.

actually code c28xx have 7 variant. for example, c2801, c2802, c2803 (error 3,4,5,6) and c2804. if follow the code code c28xx is TCR output abnormality.
ok, first you clean T/S block, do servicing and cleaning all parts.
second, if still same, do toner auto supply.
third, trouble reset. off your machine first, press and hold utility/counter and on machine, until trouble reset appear. press it and off/on again. ^^,

Maximum density correction problem.Clean the AIDC sensor located under OPC drum.

sir i have a bizhub Minolta 500,the problem is that it shows the code c-2801 and out put trays are not working ,when i start the machine and code is shown and machine is not stared please help me its urgent case

In my experience you have to change the developer and the machine will be ok.Also there is a chance that you have to clean the two toner sensor that are located in the end of the toner bottle,sometimes there is the problem.please let me know.
