I have one photocopier bizhub 501 and have error code 2801/03..Can you help me? thnx

Fusing main temperature low sensing.
clean TH1-Thermistor.

Power ON machine by pressing Utility Button.
and hold for 15 to 20 seconds.

Touch TROUBLERESET once appear.
now restart machine from main Power which is under Toner Door

The 501 code is not for bizhub 350 is for dialta 250/350/2510 and refer to fusing unit error.

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. ^^,

Power off the machine wait ten seconds then holding the down the clear/stop button power on the machine. should clear the code if the code comes back replace the fusing unit the hot part!

Code M2 means your photocopier machine require maintenance.In maintenance some old parts of your machine will be replaced with the new one and all this will be performed by technical services representative.

My Friend You must do general service in your photocopier and then you must program your machine.

You can download all manuals user manuals for your machine at kmbs.konicaminolta.us . However user manuals will NOT have C-codes in them for the customer.
I do not see a error code C-6xxx. If you would post the error I may be able to help you with the problem.
