How do i replace the image transfer belt on my bizhub c203? where is it located?

Have you tried the High Voltage board that supply the voltage to the print heads and ITB. could be the print head is fine biut not getting any power to fire the laser and write to the drum

PROBABLE CAUSES:

1. Detecting Plate not positioned properly.
Shape of the detecting plate has been modified. Install the modified Detecting Plate (p/n A02E 5033 01). Please refer to the attached procedure for
instructions on how to install the modified bracket.

Note :The following are the serial number cut-inswith themodified Detecting Plate installed:
bizhub C353 - A02E010005899 and onward
bizhub C203 - A02E012005777 and onward
bizhub C253 - A02E011005566 and onward
bizhub C353P - A02E013000060 and onward
magicolor 8650 - no cut-in available

2. Transfer Belt Retraction Sensor (PS31) mounting bracket (p/n A02E 1121 00) is fixed with a screw and it can be tilted while assembling. If the bracket is
tilted, the sensor cannot detect the Transfer Belt position properly. In order to avoid tilting the bracket, the shape of the bracket has been changed.The shape of the sensor actuator has also been changed because the actuator could touch the other parts.

PARTS
A02E 1121 00 -current Bracket
A02E 1121 11 - modified Bracket
A02E 1122 01 - current Actuator
A02E 1122 12 - modified Actuator

Notes :

a.When at the machine, please check the condition of Sensor Bracket and change the Sensor Bracket and Actuator if necessary.
b. Please refer to details in attachedBulletin Number 6252 (applies tobizhub C203/C253/C353).
3. Somepacking material was not removed froma new Transfer belt before installation. Ensure that allpacking material has been removed before the Transfer belt is installed.
4. Failure of the Transfer Belt Retraction clutch (CL7).

Check for wiring being pinched from bypass door and replace the failed parts.

Yes!! it is just a small fuse. It can be bought at www.partsnow.com or precision roller. SUPER cheep. then release the the belt and its on the left side under the cover by the spring held on the shaft

open right door (the door used to remove jam. there are 2 silver levers that have screws holding them down just under the fuser unit. remove the screws and that will release the belt. it wil slide out easily . then replace it. unfortuneatley you did not have to replace it unless it was dammaged... there is a small pico fuse in it that you can replace for like 2 dollars that will reset the counter... if you have more questions drop me a line

The p error codes you have are due to the test pattern being put on to the transfer belt to check the image density control
The first thig to do is to check and see the condition of the transfer belt and if it has reached life or looks bad replace it also on taking out the transfer belt directly where it goes in there is a cover slide the cover and clean out the idc sensors imgae density control sensors
Also there is firmware to correct the issue do this last the above will get rid of your issuesAlso add toner to all the units manually add the toner as well

Sir did you remove all of the tape from the transfer belt. when you installed it the the code has to do with new belt. Pull it out and check for any thing odd.
