Konica C1070 error C2213 and C2214 on every print....HELP PLEASE

**alyweka** · 10-30-2023

Dear all friends, please help me solve this weird problem.
I have Konica C1070 that was working like a charm, electricity once shut down and get back suddenly so my machine stopped working
My technician found a burnout PRCB and Fusing Board and changed them and from here the problem starts
now when i power on the machine it starts normally then when sending any print job on any paper it gives me error C-2213 or C-2214 and the paper stacked before entering the fuser with no print at all
I did change:
PRCB
Drum Motor
Encoder Sensor (PS57) (PS56)
DCPS2
Drum Unit
Drum Encoder
even i get an old machine i have (Konica C1060L) and put the complete process unit (with 4 drums and 4 charge corona and 4 developer tank and the transfer unit) and same code errors C-2213 and C-2214
Also my technician changed the firmware for PRCB with updated one with no success
what could be for this problem because my technician told me he didn't face this problem before and he changed all of the manual said about solutions
someone told me maybe it is corruption between the firmware of the image processing board and the firmware of the PRCB that gives wrong speed for the drum
please help me friends

Have you tried replacing the Drum Drive Board? You didn't list it specifically but said later that your tech replaced everything the service manual suggested. Has your tech tested those components in the load check? You do have to take load checks with a grain of salt though, I know being in service mode the machines will ignore certain failure codes and still run the component in question.

To get to the printing point, it needs to make adjustments and approve their results.Auto Gamma Adj.
Color Registration Adj.

When these tests are performed, they generate an image on the transfer belt.

We need to know the result of these adjustments and, if negative, evaluate whether there is an image on the belt during execution, or try to print a test directly from test mode in service mode.

The relationship that the two errors have in common are PRCB, (which was replaced) and DCPS2, which deserves attention as it experienced an electrical problem. Find out which connector comes out of it to power the sensors and take the voltage measurement.
