Doing color mismatch fail

[Peter Sim]

Hi all
Need help.
Canon iR Adv C5035.
Printing color is double image but B/w was ok.
Attach here with PG6 and PG10 sample :
Doing the Auto color mismatch was problem ,it show "Auto color mismatch was stopped,start correction again,if error code continue to occur,
contact your service representative."

Already change Registration sensor and SL1 unit and reseat all 4 drum unit and developer unit,but the problem still same.

i also follow this links to rectify the problem but still the same:IR adv C5051i Color Registration Problem

Hope someone can shed some light on it.
Thank you in advance.

Check your patch read sensor shutter it is likely broken and the sensor cant read the patches on the itb belt

I had that on a C2225 and had to clean the patch sensors

What 20 year vet said, shutter, also have had problem, there is a bulletin on this. Part that breaks is about 10 bucks from PR.

had same problem in a remote gold mine. the dust there was so fine and abrasive that I had to clean the shutter rail and the solenoid every visit because the shutter would stick in various places....

looking at your examples .. i suspect its the CK laser unit. you can test this out by swapping the 2 laser units around and see if theres a change in the pg10 test. or you can grab a laser unit from a different machine and swap it with the CK laser.

Already swap the laser unit,but the problem persist .Will try to look into the registration sensor again and the shutter

when you swapped the lasers around did the problem moved to from black and cyan to magenta and yellow if you do a PG10 test page ?

Before i swap the laser ,the PG 10 is like this.
