Got a problem with c452 that colour registration moves out when doing multi copies and printing....some examples attached.
We already changed drum drive section because of p31 code ...code gone but still colours shifts. But what is strange, 1st copy perfect and after 2nd copy or print colour shifting occours till end of job.upon starting new job whole cycle the same....( Happens with black copies and prints too )
parts changed : all image units , transfer unit ,fusingunit , lazerunit and tested hv board ,controller,io board,lazerunit relayboard...
Cleaned machine and transferbelt sensors,,,even swopped sensors around...
Any suggestions pleeeeease!!!!SKMBT_C25012041914490.pdf
