CANON iR ADV-C2230i - bright stripes

[Zela]

There are my light stripes when copying, and printing it is OK.
I have a suspicion scanner unit but I never found a similar problem.

What have you done so far? Did you clean optical unit? Copy from the glass is ok?

looks like transfer to me, but it would help to know what you have done thus far before we can recommend anything useful, otherwise it's just random stabs in the dark.

I am confused. You post a PG10 test print but say its OK when printing but not copying. Is this a copy of PG10 test page or the actual test print? Looks like something dragging on itb, deformed patch sensor holder or out of place. Its at the side...you lower it to remove itb. If posted sample is an actual COPY of PG10 and PRINT of PG10 is ok, then yes, a scanner issue. Clean it, and calibrate it(CCD adj with 28 lb 98 brightness paper and DF-WLVLs with same). If its on prints also, clean the laser windows for a start. How old are the drums,itb,transfer roll,etc)

I also undarstand that print is ok and posted pic is copy

You were right.
When cleaning the scanner I probably accidentally wiping cloth on the rail in the reader.
From the perspective of the mounted scanner could not see anything.
But when removing the scanner and seeing it from a different angle, visible oily smudge.
thank you
