IRC 2620N Printouts with thin lines

[mkarip]

I have thin lines on all printouts, sometimes more sometimes less.
What could it be? Drum Motor? Laser?
lines occurs only in black, i have replace black drum, no luck
I am grateful for any help

Are you referring to the 3 V shapped marks on your sample? remove & inspect the ITB could have a small mark etc.

Thanks for Response Canon.Tech

the v marks are from me to see better the thin lines..TransferBelt replaced earlier..no luck
sometimes all good next time maybe 30 thin lines all over the prints.
Replaced parts with no luck: Black Drum-TransferBelt-Sec.Transfer-Belt Cleaning Blade

Other solutions welcome

Firmware level? Put in the newest firmware to start. I have seen fixing/feeder drawer open/close sensor(photo interrupt) cause noise to the dcon and create laser issues. Old bulletin about this. Change the photo interrupt. Post a grid test print,and separate test page 5 for each color. P print with a ram clear would be next. Sample orientation....LTR,LTRR,A4,A4R....???Put an arrow on samples to show lead edge/paper direction. Does it do it on just copies?Prints also? Need more info

You say the line only appears when printing black? or are you saying the line is black?

Could be the another drum leaving the line, as it’s very fine it may look like it’s black.

Does it happen on prints, copies or both?

lines occurs on both copy&prints, black or color no difference..only P-Print is always clean.

Weird?! By chance is that Magenta example run LTR direction or LTR-R ? and had you set it to use only the Magenta alone on that printout ?
