This copier gets a 3/8 inch line on the trail edge of every 11 x 8.5" copy in the direction of the paper path. I cleaned the transfer roll, laser shield and optics. I increased the trail edge erase and it erases but the little tick mark stays. I move the image (registration) and the tick mark stays. If I copy in Letter-R I dont see it but letter, it happens every time. Any ideas?

Just a thought. Check to see if anyone has been leaning on the left front of the machine. Since I can't see your line, this is a simple test to see if the scanner is bent; lift the left front (almost enough to pick up the machine) and see if the line disappears. Reason: We had problems with shadows on prints on a 9935/45. It was the arm supporting the scanner, which was later fixed. I had the same problem on a 2020. Shadows to lines show up with this problem. Mirrors and scan glass cause full length fine lines.
Good luck

CQ
I agree w/ previous post. We see this all the time. Usually it copies fine from glass and prints but poor cq on front side when using DF.Comment

I agree with the previous posts as being a possibility. Just to rule out the improbable, are your outer fuser strippers clean of toner?NEVER ASSUME ANYTHINGComment

If an internal print (SP mode or meter sheet) is clean. The problem is definitely optics somewhere.Don't take that toner with me!Comment

I think you have to adjust the ADF. There are 2 screw holes on the right hinge of the ADF (where the ADF is connected to the main machine). One hole is bigger than the other. When you use the bigger hole you can adjust the ADF Position a bit.Comment

Could be internal to the laser unit.
You can also try stopping the copy before it fuses to see if the mark is coming from the drum or not.
Maybe the underside of the drum shutter is dirty and wiping off on the copy after it passes the drum.Don't take that toner with me!Comment

Even tho cleaning the picker claws on the Pcu didnt do anything, replacing them solved the problem. I think the trail edge of the paper was curling and flicking up against the claw and picking up the toner there.
Whew, that was a tough one. Fortunately, the room was air-conditioned so they coulndt see me sweat! I was like a duck, calm and cool on the outside, paddling like hell underneath!

Why didn't you make it jam half way through the fuser or before the fuser and check before and after copy quality?
That is our basic troubleshooting test.Comment

Not to be a total biach, but I'm sure that was part of the troubleshooting process, just not needed to say it...Jomama is a seasoned tech. Those of us who have been around know the basics are always done by certain techs but not always stated. Yeah I'm assuming but I think I am right in this case. And FearlessVK already suggested that.
Anyway the case is closed so what was the point of offering up new advice?
Got your back Jomama!!

I think we all run into extended repairs on occasion. Be it 3 minutes or 3 hours, it's still a fix. Hey, it's Friday. Time for a beer!Even tho cleaning the picker claws on the Pcu didnt do anything, replacing them solved the problem.

Lol Sorry Kopy, been a long day. Didn't mean that to sound mean and didn't see him mention that. Jomama has been helpful. I was just thinking if that was done wouldn't he have seen the area of the problem.Not to be a total biach, but I'm sure that was part of the troubleshooting process, just not needed to say it...Jomama is a seasoned tech.
