IRA6055 Line on prints

[Brian8506]

See attached. Happens on prints and copies. I changed the primary corona, ETB assembly, ETB cleaning assembly. I swapped with another machine the entire drum carriage with the drum in itTest.pdf, the pre transfer corona, and the dv unit. Also cleaned the laser and the slit glass above the drum. Stopped copier with print on etb belt and line is there. What bothers me is that it's edge to edge even thru the void area. Trying to attach with no luck. Test pdf is in paragraph

I would suggest you change the laser unit coz for your pdf even the test print shows the line.

Print internal test page on ledger size paper from both the bypass and other tray and see the result. Is the line perfectly straight. From the pdf you posted it's hard to tell, meaning is it coming from laser, board or some other means.

Re: IRA6055 Line on prints

Is the line appearing on the same position all the time or is at random places ?, and is it only 1 line or more. The Ledger prints should say something about that, i would think. Run a few of the ledger prints, about 8 or so, not just 1. New year fun.

One line. Same place all the time. If I can get ledger paper. I will test it but I could probably get the same results from legal. Law office and they don't use ledger. Probably won't get to test until Tuesday.

You said the line was on the etb belt. Did you replace the etb belt cleaning blade ?. The lsu unlikely would not repeat the line on the exact position all the time. Take the cleaning blade from the other machine and swap it and see. I think the problem maybe mechanical.
The fuser and the rest would all have to be ruled out if the line is showing on the etb belt. Also check the contacts of the etb belt.

Line is on the page when I stop it with copy on the belt. Entire ETB assembly and ETB cleaning assembly replaced including blade. Everything mechanical that I can think of has been swapped or replaced. I can adjust quality and line will fade away but then copies are too light.

Wow. Mystery. Just thought of something. If you can, put a piece of paper of some kind of tape about halfway on hte laser glass . Then, in theory , you should only get print on half of the page, and the line should only be halfway if it is the lase writing that line, which I doubt it is. But anything is possible. Let us know when you solve it.
Is that line solid and straight, like a normal print. Take a loupe and compare it with a normal print. Also, try a print from a usb stick, pdf file..

When the going gets tough, the tough gets going......

Re: IRA6055 Line on prints

If the half the laser is blocked, then the laser cannot write to the drum as there will be no charged on that part of the drum, so the line should not appear there. Am I correct in that assessment.

Re: IRA6055 Line on prints

I blocked off half the slit glass with black tape and got black. Plan on being there today hopefully. Will try blocking with paper. Didn't think to do that

Re: IRA6055 Line on prints

Piece of fluff in laser slit glass area? Pull out glass, process(drum) unit, dev...blow out the area of light path gently. I've had a line from this a few times..

I checked that but I plan on checking it again because you never know

Nice call Canuck! I blew out the light path from the slit glass down to the drum. I also pulled the laser again and cleaned the mirror inside with a glass cleaner because I thought I could see spots that hadn't come off when I dry wiped it. Line gone. Going to monitor it so I don't get disappointed. Thanks Canuck for your help. Thanks also Subaro!
