MX 3070 diagonal lines

[Hansen88]

Hello, this machine is producing diagonal lines. The machine has under 200k on it. All supplies are up to date. the mag roller looks normal and the developer is not running low on mix. On the self prints I printed out it does not seem to be doing this. Anyone know anything about this trouble? The sample copy was from off the glass. When I ran original through doc feeder it did the same. I drew lines in some areas where the trouble is happening in case the scan is not good.Hansen Assoc_20221025_141303.pdfP.S. it seems mainly to do it in auto exposure. If I put it in text or photo it looks ok,even similar exposure levels. But in auto mode I get the lines

Re: MX 3070 diagonal lines

A little unclear on your troubleshooting.. You mention supplies and developer but then say it's only when using the glass? So 100% sure it's optics? 64-1 and 64-5 look good?

I just double checked and it is only doing it in the glass or doc feeder and it only does it on the black side of the test sheet. the color side looks fine.

I hate to ask, but I am sure you cleaned the scanner glass and the ccd lens? Have tried sim 63-2, 63-4 and sim 63-5? All scanner adjustments.

So if you copy a two sided original through the ADF is only one side looking like this? I ask because copying/scanning a two sided original thru the ADF will use two different CCD units.

I got problem solved. I was trying adjustments in system settings, image quality adj- copy image quality. The sharpness setting has 3 settings. From factory it is set on no2. I set it to number 1 which is less sharp and the copy looks fine now. None of the line problem and the sharpness level and all other aspects of the quality are looking good now. Thanks for the suggestions and replies.

I posted what fixed the problem but I did try your suggestion before I found what fixed it. Just letting you know it did problem with both ccd units.

Don't laugh but I was fighting a screen door effect for over a week. After tearing out all of the hair off of my head..IT WAS THE PAPER. Staples paper when you looked at it had the screen door effect in it. Good God. I felt like a fool.
