I have a mx-3100 that will self print fine but a plain old copy will come out with lines and distortions as though there is dirt on the spf glass or mirrors. Both of which are clean. All the usuals have been checked mechanically. I tried running a 66-10 to clear the memory but that didn't seem to make it go away. One thing I think might be correlated is the customer every time it would get stuck on a print job (vpn '>.> ) when you go to clear the job it pretty much gets stuck and takes an excessive amount of time to clear which they were shutting it down via the power switch instead of the power button up top. My thoughts are memory corruption, which I just happen to have a 2600 in the shop for scrap but dont think I can just swap the memory on one of these same family or not.

Re: Sharp Mx-3100 copies distorted
I'd be curious to see samples. =^..^=If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

First is a copy of the hdd report and second the 64 - 5 self print and a copy of it.Comment

Re: Sharp Mx-3100 copies distorted
Does this happen off glass and scanning.Looks like CCD to me.Comment

Re: Sharp Mx-3100 copies distorted
I wouldnt be surprised if the machine was kicked etc but as far as laser adjustment, no idea. Happens either through the spf or the flatbed. Optics inside the flatbed dont look like theyve been damaged etc.Comment

Re: Sharp Mx-3100 copies distorted
Is this machine set up to scan? You'd get the most information from a color scan, ledger size, off the glass.
If it's a CCD focus issue, the focus will be better at the leading edge, and worse (turning blue-green) towards the trailing edge.
If it's a mirror focus issue the image will be better at the front or rear of the machine then the opposite worse (a band in the feed direction), possibly with blue-green background.
I would check these things:
-Clean all mirrors and lenses with 95% alcohol. Oily residue can cause strange image quality issues.
-Rock each mirror to confirm that it's setting on three points of contact, and leaf springs pressing the mirrors against said points of contact.
-Check that the scan rails are clean, lightly lubricated, and the glides (small plastic buttons that the scanner coasts on) are still in place, not loose or falling out.
-Check that the scan cables aren't loose, or the light sources obviously askew.
-Check the reflector on light source #1 is not bent, possibly from pressing down hard on the glass copying books.
-Clean the CCD lens surface with 95% alcohol. If you can access the other side of the CCD lens clean that too, but do not disassemble the CCD.
-Reseat cables to the CCD, scanner control board, and controller board.
These things have resolve 90% of scanner quality issues. =^..^=If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.

Re: Sharp Mx-3100 copies distorted
I would try all the things blackcat has mentioned, if that don't work. If that does not work or you have already checked those things 1) CCD unit (easy swap) or 2) Scanner Control Board.Comment

Re: Sharp Mx-3100 copies distorted
Thanks for the info. I hadnt even thought of using ledger to get a broader perspective from the flatbed. I will be back there in Tuesday, will post follow up if there is a resolution. This one is a real pain, between the customer being on a vpn and the whole shutting it down randomly deal.Comment

Re: Sharp Mx-3100 copies distorted
Looking at your examples, the printout AND copy is skewed and the margins on trail edge is very wide. I would ensure that your K laser is aligned; all the color align from K. If black is jacked, the rest are whacked...lol, that just came to me.
ADF could also be skewed and a copy from platen would determine that.
The other thing I notice about your scanned examples is the issue does not go edge to edge, it is within the range of optics. Being that prints are good, the issue is most likely somewhere in the optics.
Run your shading and SIT chart setups in SIM 63 after you get the laser lined up. On this older model, I think it is SIM 61 for LSU alignment....
Failing to plan is planning to fail!!!Comment

Re: Sharp Mx-3100 copies distorted
That kind of struck me with a thought, might be dumb. I replaced the entire adf the other day. Old one had feeding issues. Is there a way that could have skewed the spf in such a way as to produce that? Part of me is second guessing that now whether or not I tested both spf copies and flatbed copies or not. Or if the difference between a mx-2600 and a mx-3100 is enough, if memory serves the part number was the same for both. *facedesk* I'm goin back to bed.Comment
