Unexplained lines on scans

[blackcat4866]

If your customer does not let the ink dry before scanning documents this exact problem can happen many times a day. The customer needs to understand that they are responsible for cleaning the slit glass when necessary. It's not difficult.

Who knows? Maybe they'll learn to let the ink dry? =^..^=

When you'd like to include a quote from a specific post, at the bottom of that post you'll find a button called "Reply With Quote". Click that, and a Reply window will open with the desired text already in the window. You can edit that text, or add after it, but you must leave unaltered the prefix and suffix (before and after) the quoted test.

And I'm not smokin' nothin'. =^..^=

Every time they call, clean the slit in front of the client, scan... "see it was just dirty"... next comes the billing part... should be a quick to learn lesson

Play with U068. I set one to -30 and haven't had a call in a week (-15 wasn't enough). You might have to adjust lead edge U071. Normally, 3140s don't let you access U068, so unless you have the super-secret code, you'll have to drag your tech rep over to put it in.

U411 might fix this too, but I don't like automatic adjustments, and I don't have the paper to adjust with.

This is correct on the fs1128 simulation 068 is the fix -30 but on the 3140 you must order a special chart to use when adjusting the dp.

Re: Unexplained lines on scans

I had too travel over 60 miles cause a Copier was had lines, We called them and ask "Did you clean the slit glass?" They said "yes and it happens when it prints" I got there there was white out on the slit glass and the line they printed was a scan job with a line in it. Sigh. That was Easy money there!

Re: Unexplained lines on scans

You may have already tried this but take the scanner off full color. One of our techs had this happen and that's what he did. I know that doesn't really fix the problem but if they don't scan in color they'll never know.

Re: Unexplained lines on scans

I had the same issue with many of 1128 copiers. Sometimes but not often on a 3140.
Cleaned the slitt glass, mirror, lamp etc.. and after a few day problem came back.
I change to B/W but some clients need to scan in color...
I ordered adjustment chart 302FZ56990 for the scanner and chart 303LJ57010 for the DP.
I'll post what the result is on an FS-1128 copier as soon as i have this issue by a client!

Re: Unexplained lines on scans

This problem is such a pain! I've got a few 3140's that need to scan color. I have the "super code" to adjust u068 on the 3140 but it keeps randomly making color lines.

Re: Unexplained lines on scans

I have attached a QA report on this issue as it affects alot of models.

Re: Unexplained lines on scans

Dust and/or particles may enter between the DP scanning slit glass and the original and appear as vertical
color streaks on the image when read by CCD sensor. By applying the new Sheet, the dust and/or particles
may be prevented from attaching on he original.

So the implication here is that the lines are caused by cool multicolored dirt sneaking between the slit glass and top cover, then dropping on light source #1? Or the cool multicolored dirt is being transported to the slit glass by the original? Does the mylar actually work? It seemed to help on the Falcon III and Saturn.

Re: Unexplained lines on scans

So far we have 2 machines with it. One of them was a 2026c mfp. We already repalced the scan unit and by this time the customer was a pita so we did it as a preventative measure. We had another one on the 3640 mfp. We placed it on there and so far have not heard anything. We do have a few 1135 mfp out there that people complain of the line or lines on copies or scans. By the time we get there the lines are gone so we cant determine if it was debris on the glass or a result of this issue.

Re: Unexplained lines on scans

I tried adjusting U068 to both +11 as recommended in the service bulletin and to +15, the max allowed. None of these worked...
From what I understand the "slit glass" was revised (pn: 303LJ02280 and 3LJ02280), according to bulletin C331-2H9-0035.
Sooo, I guess I'm just going to have to wait for the revised parts to come in...
Will update afterwards

Re: Unexplained lines on scans

Does this model have correction for lines on slit glass? Some models you can change thickness of lines it eliminates.

Sorry for not specifying - It's a FS-3640MFP. I was really hoping the FW update and the U068 correction would have corrected it. Looks like I'm in for quite a job, as these models don't allow for easy changing of the slit glass. I guess I could have turned color scanning off but this would negate that functionality in the future for the customer. Better to fix the base problem.
