Unexplained lines on scans

[Keymaster]

Hi

I hope someone can give me a solution: I have a FS-3140 (About 1 year old) and a FS-1128 (Installed today out of the box). When scanning through the DP there are unexplained lines through the copy on the FS-3140 a single yellow line and on the FS-1128 two blue lines. Here is the problem: This only happens when you scan something through the DP, when you make a copy through the DP there are no lines. both machines are configured for network scanning.

[Keymaster]

here is an example of a document

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 may sound silly, but I would try and scan from the platen and see if the line is there. I would also try and scan to a USB and see if the line is there. It could be something on the glass or mirror that is picked up when scanning in color but not there when printing in B/W (kind of like yellow highliter that gets copied in color but not there in B/W).

Agreed. It's usually the glass. =^..^=

hi, just to be picky the FS-1128 is B/W only, so lines cant be blue? Ok out of box check that none of the tape/gum that covers the scanner release yellow slider is on the slit glass and clean the glass anyway.
you can use the print with the lines on as a guide to where the offending spec is. do that for both printers.
hope this helps.

I beg to differ, madas. It's a b&w only printer, but a color scanner, and Keymaster is referring to scans.

I would remove the slit glass and lay it on some white paper. It's a lot easier to see the contaminants. I took these shots for an absentee enduser, that said that it could not possibly be the slit glass. She had wiped it. Unfortunately, there is a difference between wiping and cleaning.

oooppss you are quite right blackcat!! I am guilty as charged on this one. LOL
I saw the word copy and thought when Keymaster mentioned scan i assumed the copy was from the scan, "if that makes sense"

Look at this SB alwso for the 3140
U68 is in the new firmware for the 3040-3140

[monstott2010]

looks like dirty slit glass

[Keymaster]

Hi Guys.

Thanks for all the help so far. I will go to the Client today and see what I can do. Will keep you posted
Thanx again for the help

[tech07]

I fixed one recently by setting scan default to B/W instead of color..Haven't heard back in a month. This customer has my cell number and would have called by now

[Keymaster]

Hi thanx for everyones help. I cleaned the slit glass and it seems that, that was the problem.

[majorjim]

I am fighting this same issue with a customer colored lines when scanning with document feeder. except twice I hace cleaned the DP glass it has gone away. Then the next day customer calls back and the lines are in a different spot. If you lay paper on glass all is fine.

[chad.morris]

clean the slit glass

[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? =^..^=

Ha Ha what you smokin Blackcat? Ha Ha ha

How do you get the speech bubble a round text?

[blackcat4866]

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'. =^..^=

[hekotez]

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 :D

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.

[Dr.silver]

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!

[copygirl]

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.

[brecht2]

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!

[cmpelser]

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.

[eholyst]

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

[blackcat4866]

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.

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.

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

[Venom]

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.

[BHRLC]

Well it seems 3LJ02280 didn't come in for some reason, boss says it was just duplicate?
I misread the service bulletin - they didn't revise the slit glass, the service part is just a "sheet" of
thin plastic that you place ON the left side of the slit glass. Interesting. Hope it works.

[BHRLC]

So nothing worked...
I installed the Bulletin "fix" sheet piece - same issue of multiple vertical streaks
The only thing that even came close to remedying was setting U068 to -3, the streaks
are just less on that setting. Tried the "line correction" setting as well - no change.
It seems "Color Selection" setting in Function menu is missing?
I tried changing "Auto Color" correction to 1, no change as well.

Fixed - Coworker spotted some fine goop on the slit glass.
Kicking myself in the rear now.

Always, Always, Always the first thing to check for lines is the slit glass. I like to use alcohol wipes as they will remove small ink spots that are hard to see.

[Zackuth]

I always tell my customers to rub the slit glass with their thumb a few times, then use alcohol. Sometimes the goo gets a bit stubborn about removal.

[BHRLC]

Didn't think about getting alcohol wipes - will stock up now. AND rub the glass with my finger.
I cleaned the slit glass with "super blue" before, I'm still asking myself how it didn't remove it when
coworker used just a dry paper towel.
Thank you, guys
