Horizontal lines on doc feeder only

[MP C5502 Fan]

Ricoh MP C5502 with three horizontal lines in the middle of the page. This only appears when using the document feeder -- platen works fine. Appears on both scan and copy. Optics have a small amount of surface dust, but no obvious damage.

Is the slit glass dirty?

Re: Horizontal lines on doc feeder only

Its the slit glass, if it were the drum or hot roller the lines would be edge to edge.

Re: Horizontal lines on doc feeder only

Issue occurs only using ADF -- both scans and copies. No issue on printing or scans/copies using the platen glass.

Do you know what a slit glass is?

Of course the slit glass isn't dirty. You think I'd post it here if it was?

I know nothing about you. You are the one standing there. It's a good time to make some observations.

Well, I'm not completely brain dead... clearly I wouldn't waste everyone's time and energy if the problem were so obvious.

Re: Horizontal lines on doc feeder only

All digs aside, it is still the slit glass or the optics on an edge that is only in the path when scanner is moved back behind normal scan start position. Only other choice is if you have single pass doc feed and the CIS has the marks and what you are showing us is a two sided copy.

Re: Horizontal lines on doc feeder only

I personally have ran into this issue on multiple occasions, where the offending marks on the scanner glass were not visible to the eye. Removal of the scan glass and a good cleaning with ink remover always took care of it. If that is a second side duplexed original, the cis would be the culprit (previously mentioned in this thread).

Famous last words before possibility of inserting foot into mouthUNLESS they are printing onto paper that ALREADY has lines on it (I've seen that too).

Re: Horizontal lines on doc feeder only

You have something like spots of clear adhesive or ink on the slit glass. Regular cleaning with glass cleaner will not work. Use ink remover as mikadonovan said or what I have always used are alcohol prep pads.

The invention of the gel pen was a bad day for the common document feeder. Write great but ink dries too slow. Someone signs a paper, runs it thru feeder before ink dry and the streaks begin.

And unlike white out it is very hard to see.

Re: Horizontal lines on doc feeder only

i have over looked spots on the slit glass before. perhaps you have tried this already? only a suggestion. you have laid the document face up on the platen and traced the line over the slit? i have found a few using that method that i didn't see just looking at it. and even after having wiped it off several times. and i have moved my angle of view as sometimes overhead light hits it differently and then i spot it. but you have probably tried all of that already. im with everyone else sure sounds like the slit glass.
