When you use the flatbed the copy is perfect because the ccd sensor is under the glass cover and obviously is free form dust/ dirt.
On the other hand if you use the feeder the ccd sensor is located in between the roller assembly (not sure exactly for this model).
This means that the page is scanned by the ccd in the feeder, any dirt on the ccd will appear as a black line. I assume that you are feeding papers from the side and not from the top that is why you get a horizontal line.
A quick test to see if the ccd sensor is dirty is to feed the paper from the top side to the feeder. If you get a vertical line it is a proof that your ccd sensor needs to be cleaned.
The worst case is that the sensor in the feeder assembly has a tiny spot that is damaged and it is causing the black line.
So , first try the test, then open the feeder assembly, locate the ccd and clean it. Hope that this helps.
Hi, When the paper is fed through Automatic Document Feeder
(ADF) it is scanned before copy or fax. The scanner is fixed type and is
located just below the ADF. The
lines are due to dirty scanner mirror. The printer/ scanner design is
based Sheet-Fed Scanner. Open/Lift the Control Panel (scanner top )(by
pulling it up from front - the area from where the paper to scan comes
out). Look out for the horizontal
mirror and use a soft, damp, lint-free cloth to gently clean the
scanner mirror, rollers etc. and enjoy clear scanning and copying! For example see the below picture: -
for any tron pieces of paper dirt etc.DONT USE PAPER, CHEMICALS OR ANY ABRASIVE
CLOTH as it may damage the parts.
Hope it helps! Good Luck! Thanks for using Fixya! CreativeTECH
Hello, when you open the copier platen cover, left of the copy glass, there is small narrow glass, which is used when you make copies from ADF. Over that glass is plastic protective sheet. Remove it and clean, also clean the glass. Use glass detergent and after cleaning dry it!
This black line sounds like it is definately coming from the ADF scanner glass. This is the thinner strip of glass that is located just to the left of the large original glass. You can verify this by making a copy from the large glass instead of using the feeder on top. If the copy comes out clean then it is definately the scanner glass. Just clean the glass well with glass cleaner and a soft cloth. This glass is only used when copying/scanning using the top automatic feeder
Good Luck and Thank You for using Fixya.
If you lift the top of the unit so that you can see the scanner glass and clean the surface on the left side and the very end of the scanner you should be ok. The sheet feeder runs the pages through the feeder and down to the glass at the end then back to the feeder and out to the stack of pages. If you try to scan anything with wet ink, highlighter, marker, etc some may come off on the glass and cause the lines to appear. Just use windows on a paper towel, not sprayed on the unit.
I hope this helps, if so please rate our solution.
If the problem only occurs when using the document feeder, the problem is not usually caused by the drum. When using the document feeder, try to notice where the scanner (the light assembly under your scan glass)stops just before the paper is being fed. Some multifunction machines have a small piece of glass that is separate from the large scan glass and the scanner assembly stays parked underneith it as the original is being fed over it. Most likely there is something on the glass where the scanner parks as originals are being fed thru the feeder. When putting your original on the large scan glass to copy, the mark on the glass will only show as a spot, but will show as a vertical line thru the whole copy when using the feeder.
