Question about Panasonic KV S2025C Path-Through Scanner

Vertical Light Streaks on text documents, both single and duplex

When scanning text documents, there are streaks on the final copy that we have scanned and saved in a pdf file. The streaks do not show in the same location when running duplex copies, however the streaks appear to remain consistantly in the same place as if a roller was bad or a glass was smudged. Cleaning rollers and areas the document feeds through does not help.

Any suggestions? Is this a maitenance or a service agenda?

Thanks, Steve at Banner Lending

Clean the glass thoroughly using Isopropyl alcohol. Dont use solvents. Check if there is any scratch on the glass. Repeated scanning with stapler pins can scratch the glass. If it is scratched, you may need to chage it.

When using the auto feed, copies come out with black streaks down center of page


If you only get streaks when using the automatic document feeder, then in most cases it is dirt on the scanner glass. You do not state model but if you can also scan flat objects, trying copying a piece of paper that way. If that copy comes out fine, then you definitely have dirty glasss, if that copy has streaks you either have dirt on the scanner itself or a faulty scanner unit.

Hello I just figuered out this problem. When the paper is feed thru the ADF ( Automatic Document Feeder ) there is a plastic piece with a plastic film. Check to see if #1 that plastic film is clean and #2 That the Film is not bent and created a crease which is the line that shows when try to print or scan using the ADF. Hope this helps

Vertical streaks in photo scans


That problem is caused by dust or debris on the scanning "eye" itself. If you are confident in your skills, you can (UNPLUG FIRST) disassemble the scanner and use a microfiber cloth to clear anything on the light bar that scans your documents off.

Hope this was a little helpful,

There is something on your scanner glass. Clean the glass with glass cleaner. If this happens when using the automatic document feeder, open the top side cover where the paper feeds into. There is a narrow glass strip there. Clean that as well.

If this fails, the scanner head has a bad sector on the CCD and will need to be replaced. You will probably find that it will be cheaper to replace the printer entirely if that is the case.

Line in copies that go thru feeder


Hi,

Over time the automatic document feeder (ADF) will get dirty, occasionally causing vertical black streaks or lines in scans and copies .

Manual cleaning of the ADF might be necessary. Follow the procedure below to manually clean the ADF .

You will need the following materials:
  • Soft lint-free cloths
  • Glass cleaner
if you look carefully on the left side of ADF ( top feeder ) there is an assembly which u can lift , there wud be a set of rollers if u lift that part there would be a glass strip . u are suppose to clean that strip .
While holding up the inside of the ADF, clean the glass in the location of the vertical streak with one of the cotton swabs. Try cleaning the glass first with a dry cotton swab. If that does not correct the problem, then moisten the swab with glass cleaner .
If the vertical lines or streaks still appear, go through the above cleaning process again, this time cleaning the entire surface of the ADF scanner glass.
and after this try the following steps as well .
CAUTION: Use only glass cleaner. Avoid abrasives, acetone, benzene, and carbon tetrachloride, all of which can damage the scanner glass.
