Black streaks on scanned copy - Lexmark X4270 All-In-One InkJet Printer

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.

Hi

Open your scanner lid and make sure their is no dirty marks sitting on your scanner glass. Also does this happen on the scanner glass or when using the ADF? If its on the ADF its most likely that the glass is dirty and needs to be cleaned.

Hello James,

Please click Vertical Bands Lines or Streaks in Copies Faxes or Scans to access the troubleshooting steps that should resolve the issue.

Let me see if I got this right.

The received fax is clean but when you send one out it has a black streak on it.
Cool! So far so good.
Makes sense because for sending, the fax scans the original document and parts of the scanning area could be dirty and so on. Therefore a black streak may appear.
The same black streak would also appear when you make a copy, because the original document must also be scanned.
Logical!

However for receiving faxes, the machine uses the internal memory and the print engine only, and the same applies to printing the transaction report, which comes from inside via the print engine.
The scanner has no rol in either situation.

Now I'm lost!

1 or 2 LEDs are burned out in the scanner unit.

Hello sir; Either drum cleaning blade or drum cartridge needto replace.

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.

If this is only happening with copies and not straight prints, it is possible that the problem is with the scanning unit. Use the soft cloth to clean the scanner area to the left side of the machine where pages are scanned when run through the page feeder. A spec of dust or other debris in this area will appear as a streak along the length of the page.

If it occurs on all prints, You may need to replace the drum or clean the fuser unit.

Does this streaking problem occur when printing (not copying)? If it does then you are probably looking at a consumable issue. Alot of times black streaking is caused by a defective or spent drum. Is your drum new? There is also a blue piece on the drum unit used to clean the corona wire that cleans the drum. Have you tried moving it back and forth several times?

If the problem only happens when copying and the streaks are as bad as you make them out to be then you problem have a bad CIS unit (scans your originals for faxing or copying)

It is because coping is not the best way to get a perfect copy on the printer, Try scanning with computer using black and white photo it will come out much better if you are doing a pic. then use color picture.
