Streaks on faxes and copies but not on printed documents

When I print off documents, they look fine, but if I make photocopies or when I receive faxes, there are straight vertical lines running across the paper. Help!

check first if your printer can copy well. try to photocopy a document. and if it copies well, that means, its a problem on the part of the receiever, if it does not copy well, that means the scanner of your unit has a problem.

Received fax is unreadable or blurry
Please go through the checklist below to see if the suggested action(s) can resolve the issue.

* Make sure the copy function is working well.
* Print a Clean nozzle page from the Maintenance menu. If the printout has unexpected white or color horizontal streaks or missing portions, print the Clean nozzle page again. If you are still experiencing streaks or mission portions, you may need to replace your cartridge(s).
* The cartridges may need to be aligned.
* You may need to ask the sender to increase their fax quality.

Sent fax is unreadable or blurry.

1. If the receiving party indicates that the fax output is unreadable or blurry, you may want to try increasing the fax quality.
2. Check the scanner glass for excess amounts of smudges and/or fingerprints. If the scanner glass needs cleaning, moisten a clean, lint-free cloth and gently wipe the scanner glass. Make sure the scanner glass is dry before scanning the next document.

Constant blank streaks on both printed and photocopy items.

Hi Wooky,

The streaks are likely only present beside a bold character or heavy print section of the doccument content.
The print head assembly is likely carrying an obscure hair or piece of fluff back and forth which is acting like a paint brush.
The offending fibre is mos likely attached to the adge of the cartridge or print head carriage assembly. Also check the dervice station where the catridge docks when not printing as it can store fibres in the capping and wiping components especially if the printer is situated low to the ground where fibres tend to fly or you have fine haired pet like a cat, rabbit or toy dog.

Best way to clean is to trick the printer to unpark carriage (open top door to trigger carriage to present itself) then uplug power. Now you can move things at will to clean up with moist cotton buds (clean water is best).

Good luck
