Re: Constant blank streaks on both printed and photocopy...

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

It won't scan or photocopy.

This issue might occur if the scanner bulb is damaged. Please repair your printer in a service center.

Ricoh 1224c prints on left side only - Blank on right side

well if its just on the black then it might be the black drum see if it does the same on the color from copying and printing. If it does the same in color then its not the drums it may be the developers, but you wont know untill you test the color if it only happens in black and white its definitely a problem with the drum.

Lines rule across my print out paper at photocopying mode

Make sure you don't have a scratch on the glass of the scanner. If you have a mark, or scratch that matches the line ruled on your print, then there is your problem.

It;s also possible the scanner is jerking as it goes across the bed, which is causing the line. Is the line solid, dashed, bold, thin or just kinda there?

Photocopier prints red

You might be running low on black ink and it's not an item when you print from your computer because the settings you are calling for are different. The computer asks you if you want to print best, etc.

Sharp AM-900

It is either in the path of the scanning like the platen glass or if it is a MFP check the little glass strip on top of the glass thats where auto doc feeder scan from, or the imaging drum/toner is bad, or the transfer belt is bad or worn and there could always be a roller causing the marks, or the fuser itself can be bad. there are just too many things that can cause that. is it streaks with no print or is it printed then scrated like streaks?
