Printer output has shadows, blurring, streaks, lines, poor color

you have to clean the lsu. laser unit. you will see there is a lot of dust on the bottom mirror inside. it is a big job. advice that you must be tecnical.

If your printouts are streaked or faded, missing black or other colors, have blurred or fuzzy text, or ink streaks or smears, or show other problems, please refer to the link below for troubleshooting steps for print quality issues.

if logo preprinted may not take heat if everything repeats check fuser

you need to run the nozzle deep cleaning utility, nozzle check and alignment procedure under the printer properties maintenance tab.
Please rate this solution. Thanks.

Defective main motor
• Image transfer belt out of position
• Belt mark blurred or absent

Right from the service manual
My best guess is belt mark blurred or missing
or image belt out of position

Quite possible something happened to the printheads.....especially the Magenta one. Might have been 'bumped' out of alignment. They might just need to be wiped clean with a toner cloth. They are usually right above the toner cartridges. Have you tried a color alignment adjustment in Config mode?

Hi, this is failed convergence and it is due to a faulty convergence board chip set. simply replacing the convergence board in this set Will fix your issues.

It might be your printer catridge problem. Try changing it and giving it a nozzle clean.

If you are getting the same problem with both TV monitors it could then be assumed it's an input problem to the TV monitor. If you are using a digital output from your receiver it could be the cabling. If you are using an analog output from your receiver it is probably coming from the receiver.
Digital video processing does have issues with darker scenes.
Can you try another video source seperate from the receiver like a DVD or better yet an analog VHS, if you still have one. Good luck and let me know.

That was the Solution that the ink cartridge required a replacement
