Question about Sharp FO 5550 Plain Paper Laser Fax

1 Answer

Printed pages look terrible...

One day one(1), drum was replaced. On day eight (8) printed pages began printing poorly (dark, streaks). On day fifteen (15) replaced toner cartridge, but poorly printed pages continue. Since the pages began printing poorly after the drum was replaced, but before the toner cartridge was replaced, I figure the problem is with the drum replacement.

I'm more familiar with HP printers, but it sounds like a fuser is bad. The fuser effects print quality as well. If you've replaced the toner, as you have.

I just picked up a 4500n hp laserjet, and it was very dusty inside and out. So I cleaned it inside and out very thourougly. I plugged it in and print the configuration page, the plc, ps fonts, demo page 1...


Most likely the drum is failing. After printing pages remove the drum and see if it has streak on it to be sure (don't bother trying to clean it - if it has streaks the cleaning mechanism has failed)

Dark streaks


Dark streaks are an indication of "burned" or overheated ink. This will occur when the printer sets for a long period of time and nothing is printed. The problem will usually disappear after 50 pages or so, unless the printhead is damaged.

If the print remains dark, the printhead will need replaced.
(Very expensive)

(Dark print can also be caused by using Non-Xerox ink)

Black smudge streaks on rightside of printed/copied material


Can only be two things the drum or the fuser. More than likely drum they last about 4 toners i think.

Learn the art of getting a page to stop halfway threw printing, you want to stop the page after the drum has put a image on the paper but before paper has gone threw the fuser (hotbit).

Once you have mastered the position correctly by stopping the printing by opening the door and removing drum/toner cartridge, to reveal the paper that is printed but can be rubbed off, we will know if marks are coming from the drum (you will see them) or from the fuser, if print is fine.

Streaking


Hi there it will be either the drum unit for the color streaks you are getting or the fuser unit. Check the drum units for the streaks on them also check the fuser but the clue is when you have the streaks in different places. Most likely to be the drum units. You will need to replace.

Thanks J

Black streaks on printout page


It sounds like excess toner has built up in or around the imaging drum. I would *carefully* remove the toner and drum (can be messy) and use some canned air to clean the inside out. If you are still getting these streaks, it might be time to get a new drum (DR 400) as you are supposed to replace the drum every 6 to 8 times you change the toner cartridge.
