Printing too light


For understand the issue, little bit technical knowledge required: Take half test page, check how much dark image formed on paper, check on cartridge drum how much dark image created?..(half test page: while printing half of the page switch off the printer, take cartridge out as well as take half printed page)If half page print quality is good on paper: Fuser faulty(teflon sleeve)If half test page print not good & image on drum is OK: Fault with Transfer roller or its bios voltage contacts..If there is proper image on paper & image drum: Problem with laser scanner assembly..find the problem, then remedy is easy..

I think i have a fuser error. When I print something the right side of the paper is very light in color. If I print multiple pages, it gets lighter by every page.


Put paper in the manual feed tray. Print. When the page gets half way into the printer, open the cover. Remove the toner. Look down at the paper. Is the right side lighter than the left? If yes, replace the toner cartridge. I don't believe that a fuser could cause your problem.

Printer leaves black spots on paper


The black spots mean you either need a new imaging drum, transfer kit or fuser. You'll have to print some stuff and try to catch where the black marks are appearing. Try this method (it's called a Half-self test)

Load 2 -3 sheets of letter paper in tray one (manual feed) and remove paper from the rest of the trays.
From the information menu, request a demo page
The MOMENT the tail end of the paper disappears into the printer, open the right door. Open the front doors and release the levers for the imaging drum and the transfer drum. Carefully remove both pieces and examine your paper.



You should find the paper partway on the transfer belt but not in the fuser. If you see black marks here, start with the imaging drum. Open the shutter that covers the sea green shiny roller and look for marks on the drum (you'll see build up on the edges, that's normal, you should not see any scratches, pockmarks or toner on the center of the drum). If it looks clear, take a look at the transfer drum for marks or cuts on it's surface. (note: the transfer drum can be cleaned off with a dry lint free cloth, do not touch the shiny sea green roller of the image drum)

If everything looks good there, then likely the black marks are coming from the fuser. Let the printer sit, turned off for about half an hour to allow the fuser to cool. You can then remove the fuser and look at the rollers to see if there is any build up or damage there.

If you are not seeing any obvious issues with any of these parts, then start with the imaging drum. If you know that any of these parts have never been changed, then change them as they do have a limit to how many pages and how much time they can be used for.
