Hi,

The black marks normally comes from a worn fusing unit. in most printer nowadays, you buy a maintenance kit that comprises of roller, pickup rollers, fusing unit and drum. after changing those items mentioned above, you should correct the 3 black marks on your printouts.

As you said it looks like a roller marks, so just clean the roller first.

there is probably ink on the rollers. get some paper and just keep feeding it till the black marks stop. and RECYCLE the paper that you fed. DO NOT throw it out

Laser printers do not use Ink. The problem is most likely a defect on the drum, which in this model printer, is part of the toner cartridge. Replace the black toner cartridge with a known good one and test.

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.

Hi,
You don't say whether the mark is a dent/dinge in the paper or whether it is a dirty or inky mark. If it is one of the rollers pressing and making a dinge in the paper you need to check for flat spots on the rollers. Do check all the rollers as the problem may be caused by another roller not gripping properly or the feed rolls being twisted therefore the one where the dinge occurs is over compensating. You can get rid of small flat spots or shiny bits on the roller by GENTLY roughening the roller feed wheels with a fine emery board. This will also clean off any dirty marks on the roller. You can clean dirty marks off the rollers with a non-lint cloth/specialist wipe. (I use baby wipes). Make sure you get rid of all the dust, as this will cause more marks. Clean the platten glass, again with a glass wipe or windowlene to get rid of any marks there. It is also worth taking out the catridges and wiping the ink surfaces. I use kitchen roll and the a baby wipe. Do test the baby wipe first to make sure that it does not damage the printer. If it is possible without taking the printer to pieces wipe the cartridge feed bars. I use a oil based specialist wipe fro this. Another thing that could cause the symptom that you describe is a piece of debris/stuck paper in the feed path. So check that the path is completely clear. You would be amazed at the impact of even a tiny scrap of paper stuck can have.
If you printer has a clean cartridge utility, do that for both cartidges and run the alignment routine before using the printer again. Print a test page to check that you have got rid of all the marks.
Good Luck Please send me feedback so that I know that this fixed the problem.

1. Turn the printer off and open the access cover.
2. Look for any obstructions in the paper path and remove them if necessary. (It is possible to move the carrier assembly with the power off.)
3. Turn the printer on, load some paper, and press the Form Feed button. (On the X83, press the Select button.)
4. Watch the paper as it feeds through and try to determine where the jam is occurring.
5. Check to see if all the rollers are turning.
   
   If all the rollers are turning, there may be something in the feed path that you can't see. Go to step 6.
   If not, there is probably a feed motor or a gear problem and the printer may require service.
   
6. If the paper is jamming under the carrier assembly, you may be able to fix it using the manual feed slot.
7. Turn the printer off.
8. Take a #10 envelope and feed it through the left side of the manual feed slot until it comes right through the printer to the back of the exit rollers.
9. Move it up and down first, and then slowly move it over to the right side. If something is stuck under the black guide plate, this may work it loose.

On the ADF check the twink mark on glass scanning mirror

I've seen this before. Since the printer portion is working fine that points to the scanner mechanism as the culprit. There are two things I have seen cause this. 1) If the line is a perfect rectangle all the way to the edge of the page then the light bar itself is dying and there isn't much you can do to save the unit. Send it in for warranty repair if you have the option. 2) If the line is more like a skid mark like you mentioned, then the paper that is being scanned is not pressing up fully against the light bar. Not enough light is bouncing off the page and the scanner can't read it well. This can also be caused by a roller not feeding correctly and then bunching up the paper a little bit. I would check the rollers for wear or something being off center. This can sometimes be caused if the machine has ran a high volume or thick paper. I would really think the cause would be one of these two since you are getting the marks at odd intervals, if the intervals were regular it could *possibly* be the drum but as I stated before, with the print function working right, I doubt it.
