Black horizontal lines across pages

Hello,
I have a user that when printing or making copies for instance, gets about 5-6 black horizontal lines across all pages spaced a few inches apart.  Any idea what can cause this or what I can do? Thanks.

If they are the same distance apart every time then suspect the problem to be caused by the components in this order First the drum that is in the print or xerographic module, the charge and cleaning roller are located in that module also. So I suspect that first.its .Located above and to the right of the toner cartridge. Secondly it could be the roller on the toner cartridge, that would occur probably every 1 1/2 to 2 inches apart, the drum would cause the defect about every 3 inches. It less likely could be coming from the fuser, and if the fuser was causing that you should also have a lot of jams. There is also a transfer roller on the right hand door that could be causing it, but that would be exceptionally rare.
If the lines are random and have no consistant spacing, I would suspect the power supply then the laser.

Horizontal line on printed page


When you use the flatbed the copy is perfect because the ccd sensor is under the glass cover and obviously is free form dust/ dirt.
On the other hand if you use the feeder the ccd sensor is located in between the roller assembly (not sure exactly for this model).
This means that the page is scanned by the ccd in the feeder, any dirt on the ccd will appear as a black line. I assume that you are feeding papers from the side and not from the top that is why you get a horizontal line.

A quick test to see if the ccd sensor is dirty is to feed the paper from the top side to the feeder. If you get a vertical line it is a proof that your ccd sensor needs to be cleaned.
The worst case is that the sensor in the feeder assembly has a tiny spot that is damaged and it is causing the black line.
So , first try the test, then open the feeder assembly, locate the ccd and clean it. Hope that this helps.

I have a grey/black line all the way down the right hand side of the page


Run a half test.
Put paper in the manual feed tray.
Print something, anything
When the paper is 1/2 way into the printer, open the cover.
Pull out the toner cartridge. Look down at the paper.
Does it have a black line on the right side?
If yes, replace the cartridge. If no, replace the fuser.

Hp laserjet 4 plus - keep getting a horizontal black line


yes you have to catch printer making the line and then as a page is being printed you need to open door to stop paper after green cylinder(drum) as it is entering fuser, then you need to remove paper from printer without pulling through the fuser, if you see the line then rub your finger across line up and down page, if it smears at all then its the cartridge if not then the fuser

BLACK LINE ACROSS THE COPY CANON IMAGE 2200


Most likely your drum unit is worn out. If it reaches the yield of 50k or more, it starts to develop grooves in the drum and toner gets stuck in the groove and is applied to your pages. If you have a service company, they can change it for you. We sell the drum for $220.
