Question about Dell 3100cn Laser Printer

Big black marks down the center of every sheet?

Hi everyone:

Every sheet I print has a big black mark running down the center--straight lines, almost like a bar code. It seems to be getting worse and worse and I have no idea how to fix it.

I recently replaced the black toner cartridge, but I don't know how or why this would suddenly happen. Thanks for any help you can offer!

Why do I have white / faded print when printing black? It also has problems printing straight lines - sometimes jagged sometimes just faded.


I do not know for sure but it sounds like the paper is not griped properly, this would cause the jagged lines. I would try another ink cart when the loose paper problem is resolved. I hope this helps.

I have a Minolta CS Pro EP 1031 Printer that makes streak marks


Drum cleaning blade has gone bad. Especially true if the streaks seem to get progressively worse as you run multiple copies. In other words run 10 copies. If the last one out is worse than the first one out it is the drum cleaning blade. Cheap part...around $25

When printing the sheet of paper has 3 dots on the


Yes this could be the drum.

You could remove the drum and carefully look for the pattern of dots etc that you are getting on the page but on the drum surface.

I would suggest replacing the drum 1st and retrying.

If the black lines are just down one edge then the fuser could be to blame for the black marks but without being able to see the page i cant tell. The drum is certainly my 1st suspect and is easy for you to try.

Calibration runs fine. But won't print anything else!


Here are the things you will be asked to try if you call support. They may fix the problems as well. Taking the printhead out and putting it back in is the big helper.

Remove the black and color ink cartridges.
Right above where the black ink cartridge was, in the top left hand corner of the printhead, push up towards the ceiling and you should be able to push a button that releases the printhead.
Place the printhead right back into the printer and push straight back on the back wall.
You should hear a loud snap.
Replace the ink cartridges which should snap as well.
Close the printer.
After about a minute or so the printer will ask you to do a calibration.
Insert a paper and press start.
Scan the calibration sheet.
After that, in the menu, do a printhead clean.
(If this is a 5100, do it in the home center ->? in the top right ->Maintainence ->Clean Printhead.)
Do one basic and one deep.
Print a demo sheet to see if anything has changed.
If the picture looks better, continue to do cleans.
In the event that it does not, the printhead will need to be replaced and since the printer is still under warranty, Kodak specialists will try to overnight you a printhead.
The whole process is short and free.
The number for Kodak AiO Support is 1 800 421 6699.

Printing problem with Pixma MP500


It sounds like the black tank/printhead is leaking. If it is, it'll be empty soon. New tank will solve that problem.

A faded line prints across the page


The imaging bar has speck of dust on it.
Turn printer OFF.
Open the printer. Pull out the transfer roller. Should have a big green handle. Do not touch the roller.
Look inside for a shiny rectangular block about 5inches x 0.5 inch.
This is the imaging bar. Using a lint free cloth with no chemical and no water, gently wipe this bar to remove any specks of dust/paper specks.
Put roller back.
Close the printer.
Turn printer ON.
Problem fixed.
