How do I eliminate the solid black line on right side of paper when making a copy.This only happens in copy mode.When I print from the computer,it's fine.

Black lines on copy come from toner cartridge, or drum unit, or fuser unit which is in the back. check drum and see if you can see line, back of machine with flash light you may be able to see line on fuser roller. Be carefull Fuser is hot.
A copy that is good and then starts to get lines usually the drum unit...

hi there...

if there was a lines bands on the paper trace. try doing a print cleaning on the unit..

Yourprinter ink has spiltonto the main ICU and needs to cleaned thoroughly. This is a job for a technician. The ink is all over the roller. It will only get worse. It now needs a techy to cleanproperly.

This sounds as if you have some ink/contamination on the small scaning glass that sits to either the left or right of the main glass on the copier.(Depending on the model/make)As your original is scanned over this thin piece of glass the scanning device will see any spots and this will result in a black line down the page.Please clean the glass with a soft rag.

Unfortunately, your C3180 printer needs some repairs done to it or you . A section of the printing arm that does the printing is faulty. This happened to me and apart from replacing the arm (at considerable cost) I purchased a new printer at a much cheaper cost. You can use your faulty printer for printing from the computer but not for copying or scanning. MG

You may also want to check if the ADF is dirty or contaminated with dust or hair. Here's a link with some information about how to clean the scanner:

It seems there is a possibility of a problem with the printer itself, or perhaps the cartridge. You should first self-test the printer. Since we are unsure where the problem exists, we must do eliminative troubleshooting to rule out parts of the printing system. The self-test allows us to rule out software and the cable by testing the hardware by itself. Please note that this is not a "fix," but rather a diagnostic test to determine if your hardware is at fault.

Please begin by disconnecting the power supply from the wall (not the back of the printer) for at least "30 seconds." Then plug the printer back in.

Next, try this printer self-test by following the steps given below:

1. Make sure the printer is in “Copy Mode.”
2. Press the “Menu” button once.
3. The screen will display “Copy Menu: Copies”.
4. Press the left arrow button once. The screen will display “Copy Menu: Tools”.
5. Press the check button once. The screen with read “Tools: Maintenance”.
6. Press the check button once. The screen with read “Maintenance: Ink Levels”.
7. Press the right arrow button until the screen reads “Maintenance: Print Test Page”.
8. Press the check button once. This will start the Self-Test. Once the page has printed, the printer will stop. The test is not continuous.

The self-test should at least print out a set of either a solid black or solid color bars, if not both (if you have a printer with both color and black installed simultaneously). Should this test fail, please try it again without cartridges installed. If the self-test still fails to take paper in and make sounds like the carrier is moving across the paper, this is a hardware issue, and the printer will require service. If the self-test completes without any cartridges installed, run the self-test again with only a color cartridge installed (If you have both black and color cartridges, after this test, run the test again with just the black cartridge installed). If you find that either cartridge causes the self-test to fail, please let us know.

If the self-test prints, but has lines or smudges or other print quality issues, please let us know. This includes any print quality issues - we need to know if the problems you have with your black or color are based in the printer, or communications with your computer, or the computer's software.

If the self-test prints your test bar(s) clearly, the printer hardware is not at fault.

Most of the Lexmark printers (including the Z- and X- series) pull the paper down on one side slightly faster than the other. The printer hardware should even this out when printing. You should also ensure the paper meets the automatic feeder requirements of the printer.

If printing is skewed, feeding multiple pages or jamming, please follow these instructions (use a regular letter size paper to test after doing the steps given below):

Please check to ensure there is nothing obstructing the paper feed mechanism down inside the printer where it is not easily seen. If there is nothing obvious, unplug the printer and remove the paper. Open the front cover and look above the steel rod. You should see a conveyor belt with rubber teeth on it, like a fan belt. Take the bottom part of that belt and move it gently to the left. The cartridges should come out with it. Make sure the cartridges can move fully from one side of the printer to the other. Check also the output rollers on the bottom of the printer for any blockage. If it is jamming under the carrier assembly, you may be able to fix it using the manual feed slot. Turn the printer off. Next take a #10 envelope and feed it through the left side of the paper feed slot (The manual paper feed slot is preferred, but the automatic feed will do if there is no manual paper feed for this printer) until it comes completely through the printer to the back of the exit rollers. Move it up and down and slowly move it over to the right side. If something is stuck under the black guide plate this may work it loose or you may have to feed the envelope through the front rollers and push your way backward (please be careful here).

Next, take a damp warm cloth and clean the rubber rollers in the automatic sheet feeder. Dust may be coating the rollers there and as they become less tacky, they cannot feed paper correctly.

Then plug the printer back up, take your paper out and replace it with a fresh, small stack (about 5 pages) of paper. Quickly bend the stack in an 'S' shape a few times to separate pages. Make sure it is lined up on the right side of the paper feed and the paper guide on the left is snug on the left side of the paper. Then try to form feed again. If that works, then try to print the self test page.

Please follow the steps given below to perform the self-test:

1. Make sure the printer is in “Copy Mode.”
2. Press the “Menu” button once.
3. The screen will display “Copy Menu: Copies”.
4. Press the left arrow button once. The screen will display “Copy Menu: Tools”.
5. Press the check button once. The screen with read “Tools: Maintenance”.
6. Press the check button once. The screen with read “Maintenance: Ink Levels”.
7. Press the right arrow button until the screen reads “Maintenance: Print Test Page”.

try moving the small blue slider on top of the drum cartridge side to side 10 times.

Is this happening when you print or when you scan? If when scaning you could have something on the scanner bed... If this is happening when you print, it could be the cartride is defective.
