Did you clean the Corona wire?
Sometimes the Laser/scanner unit has toner debris, that is obstructing the light.
and lastly the Fuser may have a worn film.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it and give a testimonial for my response

Thanks, Joe

Why is there black line printed across the page in 3 different areas when something is printed. I changed the toner catridge.


This is nearly always the fault of the toner cartridge. The previous cartridge may have left toner on the transfer roller and this may have contaminated the new toner cartridge. Take the toner cartridge out and inside the printer under where the toner cartridge goes you will see a felt roller that goes across the printer and has a gear at one end. Wipe this roller with a dry clean lint free cloth, rotating it to make sure it is completly clean.
Check the blue coloured drum on the toner cartridge to see if there is a black line going across it. If so clean it with the same dry clean cloth.
If this does not work then I suggest you buy a genuine toner cartridge and try that.

Hi Everytning I print has a very narrow pink line straight down the centre of the page, also every so often the print has a black/yellow/blue/pink thick line running across the page. Thanks


The narrow pink line is coming from your magenta toner/drum cartridge. You may be able to open the from cover and look at the 4 toners. If you look at the magenta (like pink) cartridge, you might see the thin line on the drum surface.
The multicolored band that sometimes shows up on your prints is most likely the transfer belt unit. This is caused by an area of the belt that is not being cleaned very well. This probably tends to show up when you are running mutilple prints of a page.
So it looks like to may need to replace your magenta toner and look at getting a transfer belt unit.

Xerox Phaser 7700 printing Black line across bottom of every page


The line could be caused by contamination on the black laser lens. Try using the cleaning wand located in the front door to clean the lens. You will need to remove the waste toner container to access the wand slots. If that does not solve the problem, the black developer housing may need to be replaced.

HP 2600N PRINTS A BLACK LINE VERTICALLY ACROSS THE PAGE (FROM TOP TO BOTTOM) RIGHT IN THE MIDDLE EVERYTIME YOU PRINT SOMETHING . WHAT COULD THIS BE? I HAVE CLEANED EVERY DRUM, THE FILM ETC AND IT KEEPS...


You either have a defective black toner, a bad fuser or transfer belt. From my experence it is usually a bad toner cartridge. After you print a couple of pages, pull the black toner and see if there is anything on the drum. If there is try shaking the toner, sometimes toner does like dirt and clogs up. If you still have problem you will have to try another toner. I know that is not cheep, but I don't know any other way.

Xerox XC1020 White Bands running across copied page 4" apart


The metering blades in those cartridges go bad and do not allow the ink to get to the page. Look at the front of the toner cartridge, is should be a solid consistent black all the way across, if its streaky, not consistent all the way across replace the toner.
The other problem could be a dirty laser. If replacing the toner doesnt work let me know, I will tell you how to remove and clean the laser.

Horizontal black lines across page.


Horizontal lines usually indicate a toner cartridge that is not cleaning properly.

A. If the distance between defects is 38 mm (1.5 inches), 47 mm (1.85 inches), or 94 mm (3.7 inches), the print cartridge might need to be replaced.
B. Clean the printer.

1. Clean the inside of the printer and run a cleaning page to clean the fuser.

Over time, particles of toner and paper accumulate inside the printer. This can cause print-quality problems during printing. Cleaning the printer eliminates or reduces these problems.

To clean the inside of the printer
1. Turn the printer off and unplug the power cord.
2. Open the top cover.
3. Remove the print cartridge.
4. With a dry, lint-free cloth, wipe any residue from the paper path area and the print cartridge
cavity.
5. Reinstall the print cartridge and close the top cover.
6. Plug in the power cable and turn the printer on.

Cleaning the fuser:

Run the printer cleaning page to keep the fuser free of toner and paper particles that can sometimes accumulate. Accumulation of toner and particles can cause specks to appear on the front or back side of your print jobs. To ensure optimum print quality, HP recommends that you use the cleaning page every time that you
replace the print cartridge or on an automatic interval that you can set up. The cleaning procedure takes about 2.5 minutes to complete. A CLEANING message appears on the printer control panel display while the cleaning is taking place.
To run the cleaning page:

In order for the cleaning page to work correctly, print the page on copier-grade paper (not bond, heavy, or rough paper).
1. If your printer model includes a duplexer, open the rear output bin.
2. Press Menu to open the menus.
3. Use (Up button) or (Down button) to scroll to CONFIGURE DEVICE, and then press (Select button).
4. Use (Up button) or (Down button) to scroll to PRINT QUALITY, and then press (Select button).
5. Use (Up button) or (Down button) to scroll to CREATE CLEANING PAGE, and then press (Select button).
6. Follow the instructions on the cleaning page to complete the cleaning process.
7. If your printer model includes a duplexer, close the rear output bin.

If this helps resolve the problem, please post a reply. Binary Bob
