Re: my laser color 9420

Sometimes when toner starts to get low prints will faed or not print on sides. Make sure the printer is on a very level surface. Remove the toners and shake lightly left to right and reinstall.

I HAVE JUST REFILLED MY LEXMARK X2550 PRINTER COLOR CARTRIDGE NUMBER 35, BUT A MASSEGE ON MY PC SAYS: "Invalid Cartridge". How do l get it to be recognised so that l can use it?


35 is color ink cartridge .. high yield,

A new color print cartridge needs to be installed.

If available, click the Continue button on your computer screen to print using the

black (or photo) print cartridge. (The Continue button is available only at the

beginning of a print job.)

Note: A variable amount of ink remains in the color print cartridge.

Follow these steps to replace the color print cartridge in your printer:

1 Cancel the print job if not already canceled.

2 Replace the color print cartridge with a new cartridge. For more information,

see "Removing a used print cartridge" on page 35 and "Installing print

cartridges" on page 35.

3 Print again.

To order supplies, click Order Ink on your computer screen. You can also see

"Ordering paper and other supplies" on page 40 in this guide.

How to change ink in HP Deskjet F480 printer???

  • Check the ink levels by opening the HP Solution Center. Click on "Settings." Click on "Toolbox." Click on "Services." Click on "Service this device." Click on "Estimated Ink Levels." A graphic will appear showing the estimated ink level in each cartridge.
  • 2 Verify that the unit is on. Open the print cartridge door allowing the print carriage to move to the far right side of the unit. Once the print carriage has stopped, lightly press down on a print cartridge to release it. Pull the print cartridge toward you out of its slot. To replace the tri-color print cartridge, remove the print cartridge from the slot on the left. To replace the black or photo print cartridge, remove the print cartridge from the slot on the right. Place the cartridge in a plastic bag as it may still contain some residual ink and may leak.
  • 3 Remove the new print cartridge from its packaging. Remove the plastic tape by using the pull tab, being careful to not touch the copper-colored contacts or the ink nozzles under tape.
  • 4 Slide the new print cartridge forward into the empty slot. Gently push the upper part of the print cartridge until it clicks into place. The tri-color print cartridge fits into the left slot. The black or photo print cartridge fits into the right slot.
  • 5 Close the print cartridge door. If the print cartridge alignment sheet prints, load it on the left front corner of the scanner glass with the top of the page to the left. Verify that there is plain paper loaded in the input tray, and then press the "Scan" button to align the printer.

    Xerox Phaser 7760 prints white diagonal lines across the page. The pattern is pretty conisitent. It starts white on the left side of the page and white remains till the right end of the page. I have...

    Are the white lines in one color or all colors? If it is just one color you should try cleaning the laser window. Open the front cover and in the cover there should be a cleaning wand. Remove the waste cartridge and use the cleaning wand to clean the laser windows located behind the waste cartridge.

    Left side of page prints lighter than rest of page

    You should contact Dell about returning these for a replacement, it sounds to me like a manufacturer's error.

    Every page covered in magenta and black won't print across the page

    This is caused by toner contamination in the laser scanner unit, it is quite a complex job removing and cleaning the laser scanner. I would suggest you contact HP regarding the repair.

    Page count unreasonable

    Re you using genuine HP NEW cartridges? If not, you must make sure that whoever has re manufactured the ones you are using has replaced the chip on the cartridge. This tells the machine how many copies are on the cartridge.

    HP Color Laserjet 3500 printer - no black on left side of page

    The folded paper solution for for me. Thanks to all for sharing!!!!

    I had the same problem. No black or cyan on the left side of the pages. From this advice... I folded a stack of 4 pieces of paper in half and then half again. I took out the transfer unit and put the folded paper in the upper left corner and then put the transfer unit back in. WORKS BEAUTIFULLY! Thanks you all sooooo... much!
