This is that the black drum unit cleaning blade failed or the charge roller has toner stuck on it. To remove the drum open the front cover and using the green tool right hand side of opened door undo the two screws turn the transfer lock into the unlock position and lift. Once you have done this then remove the black drum this is the one at the top by moving the little green tag to one side and pulling out (Be Careful as if you scratch the drum you will have other problems)

Once remove you will be able to see the drum and a black roller above it see if that has the black line on it. If it has then clean with some alcohol based cleaning fluid once this is done reinstall and then print. If there is no line on the black roller try above the likely thing is that the drum cleaning blade has worn and the unit will need replacing.

Glad to be of some help
Thanks J

Lines on print. There's are three lines on picture print only. Can't see the line on document. It's about 1/4 inch wide and going throught top to bottom.


Have ou gone into your menus. Into troubleshooting, then image quality.
You will want to run both the eliminate light stripes and eliminate smears procedures. that will purge the print head, blow air through the jets and hopefully resolve the problem. I do believe the 8550 has a Jet Substitutin procedure where you can do a workaround and make other jets make up for the light areas.
here are some directions, Will forward more

  1. Press the [Up] or [Down] arrow button on the Control Panel to select [Troubleshooting] on the Display Screen, and then press the [OK] button.
  2. Press the [Up] or [Down] arrow button to select [Print Quality Problems], and then press the [OK] button.
  3. Press the [Up] or [Down] arrow button to select [Troubleshooting Print Quality Page], and then press the [OK] button.
  4. Evaluate the 'Light Stripes Test' page for missing printhead jets, such as missing Cyan, Magenta, Yellow or Black color bars. The 'Light Stripes Test' page is the last page of the Troubleshooting Print Quality Page that printed.

    WARNING: To avoid injury, do not touch the sharp metal strip attached to the clear rubber wiper blade in the Maintenance Kit.

  5. Use a clean lint-free cloth or a new paper coffee filter to gently clean the maintenance unit's clear rubber wiper blade, use only a wiping motion across the entire length of the wiper blade, and then empty the waste tray. A dirty maintenance kit wiper blade can cause white lines and weak or missing printhead jets.

  7. Repeat step 3 to reprint the Troubleshooting Print Quality Pages. If there are no missing or partially missing color bars then the print quality problem has been resolved. If there are missing or partially missing color bars then the printhead cleaning procedure will need to be performed. Continue with the next section.
To clean the printhead using the basic eliminate light stripes procedure:
  1. Press the [Up] or [Down] arrow button on the Control Panel to select [Troubleshooting] on the Display Screen, and then press the [OK] button.
  2. Press the [Up] or [Down] arrow button to select [Print Quality Problems], and then press the [OK] button.
  3. Press the [Up] or [Down] arrow button to select [Eliminate Light Stripes], and then press the [OK] button.
  4. Press the [Up] or [Down] arrow button to select [Basic], and then press the [OK] button. The printer will perform a head cleaning, which will take about five minutes. The printer will then print a cleaning page and a light stripes test page.
  5. Repeat steps 1 - 4 one more time. If there are no weak or missing jets then the print quality problem has been resolved. If there are still weak or missing jets after two basic light stripe cleanings, continue with step 6.

    NOTE: Do not try the Advanced Eliminate Light Stripes Cleaning mode without performing two basic cleanings first.

    To clean the printhead using the advanced eliminate light stripes procedure:

  6. Press the [Up] or [Down] arrow button to select [Advanced], and then press the [OK] button.
  7. Select the missing jet color and number. If necessary, check the light stripes test page to determine the color and jet number of the missing jet.

    NOTE: Only perform the advanced light stripe cleaning once. If weak or missing jets still persist, continue with step 8.


  8. Print the Troubleshooting Print Quality Page. Evaluate the Light Stripes Test page for missing printhead jets, such as missing Cyan, Magenta, Yellow or Black color bars. If necessary, perform the basic eliminate light stripes procedure one more time. If the Advanced Eliminate Light Stripes procedure does not resolve the weak or missing jets, perform the Enable Jet Substitution Mode. See the Related Items below.

I have a Xerox Phaser 8400 with image problems. After power up it prints a Startup Page - That page is black text which faded and slightly distorted in some areas and in areas that are in Color only...


What you are describing is a bad print head. You can try running the eliminate light stripes several times, and jet substitution, but most likely the print head will have to be replaced to remedy your problem.
You can try googling. Phaser printer print heads or phaser printheads.
There seems to be a secondary market appearing for those print heads. I can tell you from Xerox, if you have no maintenance agreement, they cost $750 per print head.
Honestly, having worked on about every type of color printer known to man, the new solid ink phaser printers, produce a dry ink image of 2400 x 2400 dpi with ink particles that align end to end. The resolution of those printers are remarkable and can be purchased for less than the price of one of those new print heads.
Now for reliable, albeit somewhat not as sharp a color image, but still exceptional, you really can not beat an HP.
The ink stick technology really no longer has the color vividness advantage it initially had. The inks that align end to end, have ended that advantage and are sure a lot cheaper to operate per page.

Stripes on Images only - Text OK


Perhaps the CMY color heads need alignment. If you have not already done so, run a head alignment from the driver maintenance section. It will print out a page containing several lines and text, and request you select the closest-aligned images. After this is done, do another image print to check for improvements.
Normally, the printer uses the black cartridge for text and the CMY inks for images (even for black on photo and specialty paper). So when you are printing normal text pages on plain paper, only the black ink is used. A good check for this would be to print a normal text page, but select photo paper in the driver to trick the printer into using the CMY inks to make a substitute black text page. If this looks ok, then you are having issues other than cartridge alignment.

Broad light stripe down whole scan


Have you tried to do a cleaning of the color heads. Use a cotton swab, the same kind you use to clean your ears with rubbing alchy on it an clean the heads of the color injectors. If this dose not correct the problem then try changing out cartrages. IE if it is a grey stripe change out your black ink. If it is a pink stripe change out the color ink.
