Question about Xerox Phaser 8560DN Laser Printer

1 Answer

Light stripes I have chunks of one color that's missing. I've run all the maintenance and fixes. Is it time for a new maintenance kit? I've run about 7000 pages. Xerox says it needs service but their rates are ridiculous. Thanks, Jon

Sadly the print head probably failed. Thats not uncommon. Yeah, even at 7000 pages.
If it is just one color, the problem is a jet. If it were a blade or maintenance kit, the problem would be with all colors.
You have some blocked jets. If you have run eliminate light stripes 3 or 4 times and it hasnt cleared, chances are the print head would have to be replaced.

I have light vertical stripes on a dark picture and dark stripes on lighter colored pirctures. I have cleaned the head about 15 times and it is worse now than before. I am wasting ink and getting nowhere....


Have you checked the maintenance kit? Is the white roller badly contaminated? The mylar blade dirty?
If that is ok, then you may have a bad print head.

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.

Bad streaking on print xerox 8550 phaser tried the troubleshooting feature/eliminate light stripes with no luck


The best way to tell if your problem is clogged jets, or bad maintenance kit, or something blocking jets. Is to look at light stripes test, and see if missing jets are all in a straight row or all over the place. If the missing jets number less that 10 you can use jet substitution to avoid the streaks. If you are using Media Sciences or some other after market ink, check that most of your problems are not in the cyan area. Media Sciences produced a bad batch of cyan which clogged the jets pretty bad. The good news is that if their ink caused the problem they will pay for some one to come out and replace your printhead. If you LST (Light stripes test) has a smear the entire vertical lenght of the page. You have either a bad maintenance kit, or a piece of paper, lable etc..rubbing against the drum while printing

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.

Persistent Light Stripes


Some thoughts are these. 1. Is your maintenance kit new and in good shape. 2 There is a remote possibility that the cleaning blade has buildup on it. But most of the time in that situation the print head is bad. Moreso likely if you use non Xerox ink sticks.

8550DP Maintenance Kit


First of all make sure it is the right kit. The part numbers for teh 8550 and 2424 are very close, one ends in 675 the other in 657, so they have been known to be mixed up.
then here is the documentation..

Problem:
The machine displays the Replace Maintenance Kit after the Maintenance Kit has been replaced.
Cause:
There may two causes for this issue.
  1. The machine does not recognize that the Maintenance Kit was removed. This would likely be caused by a defective Drum Maintenance Pivot Plate.
  2. The machine corrupts the CRUM on the new Maintenance Kit. This may be caused by a defective Drum Maintenance Pivot Plate or IO Board.
Solution: thumbsup.gif Fixed! thumbsdn.gif Did not fix.
  1. While the Replace Maintenance Kit message is displayed, remove the Maintenance Kit. If the displayed message does not change to "Maintenance Kit Missing," replace the Drum Maintenance Pivot Plate and install a new Maintenance Kit.
  2. While the Replace Maintenance Kit message is displayed, remove the Maintenance Kit. If the displayed message changes to "Maintenance Kit Missing," replace the IO Board and then install a different NEW Maintenance Kit. If the problem persists, replace the Drum Maintenance Pivot Plate and install a different NEW Maintenance Kit.
