Fix a xerox 6350DT


If you have a white stripe in only one color, then you might have a bad developer. Each color has its own developer
116-2008-00 Yellow
116-2009-00 Magenta
116-2010-00 Cyan
116-2011-00 Black

Changing the developer is not super easy. You'd have to remove the left cover, HV Power Supply board, then remove Image Unit and the Developer Frame, where all the Developers are mounted. Detach the feed hose for the Developer you want to change and release the Developer's 2 spring clips.

The attached photo shows old developers which have dead spots that would cause the missing stripes on prints.

I'm getting a line that isn't printing through my printing from a Fuji Xerox DocuPrint C3055 DX


Possible reasons are: 1.empty toner cartridge, 2.dirt under one of the toner cartridge's developing roller, 3. dirt on the primary charge roller in the drum cartridge, 4. obstacle on the laser path.
Replace the empty toners first and try printing again. Follow the next steps if it didn't solve the problem.
Print a test page with 4 stripes across the page - black, cyan, yellow and magenta. See if all have the missing toner line or only one of them. If the white stripe is going trough only one color, inspect the cartridge with that color. It has to have the same stripe on the developing roller. See if there is some dust beneath it that makes the stripe and clean it with a brush. If the stripe is across all colors, then inspect the drum unit. The drum itself has to be evenly shining on the light. If there are uneven matte tracks on it, consider replacing. There should be a gap somewhere for the laser beam to pass and the drum is visible trough it. Look trough it for obstacles like piece of paper or hair. The primary charge roller has to be close to that gap inside, touching the drum. Look for dirt on it. Clean if possible.
Toner cartridges last approx. 6500 pages. The drum cartridge lasts between 14 000 and 28 000 pages depending on the color use.

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.

Faded stripe down the printed page


I found a solution that worked to eliminate the faded black stripe down the page thanks to a post by slamfix in another forum. The problem is related to ink build up on the blade edge of the black developer assembly in the imaging unit (the imaging unit contains 4 separate developers - yellow, blue, magenta, and black). The solution involves taking out the imaging unit, removing and cleaning the blade edge of the black ink developer until smooth. It took me about 15 minutes to complete and was fairly straightforward.

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.

Phaser 8560 magenta ink not transfering to paper


Hi jbasset285: Your printhead may be bad do to third party ink.
Try these steps first.
Diagnosing Print-Quality Problems
The Troubleshooting Print-Quality Page provides a good overview of the most
common print quality problems. To print the Troubleshooting Print-Quality Page,
follow these steps:
1. From the Control Panel, scroll to Troubleshooting, then press OK.
2. Scroll to Print Quality Problems, then press OK.
3. Scroll to Troubleshooting Print Quality Page, then press OK.
The Troubleshooting Print Quality Page includes instructions for printing the
Eliminate Light Stripes test print. These instructions are also provided on the next
page of this manual. The Eliminate Light Stripes test print indicates individual weak
or missing jets or an obstruction in the imaging path that affects a vertical band down
the entire page. Also, you may see color variation from jet to jet on the Eliminate
Light Stripes test print. Some variation is normal, occasionally occurs, and usually
self-corrects within a few printed pages. If a print-quality problem is not resolved
with the information provided in the Diagnosing Print-Quality
