Question about Xerox Phaser 8550DX Laser Printer

Possible Print Head Issue

Hey Everyone,

I swear I will post everyday! Just kidding, but seriously there is an issue with this 8550 and when you print you get three lines that run vertical across the page. I've done the clear smudges and vertical lines. The lines that are vertical are about 2cms wide with about 2inch gap until the next line. I printed the light stripe test page and the yellow has some black and the magent is faded and the cyan has missing jets. I printed several solid fill pages about 40 of each color and still have the same issue. I personally fill this is a print head issue. Does anyone out there know a fix for this? As print heads are about what I don't know $600-800.

    Once you do the jet substitution, if the lines are not eliminated, you need to replace the print head.

    Okey dokey. Moved up??? Like George Jefferson?? LOL.

    Been 31 minutes !!!!!!! hehehe

    How long have you had it?

    If you haven't had it that long and use Xerox ink sticks, I would press them for a print head replacement.

    Not normal for that print head to fail without much use.

    I don't think letting it sit would clog the print head.

    I would contact them and see what they will do for you.

    When did you buy it?

  • Rick Kasper Mar 26, 2008

    What happened? You didnt post today LOL

Hi I am not getting any Red from my printer

It's possible magenta ink to be finished, or the print head is dirty and it has dry ink on it. You must clean it with hot water. You must use the printer from time to time to avoid to dry the ink cartridge or print head.

My Xerox 8550 says 'ink sticks are jammed'. Yet,

This could be a print head problem. If the print head is calling for ink and the sensor is bad the ink melter will continue to melt ink and over flow the print head. In which case the print head need to be replaced.
Also it could be a problem with the ink melter. If it isn't melting the ink it will cause this error.
To get to the ones at the end of the chute I stick a long screwdriver and break it free from the melter.

Xerox Phaser 8550 having color quality issue

If you are using third party ink sticks contact the manufacture and they will, if you use enough of thier product, send you a new print head and send out a tech to change it. Media Science is the most likely source of third party ink.
You can also switch to Xerox ink sticks and the colors will be correct after several purges to get rid of the old ink.

A horizontal line appears on prints every 9/32 of an inch, especially on lighter prints

The following a step by step instructions for the printer issue:
Confirm the ink tank(s) are properly installed
Perform print head alignment
Perform Print Head Cleaning - iP4500
If the prints are faint or streaks are printed, the print head nozzles may be clogged. Those phenomena can be improved by performing print head cleaning or print head deep cleaning. Also, you can check the cleaning results by printing the Nozzle Check Pattern after cleaning.
Remove tape from the ink tank and make sure the air hole is clear

Phaser 8550 printer fault 37,008.44:25860

This is a pre heater error.

I would make sure the printer is connected directly into the wall and not into a power strip or UPC as these devices may create momentary AC voltage sags that could cause this error. If power levels going into the printer are good, you will need to contact Xerox for support

Error 13.0 on a Xerox 8550 codes on that machine are heating issues with the print head. Usually the print head has failed or the electronics module supplying the heater voltage.
Thats it in a nut shell.

Xerox 8550/DN Printing with usb problem.

I will offer some thoughts.
But thats weird .
Have you tried a new driver? Yeah I know, that doesn't make a lot of sense to me if the image is fuzzy, but since it will print a internal pattern clear and not a print sent from the computer, the driver may be the issue. I stress MAY be the issue.
What I suspect more is the drum encoder. When I hear about that machine bluring, that is the most likely cause. It picks up silicon lubricant from the maintenance kit and normally causes blurrs.
It is on the right side of the machine ( viewed from the front), track it from the drum shaft. It has a clear plastic cover over it, but it needs to be cleaned with alcohol to disipate the silicon lubricant from it.
No no not drinking alcohol, although that can make prints blurry LOL.. Hope you have a sense of humor. To many people today don't....................
