Question about Xerox Phaser 8550DT Thermal Printer
That is a problem with the print head tilt or side to side movement.First remove the right and left covers. Then on look on the left side ( looking at the machine from the front). About mid way back toward the bottom of the frams you will see a stainless steel block, about 1 inch square. See if there is ink in it. Normally you will see some yellow ink buildup in that block. There is a spring on a bracket that you have to slip off to remove and clean the block. If excessivly filled witih ink you may have to use some channel lock pliers to remove it. Soak the block in some pretty warm to hot water to slften the ink and clean the block and shafe off thoroughly. Then clean the print head shaft and remove as much loose ink as possible.
The second most likely problem is that the print head wiper blade has stuck to the print head. You then have to remove the ink loader, ( where you insert the ink sticks. Once that is removed you can access the print head/drum area. The blade is pink in color and if tacked to the print head, remove gently. Then run a couple of cleaning cycles and also the remove light stripes cycle. The blade will mostly stick if the machine it shut off improperly or there is a power failure. The clutch that drives the wipe may be bad, although far less likely.
Those are the 2 most common problems that give that code. I would say those 2 resolve that problem more than 70 percent of the time. But that code means the print head is not moving side to side or front to ack properly.
Hope this helps , it should.
