Question about Xerox Phaser 8500/DN Printer
I've followed your other 10 posts on the subject but still haven't gotten it to work.
1. Power Cycled 5 or 6 Times
2. I took off all covers and on the left side found the circular spring that held in the 1x1 block. That moved freely.
3. Took the Ink Loader off and obsurved the movement of the print head. It moves to the left (when looking from the front) and then tilts backwards fine. I can see the wiper move up and down, and it's able to shoot out a clean page just fine too, but it still throws up that error
You seem to be the most knowledgable, and I'd really appreciate some pointers!
I couldn't quite see how to get the print head out, but I'm assuming that's the next step. Also on the front side of the print head (towards the drum) there is ink on that, and the wiper doesn't quite seem to touch it - is that normal?
A little bit of ink in that area can be normal. Although I would clean it out if I were in there.
To remove the print head, you have to remove that block. Then on each side of the print head there is a plastic bracket held in with one screw on each side. They are brass torx screws, they just lift out of the frame on each side of the print head, they are the print head latches.
You mention the head tilts backrward fine, but don't mention it moving forward. Does it get within about 1/4 of an inch of the drum? Is shoul dmove frely forward also. But removing it may be find the problem.
Remove the loose ink.
One other thing to check is the process drive motor. It is mounted on the right side of the machine and has a gear cluster on it. On the clear plastic are timing holes to ling up the gears to the frame. You can just pin them with paper clips. You have to remove the motor to do that correctly, 4 screws and some connectors run across the assembly. Remove it and pin the gears through the holes and when installing make sure the arrow on the frams lines up with the one on the assembly.

This fault occurs due to the printhead being stuck in the tilted position.
There are many reasons why this fault will occur, too many to mention.
More often than not, your problem will require the printhead and process gear to be re-aligned in order to get a reboot but sometimes it is possible to get a reboot by doing the following;
Turn the printer off, wait ten seconds then turn it back on again. Wait for the printer to start warming up to about 5 or 10 percent. At this point, switch the machine off again by the machine switch NOT your wall/plug switch. Wait ten seconds and switch on again. Now let it run through its normal cycle. The success rate for this method is small, possibly only 1 in 30 machines will recover.
The reason this will sometimes work is that, when you turn the machine off from the warm up, it powers down using its proper head parking routine, you will notice, it takes a while to shut down. If the original fault was due to say a power cut or someone pulling the plug out it is possible for the printer to find its home position and boot ok.
Unfortunately, a lot of the time, the reason for the fault is printer related and such, this method does not work. But it is always worth a try.
Hope this helps.
