Question about Xerox Phaser 8500/DN Printer

1 Answer

8500 phaser timing

Still have timing problem. Gears grind when starting up.
I have set the module of gears on the right side, holes lined up in gears and lower gear at arrow. Upper gear hole up and a little to left. Head free and wiper down. Gears on left all run free and square block cleaned. Any thing else I need to do? It did pass a page clear through a couple of times. Jams either in front or with page half out of top. Then stops with an error.
Errors I have gotten, 4,024.45:6975......08, 035.42:6975.......08,025.41:6975 in that order.
The maintenance module moves up and down and the drum turns off and on. Could it be a firmware problem? I have reset the Navram from the menu. Thanks for any and all help so far. Steve

    Thanks again.

    There was a chunck of cooled off ink under the plate.

    Earlier I found the black ink tray was pushed out of place and could have alowed it to leak.

    Problem fixed.........

Doubtful its the firmeware. The maintenance kit pressure plate with sensor is most likely the problem. Once teh process drive is times and aligned properly then the pressure plate is really the only thing left.

    It is the black flat plastic piece under teh maintenance kit that lifts it up and down. Located to the left and below the maintenance kit.

Gear grinding


Sounds like your Process Drive Assembly has broken its mounting posts and the gears are no longer meshing properly, causing the grinding noise. The drive assy is located on the right side of the machine toward the front. It is held in place with 3 screws. If you wiggle on the gear assy and it moves, then you should go ahead and replace the machine. This is not a do-it-yourself type of repair and should be left to a Xerox Certified Technician if you decide to repair the machine.

This is out of the service manual. Generally you can just remove the sides and home everything and it will work fine.

The 7,007.49, 7,008.41, 7009.42, and 7,010.43 errors indicate that the
Printhead was unable to tilt normally on its axis. Possible causes include:
■ The printer was powered off in the middle of a cleaning cycle and the
Wiper Blade has frozen to the Printhead.
■ A Drum Maintenance Camshaft lobe is broken and holding the Drum
Maintenance Kit’s oil roller against the Drum when it should be retracted
to its home position.
■ Process Drive not being aligned correctly.
■ A damaged Printhead Restraint.
■ Ink spilled in the Roll Block preventing proper Printhead motion.
■ Ink or other debris under the Printhead preventing proper motion.
■ The Wiper Assembly not being aligned correctly or ink spilled in the wiper
tracks.
■ The Head Tilt Gear not being homed correctly.
■ The X-Axis Motor nose cone not being installed correctly.
■ The ferrite torrid on the Printhead interface cable has slipped behind the
Printhead causing the Printhead to bind when it tilts backwards.
■ The black plastic shroud on the back of the Printhead is snapped off and
binding the Printhead when it tilts back.
Caution
After servicing the printer, manually set the following assemblies to their
home position before powering on the printer. See Section 6 for
instructions on setting these components to their home positions.
■ Printhead (tilted forward and disengaged from Printhead tilt gear)
■ Head Tilt Gear (disengaged from Process Drive train; arrows on left
frame point to each other)
■ Wiper Assembly (bottom of travel)
■ Process Drive (holes on Transfix Camshaft and Drum Maintenance
Camshaft line up with marks on frame, large gears within assembly
line up with holes in Process Drive housing)

Printer error on phaser xerox 8500 08 045 4348752 - can't find what the problem is


This error tells us that the Media Path Motor 807K16050 is bad.

This is usually caused by bad camshafts 008K02160 & 020K14800, so replace those too.

It is medium difficult and takes about 2-3 hours

08,007.41:8472 It's a phaser 8400 i have no idea what to do..What could it be?


Your print head wiper blade is not moving properly.

The clutch that moves the wiper may be failing.
That blade is located between the drum and print head.

Printhead Wiper Alignment: Rotate the left and right idler gears until the Wiper is all the way to the bottom and the gears cannot be rotated further. Rotating the left and right gears together ensures that the wiper stays parallel and does not pop out of the belts. Now rotate the left idler gear a couple of teeth to raise the left side of the wiper to the top. Make sure that the left side of the wiper is a bit higher than the right side. Might have to try this procedure a couple of times, a couple of teeth at a time, to properly align the wiper.

This error indicates the printer is not in its home position. To reslove you need to open the right side cover and near the mid top you will see 2 gears that is to the print head wiper make sure the print head wiper is all the way down. also make sure the print head is tilted back. Also there is a set of gears near the front and on the bigger gears there are holes line the holes up with the holes on the plastic the cases it.

Thank you

Xerox Phaser 8500n 70,010.43


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.
