Unit 11 laser polygon motor failure

Hello I found this for your error code.

Code

L6-10

Description

Polygon motor lock trouble
The polygon motor does not rotate. The motor lock signal is detected for 6sec or more after the polygon motor rotates. The motor lock signal is detected for 1sec during rotation of the polygon motor.

Causes

Polygon motor unit failure Polygon motor connection, harness trouble or disconnection MCU PWB failure

I would unplug the unit for a minute and let it cool, then restart it and see if it was a temporary glitch or if the polygon motor has ceased to funtion. You might try to see if the wiring harness has come loose, otherwise you are looking for a new polygon motor.
Here is a copy of the service manual.It also suggests running a SIM 61-1.

I found a replacement motor for the machine, to give you an idea what it will cost to replace, keep in mind if you don't have the ability to replace this yourself you will have to call a repair tech to come in and do it and you may expect the cost for that to be at least the same as the motor.

Hopefully it isn't a motor failure. Good luck.

L6 10 Content Polygon motor lock trouble

Details The polygon motor does not rotate.

The motor lock signal is detected for 6sec

or more after the polygon motor rotates.

The motor lock signal is detected for 1sec

during rotation of the polygon motor.

Cause Polygon motor unit failure

Polygon motor connection harness trouble

or disconnection

MCU PWB failure

Check

and

remedy

Check the polygon motor operation with

SIM 61-1.

Check connector/harness of polygon

motor

Replace the polygon motor.
Replace the MCU PWB.

If the polygon motor isn't working then you will neeto buy a new Laser Unit. They can be expensive if you can get one. To replace it will tak alot of disassembly as well. Might be better and more cost effective to get a new machine.

Hello. The Error 11, polygon motor failure is usually caused by the motor controller chip going bad on the mirror motor. We found some of the contorller chips and had them replaced. The refurbished laser units can be seen at: http://www.lpscomputer.com/p-3060-1-116-1110-00-laser-unit.aspx

The polygon motor failure is referring to the Laser Unit (part# - 116-1110-00). This issue somewhat common on the Xerox 7700. Unfortunately the laser unit must be replaced and is pretty expensive (around $1000) Replacing it isn't too hard though, just remove the right side cover and unscrew the two screws on the laser unit and unplug the two cables from the laser to the engine control board. If you do decide to repair the machine iteminc.com has the part online.

Since the polygon motor is part of the laser unit, it would cost about $200 plus labor to replace it

THIS IS THE TEXT FROM THE PHASER 7700 SERVICE MANUAL, HOWEVER, SEE MY COMMENTS AT THE END OF THE QUOTE.

11 06-372 ERROR 11 LASER UNIT POLYGON MOTOR FAILURE
Note If this failure reoccurs three times successively, an Engine NVRAM
value is set preventing further printer use until the Clear Tech Rep
Fault, Clear <09-380 ~ 09-383> is run.
Remove Rear Cover (RRP 1, on page 7-154).
Disconnect P400 (see figure page 2-46) and P401 (see figure page 2-46) on the Engine Control
Board.
Inspect both connectors to determine they are fully engaged as a unit. Re-engage, if necessary.
Note The two connectors can NOT properly seat into their socket(s)
unless they are both engaged as a unit. Ensure there is no
separation.
Carefully reinsert the plugs into their joint socket and FIRMLY seat them.
Replace the Laser Unit (RRP 38, on page 7-200).
Note Whenever the mounting screws for the Laser Unit have been
loosened, it is necessary to recalibrate the unit by performing the
RegiCon Adjustment Procedure beginning on page 4-124.
If the problem persists, replace the Engine Control Board (RRP 42, on page 7-206).

It has been my experience that 90% of the time the scanner motor (polygon motor) has gone bad. I have repaired many 7700 printers with this error by replacing the laser scanner. The part can be purchased at: http://www.lpscomputer.com/p-3060-1-116-1110-00-laser-unit.aspx

Error 11, laser unit polygon motor failure. If this fault reoccurs 3 times successively the 7700 . enter diagnostics and clear tech rep fault and clear this 09-380, 09-383.

This error usually means that the laser unit on the machine has failed. Just replace the laser unit part number 116-1110-00. I've bought couple of them from www.iteminconline.com. They also give good customer service for free and I think 30 day return if the part is not working. hopefully this helps

Yes the laser has to be replace.
If you have checked that all the connections from the laser to the engine control board.
If it all of a sudden gave the code 11 then that means you have to replace it.

That laser comes at a price of $500 to $700. refurbished.
part# 116-1110-00-EX

Polygon mirror motor not up to speed. Check the motor, you power supply, and the board the motor it connected to.
