Xerox phaser 6360 laser failure code 10


You may have to replace the laser unit. Code 10 is a warmup failure. You need to reseat the connector to the ROS Harness first. If the issue persists, replace the laser unit. Issue persists, check continuity between pins J15 and J151. If there is continuity, replace the Engine Control Board, if not, replace the ROS Harness

The exact meaning of this error code ( 006-370 ) is <IOT ROS Motor Failure>. The SOS signal does not come from the ROS ASSEMBLY. What this means is the printhead, also know as Raster Output Scanner - laser unit. failed to generate a "start-of-scan" or SOS signal.

There is a humidity and temperature sensor in this printer that is designed to prevent the laser from being used in extreamly high humidity situations to prevent damage to the printer. This sensor rarely fails, and that is why it is the least likely cause of a true failure.

If in Fact you are in a high humidity situation. There is nothing wrong with the printer, and it will function normally when taken out of the humidity. Possibly running a dehumidifier in these cases will help. If this is not the case and are certain this is not the problem, then a true hardware failure has occured.

There are 3 possible causes for this failure, and they are listed in the most likely to least likely.

1) the ROS Assembly ( printhead, laser unit )
2) the PWBA MCU ( printed wiring board assembly - Machine control unit ).
3) Sensor assembly. ( humidity and temperature sensor )

Error code 11 phaser 7700 polygon motor failure


The polygon motor is part of the laser assembly, other wise know as the ROS, Raster Output Scanner.
It normally is not as simple as replacing the ros and moving on.
There are color registration adjustments to be done once the ROS is replaced. You can try contacting
https://www.partsdrop.com/store/
and seeing if they have one. That motor has the mirrors on it that rotate to focus the laser to the belt assembly.

Error 10 laser unit failure on phaser 7700GX


That requires the replacement of either the ROS ( laser) assembly or the MCU board. I have seen both cause that code and indicate the laser has failed.
ROS is the laser assembly.
MCU board may not be detecting the ROS.
It is possible the connector that runs from the ROS to the board is loose, you may want to disconnect and reconnect that.
If the ROS is bad, you also have to have a laptop to connect to the machine to align the colors. That is called the regicon adjustment.
