Hello I found this for your error code.




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.


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.

I s a p e n t a g o n a p o l l y g o n ? I w a n t t o k n o w ?

It's my understanding that a polygon is a multisided plain figure ( a two dimensional figure.). This means that a triangle - 3 sides, a square - 4 sides, a pentagon - 5 sides, a hexagon - 6 sides, (I'm not sure but I think a seven sided figure is a heptagon?), an octagon - 8 sides, a nonagon - 9 sides, a decagon - 10 sides, etc. are each examples of polygons.

Polygon error. There is a LASER inside the machine which hits a 5 sided minor spinning at about 35000 rpm. That minor is spun my the polygon motor. More then likely you have a bad print head. That is what the entire assy. LASER/motor/Minor/Sensors are called. Power off/then on if it comes back have a technician looks at it.
