Polygonal mirror motor error.The polygon mirror motor does not reach the operating speed within 10 sec or the polygon motor remains out of the operating speed.Possible cause:defective polygon mirror motor,loose connection between the polygonal mirror motor and the BICU,defective cable between the BICU and the polygonal mirror motor or defective BICU.Turning the main power switch OFF and ON resets the SC codes if the error is caused by incorrect sensor detection.

Are you sure of the code? I don't have the exact manual for that, machine but the number seems strange. "5xx" errors are usually related to the fuser, so could be a bad lamp, thermistor, or fuse. see note to reset (if there is not a problem) as follows:
There are 2 levels of service call conditions.
Level Definition Reset Procedure
"A"
To prevent the machine from being
damaged, the SC can only be reset by a
service representative.
The copier cannot be operated at all.
Enter SP 5-810 (SC code reset) and
select “1”. Then hold down the Original
type key and the OK or ! key at the
same time (this does not require the
main switch to be turned off and on).

Polygon mirror motor error/lock. Unplug the copier. Wait 20 seconds. Plug it back in. See if that makes it go away.

Otherwise you should get a hold of a service technician but getting parts for a 250 is very tough. It could be the polygon motor, the power supply, a cable, or a board. It will take some time to troubleshoot.

YOU NEED TO RESET THAT CODE

Yes this is a Polygon Mirror motor error it is reasonably common in the Lanier digitals. The mirror motor can be ordered separtetly to the laser unit.
