Polygons


The perimeter of a polygon is the length of its sides. The area is the space enclosed by the polygon.
The difference is similar to the difference between a fence around a yard and the space in the yard.

Where is the polygon motor for a sharp ar 235 located


The laser polygon motor is located direrctly under the scanner unit. To get to it you have to take the control panel off and you have to take the cover off where the paper exit on to. It's a bit tricky to get to, but is right under the cover. You will need some short or angled screw drivers. I use a right angle tool from Makita.... It is a usefull tool. If you have a finisher on the copier, you will need to take it off & remove the bridge attached to the under side of the scaner. There maybe another **** problem with getting the cover off the laser unit > It may have secruity torn screws in it?? The laser unit will have four screws that hold it in place..... Good Luck....

Error 320


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.
