sharp ar-bc320 streaks

when printing or copying in color the machine is put cyan,yellow, and magenta streaks on the page. they are running from the top to the bottom and are repeating. they appear to be coming from the drums. has anyone seen this before? thanx

Check the DV drive gears for cracks, it's a known problem for streaks and bands on copies. The updated part # for the gears are NGERH1530FCZ3 and poly sliders have been added along with the gears. part # LX-W20094FCZZ.

are the drive gears you mentioned part of the dv unit or main drive? all three colors are doing the same thing.

if u pull out the drum and toner cart. u will see the white drive gear in the back. if u have smaller hands and arms u can pull the primary transfer out and reach in and replace them easily. the gear is more than likey ur problem

The gears most likely have small cracks in them, They are used for cmyk toner/dv units, same gear and part # for all the units.

Totally agree with the above.

However, the latest part number for the gear is NGERH1530FCZ4. It is a stronger plastic.
My experience is the poly slider makes little difference. I've had a couple of gears still crack with the poly slider in place, even with FCZ3 or FCZ4 in use.
