Question about Sharp AR-160 Copier
OK, CH normally means the one of the covers(front or side panels) is open or the developer unit is unplugged try these to see if that fixes the problem. p.s When the covers are closed a small tab on the covers triger a interlock switch or optical switch. Hope this helps
