This started suddenly. Every successful feeding is after a retry i.e. the machine can print 10 copies in 20 cycles. When I inspected the pickup rollers, They seem to fail to rotate in the first attempt and then rotate after a retry. This however does not print more than 10 copies before it stops with 'Paper jam in paper feed area.' Registration is normal except after jam detection, so I rule out timing. I have changed the pickup rollers but no luck. I have checked and adjusted to stack switch with no luck. Any ideas??
