I've been having a pinch roller error sometimes... both left and right even though they are in the right locations...I've done a search trying to find the problem, but i was wanting to ask you guys...A couple months ago I flipped the encoder strip over because it was struggling finding crop marks and cutting right....Now I'm getting this error....Do you think its the encoder strip, the cartridge cable...or the cable board thats attached to the top of the cartridge? It really doesn't matter how far i move the pinch rolllers in or out? It still has a hard time finding them from 7" to 29" (30 inch printer)??? Please help?
