( 3 ) uneven pressure across the heat roller fixing . Adjust the pressure roller ends ;
Frequent jams l0. occur when copying
Cause and Remedy :
This phenomenon is likely to occur pickup roller wear, the general performance of the frequent jams , multi- part paper jammed in the paper feed mouth, continuous copying also stuck a few sheets of paper , and sometimes caused due boundless pickup paper is not synchronized with the drum , the transfer bias , the paper not only half of the image , and the image of a black front left side , to determine whether the pickup roller has been used in the lifetime of the method is to rub with a cotton dipped alcohol or water test the pickup roller surface , remove dust, paper, wool , etc., and then continuous copying immediately , can be printed 30 , then if jams eased , then the pickup wheel wear is more serious, need to change .

l1. Jam Display lights, but no paper jam in the machine .
Cause and Remedy :
This occurs mostly paper path detection switch is dirty, due to insensitive , for example , large-scale engineering drawings Xerox 2080 copier , often show "Paper Jan Side ( jam in the middle ) , and can not continue copying machine and the inspection no paper jam , the case of multiple central paper path detection photoelectric sensor Q5 and Q6 contamination was caused by toner .
Some models will need to be adjusted , such as U-Bin3300MR after replacing the control board, prone to " jam ¢ß" signal, but the machine did not jam , then, should be adjusted to fine-tune the control board VR1, so TP8 for TP0 voltage of 7. 2V, " jam ¢ß" display disappears , usually as this occurs , treatment methods are not the same .
Third, other maintenance and troubleshooting common faults
