ITB Unit Lock Bracket. There is a new lock plate on the right front side of the ITB unit. This plate must be removed in order to remove the ITB unit. (x3)
Negative paper transfer bias roller. The negative paper transfer bias roller in the ITB unit is now a PM part.
Front Edge. The front edge of the ITB unit has been modified slightly to make it stronger. The front plate rests firmly on top of the head of a screw on the bottom plate to keep the plates apart. This strengthens the ITB lock mechanism. This change was implemented to reduce the false occurrences of SC471-10 (Belt Position Ready Timeout) and SC471-02 (Belt Centering Roller HP Error) caused when the ITB lever does not correctly lock in place.
ITB Replacement: Jigs. The inner side of the drawer right cover has been redesigned to accommodate the addition of the Jam LEDs (described below). The jigs required for ITB replacement are stored inside the ITB cover at the same location, but the large jig [A] is set on the left and the small jig [B] is set on the right. The jigs are held in place with Velcro fasteners.
ITB Stay Removal. The attachment of this long stay is more stable so it does not fall free and damage the belt during the transfer belt replacement procedure. The "U" configuration of the connection point, which allowed the stay to slip away freely, has been replaced with an "O" configuration that holds the stay in place until it is removed.
