7.2 TRANSFER BELT LUBRICATION
The transfer belt lubricant bar [A] on the transfer belt cleaning unit [B] applies
lubricant directly to the transfer belt [C] after every copy.
The on/off movement of the transfer belt lubricant bar solenoid [D] which is
synchronized with the belt cleaning mechanism, pushes the lubricant bar
against the support roller [E] in the transfer belt unit.
Compared with the previous model, the amount of lubricant applied to the
transfer belt will stay at a constant level for every copy cycle. Because of
this, copy quality problems such as partial blanking of lines (due to
incomplete toner transfer) can be reduced.
