PREVENTIVE MAINTENANCE (PM)
7 - 35
* K1: 2nd transfer roller
Since the bearing [3] is press-fitted in the bushing [1] and [2], be sure to remove it straight so that
it does not fall off.
Fig. 7-36
* K3: 2nd transfer roller side seal
Be sure to attach the 2nd transfer roller side seal according to the criteria in the figure below.
Part A: Pay attention to the following. If the blade is caught by the side seal or comes up on to it,
the blade may turn up. If the gap between the blade and the side seal is too wide, this will cause
toner scattering.
Fig. 7-37
After the side seals are attached, move the bracket retaining the blade and check that it is neither
caught nor comes up on to the side seal.
