4. CB90 Paper Pushing Plate Motor Abnormality

CB90 refers to the pusher plate (part number: 4402353400 PLATE) on the saddle stitch and

there can be various causes.

Check the condition of the pusher plate (see Figure 3); it should be completely flat

with no kinks or bends in the lead edge 'castle' areas.

Clean and check the pusher plate home sensor (PI15S) – do not exchange sensors

in these finishers as they are not the same (see Figure 4). If you suspect the sensor

is at fault, order and fit the correct sensor.

PI15S

Cam Assembly and Spring

Check the condition of the cam assembly and that the spring is still attached (see

Figure 4). Also ensure that the bushings on both sides of the pusher plate assembly

are in good condition and not elongated (see Figure 4).
