Making Two-Sided Copies - Canon GP215 Service Manual

3. OPERATIONS AND TIMING
I. Making Two-Sided Copies
1. Outline
Figure 3-629 shows the paper path used when making two-sided copies.
For the first side of a two-sided copy, the copy paper is moved to the delivery side once after it has been
moved through the fixing assembly. When the copy paper moves past the delivery sensor (PS7), the deliv-
ery roller reverses after a specific period of time*. The delivery roller motor (M8) turns ON a specific peri-
od of time after copy paper has moved past the fixing paper sensor (PS7).
For the second side of a two-sided copy, the delivery roller rotates clock wise**; then, the copy paper
is discharged.
