1912 Registration (Main Motor) Motor Speed-up
This SP can increase the speed of the main motor just before the trailing edge of
the paper leaves the nip of the registration rollers.
ƒ Normally, the speed of the fusing roller is slightly faster than the speed of
the registration roller in order to pull the paper taut and stabilize paper feed.
ƒ However, this small difference in speed between the rollers can cause jitter
when the trailing edge of the paper leaves the nip of the registration rollers.
ƒ In order to prevent this jitter, just before the paper leaves the registration
roller the speed of the registration roller can be increased slightly to match
the speed of the fusing roller.

1915 Motor Speed Adjustment
The fusing roller rotates slightly faster than the registration roller in order to keep
the paper taut in the paper path. In some cases, this can cause "jitter" when the
trailing edge is released by the registration roller. To correct this problem, this SP
can be set to reduce the speed of the fusing roller just before the trailing edge of
the paper is released by the registration roller in order to reduce the effect of the
trailing edge snapping away from the registration roller.
