1912 Registration Motor Speed-Up Adj
Due to the occurrence of jitter with A0 SEF and other paper, at the trailing edge of the
speed of the registration roller motor is increased. The increased speed creates slight
buckling between the registration roller and the drum.
While using Cut Pattern 3 with a copy longer than 460 mm from the upper roll tray and
longer than 690 mm from the lower roll tray, when the trailing edge of the paper feeds
50 mm past the registration sensor, the speed of the registration motor is increased 20
pulses. This has the same effect as adjusting the feed motor speed with SP1801.

After the registration roller starts turning to feed paper, just
before the paper reaches the nip of the fusing roller, the speed of
the fusing motor is increased slightly while the paper is still in the
paper separation path. This raises the speed of the paper
separation belt and prevents skew.
This SP adjusts the length of time from when the speed of the
fusing motor is increased to when it returns to normal speed

[-25~+25/1]
The fusing motor of this machine rotates faster than
the paper feed motor to stretch the paper slightly and
prevent wrinkles between the registration roller and
the fusing unit. Stretching the paper excessively could
cause distortion of the image.
