ƒ Changes to SP1916-51 to -53 affect the speed of the fusing motor.
ƒ For every change of "1", speed is adjusted 1/1848 = 0.054%.

1918 Fusing/Main Mtr Speed Change
These SP modes adjust the rate of the speed reduction between the main motor
and the fusing motor.
ƒ During normal operation, the line speed in the fusing unit is slightly faster
than the line speed at registration. This keeps the paper slightly stretched to
prevent wrinkling and skewing.
ƒ However, if the speed of the drum becomes slower as a result of a change in
the amount of buckle at the registration roller, the tension on the paper will
pull on the drum and rotate it faster than the rotation of the main motor. This
can cause image distortion at the two LPH joints.
