1801-007: Fusing motor speed adjustment
Fusing motor speed can be adjusted in 0.01% steps.
Normally, it is at –0.4%.
The fusing motor normally turns slower than the transfer
roller, so there is some slack between the fusing unit and
the PTR.
If the paper is too slack, when the trailing edge leaves the
transfer roller, the sudden release of the trailing edge
causes the paper to spring outwards. Then, toner particles
will move around, causing the image at the trailing edge to
be fuzzy.
If this problem occurs, increase the speed of the fusing
motor (the designers suggest a setting of –0.25%, but it
depends on paper thickness; stiff paper will vibrate more,
causing more movement of toner).
Slide 249
It is recommended that a setting lower than –0.25% should not be used.
Otherwise. some types of thin paper could become creased, and there are
no separate settings for different paper types.
