Image Transfer and Paper Separation
This illustration shows the SP modes, which control these currents. The base transfer
current ('current' in the diagram) depends on SP 2-301. This is different for various parts of
the image, and is different for the by-pass tray; see the next page for details.
Currents applied to leading edge, image areas - by-pass feed
Transfer current can also be adjusted for the leading edge and the image area, and for
by-pass feed. The timing for starting to apply leading edge current, for the switchover from
leading edge current to image area current, and for switching off at the trailing edge can also
be changed.
The table below lists the SP modes you can use to adjust these settings.
