When the source of paper is selected, the signal
is generated to start advance pickup.
Potential control is used during INTR for
the following:
1. 10 min after the main power switch
has been turned on.
2. 60 min after the main power switch
has been turned on.
For 4-on-1 or other layout processing, the signal
is generated after reading all originals.
Printing is ready after a single line of data has been
written in the page memory, generating this signal.

Before forming an image, a series of
charging operations is executed to
stabilize the potential of the drum.
During continuous printing, the high
voltage is not turned off even between
sheets to stabilize high-voltage output.
