Cassette lift operation (PF)
The lift-up operation keeps the stack surface of media in the paper feeder cassette at a specified
position to perform stable pickup operation.
The paper feeder driver drives the PF lifter motor (M1600) to move up the lifter plate in which media is
stacked. The cassette lift-up operation for the paper feeder is operated in the same way as that of the
product base.
The paper feeder driver monitors the PF media stack surface sensors (PS1601, PS1602) when the
product is turned on, when the PF cassette is installed or during a print operation to perform the lift-up
operation.
Cassette lift operation (PF)
1. Initial lift-up operation
The initial lift-up operation is performed if either one of the PF media stack surface sensors
(PS1601,PS1602) does not detect the media surface when the power is turned on or when
the PF cassette is installed. The paper feeder driver drives the PF lifter motor for a specified
period after both of the PF stack surface sensors detect media and lifts the stack surface tot he
pickup position.
The paper feeder driver determines a PF lifter motor failure and notifies the DC controller if
both of the PF media stack surface sensors do not detect media within a specified period
from when a lift-up operation is started.
2. During print lift-up operation
The during print lift-up operation is performed when the media surface is lowered for a
specified level due to a pickup operation. The paper feeder driver drives the PF lifter motor
for a specified period and lifts the stack surface to the pickup position when the PF media
stack surface 1 (PS1601) detects media absence during a print operation.
Cassette media size detection and cassette presence detection (PF)
The cassette media size and cassette presence for the paper feeder are detected in the same way as
that of the product base.
Cassette multiple-feed prevention (PF)
The cassette multiple-feed prevention for the paper feeder is operated in the same way as that of the
product base.
Jam detection (PF)
The paper jam for the paper feeder is detected by the DC controller of the product base.
