The DC controller in the engine-control system controls the operational sequences of the printer. The
table below describes durations and operations for each period of a print operation from when the printer
is turned on until the motor stops rotating
Normal sequence of operation

STBY (standby) From the end of the WAIT or LSTR period until either
a print command is sent or the power switch is turned
off.
Maintains the product in printable condition.
INTR (initial
rotation)
From the time the print command is received until the
temperature of the fuser unit reaches its targeted
temperature.
Starts up the high-voltage biases, the laser/scanner
and the fuser unit for printing.
PRINT From the end of the INTR period until the last sheet
completes the fuser operation.
Forms the image on the photosensitive drum based
on the VIDEO signals from the formatter. Transfers
and fuses the toner image to the paper.
LSTR (last
