Sequence of operation
Table 1-1 Sequence of operation
Period Duration Purpose Remarks
WAIT From the time the power is
turned on or the door is
closed, until the printer is
ready for a print operation
STBY (Standby period) From end of the WAIT or
LSTR period until either the
print command is received
from the formatter or the
power is turned off
INTR (Initial rotation) From the time the print
command is received until the
media is picked up
PRINT From the end of INTR period
until the fuser paper sensor
detects the trailing edge of
paper
LSTR (Last rotation) From the end of the PRINT
period until the delivery motor
stops rotating
Clears the potential from the
drum surface, adjusts the
drum phase, and cleans the
ITB
Maintains the printer in
readiness for a print
command
Prepares the photosensitive
drum for printing
Forms the images on the
photosensitive drum and
transfers the toner image to
the print media
Moves the printed sheet out
of the printer
Detects the cartridge
presence and environment;
completes any required
calibration (color registration
control and image stability)
The printer enters sleep mode
when the formatter sends a
sleep command, and
performs color registration
and image stability control
when the formatter sends
those commands
Performs image stabilization
at a specified print interval or
at specified times
The printer enters the INTR
period as soon as the
formatter sends another print
command

Engine control system
The engine control system coordinates all printer functions and drives the other three systems.
The engine control system contains the DC controller, high-voltage power-supply PCA, low-voltage
power-supply unit, and fuser control.

Laser/scanner system
The formatter sends video signals to the DC controller, which controls the laser/scanner. When the
laser/scanner system receives those signals, it converts them to latent images on the photosensitive
drum.

Laser failure detection
The optical unit failure detection sensor manages the laser/scanner unit failure-detection functions. The
DC controller identifies the laser/scanner unit failure and notifies the formatter if the laser/scanner unit

Image-formation system
The image-formation system forms a toner image on media. The product includes four toner cartridges
that contain the toner. Toner is applied in the following order, using only the colors necessary for a
specific image: yellow (Y), magenta (M), cyan (C), and black (K).
