12.6 Drive/Transport Systems Operation

12.6.1

Drive System

The Printer's drive system consists of the paper feed drive motor, above cutter roller drive
motor, process drive motor, and the fuser unit drive motor. There is also a motor for the
developer and cutter drive system which can operate independently.
(1) Process drive motor
This motor drives the registration roller, drum, cleaner auger, and transfer roller.
The registration roller and transfer roller have a clutch for drive transmission and the paper
drive can be turned On or Off based on the operation requested.
(2) Above cutter drive motor
This motor drives the above cutter roller.
(3) Paper feed motor
This motor feeds and rewinds the roll paper.
(4) Developer unit drive
The developer unit's drive system is driven by the developer motor (GM01) found in the
developer unit itself. A stepping motor is used for this drive motor, and the agitator and sleeve
are driven by a gear transmission.
(5) Fuser unit drive motor
The fuser unit's drive system is driven by the fuser unit motor found in the fuser unit itself. A
stepping motor is used for this drive motor and the heat roller, backup roller, suction belt system,
and output paper roller are driven by a gear transmission.
12.6.2

Paper Transport System

(1) Paper feed unit
(a) Paper feed unit structure
The paper feed unit is made of one to two drawers (depending on the model) that can each
contain a roll of paper.
(b) Paper feed/print operation
First print
The first page printed (after the power is turned on, first page of intermittent printing),
requires the photoconductor drum to spin up first. Therefore, when a print request is
received from the controller, printing will not start for approximately 6 seconds (the time
required for the drum to spin up) until the light exposure begins.
Intermittent printing (paper switch printing)
If the page size for the first set of data is different from the next set, a paper switch
operation will be performed.
Continuous print (for copies)
When performing continuous printing (copy), the lead edge of the next sheet of paper is
gripped by the registration roller before the first set of data is output in order to reduce
printing time.
Continuous print (with a spool and when controller processing finishes in time)
Even with different sets of data, if the paper size is the same and the controller finishes its
processing in time, the Printer can output at the same interval as when it performs copy
printing.
