Sends paper from the paper-feed tray one sheet at a time.
Stops the paper sent from the first paper-feed stage, and accurately feeds
it to the print drum and pressure section.
The pressure roller presses the paper firmly against the print drum for
printing and feeding.
Removes the printed paper from the print drum using the separator, and
sends it to the paper-receiving tray.
Supplies ink from the ink cartridge to the surface of the print drum for
printing.
Clamps the leading edge of a master.
Peels the master from the print drum after use, and discharges it into the
master disposal box.
The lamp carriage and mirror carriage move, and the CCD unit scans the
original on the scanner table.
Transports and creates a master using the thermal print head, then
sends the produced master to the print drum, and cuts the master
material.

CHAPTER 2: MACHINE SUMMARY
[ 2 - 3 ]
Set an original, and press the Start key.
Master removal operation
Removes the used master from the
print drum, and sends it to the
master disposal box.
Master-making operation
The original is scanned by the image
sensor, and the image is transferred
onto a master by the thermal print
head.
Master loading operation
The produced master is wound
around the print drum and cut.
The proof-print is printed.
Printing operation
Paper is fed from the paper-feed tray one sheet at
a time for printing. The printed paper is ejected
out onto the paper-receiving tray.

CHAPTER 2: MACHINE SUMMARY
(1) When the print drum rotates, the scraper roller and
pickup roller also turn to feed paper. The stripper pad
allows only one sheet to pass through to the second
paper-feed area.
(2) The paper sent from the first paper-feed area contacts
the timing roller and guide roller, and stops temporarily.
This causes slight buckling of the paper.
(3) The timing roller and guide roller start rotating, feeding
paper to the pressure section. (This operation is referred
to as the “second paper-feed”. To prevent tension from
being placed on the end of the paper, the scraper roller
and pickup roller are free to spin.)
(4) When the paper is fed further in from the second paper-
feed area, the pressure roller rises to clamp the paper
between the drum and pressure roller to start the printing
operation.
(5) The printed paper is removed from the print drum by the
separator and separation fan. When the pressure roller
rises, the guide roller also moves up to prevent tension
from being placed on the tailing end of the paper.
(6) Then, the suction fan sucks in the air to keep the paper
firmly on the transfer belts while the paper is carried to
the paper-receiving tray.
(7) The next sheet of paper is sent to the first paper-feed
area, and the guide roller lowers.

CHAPTER 2: MACHINE SUMMARY

Master-removal operation
(1) The clamp plate holding the leading edge of the master
opens, and the master-release bar rises to lift the
master out from under the clamp plate
(2) The vertical transport rollers and print drum rotate,
thereby separating the master from the print drum and
sending it to the master disposal box.
(3) The motion of the compression plate starts, pressing
the master into the master disposal box.
Master-making operation
(1) The image sensor scans the original, and the thermal
print head transfers the image onto a master.
Master-loading operation
(1) The leading edge of the master is sent to a the clamp
plate on the print drum, and the leading edge is clamped.
(2) The print drum rotates to wind the master around it.
(3) The cutter cuts the master.

Mechanism
1. Main Drive Mechanism
When the main motor is turned on, the motor pulley rotates and the rotation is transmitted to the main pulley
by the main belt. The main motor FG sensor detects the speed and the angle position of the print drum.
