4. PRINTING PROCESS

1 December 1993

1. Master Ejecting: Ejects the used master wrapped around the

drum into the master eject box.

2. Original Feeding: Transports the original to the scanner section.

3. Scanning: Scans the original image with the CCD through

the mirror and the lens while feeding the

original.

4. Master Feeding: Converts the image signal read by the CCD into

digital signals and sends them to the thermal

head to plot holes on the master. The master

then wraps dround the drum.

5. Paper Feeding: Sends paper separately to the drum section.

6. Printing: Presses the paper fed from the paper feed

section to the drum. This transfers the ink to the

print through the drum screen and the master.

7. Paper Delivering: Peels the printed paper with the exit pawl and

air knife and ejects the paper onto the paper

delivery table.
