CHAPTER 8: PRINT DRUM SECTION

Mechanism

1. Master on the Drum Check Mechanism (Before Printing)

The machine checks for the presence of the master on the print drum at the start of a print job..
With a push of the Start key to begin the printing operation, the print drum starts to rotate and at drum angle
40 degrees from the position-A, the master sensor checks if a master is wrapped on the print drum or not.
If a master is found on the print drum, the printing operation takes place, but if a master is not detected, the
machine stops. Once the master is detected on the print drum, the information is memorized on the machine.
The master sensor no longer checks for the master on the print drum from the next printing job until a new
master is made, print drum is pulled out of the machine, or the power to the machine is turned OFF.
Print drum at 40
degrees from
