SECTION 3

FUNCTIONAL OPERATION

Printer Functional Description

1. A Photosensor located behind the Sheet Separators sees the lead edge of the paper, another

Photosensor in the Print Engine sends a signal to the Print Engine on the Main Board that the

mailing piece is ready for printing. The Feed Clutch remains disengaged as long as a mailing piece

is in view of the Photosensor.

2. When the mailing piece uncovers the Sensor, the Clutch engages the Feed Rollers and the next

piece of media starts moving toward the Printer section.

3. This cycle repeats itself as long as there is media in the Feeder.

4. The cycle stops when the Feeder runs out of media, the operator stops the process, or there are no

records left to be printed.

5. When there are no records to be printed, the Printer ejects any paper that is in line for printing. The

Feed Clutch is OFF at this point.

Printhead Cleaning

The Printhead is cleaned at the beginning of each startup of a job by the Service Station and at times during

a run as determined by the Printer software. A separate Motor operates the Service Station.
