SECTION 3
FUNCTIONAL OPERATION
13
Printer Functional Description
1. A Photosensor located on the Printhead Carriage sees the lead edge of the media, signals the
Driver Motor to reverse and aligns the media with the Printhead Carriage, and signals the Print
Engine on the Main Board that the mailing piece is ready for printing. 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 no records
remain to be printed.
5. When there are no records to be printed, the Printer ejects any media that is in line for printing.
The Feed Clutch is off at this point.
