Paper Feed Unit No. 2 (Optional) Operation
The Paper Feed Unit No.1 always takes priority. The Paper Feed Unit No. 2 becomes operational only when the cassette No.1
runs out of paper and the NP Sensor is deactivated, causing the nPCHK1 output signal level to go High.
1. The printing operation begins when the nPRNT (Print Request) output signal level goes Low. The Printer Motor (626) is
initialized.
2. The Paper Feed Solenoid (908) is energized for a specified period of time and is turned ON. This activates the Paper Feed
Roller (911), which rotates one revolution. The paper is separated into individual sheets by the L and R Paper Separation
Clips (809) (811) and transported to the Feed Roller 2 (904).
3. After one revolution the Paper Feed Roller (911) stops, releasing the paper. The Feed Roller 2 (904) and the Feed Roller
(526) transports the paper to the drum area.
4. The actual printing process starts at a specified time after the Timing Actuator (609) is activated and stops at a a specified
period of time after the trailing edge clears the Timing Actuator (609).
