2.1.4 Paper Feed Mechanism
2.1.4.1 Paper Feed Sequence
Paper feed sequence is explained below. (See Figure 2-6 , Figure 2-7 )
1. Set a roll paper to the Roll Unit.
2. The Roll Set Sensor detects the paper. (If the roll paper runs out while being fed,
the Roll End Sensor detects the end of paper.)
3. By the driver force from the ROLL motor and PF Motor ( Figure 2-7 ), the Feed
Roller 1/2 and Inlet Roller rotate and feed roll paper. At this point, the Decurl
Roller warps the roll paper to eliminate the curl of paper.
4. Paper feeding stops when the leading edge of roll paper is detected by the Inlet
Paper Edge Sensor.
5. The Upper Paper Guide Unit operated by the APG Unit nips the roll paper.
(Refer to
2.1.2 APG Mechanism (p30) )
6. If the status of the Slack Sensor is “not shaded”, the ROLL motor rotates and
warps the roll paper.
