LASER CLASS 1060P Chapter 2: Technical Reference

Names and functions of parts:

1. Paper Guide

This guide can be adjusted to the width of the loadable recording paper sizes. It prevents the recording

paper from skewing during recording by accurately aligning the paper width.

2. Main Motor

This motor drives all the rollers in the paper supply section.

3. Lifting Plate

The lifting plate is held down by the pickup roller; when it is moved up by the work of the spring, the

recoding paper stacked on it will come into contact with the pickup roller for separation.

4. Pickup Roller

The pickup roller has a semi circular roller. This roller is rotated once, and operating together with the

lifting plate, feeds the paper one sheet at a time.

5. Paper Edge Sensor (PES)

This sensor uses an actuator to detect the leading edge of recording paper and sends detection information

to the PCNT board.

6. Pickup Solenoid

This solenoid controls rotation of the pickup roller. When the main motor is activated to begin paper

feeding, the pickup solenoid releases the pickup roller. When the pickup roller picks up a sheet of record-

ing paper and rotates one full turn, the solenoid locks the pickup roller again.

NOTE

Paper Feed Jam Detection Retry Function

Because the recording paper on this machine is loaded upright, the paper is sometimes

difficult to feed when there is little recording paper left or the recording paper curls. For this

reason even if the paper edge sensor does not detect the leading edge of the recording paper

within 3.5 seconds after the pickup solenoid releases the pickup roller the machine tries to

repeat the same operation before judging that a jam has occurred. If the paper edge sensor

still cannot detect the leading edge of the recording paper, a paper feed delay jam is de-

tected.
