8.5 Manual Feed Pickup Unit

8.5.1 Pickup Operation

iR5065 / iR 5055 / iR5075 / / /
The presence/absence of paper in the manual feed tray is detected by the manual feed paper sensor (PS23). The manual feed pull-off roller is operated by the drive
coming from the main motor by way of the manual feed pickup clutch (CL3).
When the clutch engages, the holding plate solenoid goes on so that the manual feed holding plate moves up.
In response, the gear of the feed roller receives the drive of the main motor, causing the feed roller to make a single rotation for movement of paper.
While the feed roller is rotating, the paper is moved by the manual feed roller as far as the registration roller.

8.5.2 Detecting the Size of Paper in the Manual Feed Tray

iR5065 / iR 5055 / iR5075 / / /
The user may set the side guide of the manual feed tray to suit the width of paper he/she is using. The reading of the variable resistor that operates in conjunction
with the movement of the side guide is monitored by the DC controller PCB for detection of paper width. The machine does not have a specific mechanism to detect
the length of paper, requiring the user to specify it.
