● Multi-Porpose Tray Last Paper Detection
This Host Machine detects whether the paper picked up from the Multi-purpose Tray is the
last paper.
When pickup is performed from the Multi-purpose Tray, the feed distance from the Multi-
purpose Tray Paper Presence Sensor to the Registration Roller is short, hence before the
no-paper in the Multi-purpose Tray is detected, the next image is started to be formed. And
to prevent the Photosensitive Drum and ITB from toner soiling, the DC Controller detects the
last paper of the Multi-purpose Tray through the Last Paper Sensor.
When the last paper is detected, the message indicating empty paper is displayed in the
Control Panel.
The following figure shows last paper detection mechanism.

● Registration Control
This is the feed control executed to make the image fit in the paper.
Based on the leading edge detection by the Registration Sensor, either non-stop registration
control, which increases/decreases the speed without stopping paper feed, or stop
registration, which temporarily stops paper feed, is used according to the situation.
Constant speed
1/2 speed
1st side
2nd side
LTR or Smaller
Non-stop registration
Stop registration
Larger than LTR Stop registration
Non-stop Registration Control
This control is executed to increase or decrease the feed speed without stopping paper at the
registration position to shorten the paper interval and improve productivity.
Stop Registration Control
This control is executed to stop paper at the registration position and restart feeding in
accordance with the timing when the image reaches the secondary transfer processing.
