5.2.2.2 Retry Pickup

If the paper leading edge sensor (PS102) does not detect paper within a specific period of
time after the manual feed pickup roller starts to rotate, the machine will rotate the manual
feed pickup roller once again to execute a retry pickup operation. If the paper leading edge
sensor (PS102) still does not detect the leading edge of paper after the machine executes a
retry pickup operation once, the machine will identify the condition as a jam and will indi-
cate a jam message on the LCD.

5.2.2.3 Detecting the Size of Paper

The size of paper in the manual feed tray is detected using the paper leading edge sensor
(PS102) with reference to the length of paper. In fax mode, if paper of a size different from
the size selected from the control panel is placed, the DC controller will identify a paper size
mismatch at the end of printing and indicate a message on the LCD.
