6.7.4 PAPER END, TRAILING EDGE DETECTION
There is no mechanism to detect paper end in the paper cassette or the paper feed
unit.
A feeler [A] rises when a sheet of paper gets fed. This turns the trailing edge
sensor [B] on. After the sheet passes, the feeler drops and the trailing edge sensor
goes off.
A paper end error shows at these times:
• The paper feed roller rotates forward twice (once to feed the sheet, and again to
try feeding the sheet again).
• The trailing edge sensor does not go on after 2 rotations of the paper feed roller.
The length of time the trailing edge sensor stays on is also used to detect the
length of the paper for printing control.
