• Detecting the paper level
The lift rises as paper in the deck is used. When the remaining number of sheets in either right or left cassette reduces to
around 100 to 250 sheets, the projection on the lift belt assembly pushes against the sensor lever which turns the relevant
paper level detection sensor 1 or 2 (PLDSENS1/2) on.
When both paper level detection sensors 1 and 2 (PLDSENS1, 2) have turned on, the message “Low on paper.” is shown on
the copier message display. This message is not shown when only one of them is on.
As more copies are made with the message on, paper path sensors 1, 2 and 3 (PPSENS1, 2, 3) or the paper empty sensor
(PESENS) start to detect absence of paper, and the message “Place paper in deck.” is shown.
