3.3 Detection of Abnormal Status
3.3.1 Cover open/Close detection
When the PFU cover open switch detects the open state of the cover, the copier detects it to stop the
transport of paper.
3.3.2 Paper empty detection
When there is no paper in the cassette tray or the PFU paper empty sensor detects the absence of paper
during printing, the operation is stopped. The absence of paper is detected only when the cassette is
closed.
3.3.3 Paper jam detection
The PFU itself has no feed sensor but installation of the PFU allows the sensor (2nd cassette feed sensor)
on the copier side to be effective. When transporting the paper, if the 2nd cassette feed sensor does not
detect the passing of paper or the paper is left detected for a fixed time, the program will judge it to be paper
jamming and stop the operation. The error state is reset by opening and then closing the cover.
3.3.4 Tray-up motor failure
If no paper is detected or the tray-up upper limit is not reached even if a specified amount of time has
elapsed after the cassette is mounted, a tray-up motor failure will be assumed. To reset the error state,
once draw out the cassette.
