2.4.5 JAM RECOVERY
If the jam recovery feature is on and a paper jam occurs, the controller will reprint
all pages for which a feed-out indication has not been received from the main
machine. In usual cases, all image data from the controller will be sent to the hard
disk on the main machine, When a jam occurs, the recovery data will be sent from
the hard disk on the main machine.
2.4.6 AUTO TRAY SELECT
When “Auto Select” is selected with the printer driver, the printer searches for a
tray that contains the specified size of normal plain paper. The search starts from
the LCT, and when a tray that contains the specified size of paper is found, the
printer starts printing and feeds paper from that tray. The search sequence is as
follows.
LCT – 1st tray – 2nd tray – 3rd tray – 4th tray – LCT
The default setting for the current tray is LCT. If the LCT is not installed, the default
is the 1st tray.

When the controller is turned on, it performs a self diagnostic sequence of tests
automatically. If any errors were detected, an error message will be displayed on
the operation panel.
