1.6 Automatic Paper Loading, Switching, and Tearing-Off
Paper handling is automated as follows:
Paper is loaded or unloaded automatically using the LOAD button on the control panel. The print position can
be adjusted for each paper type and path beforehand in setup mode.
Cut sheets can be used without removing continuous forms currently loaded. Pressing the LOAD button moves
the loaded continuous forms from the platen to the parking position (forms tractor). After pressing the PAPER
PATH button so as to turn on the CUT SHEET indicator, pressing the LOAD button loads a cut sheet up to the
platen. After the cut sheet is printed, pressing the PAPER PATH button so as to turn on the FRONT TRACTOR
or REAR TRACTOR indicator and pressing the LOAD button reloads the continuous forms from the parking
position.
There is no waste of paper in tearing off the continuous forms printed. Pressing the TEAR OFF button on the
control panel positions the bottom perforation of the last printed page at the tear-off edge provided at the front
cover or upper cover of the printer. After tearing off the last page, pressing any button backs the new first page
to the print position. This back-and-forth feeding is called tear-off feeding. Tear-off feeding saves pages.
Automatic tear-off feeding can be specified in setup mode; the printer waits for a while between jobs instead of
requiring the TEAR OFF button to be pressed. If a job ends and no data is sent from the computer, the printer
automatically feeds the last page to the tear-off edge.
