1.8.1.2 Paper Handling and Operations

Paper Loading and Ejection
Since the paper release lever is controlled automatically, the pApER SELECT and LOAD/EJECT switches
on the control panel provide highly improved paper handling. That is, change over between fanfold
(continuous) and single sheet paper and loading/ejecting paper are performed automatically.
a) Single Sheet Loading and Ejection
To load a sheet of paper, press the PAPER SELECT switch and select FRICTION feed. If fanfold paper
loaded, the paper is ejected backward (automatic back out). Place the page along the paper guide,
is
and press the LOAD/EJECT switch. This loads the paper at the top-of-form position. If the
LOAD/EJECT switch is pressed after paper has been loaded, it causes the paper to be ejected
forward.
b) Fanfold Paper Loading and Ejection (Back Out)
Set the fanfold paper into the push-tractor unit. To load fanfold paper, press the PAPER SELECT
switch and select TRACTOR feed. If single sheet paper is loaded, the paper is ejected forward and
the fanfold paper is loaded. When the TRACTOR feed has already been selected, pressing the
LOAD/EJECT switch loads the paper automatically to the top-of-form position. If LOAD\ EJECT
switch is pressed after the fanfold paper has been loaded, the printer ejects the paper backward
to the push tractor. To back out several pages, press the LOAD\ EJECT switch several times, since
reverse feed is performed on a page-by-page basis.
Micro Adjustment Function
In either case a) or b) above, the top-of-form position is adjustable using the MICRO FEED switch (the
message "TOF ADJUST" is displayed on the LCD, and the MICRO FEED, V, and A LEDs are lit.). Pressing
the FORM FEED switch advances the paper forward in increments ofl/1 80" continuously as long as
the switch is held down, and pressing the LINE FEED switch moves the paper in reverse in increments
of 1/180". Moving the paper with these switches is called micro adjustment. The adjusted position
is stored in the memory and remains effective at the next loading even if the power is cycled. But the
tractor feed is selected, the adjusted position is remained even if the power is turned off.
Auto-Tear-Off Function
To enable the auto-tear-off function, select AUTO TEAR OFF using the SelecType function. When this
function is activated and the PAPER SELECT is FRICTION, paper is fed in the following way: after the
input data buffer becomes empty, while the printer is ON-LINE, the printer feeds the paper so that the
perforation at the form's end is moved automatically to the tear-off edge of the printer cover. After the
printer has positioned the paper, the message "TEAR OFF ADJUST" is displayed on the LCD, and the
V,
and MICRO FEED LEDs are lit.

adjustment of the tear-off position. The adjusted position is stored in the memory and remains effective
at the next tear-off even if the power is turned off and on. If subsequent data is input to the printer,
the paper will be reversed to its original position automatically and printing will start. If the ON-LINE
switch is pressed (taking the printer OFF-LINE) while the paper is advanced to the tear-off position, then
the printer will reverse the paper to its original position. The manual tear-off function selected by the
TEAR OFF switch is also called a tear-off function.
The FORM FEED and LINE FEED switches are then available for micro
