In the case of a conditional stop, the print instruction is properly executed and then fol-
lowed by a logical interruption in the program sequence.
In the case of an unconditional stop
or complete shutdown, the print instruction may not be logically completed; i. e., the line may
not be completely printed.
3.
To perform a restart operation following a printer stop for a FORMS
indication:
a.
Determine the cause of the FORMS indication and make the
necessary corrections.
This indication is caused by an
interlock condition in the paper-feed mechanism resulting
from paper supply depletion or skewing of the form in the
tractors.
Tearing of the form in the tractors or improper
loading may also cause an interlock condition, thus yielding
a FORMS indication.
b.
Depress the TYPE ROLL ON button on the ITlain control panel
of the printer.
c.
Perform a normal head-of-form alignment procedure (see below).
d.
Depress the START button on the main control panel of the printer.
