Missing print emitter pulses - A print emitter pulse was not found
(continued) during the specified time (150
ms
-
SO
cps, 100 ms - 120 cps).
(
The print head stepper
motor
begins turning when
it
receives
pulses from the printer adapter. Error checking begins when the
print head stepper motor is up
to
speed.
If
a print emitter pulse
does not occur during the 100 ms or 150 ms timing, a 057 error
occurs.
If
a print emitter pulse does occur but is
not
the expected
(
pulse, a 056 error occurs. Refer
to
Print Emitter Error Timing
following these error codes.
Failures that prevent the carrier from moving (broken belt) cause a
057 error. Light mechanical binds or print emitter failure usually
cause a 056 error.
