P/H Control Mode
Yes
Sensed Printhead
temperature is 55° to
59°C causes a 50%
reduction in print speed.
This mode dramatically
extends the time before a
PRINT HEAD HOT fault
would occur and permits
long print jobs to
complete without
interruption. Printing
stays in this mode until
head temperature drops
below 52°C where full
speed printing resumes,
or until head temperature
reaches 60°C where
printing stops with a
PRINT HEAD HOT fault
message displayed.
This is a printer protection
feature, but the time before the
printer reaches the P/H Control
Mode may be extended by:
1. Placing the printer in a cooler
temperature environment.
2. Cleaning the printhead more
frequently between jobs.
3. Reducing the Print Speed.
4. Reducing the print intensity.
5. Extending the idle time
between print jobs.
6. Reducing the amount of black
image density per print job.
7. If problem persists, contact
your authorized service
repersentative.
