Cleaning Page (Phaser 840 printer only)
Under certain conditions, the printer purges its ink-jet nozzles to clear any jets
plugged with ink. When the purge is completed, the printer outputs a cleaning
page to clear the purge pattern from the print drum. Ink jets are purged under the
following conditions:
■
During warm-up from a power-off condition.
■
When the printer exits the Energy Star mode.
■
When customers initiate the

automatic
cleaning procedure from the front panel.
Vacuum
Vacuum dust from the top cover, the metal heat duct over the printhead and
plastic dust cover under the stripper fingers or rapid release guide.
Drum temperature sensor
With a dry swab, clean any buildup around the drum temperature sensor. You
can access the sensor through the opened exit cover. Also make sure the sensor
rides evenly on the drum surface. You can remove the sensor, if necessary, to
clean under it.
