Heaters This function allows each
Heater to be turned on or of.
The Printhead Heaters and
the Ink Melt Heaters are each
treated as a group. Auxiliary
function in this menu enable
the On/Off state and allo

cated power for each Heater
to be viewed, and also the
current temperature and set

point of the corresponding
thermal control loop. Exiting
the function leaves the Heat
-
ers in the final state selected.
Pressing any buttons on the
Control Panel will terminated
the monitoring.
The test tilts the Printhead
back to isolate the Drum from
the Jetstack Heaters. The
Drum is rotated at idle veloc
-
ity to keep the Drum temper-
ature uniform. The test then
sequentially applies power to
each Heater (while monitor
-
ing all of the temperatures),
to produce a temperature
response. The test deter
-
mines the relationship
between heating power
applied, the resulting temper
-
ature response profile, and
the current drawn by each
other.
