Activators Tray 5 Pick Clutch
(cont.) This test briefly energizes the
Tray 5 Pick Clutch and mea-
sures parameters. Peak
power is expected to be very
close to the average power
level. A change in heating
behavior could indicate a
problem with cooling or the
thermal conductivity through
the mounting.
Deskew Clutch
This test briefly energizes the
Deskew Clutch coil and mea-
sures parameters. Peak
power is expected to be very
close to the average power
level. A change in heating
behavior could indicate a
problem with cooling or the
thermal conductivity through
the mounting.
Strip Solenoid
This test briefly energizes the
Stripper Solenoid and mea-
sures parameters. Peak
power is expected to be very
close to the average power
level. A change in heating
behavior could indicate a
problem with cooling or the
thermal conductivity through
the mounting.
Head Maintenance Clutch
This test energizes the Head
Maintenance Clutch coil and
measures parameters. Peak
power is expected to be very
close to the average power
level. A change in heating
behavior could indicate a
problem with cooling or the
thermal conductivity through
the mounting.

Activators Purge Valve Solenoid
(cont.) This test energizes the Purge
Vent Solenoid and measures
parameters. Peak power is
expected to be very close to
the average power level. A
change in heating behavior
could indicate a problem with
cooling or the thermal con-
ductivity through the mount-
ing.
Preheater Solenoid
This test briefly separately
energizes both coils of the
Preheater Solenoid Assem-
bly and measures parame-
ters. Each Solenoid Coil is
activated for a short time a
both high and low power lev-
els while the power is mea-
sured to show that the
Solenoid Coils are indepen-
dently controllable and draws
the expected amount of
power.
Tilt Solenoid
This test energizes the Head
Tilt Solenoid Coil and mea-
sures parameters. The Sole-
noid is engaged at high
power and held at a lower
power. The on cycle is four
times longer than the other
activators. During the first
half of the on period, high
power is applied. The power
is dropped to low during the
second half of the period.
The Solenoid should not
release until the end of the
on period.
