2. Check for damage to parts.
3. Check for a short•circuit in the wires:
• Use a tool to hold the CYCLE LEVER
down on the RATCHET LEVER. If
there is a short•circuit causing the
malfunction, the SOLENOID will be
energized. If there is a bind, the CAM
will not rotate.
4. Check that the CAM SHAFT ASSEMBLY
RATCHET SPRING is installed correctly.
5. If there is a bind in the CAM STACK, install
a new CAM.

ASSEMBLY is in the correct alignment
with the holes at positions A and B.
• Do the adjustment for the INDEXER
LEVER ASSEMBLY.
• Check the condition of the LOCATOR
LEVER, it should not be bent.
• Check the height of the SLIDE LIFT
LEVER; the lower corner of the LIFT
LEVER RAMP is parallel with the TOP
HOUSING. If the height is not correct,
do the adjustment for the MANUAL and
POWER SLIDE LIFT LEVER
ECCENTRICS.
SLIDE TRAY advances when “REVERSE” is
pressed.
1. Do the adjustment for the CYCLE
SOLENOID.
2. Check that the SPRING is on the
DIRECTION LEVER.

Check
TIMER does not operate
1. Check the VARIABLE RESISTOR for
correct operation and install a new part if
necessary.
2. Move the TIMER BUTTON forward and
backward; use a DVM to check for changes
in W.

DARK SHUTTER to allow projection.
2. Check for continuity between PINS 4 and 5
on the SPECIAL APPLICATIONS PLUG.
3. Press the “FORWARD” or “REVERSE”
BUTTONS to close the DARK SHUTTER.
4. In the closed position, the DVM should
measure 0 W.
5. If this procedure does not correct the
malfunction, install a new DARK SHUTTER
SWITCH.
ZERO POSITION SWITCH does not operate
1. Deenergize the projector.
2. Check for continuity between PINS 1 and 3
on the SPECIAL APPLICATIONS PLUG.
3. Install a SLIDE TRAY.
4. Rotate the SLIDE TRAY to engage the
ZERO POSITION SWITCH, the DVM
should measure 0 W.
5. If the W measurement is not correct, see
the adjustment for the ZERO POSITION
SWITCH. Install a new ZERO POSITION
SWITCH if necessary.
After the FOCUS MOTOR energizes and
moves, the FOCUS MOTOR oscillates.
