Item Description
Auto Focus System • After the initial focus adjustment, the auto-focus system will
adjust for the difference in the slide position from slide to
slide. This focus adjustment will occur within 1 second after
the slide is inserted into the GATE.
• The focus adjustment variation should not change from the
focus and reverse specifications by more than 3 times the
focus and reverse specifications.
Reliability The projector can operate for 2000 hours or 2,000,000 cycles.
The projector has a MTBF (mean time between failures) of 7500
operation hours.
Maintenance Preventive maintenance by a qualified service person is
recommended every 1500 hours of operation, or after 1 year.

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.
3. Check for a bind in the DIRECTION LEVER
ASSEMBLY.
4. Check that theDIRECTIONLEVERLINKis
in the correct position.
SLIDE TRAY does not rotate freely when the
SELECT BUTTON is pressed down. The
projector has power.
1. Press and release the SELECT BUTTON.
• Check that the LOCATOR LEVER
moves correctly and is not bent.
2. Press and hold the SELECT BUTTON
down.
• Check the SLIDE LIFT LEVER RAMP
for damage.
3. 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.

Malfunction 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.
3. Energizethe projectorand movetheTIMER
