AUTOFOCUS
AutoFocus is an optional accessory. It is a factory installation. It will be necessary to perform simple
field maintenance wth the following tools:
· #1 Phillips head screwdriver
· #2 Phillips head screwdriver
· (2) 7/16 open end wrenches (optimally with offset heads).
CRITICAL MAINTENANCE POINTS:
· Tighten all Phillips head screws as much as possible.
· Tighten the front guide bolt as much as possible.
· Verify that the lead screw is exiting the motor opening at center. Observe this with the scroller
attached and the lead screw positioned either all the way out or all the way in.
If the lead screw is not at the exact center of the motor opening, loosen the two jam nuts.
Then tighten or loosen the rear guide bolt so that the lead screw is centered in the motor
opening. Once positioned correctly, use one crescent wrench to hold the rear guide bolt in
place, and use the other one to tighten the two jam nuts.
· Verify that the home flag is perpendicular to the drive shaft and flat so that it passes through the
home sensor correctly. Carefully adjust as needed.
