Aligning the Headlift Sensor
Step Procedure
1 Close the Upper Imaging Assembly; leave the Top Cover open.
2 Apply power to the printer; press both the on-line and on/cancel buttons at the
same time. You will hear the Headlift motor energize for a moment and then
stop — it sounds like a low-pitched winding noise.
Positioning the Headlift Cam
Step Procedure
1 Examine the eccentric cam in the middle of the Headlift Shaft Assembly. The
cam is a black, semi-round cylinder ¾-inch wide positioned midway across the
width of the Upper Imaging Assembly, riding against the Cam Lift Plate and a
thin metal plate called a Cam Follower Spring.
2 Run the Headlift Alignment procedure above.
3 Watch the rotation of the eccentric cam.
• The eccentric cam will make one complete rotation (360°)
counterclockwise; it should come to rest with the fattest portion of the cam
face down, pushing the Cam Lift Plate to its lowest position.
• The lifter arm of the Headlift Switch should be depressed, opening the
contacts of the Headlift Switch. (It should be an open contact when
depressed; with the arm released the contacts will close.) The Headlift
Switch could be malfunctioning if the fat portion of the cam stops at the
highest point. Adjust the mounting screw of the Headlift Switch; it may be
too tight.
• Ensure that the switch is positioned correctly on the Print Assembly
Sideplate. Make sure the switch activates when the lifter arm is depressed.
This can be measured with an ohmmeter for continuity.
• Check the rotation of the cam during the Headlift Alignment procedure if
difficulty persists. Normally, the cam should rotate counterclockwise (from
the front of the printer).
• If the camis rotating clockwise, the HeadliftMotor cable connection (J15 on
the Print Circuit Board) is reversed.
