HP 4101mfp manual Optical-unit drive-belt tension bracket

Reinstall Note Anytime the glass is removed and replaced, calibrate the ADF/scan unit. See “Calibration” on page 47.

Reinstall Note With the optical unit installed, place the optical-unit drive-belt onto the drive and tension gears. Verify that the drive-belt teeth face inward and are engaged with the gear teeth.

Position the bracket with the locator pins in the provided holes on the bracket, and tighten the screw until it holds the bracket in place but still allows the bracket to move.

Verify that the bracket is correctly positioned on the locator pins, and fully tighten the screw.
