Figure 83. Remove the intake fan

CAUTIONThe fan must draw air into the scan unit. Failure to correctly position the fan can result in damage to MFP components. Verify that the airflow arrow (located under the drive-belt tension bracket) embossed on the fan housing points into the scan unit. Verify that the optic-unit drive belt tension bracket (which sits on top of the fan) seats into the slot provided. See figure 84 on page 107.

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