Mechanical adjustments
To adjust the ADF height
The height of the ADF is adjusted by lengthening or shortening the left and right adjusting bolts (callout 1) so that the distance between the two rubber feet (callout 2) at the rear and the horizontal size plate (callout 3) on the copyboard glass (callout 4) is 0.2±0.1 mm (the thickness of two sheets of 64 g/m2 copy paper) when the ADF (callout 5) is closed, and the feet (callout 6) at the front are in contact with the copyboard glass. To adjust the ADF height, follow these steps: 1 2 Turn the copier off. Remove the ADF to expose the adjusting bolts. (See �Removing the ADF� on page 378.)

After adjustment, check to make sure that both the left and right rubber feet at the front of the ADF are in contact with the copyboard glass. If not, adjust the height of the magnet at the front of the ADF.
