6.5.1 Density adjustment
The center density and the density variation controlled by density adjustment keys can be adjusted as
follows.

should be a simple binary threshold adjustment.

(2) Key in a code and press the [START] button.
(3) Key in an adjustment value.
(To correct the value once keyed in, press the [CLEAR] button.)

The equipment goes back to the
ready state.

If possible, perform a Fax transmission and check the adjusted density with the image on the recipient's
side.
