Problems related to the copy function are described below. For problems related to general use of the machine, see

Problem Check Solution
Machine does not
operate. Is the [START] key indicator off? This indicates that the machine is warming
up (warming up lasts no more than 80
seconds after the power switch is turned on).
Copying is not possible during this time.
Wait until the [START] key light illuminates.
Copies are too dark
or too light. Is the original image too dark or too light? Select an appropriate exposure mode for
the original being copied and adjust the copy
exposure. (See page 4-14.)
Is the exposure mode set to "AUTO"? The exposure level for "AUTO" can be
adjusted using the "Exposure adjustment" in
the administrator settings. Contact your
administrator. (See page 16 of the
administrator settings guide.)
An appropriate exposure mode for the
original has not been selected. Change the exposure mode to "AUTO" or
manually select an appropriate resolution

original face down.
