adjusted as follows:
<Adjustment Mode (05)>
Code
7000 PPC
7001 PRT(*1)/FAX
*1: This adjustment is not available for the printer function when the resolution of the
image is 600 x 1200 dpi.
Make a test copy and compare the image obtained with the current settings; if necessary,
make adjustments according to the following procedure:
Notes:
• Since the reproduction ratio may vary due to expansion and contraction of the paper
immediately after the image is printed out, it is recommended to measure its dimension
after at least 3 minutes have passed.
• This adjustment may cause image troubles such as moire, disappearance or breaking
of thin lines on the printed image. Therefore check if there is no such image trouble
while you are performing the adjustment.

(2) Key in a code and press the [START] button.
(3) Key in the adjustment value. (To correct a value, press the [CLEAR] button.)
(4) Press the [OK] or [INTERRUPT] button to store the value. -> The equipment goes back
to the ready state.
(5) Make a test copy and check the image copied. To check the printed image, turn off the
power and then back on, and then print the image. If the image is not in the desired
reproduction ratio, repeat steps (2) to (4).
