Reassemble the modules of the machine in reverse order and
mount them back into the machine. Turn the machine on and
make sure it enters into ready condition. Make a copy of the test
target designed to adjust the copy density. Make copies in all
exposure modes – Auto, Manual (middle position), Dark (max.
right position), Light (max left position) and Photo. If the copy
density in unsatisfactory you should make adjustments in the
following order.
IMAGE DENSITY ADJUSTMENTS
1. Enter the adjustment mode AJ by holding together numerical
buttons 0 and 5 and turning on the machine.
2. Begin with adjustment of the copy density in the middle
position. Make a test copy by pressing the "Energy saver
button". Change the value of code 1 if the copy is too light
or too dark (the higher the value the lighter the copy
density). The procedure is the following: enter 1 and press
the Start button. Change the value and store it by pressing
the Interrupt button. Make a test copy and readjust if
necessary.
3. Execute the auto exposure auto adjustment procedure – place
a couple of white A3 sheets on the original glass and close
the platen. Enter code 49 and press the start button. After
completion make a test copy. If necessary change manually
the auto exposure density by changing the value in code 5.
4. Adjust the density of darkest and lightest mode using the same
procedure as in 2. The codes are respectively 10 and 9.
5. Adjust the density of the photo exposure – code 14.
6. Exit the AJ mode by pressing the o and 9 buttons or turn off
