AR-M351U/M451U, AR-M355U/M455U SIMULATION 9 - 35
Operation/Procedure
Operation/Procedure
The output levels of the temperature thermistor and the humidity
thermistor in the developing unit are displayed.
Operation/Procedure
Operation/Procedure
1) Select the number corresponding to the copy mode to be
adjusted with 10-key. (Select one of 3 - 6.)
2) Press [START] key.
3) Enter the copy density level with 10-key.
4) Press P key or [START] key.
The adjustment value is set.
When [START] key is pressed, copying is performed and the
adjustment value is simultaneously set.
Check the density of the printed copy image.
NOTE: When the copy image density is adjusted with this simula-
tion, the copy image densities of all the copy modes are
changed to the copy image density level set with this simu-
lation.
That is, the copy image density of each copy mode set with
SIM 46-9, 10, 11 is changed to the copy image density
level adjusted with this simulation.
To select paper (paper feed tray), perform the following proce-
dures.
1) Enter 0 with 10-key.
2) Press [START] key. (The mode is changed to the paper feed
tray selection mode.)

Purpose Adjustment/Setup/Operation data output/Check
(Display/Print)
Function
(Purpose)
Used to check the data related to the image
forming section correction (process correction)
result (corrected main charger grid voltage, the
developing bias voltage, and the laser power
voltage in each print mode). (This simulation
allows to check that correction is performed
normally or not.)
