AR-5520 SIMULATIONS 7-13
43 13 Fusing paper interval control allow/
inhibit setting Used to set the paper feed timing of 21st and later page to A3 or W LT when multi copying or printing
paper of narrow width. (A3 or W LT depends on the destination.)
W hen this simulation is executed, the currently set code number is displayed. Enter a desired code
number and press the [START] key, and the entered code number is written into the EEPROM and
the machine goes into the sub code entry standby mode.
<Applicable paper>
1) Paper tray: A4R, B5R, 8-1/2" X 14", 8-1/2" X 13", 8-1/2" X 11", A5, INV
2) Bypass tray: A4R, B5R, 8-1/2" X 14", 8-1/2" X 13", 8-1/2" X 11", A5, INV,16KR
*
A5 size for bypass tray is valid only for EX Japan AB series.
44 01 Toner density control Enable/
Disable (ON/OFF) setting Setting is made whether the toner density control is performed or not.
W hen this simulation is executed, the current code number is displayed on the 7-seg display. (1=ON
[Enable], 0=OFF [Disable])
Enter a code number and press [START] key, and the setting is settled and saved into the EEPROM
and the machine goes into the sub code input standby mode.
Switching can be made with [AUTO/TEXT/PHOTO] key, and the set value of the selected mode is
displayed on the copy quantity display section.
The entered value at that time is written into the EEPROM.
<Descriptions on each correction>
Print ratio correction
In this correction, the toner supply interval is determined according to the print ratio, and an
overtoner is prevented.
Life correction
W hen the life of any consumable part approached the end, this correction prevents against
undertoner.
Note for items marked with
Drip infusion and Purge process are simulations for analysis, and do not set them to "Enable=1" in
the market.
If these items are set to "Enable=1", the toner density rises or falls extremely, resulting in developer
fall and toner dispersion.
If they are set to "Enable=1", developer must be replaced and the machine inside and the process
unit must be cleaned.
Unconditional toner supply
W hen the DV unit and the drum unit run idle, a small quantity of toner is consumed. To supply this
consumption, toner is supplied according to the rotation time of the DV unit.
16 Toner density control data check
and toner density control
correction amount display The output value of the ATC sensor is checked and the toner density control correction value is
displayed on the 7-seg display.
The display mode can be switched by pressing [AUTO/TEXT/PHOTO] key.
W hen [Interrupt] key is pressed, the machine goes into the sub code input standby mode. W hen [CA]
key is pressed, the machine goes out of the simulation mode.
