[Function]
Enter the simulation code, and warm-up is started and warm-up time is counted for every sec-
ond from 0 and displayed.
When [Clear All] key is pressed during counting up, "0" is displayed on the display and counting
is stopped. However, warm-up is continued.
After completion of warm-up, counting is terminated. (The aging function is removed from simu-
lation 7-01.)
[Operation] (AL-2050/2060)
1) Initial display
07-08 W-UP C-MODE
[Function]
When [OK]/[START] key is pressed, the developing bias signal is turned ON for 30sec.
When, however, an actual output value is measured, use simulation 25-01.
After completion of this process, the machine goes into the sub code entry standby mode.
[Operation] (AL-2050/2060)
1) Initial display
08-01 DVLP BIAS SET.
EXECUTING...
[Function]
When [OK]/[START] key is pressed, the main charger is outputted for 30sec in the grid voltage
HIGH move.
After completion of this process, the machine goes into the sub code entry standby mode.
[Operation] (AL-2050/2060)
1) Initial display
08-02 MHV(H) SET.
EXECUTING...
[Function]
When [OK]/[START] key is pressed, the main charger is outputted for 30sec in the grid voltage
LOW move.
After completion of this process, the machine goes into the sub code entry standby mode.
[Operation] (AL-2050/2060)
1) Initial display
08-03 MHV(L) SET.
EXECUTING...
[Function]
When [OK]/[START] key is pressed, the transfer charger is outputted for 30sec.
After completion of this process, the machine goes into the sub code entry standby mode.
[Operation] (AL-2050/2060)
1) Initial display
08-06 THV SET.
EXECUTING...
[Function]
Use the duplex motor Bios to drive the duplex motor in the normal direction (paper exit direc-
tion) for 30sec.
After completion of this process, the machine goes into the sub code entry standby mode.
[Operation] (AL-2050/2060)
1) Initial display
09-01 DPLX ROT.
EXECUTING...
[Function]
Use the duplex motor Bios to drive the duplex motor in the reverse direction for 30sec.
After completion of this process, the machine goes into the sub code entry standby mode.
[Operation] (AL-2050/2060)
1) Initial display
09-02 DPLX ROT.REV.
