SETUP

Note:
• When the ISW is carried out to make a USB con-
nection, this step should be omitted.
7. Execute the operation according to the proce-
dures specified in the “ISW (In-System Writer)
Service Manual.”
8. In about 60 seconds after the data transfer from
the PC has been completed, the ISW data is
written from the system memory in the SCB
(System control board) into the flash ROM in
which data is stored.
Note:
When Steps 4 and 5 are not carried out to make a
USB connection, the USB port is not opened and
the data cannot be sent from the PC. When the
normal operation of the ISW is not available, start
all over again from Step 1 after turning the SW1
(main switch) OFF and ON.
Be sure not turn off the power to the copying
machine while the ISW data is being written.
9. When data has been written into the flash ROM,
the system is restarted to display the “25 mode
menu screen.”
(2) When the overall control program is not
installed
1. Turn on the SW1 (Main power switch) and the
SW2 (Sub-power switch).
2. Check to see if the data LED indicator lamp is
on. In this condition, the ISW is placed in waiting
for transfer.
Check to see if the data LED is flashing while
the ISW data is being received.
3. The procedure after this is the same as the
steps above for “(1) When the overall control
program has been installed”.
F. Data transfer error
When a transfer error occurs, an error mark is
displayed in the message area on the LCD dis-
play.
If an error occurs, see the section “Error han-
dling” in the separate “ISW Service Manual”
and perform the appropriate countermeasures.
After the countermeasures are completed, per-
form the re-write operation again from the
beginning.
