Oki OKIFAX 5750 Maintenance Manual page 754

2.3.1 Operating Conditions
1. Option board PC loading is started when the following operation is performed with a
Option board installed in the OKIFAX5750/5950 main unit:
- Operation of option board PC loading key when the OKIFAX5750/5950 is in the normal
standby state
Unlike the PC loading to the MCNT, there is no other methods for starting loading such as
the method by which a special operation is performed. (For details on the key operation,
see Section 2.2.1.3, "Operation Flow.")
2. Since the option board PC loading function is performed using the program in the flash
memory in the OKIFAX5750/5950 main unit, option board PC loading cannot be done
when the machine does not start normally due to a flash memory hash error. (It is a
matter of course that option board PC loading can be performed normally even if a flash
memory hash error occurs on the option board side.)
3. The PC has no dedicated application for option board PC loading. Use a COPY com-
mand of MS(PC)-DOS along with a binary switch (copy/b) to output option board PC
loading data through the parallel port.
4. When option board PC loading ends normally, control jumps to the initial process, getting
into the normal standby state.
5. When an error such as a hash error occurs, its cause is displayed on the LCD. For error
codes, see Chapter 6, "Error Causes and Codes."
