Service Manual for OF5300/5600
Chapter 0 Introduction
Functionality
The OKIFAX 5050 is technically similar to the OKIFAX 5300. The physical appearance is identical to the
OKIFAX 5300; however, the OKIFAX 5050 is strictly a stand-alone facsimile product. Although there is a
PC Interface connection socket on the OKIFAX 5050's Main Control Board, this socket is not functional,
and the PC Interface cannot be used on this product. This socket will only be used to update Flash ROM
using the High Speed Loading System.
In addition, the OKIFAX 5050 will only accept the 1.5 MB Memory Option (with battery back-up), and the 1
MB Memory Option (without battery back-up). Other than the lack of PC Interface and optional memory
capability, there are no other functional or operational differences between the OKIFAX 5050 and the
OKIFAX 5300.
Hardware
There are two hardware (spare part) differences between the OKIFAX 5050 and OKIFAX 5300. The
following parts are unique to the OKIFAX 5050:
1. Main Control PCB (E17-3 PCB) P/N 55083101
2. Operator Panel Assembly (Contains the OKIFAX 5050 logo) P/N 55083210
Firmware
For First Production Release Firmware Information, refer to Product Bulletin # E708 (on the back of this
sheet).
Standard Memory
The OKIFAX 5050 has 256kb of standard document storage memory.

two methods:
1. Replace the OKIFAX 5050 Main Control PCB (E17-3 PCB, part number 55083101). Replacement
boards should always contain the current version firmware.
2. Use the Remote Management Center System (RMCS) to upgrade Flash ROM remotely via the
telephone. The "RMCS" is a remote diagnostic system, that may be purchased by authorized
OKIDATA dealers that allows remote programming and diagnosis of OKIFAX machines via
telephone. The OKIFAX 5050's Flash Firmware can also be updated remotely using this tool. For
more information regarding the availability and/or purchase of an OKIFAX RMCS system, please
contact your OKIDATA Sales Representative.
