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)

2. Operator Panel Assembly (Contains the OKIFAX 5050 logo) P/N 55083210

P/N 55083101

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.

Service Procedures

When servicing the OKIFAX 5050, refer to the maintenance procedures for the OKIFAX 5300 in the OKIFAX 5300/5600 Service Manual. The OKIFAX 5300 procedures apply to the OKIFAX 5050.

Application

This Flash firmware version is incorporated in first production release of the OKIFAX 5050.

Changes:

None (First Production Release)

Note:

The OKIFAX 5050 uses Flash ROM to store firmware and configuration changes. These ROMS are not socketed, and cannot be physically replaced. The Flash ROM version is field upgradable using two methods:

Replace the OKIFAX 5050 Main Control PCB (E17-3 PCB, part number 55083101). Replacement

boards should always contain the current version firmware.

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.

fax onto the received pages. TSI is printed at the leading edge of first reproduced copy. (Set at receiver.) When TF04 is set to "ALL", TSI is printed for the all received pages. ON : Enable OFF : Disable (Reference) TSI; Transmitting Subscriber Identification

06 No-toner memory

reception

Enables or disables the memory reception when the fax is in no toner condition. ON : The messages are printed when toner has been newly supplied or an operator performs the memory operation (OT10). OFF : The messages are printed in the print mode. But print quality is not guaranteed.

07 TAD mode For an external telephone answering device. Allows

the OKIFAX to share a telephone line with an answering device. If the REMOTE RX Function is set to a value other than OFF, that conde can be used to force FAX RX during TAD MODE. TAD mode is of two types (TYPE1/TYPE2). OFF/TYPE1/TYPE2 selectable. TYPE1

1. RING comes.

2. The TAD answers, returns the recorded voice message in TAD to calling party.

3. The FAX machine will continue to detect CNG signal while TAD works.

4. If the FAX machine detects CNG signal, the fax will go into normal receiving mode.

5. Even though the fax does not detect CNG signal, the fax will go to receiving mode in hook-on condition. TYPE2 The function from No. 1 to No. 4 of upper TYPE2 are the same as TYPE1.

5. If the fax does not detect CNG signal during working of TAD, the machine will go to standby mode.

08 Real time dialing Enables or disables the real time dialing. 3 types

selectable. (OFF/TYPE1/TYPE2) TYPE1: Real-time dialing is available when the optional telephone handset is OFF-HOOK. TYPE2: Real-time dialing is available when the optional telephone handset is OFF-HOOK or HOOK key is pressed.

09 TEL/FAX switching Enables or disables the TEl/FAX automatic switching.

month/day/year to day/month/year or vice versa. MDY/DMY selectable.

11 Long document SCAN Switches the function of transmitting long-size

document (more than 380 mm). ON : Unlimited (1 Hour) OFF : 380 mm. (14.96 inches)

12 Echo Protection Enables Echo Suppression for poor lines with echo,

usually during overseas transmissions. This bit setting controls the following features. ON: Enables OFF: Disables

MDY

OFF

13 MH only Switches the function of limiting image compression

only to the MH codes. This affects all communications, and should only be used as a last resort. ON : Coding scheme is MH only. When the receiving image data is affected by noise on the telephone line. OFF : Any of MH, MR and MMR.

14 High-speed modem

rate

Specifies the modem's starting speed, 33.6K, 28.8K,

14.4k, 9.6k, or 4.8kbps.

Note:

The following protocol is added to OKIFAX 5600: ITU-T standard V.34 for 33.6K or 28.8 kbps operation.

15 T1 (TX), timeout value Registers the time duration (in seconds) for which the

fax waits for the remote station's answer. This timer starts when the last dialed digit has been sent in the automatic transmission mode. * Selects the 3 digit timer 010 to 255 sec (in one second steps)

16 T1 (RX), timeout value T1 (RX), timeout value (later) Registers the time

duration (in seconds) for which the fax waits for the remote station's answer. This timer starts after the DIS is transmitted, and checked this timer by the transmission timing signal. If T1 times out, the fax disconnects the line. * Selects the 3 digit timer 010 to 255 sec (in one second steps)

17 T2, timeout value T2, timeout value (layer) Registers the time duration

(in seconds) for which the fax detects the EOL interval during reception of phase C. The fax disconnects the line when EOL can not detect within T2 timer. * Selects the 3 digit timer 001 to 255 selectable. (in 100ms steps) For example: 060 x 100 ms =6 s

18 DIS bit 32 Specifies whether to transmit a bit 32 in DIS. ON :

Transmits a bit 32 OFF: Disable

Note:

Disable only if communication / compatibility

problems occur with an older remote machine.

19 Error criterion Registers the threshold value whether to transmit

RTN or MCF signal when the error occurs in received data. 00% to 99% selectable. (in one percent steps)

20 Off-hook bypass Allows two OKIFAX machines to be connected

back-to-back for testing purposes. ON : Enable OFF: Disable

21 NL equalizer Selects equalization for the following cable lengths:

0 km/1.8 km/3.6 km/ 7.2 km selectable.

Note:

Relative to 1700Hz for length of 0.4mm

diameter cable.

22 Modem attenuator Adjusts the attenuation (dB) for the transmit signal

power level. Adjusting value is 0 to 15 dB in one dB steps. Since the maximum send signal power level (dB) of the fax is at 0 dB, you can select 0 dB to -15 dB in one dB steps for the send signal power level. 0 to 15 dB. selectable

23 T/F tone attenuator (for

TEL/ FAX SW)

Adjusts the attenuation (dB) for the quasi-ring back tone send signal of TEL/FAX switching. Adjusting value is 0 to 15 dB in one dB steps.

24 MF attenuator Adjusts the attenuation (dB) for the send MF tone

power level. Adjusting value is 0 to 15 dB in one dB steps.

25 Ring duration detection

time

Selects the minimum ring detection time Adjusting time is 100 MS to 990 MS in 10 MS steps. 10 to 99 selectable. For example: (120 ms) 12 x 10 ms = 120 ms

26 CML timing Selects the time from end of ring to CML-ON.

Adjusting time is 100 MS to 1900 MS in 100 MS steps. 0 to 19 selectable. For example: (300 ms) 03 x 100 ms = 300 ms

27 Strobe for LED head Setting of LED print head strobe signals

(00000-11111). Selection of strobe width in LED head. "00000" is darkest and "11111" is lightest. This setting should be verified upon initial install of machine, or replacement of main control board or LED Head.

Note 1:

When the rank marking of the new replaced LED print head (new part) is same as that of the old used LED print head (old part), you do not always have to set the LED print head strobe signal.

Note 2:

Intensity ranking is determined by the 1st, 2nd and 3rd digits from the right on the LED print head serial number. (i.e.: 212, 212 is the intensity ranking.)
