Explanation of Symbols
The following symbols are used throughout this Service Manual.
Symbols Explanation Symbols Explanation
Check. Remove the claw.
Check visually. Insert the claw.
Check the noise. Use the bundled part.
Disconnect the connector. Push the part.
Connect the connector. Plug the power cable.
Remove the cable/wire

The following rules apply throughout this Service Manual:
1. Each chapter contains sections explaining the purpose of specic functions and the
relationship between electrical and mechanical systems with reference to the timing of
operation.
In the diagrams,
represents the path of mechanical drive; where a signal name
accompanies the symbol, the arrow
indicates the direction of the electric
signal.
The expression "turn on the power" means ipping on the power switch, closing the
front door, and closing the delivery unit door, which results in supplying the machine with
power.
2. In the digital circuits, '1' is used to indicate that the voltage level of a given signal is
"High", while '0' is used to indicate "Low". (The voltage value, however, differs from
circuit to circuit.) In addition, the asterisk (*) as in "DRMD*" indicates that the DRMD
signal goes on when '0'.
In practically all cases, the internal mechanisms of a microprocessor cannot be checked
in the eld. Therefore, the operations of the microprocessors used in the machines
are not discussed: they are explained in terms of from sensors to the input of the DC
controller PCB and from the output of the DC controller PCB to the loads.
The descriptions in this Service Manual are subject to change without notice for product
improvement or other purposes, and major changes will be communicated in the form of
Service Information bulletins.
All service persons are expected to have a good understanding of the contents of this Service
Manual and all relevant Service Information bulletins and be able to identify and isolate faults
in the machine.

Overview
Guide to Error Code
When the Board has been installed and '1' is set for service data #1 SSSW SW01 bit 0,
communications ending in error will be indicated in the following reports using service error
codes: communications management report, reception result report, and error transmission
report.
You can also check the code of an error by making the following selections: System Monitor >
Fax > Detail.
The major error codes used by the Board are listed on the pages that follow. For information
on causes and remedies in connection with other error codes, see the "G3/G4 Facsimile Error
Code List" (HY8-23A0-020).
If the Board indicates a service error code, try the following:
- Increase the transmission level.
Set -8 (dBm) for service data #2 MENU parameter No. 007.
- Decrease the transmission level.
Set -15 (dBm) to service data #2 MENU parameter No. 007.
- Provide a remedy against echoes.
Change the following bit setting for service data #1 SSSW SW03:
Bit4 -> 1: to cause the machine to ignore the rst DIS signal from the other party.
-> 0: to cause the machine to ignore the rst DIS signal from the other party.
Bit5 -> 1: to cause the machine to transmit a tonal signal (1850 or 1650 Hz) in response to
the DIS signal from the other party.
-> 0: to cause the machine not to send a total signal (1850 or 1650 Hz) in response to
the DIS signal from the other party.
Bit6 -> 1: to cause the machine to send a 1850-Hz tonal signal if bit 5 is set to '1'.
-> 0: to cause the machine to send a 1650-Hz tonal signal if bit 5 is set to '1'.
Bit7 -> 1: to cause the machine to send a total signal before sending the CED signal.
-> 0: to causes the machine not to send a tonal signal before sending the CED signal.
- EPT (echo protect tone)
Change the setting of service data #1 SSSW SW03 bit 1:
Bit1 -> 1: to cause the machine to send EPT.
-> 0: to cause the machine not to send EPT.
- Adjust the NL equalizer.
Set '1' for serve data #2 MENU parameter No. 005.
- Decrease the transmission start speed.
Decrease the transmission start speed in user mode: System Settings > Communications
Settings > Fax Settings > Send Start Speed.
- Make the TCF evaluation standards lenient.
The Board does not offer a means by which to provide this remedy.
- Make the RTN transmissions conditions lenient.
Change parameters No. 2 through No. 004 of service data #3 NUMERIC Param.
No. 002: error rate for all lines; change it so that it is closer to 99%.
No. 003: number of lines in connection with bursts; change it so that it is closer to 99 lines.
No. 004: number of errors falling short of a specic number of lines in connection with
bursts; change it so that it is closer to 99.
- Increase the length of silence after reception of CFR.
Set '1' for service data #1 SSSW SW04 bit 4.
Bit4 -> 1: length of time during which a low-speed signal is ignored after transmission of
CFR; 1500 msec
-> 0: length of time during which a low-speed signal is ignored after transmission of
CFR; 700 msec
- <When using IPFAX> Change the mode of T.38 to "TCP".
Change "SIP TX Transport" to "TCP" in [Media (T.38) Settings].

The image transfer failed when transferring to the memory media because an
invalid character (such as \) was included in the specied lename.
#403
The job failed because a le with the same name already exists. Generally, if a le
with the same name exists, a number ranging from 1 to 999 is added to the tail of
the name to prevent naming conicts. However, this error occurred because a le
with the same number added to its le name already exists.

The address book is currently being imported/exported from the Remote UI, or the
machine is busy with other send related functions.
#711
