1.1 FAX UNIT

1.1.1 CAUTIONS

NOTE: 1) Never install telephone wiring during a lightning storm.

2)Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.

3)Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.

4)Use caution when installing or modifying telephone lines.

5)Avoid using a telephone (other than a cordless type) during an electrical storm. There may be a remote risk of electric shock from lightning.

6)If there is a gas leak, do not use the telephone in the vicinity of the leak to report it.

!CAUTION

1.Before installing the fax unit, switch off the main power and operation switches, and disconnect the power cord.

2.The fax unit contains a lithium battery. The danger of explosion exists if a battery of this type is incorrectly replaced. Replace only with the same or an equivalent type recommended by the manufacturer. Discard used batteries in accordance with the manufacturer’s instructions.

ERROR CODES FOR THE ISDN OPTION

2.2 ERROR CODES FOR THE ISDN OPTION

The tables on the following pages show the error codes for the ISDN option. The meaning of the numbers in the Action column is as follows.

1.Check Layer 1 signaling with a protocol analyzer to determine the cause of the problem. This may require assistance from a G4 specialist.

2.Repeat the communication. If the problem does not repeat itself, the problem was a temporary one caused by the user connecting the machine to another interface. However, if the problem remains, there is a network problem.

3.There is a network problem.

4.There is a network problem. Do the following:

•Check the error bit rate of the network. If it is high, contact the network and ask them to improve the line.

•Check the network speed (is it 56 or 64 kbps), and make sure that the bit switch setting is correct. You may also use the dedicated transmission parameters if this problem only occurs when dialing certain numbers.

•Check that the user dialed the correct number.

5.There is a network problem, or a problem in the machine at the other end.

6.There is a problem in the machine at the other end; ask a technician to check it.

7.The machine at the other end is not a Group 4 fax terminal.

8.The machine is not compatible with the machine at the other end. A compatibility test is needed.

Error codes related to the errors detected by the FCU are listed in the service manual of the main body.

FAX SC CODES

2.3 FAX SC CODES

2.3.1 OVERVIEW

When the FCU detects a Fax SC Code condition other than SC1201 and SC1207, it resets itself automatically (default setting). This initializes the FCU without erasing files in the SAF memory or resetting the switches.

NOTE: For details on Fax SC Codes 1201 and 1207, refer to the following sections.

If bit 7 of System Switch 1F is changed to “1”, when the FCU detects a Fax SC Code condition, it displays the code on the display and stops working until the fax unit is initialized using one of the following methods:

•Hold down the “#” and “*” keys for more than 10 s.

•Turn off the main power switch and turn it back on.

2.3.2 SC1201

When the FCU detects an unrecoverable error in the SRAM, which requires a complete SRAM initialization, the fax unit displays this SC Code and stops. There is no way to recover from this error condition without a complete SRAM initialization (all the user and service programmed data will be erased).

The possible causes are:

•SRAM backup battery defect, or SW1 on the FCU is at the “OFF” position

•SRAM on the FCU has a physical defect

•Flash memory card or data copy tool connection was loose

2.3.3 SC1207

This is the same as SC1201 except the error location is the SRAM on the Fax Function Upgrade board.

The possible causes are:

•SRAM backup battery defect, or SW1 on the Fax Function Upgrade board is at the “OFF” position.

•SRAM on the Fax Function Upgrade board has a physical defect.

•The Fax Function Upgrade board connection was loose.
