WSW No. WSW38 WSW39 WSW40 WSW41 WSW42 WSW43 WSW44 WSW45 WSW46 WSW47 WSW48 WSW49 WSW50 Firmware Switches (WSW01 through WSW50) Continued Function Function setting 16 Function setting 17 Function setting 18 Function setting 19 Function setting 20 Function setting 21 Speeding up scanning-1 Speeding up scanning-2 Monitor of power ON/OFF state and parallel port kept at high Delay of FAX line disconnection Not used. Not used. Not used. n Operating Procedure (1) Press the 1 and 0 keys in this order in the initial stage of the maintenance mode. The machine displays the "WSW00" on the LCD and becomes ready to accept a firmware switch number. (2) Enter the desired number from the firmware switch numbers (01 through 50). The following appears on the LCD: Selector 1 Selector 8 ↓ ↓ WSWXX = 0 0 0 0 0 0 0 0 (3) For machines w/ fax: Use the and keys to move the cursor to the selector position to be modified. For machines w/o fax: Use the Reset key to move the cursor to the selector position to be modified. (4) Enter the desired number using the 0 and 1 keys. (5) For machines w/ fax: Press the Set key. For machines w/o fax: Press the Menu key. This operation saves the newly entered selector values onto the EEPROM and readies the machine for accepting a firmware switch number. (6) Repeat steps (2) through (5) until the modification for the desired firmware switches is completed. (7) Press the Stop key to return the machine to the initial stage of the maintenance mode. NOTES: • To cancel this operation and return the machine to the initial stage of the maintenance mode during the above procedure, press the Stop key. • If there is a pause of more than one minute after a single-digit number is entered for double-digit firmware switch numbers, the machine will automatically return to the initial stage of the maintenance mode. n Details of Firmware Switches The details of the firmware switches are described in Appendix 2 in which the user-accessible selectors of the firmware switches are shaded.

Operating Procedure

(1)

Press the

and

keys in this order in the initial stage of the maintenance mode.

The machine displays the "WSW00" on the LCD and becomes ready to accept a firmware

switch number.

(2)

Enter the desired number from the firmware switch numbers (01 through 50).

The following appears on the LCD:

Selector 1

Selector 8

↓

WSWXX =

0 0 0 0 0 0 0 0

(3)

For machines w/ fax:

Use the

and

keys to move the cursor to the selector position to

be modified.

For machines w/o fax:

Use the

Reset

key to move the cursor to the selector position to be

modified.

(4)

Enter the desired number using the

and

keys.

(5)

For machines w/ fax:

Press the

Set

key.

For machines w/o fax:

Press the

key.

This operation saves the newly entered selector values onto the EEPROM and readies the

machine for accepting a firmware switch number.

(6)

Repeat steps (2) through (5) until the modification for the desired firmware switches is

completed.

(7)

Press the

Stop

key to return the machine to the initial stage of the maintenance mode.

NOTES:

•

To cancel this operation and return the machine to the initial stage of the maintenance

mode during the above procedure, press the

Stop

key.

•

If there is a pause of more than one minute after a single-digit number is entered for

double-digit firmware switch numbers, the machine will automatically return to the

initial stage of the maintenance mode.

Details of Firmware Switches

The details of the firmware switches are described in Appendix 2 in which the user-accessible

selectors of the firmware switches are shaded.
