19) Dial test mode
The mode is used to inspect whether dialing is accurate in two kinds of dial modes . All data which can be dialed in this mode are automatically called up in both DB mode and DP mode. When this mode is activated, the following operations will be automatically executed . Whether the dialed content is right or not is judged with the external instrument which is connected to the line cable.

23) Signal Send Mode 2
The signals concerned with V.34 & V.8 are checked. After this mode is activated, press the START key, and the signals will be sent in the following sequence. It can be used to check the modem. [ 1] No signal [ 2] 33600BPS [ 3] 31200BPS [ 4] 28800BPS [ 5] 26400BPS [ 6] 24000BPS [ 7] 21600BPS [ 8] 19200BPS [ 9] 16800BPS [10] 14400BPS [11] 12000BPS [12] 9600BPS [13] 7200BPS [14] 4800BPS [15] 2400BPS

1After shift to the FAX diagnosis mode, press RAPID 24. 2Press the START key. 3Turn on CML, and dial the following in the DB mode. 1, 2, 3, 4, 5, 6, 7, 8, 9, , 0, # 4Turn off CML 500 mS alone. 5Dial the following in the DP mode. 1, 5, 9, 0 6After dialing, turn off CML.
(Also switch the display with the [ ] and [#] keys.)

This mode uses the ordinary auto dial. (Accordingly, the signal sending time and minimum pause are all the same as ordinary. The measurement result in this mode is completely all the same as in the ordinary dial mode. Moreover, the same process as above is also done in the dial test mode which is executed in the product check mode.

20) Copy diag mode
In order to shorten the process time during production, this mode is used to automatically switch the copy mode. Three menus are provided. 1.

1 Set up two documents. (In case of two documents or more, there is no problem. 2 Press the START key. 3 Copy 1st document in the fine mode/density AUTO. (One sheet is printed in the ordinary copy mode.) 4 Copy 2nd (subsequential) document in the intermediate tone
mode/density DARK. (In the ordinary copying mode, one sheet is printed when the RESOLUTION key is pressed three times.)

24) JBIG Test Mode

1Enter the diagnostic mode. 2Press the RAPID22 button. ("22: JBIG TEST MODE" appears.) 3Press the START key to begin the JBIG test operation.

When copy test is tried during production or is checked in two modes (fine and intermediate tones), this mode is provided to reduce the troublesome work which makes the operator stand aside to change the mode. Accordingly, the fine and intermediate tones are merely switched, and the mode is not switched to another mode. (Input of the image quality/ density key is invalid.) 2. Try the copy in the mode fixed at COPY REDUCE 95% and fine mode/density AUTO. At this time, don�t change the soft key of COPY REDUCE. (Input of the image quality/density key is invalid.) 3. Continuously try the above items 1 and 2.

When both tests are completed normally, the buzzer sounds and "JBIG TEST NORMAL END" appears at the same time. If the decoding test terminates abnormally, the buzzer sounds and "ERROR: JBIG DECODE" appears at the same time. If the encoding test terminates abnormally, the buzzer sounds and "ERROR: JBIG ENCODE" appears at the same time.

21) Ring & Dial free
Used to reject dial tone check while autodialing is carried out. And used to change the bottom Ring frequency of auto-receiving to 13Hz.

22) Message check
Used to check the displayed message of communication for translate each language.
