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 PB mode and DP mode.
When this mode is activated, the following operations will be automat-
ically executed . Whether the dialed content is right or not is judged with
the external instrument which is connected to the line cable.
After shift to the FAX diagnosis mode, press RAPID 24.
(Also switch the display with the [ ] and [#] keys.)
Press the START key.
Turn on CML, and dial the following in the PB mode.
1, 2, 3, 4, 5, 6, 7, 8, 9, , 0, #
Turn off CML 500 mS alone.
Dial the following in the DP mode.
1, 5, 9, 0
After dialing, turn off CML.
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. Set up two documents. (In case of two documents or more,
there is no problem.
Press the START key.
Copy 1st document in the fine mode/density AUTO. (One sheet
is printed in the ordinary copy mode.)
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.)
When copy test is tried during production or is checked in two modes
(fine and intermediate tones), this mode is provided to reduce the trou-
blesome 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.
1. [Full black pattern]
2. [Intermediate tone 2 pattern]
3. [Intermediate tone 1 pattern]
4. [Mesh point pattern]
