The result will be notified with the number of short sounds of the buzzer
as well as by printing the ROM & RAM check list.
Number of short sounds of buzzer 0
3. 3. Aging mode
If any document is present, copying will be executed sheet by sheet. If
no document is present, the check pattern will be printed sheet by sheet.
This operation will be executed at a rate of one sheet per 5 minutes, and
will be ended at a total of 10 sheets.

[11] 2400BPS (V27ter)
[12] 300BPS (FLAG)
[13] 2100Hz (CED)
[14] 1100Hz (CNG)
3. 7. Memory clear
This mode is used to clear the backup memory and reset to the default
settings.
3. 8. Shading mode
The mode is used for the shading compensation. For reading, set up the

The compensation memorizes the reference data of white and black for
reading.
Moreover, the memorized data is not erased even if memory clear mode
is executed.
3. 9. All black print

Before sending in this mode, it is necessary to set the other machine at
the entry data receive mode.
The following, information will be sent to the remote machine:
1. Telephone list data
2. Sender register data
3. Optional setting content
