EE-PROM mode

6-1. Outline

These settings can be changed in the EE-PROM mode by writing data directly to the EE-PROM on the main logic board:
Setting EE-PROM mode
• Send <ESC><SUB>(09)H command.
Canceling EE-PROM mode
• Initialize the printer by sending <ESC>@

6-2. Explanation of special control codes

<ESC>@ Exits printer from EE-PROM mode and initializes the printer.
<ESC>M@ Returns all data in the EE-PROM to the factory settings. After the buffer is cleared, the buzzer sounds. If
the printer is powered off before the buzzer sounds, all data in the buffer is not cleared.
If all data is not cleared from the buffer, operation is not guaranteed. Be sure to allow the buzzer
to sound before you turn the printer off!
<ESC>MWn
<ESC>MW0 <data>
<ESC>MW1nm
<ESC>MW2<data>
• The data (m) used in the commands above are stored in the specified address in order (n).
• When the data to be stored exceeds the specified capacity, subsequent data are ignored.
• Data are stored in the EE-PROM according to the memory map. (See section 3. EDS mode setting and
6-3. EE-PROM Map.)
• After all data are stored, a beep indicates the completion of storage.
• If the printer is powered off during data storage, data stored before power off are valid, but subsequent
operation of the printer is not guaranteed.
Do not power off the printer while data is being stored!
<ESC>MR Dumps all data in the EE-PROM to a hard copy.
For an example of using these control codes, see section 6-4. For the corresponding EE-PROM addresses, see the
EE-PROM memory map in section 3-2. EDS mode setting and 6-3 EE-PROM Map.
