EE-PROM Mode

6-1. Outline

The settings described below can be changed if data is written to the EE-PROM on the main logic board.
The mode for writing to the EE-PROM is designed for use by maintenance workers, not for use by the general user.
In addition, this mode is subject to change without prior notice.
EDS (Electric DIP Switch) settings
Misalignment correction
Top margin in auto-loading
Allowable distance of paper out detector
(1) Setting method
There are the following two methods to set the EE-PROM mode
a. Power the printer ON while ON LINE and PAPER FEED switches are held pressed.
b. If the printer has already been powered ON, send <ESC><SUB> (09)
(2) Canceling method
There are the following two methods to cancel this mode.
a. Power the printer OFF.
b. Initialize the printer by sending <ESC> "@" command.

6-2. Explanation of Special Control Codes

The control codes shown below are provided for use in writing to the EE-PROM.
<ESC> @
<ESC> M @
<ESC> M W n
<ESC> M R
An example of the use of this control code is described in section 6-4. The corresponding EE-PROM addresses may be
found in the EE-PROM memory map in section 6-3.
: The printer exits from EE-PROM mode and is initialized.
: All data in the EE-PROM are changed to factory settings.
After the buffer is cleared, the buzzer sounds.
If the printer is powered off the before buzzer sounds, all data in the buffer is not cleared.
Since the data values are regarded as illegal ones, the operation in this case is not guaranteed.
:
<ESC> M W 0 <data>
<ESC> M W 1 n m
<ESC> M W 2 <data>
The data (m) following the above commands are stored in the specified address in order (n).
When the data to be stored exceeds specified capacity, the subsequent data are ignored.
Data are stored in EE-PROM according to memory map.
After all data are stored, a beep indicates the finish of storage.
If the printer is powered off during data storage, the data which have already been stored are
valid but the subsequent operation is not guaranteed.
: Print all data in EE-PROM in hex dump.
Function
Store data into whole area of
EE-PROM.
Store data (m) into the ad-
dress (n).
Store Auto-start software
data into EE-PROM.
