3-2. EDS Mode Settings

The EDS (Electronic DIP Switch) mode in this printer has some functions that you can set as the power on default.

Turn the printer on while simultaneously holding the FONT, PITCH, and PAPER FEED buttons. You will hear an

acknowledging beep as power comes on. This indicates that you have entered the EDS mode.

In EDS mode, the buttons on the control panel are used as shown below in Fig. 1-4.

6. 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) command.

(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> @ : The printer exits from EE-PROM mode and is initialized.

<ESC> M @ : 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 n :

Function Address Capacity

<ESC> M W 0 <data> 00H - 7FH 128 bytes

<ESC> M W 1 n m nH 1 byte

<ESC> M W 2 <data> 2AH-54H 42 bytes

55H-7DH 42 bytes

• 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.

<ESC> M R : Print all data in EE-PROM in hex dump.

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.

Store data into whole area of

EE-PROM.

Store data (m) into the ad-

dress (n).

Store Auto-start software

data into EE-PROM.

6-4. Rewriting the EE-PROM

Follow this procedure to rewrite the EE-PROM.

(1) Turn the printer on.

(2) Load a BASIC disk in the computer.

(3) Turn the computer on.

(4) Set a sheet of paper in the printer, and press the ON LINE switch.

(5) Enter the program listed below and run the program.

20 LPRINT CHR$(27);”MW";CHR$(1);CHR$(&H01);CHR$(&HFB)

30 LPRINT CHR$(27);”MR”

BASIC Program Code What It Does

10 LPRINT CHR$(27);CHR$(26);CHR$(&H09) Enters the EE-PROM mode.

20 LPRINT CHR$(27);”MW";CHR$(1) Starts rewriting the EE-PROM.

CHR$(&H01); Address data from &H01 will show

EDS mode from the EE-PROM memory

map.

CHR$(&HFB) Data from &HFB will change the Line-

Spacing from 1/6" to 1/8".

30 LPRINT CHR$(27);”MR” Dumps all EE-PROM data to hexadeci-

mal.

(6) To complete the setting, turn the printer off.
