Can't reprogram bottom message on TE-220

Don't know where NZTech was or the post but you need to press the CLK# button on the cash register(third key from left on cash register keyboard at top menu, Receipt on/off then CLK# ) and sign in the clerk.
if you have no clerks setup you may have to set up clerk

You have probably changed the key feature accidentally while programming items.

Try turning key to program and press the 0 button, then cash, then subtotal.
Turn key back to reg and try it.

You can download the manual from here, which will cover programming:

First you must turn on the bottom message printing

program 3

address 2122

set D6 to 3

Bottom Message word programming

LINE 1 address 0932
LINE 2 address 1032
LINE 3 address 1132
LINE 4 address 1232

Hi Good Day!
Before you reprogrammed it, check everything first,
if there is a reset setting, try to use it before you reprogramming it.

Reset the machine (initial clear) reprogram again. good luck

Try programming 8 zero's into the cash key in program 3 and program 1.

Brand? Model?

Hi. Try this:
Turn key to program mode 2 SUBTOTAL 1232 SUBTOTAL Now type the characters for the first bottom line of the receipt using the alphabet on the front of your department (item) buttons 00 (double zero button) CASH (maybe labelled CA/AT) 1332 SUBTOTAL Now type characters for second line 00 CASH 1432 SUBTOTAL Now type characters for third line 00 CASH 1532 SUBTOTAL Now type characters for fourth line 00 CASH SUBTOTAL
If you don't see the message change after 2 receipt prints in REG mode, then you have the commercial message and you'll need other codes. Just let me know. ---------------------------------------------------------------- Looking for a Casio TE-2000 manual? There is one here:
