How can i reset my casio te 2000to factory settings as it wont let me sign in, i have the program cd but can do nothing, i bought this from a bankruptcy auction so maybe it is broken? pete

Hi. You don't want to reset it unless you have to, as this will mean a lot of extra work for you. Better to find out why it won't let you program it.

First of all, do this:

Turn the power off at the wall
Turn the key to PROGRAM
Now keep your finger on the RECEIPT FEED button while you turn the power back on, and keep holding it down for 5 seconds.
Let go, and you should see "FFFFFFFFF" on the display
Press SUBTOTAL
Wait for print out.

On the print out, near the bottom, you should see "FC" on the left, and then a number on the right.
Tell me what that number is, and I can help you further.

Power off at wall
Ensure receipt and journal rolls are installed
Switch PGM mode
Press and hold receipt feed and journal feed
Power on at wall
Keep holding feed buttons for ~5s
?
Profit.
