I have a casio ce-4200 and i am having a problem. I was getting an error E03, and I read a post on the forum to reset. I turned key to off, held down receipt feed, turned key to program, the FFFFFFF came up, then I hit subtotal. It printed the confirmation fine. all is good. but....now the register is stuck at 0 and will not accept commands. I have tried a power cycle, unplugging the unit, as well as repeating this reset process. any help would be very much appreciated.

Seems the battery in your till needs replacing and that is why there is only one zero as it has lost all its programming.

reset till with 21000 .. hold down journal feed turn off and on when row of 000000 type 21000 then sub total..

try that

hey, the batter could potentially be the problem, i have had this thing for a while. I tryed the 21000 reset, and it just ended up giving me an error E03, the error i started with :X tryed the normal reset again but still nothing. any other tips or should i probably just replace the battery?

You will need to replace the battery anyway. You should still be able to setup the till, but if you turn it off you will lose all information again.

Try this:

Turn till Off
Turn key to PGM
Hold down Journal Feed while switching on
Enter 11501 and press Subtotal
