Question moved from Televisions.

It appears to be a Memory Issue on all Casio tills. It is also in the manual.

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.

Did you get it going?
Sounds like a faulty battery. It should be changed by a technician every five years or so

The machine is in the middle of a full program clear. It may have a flat or faulty battery. It has probably lost all programming. Try a flag clear first (from your programming manual). Otherwise, have the battery replaced and re-program it.

Ok. See if you can get rid of the buffer full error for a start. try pressing clear (C) then press Subtotal. You should see an amount on the display. Now press the ERR CORR/ CANCEL button. This should stop the sale that you are stuck in.
Turn the key to Program mode. If it gives error as you turn the key, then you haven't finshed in REG, turn back to REG and try to end the sale first.
If you see P01 on the display, it has worked and then do this:
1 SUBTOTAL 0 CASH SUBTOTAL 3 SUBTOTAL 0 CASH SUBTOTAL.
Now turn back to REG and try it.
If it still didn't work, let me know what happened, and I'll show you another method

PGMX means the machine is trying to print a current program report. It may have been interrupted. Try this procedure to jump it back out:
Turn key to PROGRAM mode. Turn power off at wall. Hold RECEIPT FEED down - keep your finger on it. Turn power on at wall. Wait 5 seconds, then let go of RECEIPT FEED. You should see "FFFFFFFFFF" on display. Press SUBTOTAL. Turn key back to REG mode (you may need to sign on if asked)

The only time it will blow the fuse is if someone has shorted out the cash drawer wiring. Check the wiring to the drawer first, and insulate any bare wires. Then you can replace the fuse. It is a solder in type on the main pcboard. Sometimes the half watt resistor in series will be cooked as well. --------------------------------------------------------------------------------------------------
