Wow. You must be the last person on earth with one of these. The printer rubbers have usually disintegrated on them by now.
We'll see what we can do for you.
First thing to do is to try turning the key to each position and press clear, then CASH in each position.

Hi.
Try a flag clear:

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.

Now turn key back REG mode and try it.

The letter H appears in the screen. The register will not respond. Any idea to what the Letter H means?
