Great old machines. The 240CR is only simple, so you just turn the key to Z mode and press CASH to re-set the report. The grand total (GT) may not reset because it is usually a security feature, but you don't need it. Just ignore any GT on the report. all other totals should be cleared and if you do it each day, you'll get the figures you need.
If anyone needs more information, the 240CR manuals are here:

I can send you a new transfer kit for 150 € + shipping cost.
