Casio pcr-2000a can not do a partial payment.

I spent quite a bit of time researching this yesterday, but nothing was popping up in results.

In effect, the customer buys the gift certificate with cash or credit/debit card and they get a 'promissory note' by way of a certificate. That is recorded as your sale on the day.

When they redeem it, they are buying goods but not paying. You need something that records the sale amount figure and a method of payment that is 'this has already been paid' so isn't in cash or debit card/credit card as the payment. with my POS Tills (bar and restaurant), I always got the rep from the company I purchased from to program them. They do it from a laptop which is a lot easier and faster. Call the company and ask. If they won't help, set up a PLU Key that is marked Gift Certificate, make the sale to that and manually deduct it from Charge. Circle it on your X and Z-Reading and write the deduction on the tail with the days trading amount at the bottom of the Z-Reading.

Cash total $6,250.00
Gift Cert $250.00
Adjusted Total $6,000.00

It isn't going to be every day, so only take a few minutes.

You don't do it at a dept level, you change it at the payment level.
Go into programming and choose key programming. Change the taxable status of the cash and other payment keys depending upon the desired status.

I would try to input an amount to see if it clears, if you still have manual that came with it there is a number that you can call for help

This machine is too cheap to have a void function so you will need to finish the sale with cash. Now you can reverse the transaction:
Turn the key to RF mode. Enter the items exactly as you did the first time. they will all be negative items now and they will go back out of the daily sales. Finish the sale with the same payment type (cash) and the machine will take the amount back out of the cash total. Now your sales report will have the correct figures.

If you want an easier method, buy a Casio with the CANCEL function and you can quit a sale at any time :)

If anyone needs a Casio PCR-T280 manual, one of the users has it here:

Maximum is 6 months

It is possible that there is a need to change payment acceptance method.

EJ stands for Electronic Journal. The ej is a record of all the sales made on the till since the last time the ej was cleared. If you dont clear it then it eventually fills up and stops the till from working until it is cleared. I dont have a manual for this model but there will be a report to print and clear the ej in your manual.

You use RECIEVED ON ACCT (sometimes labelled RA). That will allow you to receive money into the drawer without logging it under a PLU or Dept.
