Liquid spilled on it? Case opened up? Try unpluging it then wait a while and replug it in again and try it.

With paper loaded properly, turn off/unplug register, turn MA or Service key to "Blind" position (approx. 5 o'clock), turn on/plug in register. "Status-C" will print on the receipt. Some of these TEC's won't reset after changing paper, and this procedure becomes necessary after each installation of a new roll of paper.

You should do a status clear on the cash register.

There should be a section in the manual called something like receipt message programming. I don't have any information on this model, but I found a manual here: http://the-checkout-tech.com/manuals/cashregisters/TEC_FS-1650_programming_manual.html

Hello, Here is a link to the instruction manual (I believe). I hope it helps.
