How can i fix JCM Gold 2150 if we are getting continuous beep-error sound?

You might try resetting the register:

1) Turn off the power switch located near the right side back corner.
2) Turn the mode lock to REG.
3) Simultaneously press the numeric 1, 3, 7 & 9 keys.
4) While holding down these keys, turn on the power switch. WHen the register stops printing release the keys.

You may need to login a clerk after performing this procedure. Good luck ...
