Electronic Cash Registers from time to time will require parts to be replaced. We recommend that in most cases you should have your Sharp Electronic Cash Register or SAM4s Cash Register repaired by a Cash Register Dealer. However if you are a do-it-yourselfer we do make a wide variety of SAM4s cash register parts available as well as Sharp. Please beware that we can not warranty a part that you decide to install yourself. Also don't forget we do offer repairs and parts for the SAM4s cash registers
