On-site exchange warranties mean that rather than sending an engineer the manufacturer will send the customer a new / refurbished machine or ship the part needed if simple to fit. The faulty machine will be collected at no cost to the customer.

Off-site repair warranties mean that rather than sending an engineer the manufacturer will collect the machine at their own expense, fix it and ship it back.

RTB (Return-to-Base) warranties give customers free phone support but may require them to ship the machine back to the manufacturer for repair at their own expense if necessary.
