If you have a printer problem, call Lexmark's technical support request via the Web. If your problem cannot be resolved by phone, Lexmark will dispatch a Lexmark trained technician to your location - usually the next business day. By purchasing a LexOnSite repair extended warranty, a customer is eligible for on-site Service during the term of the extension. If your original warranty was a carry in product, then, you will be required to purchase a LexOnSite repair Upgrade to cover your original warranty and any extended warranties purchased.
