Wear and tear on networked printers in businesses and other organizations cause printers to break down with dismaying frequency. For most printers, the manufacturer's warranty covers parts and labor for a one year period after the product was purchased, and allows for replacement of defective products at no charge. In many cases, warranty extensions can be purchased at the time of the original sale, providing service, support and routine maintenance from the OEM over the printer's entire life span. However, local repair services specializing in printers, copiers and other office equipment repair often offer faster, dedicated service at much lower prices.
