In a demanding and fast-moving work environment, a high ribbon yield is essential, and with 10 million characters per ribbon, this marks out the LQ-690 as a leading force in the flatbed market. It is also cost-effective with long ribbon replacement cycles, low running costs and total cost of ownership. Durable and built to last, users will be assured by the MTBF (mean time between failures) of 20,000 power on hours, plus a print head life of 400 million strokes/wire. This results in greater productivity and less maintenance - essential when producing large amounts of documents and data.
