HP's new enterprise multifunction printers are not for sale
The devices use multiple Edgeline printheads with in excess of 50,000 nozzles between them. Even if individual nozzles fail, a head can continue to deliver full quality thanks to built-in redundancy. As many as 20 percent of the nozzles can fail across the entire head without affecting the quality, although speed may suffer slightly.
Despite producing millions of test pages, "we've never seen any kind of failure like that," said Cutler.
Furthermore, a built-in densitometer monitors the output for consistent quality - the CM8000s "will self-heal," said Paul Lim, business category manager for Edgeline, Hewlett-Packard Asia/Pacific and Japan.
The durability of the output - pages emerge dry, resist smudging, and are highlighter-proof - is achieved in part through the use of a bonding agent deposited on the paper ahead of the ink drops. This agent catalyses the bond between the cellulose in the paper and the ink pigments. The resulting hydrophilic bond is the source of the smudge-resistance.
Another benefit is increased resistance to curling and wrinkling due to humidity. "One of the fundamental issues [with inkjet technology] was putting too much water into paper," said Cutler, adding that the bonding agent helps avoid doing that.
