The State of On-demand Printing
The Ricoh Pro C900 was first shown at the 2008 On Demand show and later at Drupa. At 90 ppm, this color device claimed to yield 72,000 prints per toner bottle. Polymerized toner is pre-mixed with the developer and affixed in a single belt fusing unit to provide a wider color gamut and good fusing over a wider temperature range. It can print from 110-lb. cover to 165-lb. index.
The HP Indigo 7000 Digital Press prints 120 high-quality, four-color, A4-size ppm. HP says it is optimized to print large numbers of static jobs with run lengths ranging from one copy into the thousands, as well as variable-data work. The press offers low total cost of ownership (TCO) for customers exceeding the 1 million page level, significantly increasing the break-even point against offset.
At Drupa, Kodak launched the NexPress S3600 Digital Production Color Press, which prints at 120 ppm, the fastest in its S-Series. Modular features of the NexPress S-Class include input feeder options with up to 11,000 sheet capacity, collation capability of up to five different media, and both cut sheet and roll-fed paper on the same press.
The Xeikon division of Punch Graphix showcased the new Xeikon 8000, the Xeikon 6000 with the new 1,200-dpi imaging head and the new Xeikon 3300. With an astonishing printing speed of 230 A4 ppm, the new web-fed Xeikon 8000 has a monthly volume of more than 8 million pages.
The Xerox 490/980 Continuous Feed Printing System prints at 600 dpi and is a 20˝ wide printer that prints on substrates from 40-160 gsm, and runs at 223 fpm. It uses dry toner and flash-fusing technology, a process that does not use heat or pressure or make contact with the paper. This allows it to achieve speeds of 493 ppm (A4 or letter-size). Two engines can be linked to provide 986 ppm in duplex mode.
