    Memjet print head revolution delayed

    It will now be next year before the first printer using innovative technology developed by Silverbrook Research goes on sale.

    Silverbrook promised in March 2007 that new printers based on its
    revolutionary Memjet technology would hit the market this year, but a
    move away from a small-format photo printer to letter-size has pushed
    back the launch date.

    That Memjet technology now
    promises a 60-page a minute letter-sized colour printer for less than
    $400.Bill McGlynn, chief executive of Silverbrook’s US-based
    Memjet Home and Office, says there are a couple of reasons for the
    switch away from a photo printer.One is that volume sales of small
    photo printers are dropping,
    “meaning that customers were voting that they would rather go some
    place and have their photos printed rather than trying to print them at

    Secondly, getting almost perfect quality printing in a very small
    format proved a tough challenge with a nascent technology, so the
    company decided to go first of all for a letter-size printer.”You don’t have to have absolutely perfect quality on the first
    version of the technology if you are aiming at the home and office,”
    McGlynn says.A photo printer is still on the cards, as is a wide-format machine for printing posters, and one for labels.

    Silverbrook also has a mobile phone format prototype.
    to McGlynn, Silverbrook has been working 13 years on the
    Memjet technology, the secret of which is a print head that spans the
    width of the page and prints the entire page in a single pass.The print
    head consists of a continuous row of 1mm by 20mm silicon print chips
    connected end-to-end.

    Each chip contains 6400 nozzles,
    equalling 32,000 nozzles in total
    for a 100mm print head and 70,400 nozzles for a letter-size print
    head.Silverbrook says nozzle density is 17 times higher than the nozzle
    density offered by the market leaders in their print heads.Silverbrook
    is not interested in manufacturing final products itself and is looking
    or partners to bring the printers to market.

    Perhaps not surprisingly, traditional
    printer companies have not
    been banging on Silverbrook’s door to incorporate the Memjet technology
    in their lines.It would disrupt their pricing models, says McGlynn, as
    the likes of
    Hewlett-Packard and Canon would charge about $1000 for a 60ppm
    printer.Consequently, the company is partnering with consumer
    electronics companies keen to enter the printer market.

    McGlynn will not name the partners but says they are brand-name
    consumer electronics companies anxious to get their hands on the final
    version of the Memjet technology so they can have product to ship early
    next year.Meantime in Sydney, Silverbrook, which says it employs more than 400
    scientists, engineers and support staff, has a growing list of
    vacancies on its website as it works on development of print head
    prototypes that will eventually be manufactured in Taiwan and China.

    The company is looking for 45 engineers, scientists and even lawyers – up from 30 in May.
    printer industry consultant Jim Lyons says traditional printer
    companies are snubbing the technology.Lyons, who like McGlynn, is an HP
    veteran, says: “It took
    Silverbrook 10 years to get to the point where they were last year. It
    is reasonable to take two years from then to get a really wrung-out
    product that people can sell.”
