Canon Pixma IP4300 bubblejet - explain Auto Power Off

    I've just received a Canon IP4300 which seems a great printer -
    certainly quick/accurate once it gets going, but I'd like to understand
    auto-power-off mode.

    Ok, so it seems to me it puts the printer into standby mode
    automatically after a period of time if printer not used. Fine, but
    what are the implications

    - Does it affect how often the heads are cleaned? Are they cleaned
    only when the machine powered on? Is this a "full" power on, or return
    from standby?
    - Or are the heads always cleaned after an idle period?
    - or on first print if time since last use > t seconds
    .... etc...
    - how much does it affect time-to-print-first-sheet?

    I did notice that having left the printer for 24 hours it took ages to
    print it's first sheet (it had powered down). Would this be much
    different if auto power off disabled?
    Would the power consumption differ that much?

    Thanks
    Nigel.

    I would not use any of those features. Just leave the thing powered on
    all of the time and forget it. I have never turned my IP4000 of in two
    years and have had zero problems. I always use Canon ink even though it
    is expensive.

    The auto-off feature activates when the printer hasn't received any
    print data for a user-specified period of time. There is also an
    auto-on feature, where the USB port is monitored for reception of
    print data which would trigger the auto-on circuitry. Both user
    settings are under the maintenance tab of the print driver (auto
    power button). It's also explained in the Driver Manual for the
    product.

    For comparison, power consumption of the iP4200 is 23w when printing,
    0.8w when in standby (power on), and 0.4w when powered off. Why it
    consumes power when off is not explained, so presumably it is
    monitoring USB activity whether auto-on is activated or not.
    Apparently, the only way to ensure absolutely no power is consumed,
    is to unplug the printer, or cut power via a power bar.

    The printer, if left powered on, will park the printhead on a
    protective pad after a period of inactivity to prevent the ink from
    drying out and causing clogs. Once this happens, there is absolutely
    no advantage to leaving it powered on, other than boot-up time.

    The power-off cycle also parks the printhead in the same fashion.
    Note, never cut power to the printer after initiating a power-off
    until you've confirmed it has completed the power-off cycle. If you
    cut power too early, e.g. pull the plug, or switch off a power bar,
    the printhead may not be fully parked, leaving the printhead
    exposed.

    Printhead cleaning cycles, besides being initiated by the user, can be
    initiated by 17 different conditions (note that this is from the
    iP4200 service manual, section 2.2). I imagine the iP4300 would be
    similar. Suffice it to say they'll happen automatically when they
    happen. If you'd like to research this further, get yourself a
    service manual for the iP4300.

    Hope this answers your questions...

    Thanks for the info. Sounds like the service manual may be an
    interesting read, but I'm still not really clear on the
    benefit/difference of auto power off other than the 0.4W vs 0.8W
    consideration (both pretty low).

    There are as many opinions as there are options when debating whether to power
    equipment off when not in use.
    I tend to trust the manufacturer, if they provide an auto power function then
    it is safe to use it. There will be some small power savings.
    I have an ip4000 and have used auto power off since new, close to 2 years with
    no issues of any kind.

    If the machine is in "Standby" (it has no real "off" mode, apart from
    disconnecting mains), it wont wake itself to clean. The "standby" APO
    sets it in is the same "off" as you can force it into with the power
    button on the unit.

    I think that is how it works, as it does have a clock.

    Under a minute for me. I print a sheet every couple days, right now.

    I don't know.

    >>Would the power consumption differ that much?


    No, as said, it has only one soft off mode.
