Brother MFC dead after power cycle?

    Hello Folks,

    Since this machine is widely used maybe one of you had this happen:
    Moved it to the shiny new office, turned it on, nada, zilch. Only a
    backlit blank LCD. Power cycling, pressing and holding buttons and such
    produces no reaction.

    Any ideas how to fix/reset the thang? Or does this mean it's dead? It is
    a Brother MFC-7820N but I think they are all similar.

    Jim will say I should have bought a HP. But, my HP needs 3-4 power
    cycles per week while the Brother only needed one a month. For today's
    design standards in consumer gear that's probably "good".

    Not that any of this is likely to help you....I had the same thing after a
    mains power bump last week. Couldn't get the thing to respond at all so a
    replacement was purchased. After sitting for a couple of days I repowered
    the failed unit and it decides it wants to work again and now performs fine.
    Dried out caps in the SMPS?? beats me.

    You can try smacking it ala Arthur Fonzarelli to see if there's a loose
    connection, but the fact is that this end of the spectrum, regardless of
    brand, is junk from the day it's made.

    I actually beat the living heck out of some Brother "consumer" lasers,
    but don't respect them anyway - they keep turning "error print" on
    despite my turning it it off (setting is not saved - hundreds of pages
    of crap when their bootleg "not quite postscript" fumbles something
    coming in) and I bought and junked 2 more to get "drum units" that cost
    more than the printers they came in.

    Then again, I have a pair of HP4200 moderately "good" office lasers that
    don't work terribly well considering they cost a lot more, and some HP
    4000's (older, less sexy "office" laserprinters) that work better than
    both the newer HPs and the Brother's, and cost less to operate to boot.

    I prefer scanner separate from printer in terms of overall function and
    general quality sometimes being slightly better. And at least you only
    have to toss the part that actually breaks, if they are separate units.
    Any good scanner package will still let you "make copies" from the
    scanner to the printer if you want to.

    So maybe I'll wait a few days to see if the problem fixes itself :)

    It's been good to me so far. It always had a propensity to hang itself
    up but not nearly as often as the HP (I wore out one power cord from all
    the unplugging).
  6. Joerg

    Joerg Guest

    Yeah, but it's also about space. Not a lot there, plus I don't want to
    cram several more USB/network cables into the already packed channel.

    Anyhow, Costco Online has the next model for around $200 after rebate.
    If it takes the same toner cartrdige I may bite. If it only lives two
    years like this one that's still under $10/month :)

    Just installed a brand cartridge and then the dang thing croaked :-(
  7. I have had almost comically bad service from HP lately.

    Have you looked for a Reset button, Joerg? ISTR my circa 1993 IBM Thinkpad has one buried inside,
    on the mainboard and in a place that's accessable only to someone who *really* wants to get at it.
    As you know, electronics that isn't really off when it's powered down can get confused. For this
    reason I try to avoid owning stuff that has a momentary power switch... like the current &^@%$!!
  10. Joerg

    Joerg Guest

    Well, Brother was not forthcoming with any info, they just repeated some
    stuff from the FAQ which, of course, I had already read. Can't find a
    reset button. The power switch seems to be a real one, although one
    never knows.

    Have you checked to see if it is supported under Linux
    for when you permanently decide to forsake The Borg?

    The current one (that died) is in there, the new one (7840) ain't:

    But it won't matter much since my biz software binds me to Windows.
    Having used NT for roughly 10 years after it's "end" I don't see any
    problems with XP for the next decade or so. And that NT machine was only
    retired because the wheels started coming off.

    I tried Ubuntu last year. Not my cup of tea, I especially do not like
    the file system under Linux, then all this sudo and root stuff, too
    cumbersome for my taste. Other than that it worked quite nicely, in fact
    it's still here on this PC.

    That's what I am using to run Ubuntu, Sun VirtualBox. Basically to be
    able to run gEDA but that has turned out not to be an good fit for me,
    gschem lacks quite some features of mainstream schematic programs. But
    who knows, it might get there.

    Should be possible. But there are some things I plain don't understand
    why they were done that way, for example not allowing users to write to
    CAD library directories. It is absolutely essential to be able to do that.

    ....or until your hardware / Windoze install barfs
    and you find that M$ has shut down its XP Product Activation servers.

    ....or Windows Genuine Advantage barfs
    and puts you in the 22% that it wrongly calls pirates
    and cripples your M$ OS by remote control. Read the EULA lately?
    8-( ...then there are the folks who have to move back & forth
    between e.g. RedHat-based systems & Debian-based systems.
    At least you didn't have that going on.
    Horses for courses.
    WRT my reference to Linux support, I was actually thinking about
    worst-case where you can boot to a Linux CD and still print a file.
    Having an app that opens under Linux would seem to be the snag.
    Using open source cross-platform apps could be a boon there.

    Thought that began with version 11? Which, coincidentally, is when I
    stopped upgrading; negative marginal value. Still happily using 2001i.
  16. Got an ESR meter? If there was no smoke and it's dead, I bet you will
    find at least one 'lytic with very poor ESR. What you're describing is
    a classic, see it on older Tek scopes all the time.

    You are proposing that people who KNOW they are running warez
    are going to submit themselves to the test.
    Now, *that* is where the bulk of the problems do seem to arise.
    It _should_ be a PR black eye for M$ to call folks thieves
    yet people continue to give money to those who abuse them.
    You and 99.999% of those who are aware.
    No phone-home software, no product activation, no dongles,
    no DRM, no writing to my boot sector. Thank you.

    ....and for those who feel they aren't getting their fair share of
    there's Linux Genuine Advantage(tm). :cool:

    Isn't that called "value added marketing"? Whenever a price isn't
    clearly stated but you are urged to call a "value added reseller" that
    raises my hackles. Usually meaning that I won't buy. With hardware I've
    even seen vendor mark-up, IOW they charge a price well _above_ the one
    listed on the mfg's web site. Of course that also resulted in a decline
    on my part.

    There are a couple of GPL mathematics programs. However, unfortunately
    universities get suckered into MatLab and such, probably they are
    offered really sweet deals. I guess that's one way to achieve vendor-lock.

    Was it frozen in transit?

    Defrosting and drying out is probably a reasonable precaution for
    moves made in winter weather.

    Nope, just from one office to another down the hallway. Carried with
    great care, no bumping etc. Plugged it in ... dead.

    It's cold right now and the wood stove is on 100% duty cycle. 45F during
    the day, 35F or so at night. And very windy which turns all the windows
    into gigantic heat sinks :-(

    Besides the dead printer the move also meant lost WLAN coverage in the
    living area. So besides some cable shelves now I'll have to do some
    'tenna building. In the garage, of course, where it's a scorching 40F
    right now. Oh well, as long as I don't cut myself with the sheet metal.
