    From what I can tell, it's just not possible to go by the brand, some brands
    are almost always junk, the rest are a crapshoot. I've come to the
    conclusion that consumer grade inkjet printers are trash, occasionally you
    get lucky and one will work long enough to run a cartridge or two out of ink
    but there's duds from all brands.

    Amen!!! I've given up on inkjets. The little HP Laserjet 1020 I
    just bought is perfect for the small amount of B/W printing I do.

    I have a C60 that I use once a week. I use only Epson cartridges and
    I had an original epson stylus color, with the front loading paper tray, one
    of the best printers I ever had lasted about 6 years, never clogged, never
    jammed, ink lasted fairly long time. I saw friends with color II's garbage,
    and the rest of the range since then I consider garbage. One thing about
    inkjet printers is you really should print something with back and color
    about once a week, even if its just a test picture or some black and color
    squares in paint. I curently own a HP 960 runs ok was fairly cheap even if
    the ink costs a lot. But I dont use it that much, I have a brother HL 1650
    laser printer for the bulk of my printing.

    color laser printers are not as expensive as they used to be, and in
    the US, it seems neither is gas heat.

    roll with the times I guess

    YEAH, Lexmark. WE have several in use in the front offices as well and
    have had NO problems with them what-so-ever.
    The brand of ink has little to do with how reliably a printer
    performs. If the basic design is flawed it'll clog with whatever ink
    you use.
    To answer your question though we had just as many clogs and seal loss
    problems with Epson's cartridges as with the better pro inks and tanks
    we used. (German made tanks and pantone inks.)
    Problem is Epson printers use pizeo prints heads and the whole concept
    sucks, it just isn't as reliable as the other designs available.
    Besides if you subscribe to the notion that it's ok to buy a printer
    that MUST only have the oem's ink cartridges you certainly can't be in
    this as a professional, or maybe you work for Epson?(Epson is
    basically a company of liars, what with their telling all their
    customers that the use of other brands of ink cartridges voids any and
    all warranties when as a fact of law it's just no so.)
    On the 800's we had we experienced constant clogs plus the software
    drivers were pretty lame as well.(The start up and logic functions on
    these models were tedious and slow. enough to drive even the most
    patient to fits, especially when after finally getting them in a green
    lite mode all you'd get is banding or total clogs on one color or the
    other.)
    Don't worry if you're any indication of the Intelligence Quotient of
    your customer we wouldn't want them walking in our shop in the first
    place.

    Right! I spent hours of down time dismantling our 1500 and 3000 and
    cleaning the heads using an ultrasonic cleaner, only to have them clog
    up again after just a few hours.
    A total waste of time, especially if you're the basic consumer who
    just wants a printer that'll work when you hit the print key.( To some
    extent it's justifiable to do PIA maintenence if the printer in
    question gives better results when working properly and decent runs
    can be had between down cycles.)

    You were lucky with that IIs. In the early production models of that
    printer they were reported to have very stringent QA on the line and
    put in better built print heads to start with. Not so on the later
    models, they'd gotten their rep established and were only interested
    in the bottom line after that.
    In the mid 90's and a bit later for overall image quality inkjet was
    the only thing cost effective for achieving tonal quality approaching
    four color offset for small runs and such though.(I leased a big Xerox
    four color laser setup back in 96 on their promises that it'd match
    4-color in tonal gradation and overall gamut. Just more sales rep BS
    though. Far to contrasty and only poor gamuts to boot.)
    Happily today's laser printers are a far cry from then. I'd be using
    more myself if the cost per page would only get lower for color.
    I've been pretty happy with the results from the plotters we've been
    using, especially inregards to cost per page.
    I'm currently testing a six color thermal ink plotter one of my reps
    loaned me and am much impressed with it's output.
    Now if he's only telling me the truth about the low cost of the
    cartridges it might be worth the price tag.

    The marketing strategy with most of the inkjets printer companies is
    aimed at making most of their profits from selling you the cartridges,
    hence the reason the printers are often so reasonably priced. Just a
    means of getting the buyer hooked on the never ending need to purchase
    yet another cartridge.(no better than the average street dealer in
    that repsect.)
    If they use a foam core it can actually promote clogging and air
    bubbles etc... Also lets them put less ink in the cartridge in the
    first place.( And NO, that old argument they put forth about the
    sponge regulating the flow of ink is just so much BS. Proper sized
    aperture ports would do the same thing while leaving MORE room in the
    tank for ink. That'd be too fair to the consumer though, not to
    mention cutting down on cartridge sales.)
    With all the inkjets we use in the shop and the front office I use
    aftermarket ink and tanks, it's the only way to see any profit out of
    any inkjet.
    If you want to try and keep your Epson going I can give you all sorts
    of inside info and tricks on how to get it to produce at least part of
    the time, just post your questions/problems.

    I had slightly better results out of the blanks I got from Nujet and
    the seals I got from a German company, though in the end it amounted
    to just to much down time babying these crappy printers.(And the mods
    I had were supposed to be their best pro units.)
    Sadly true about the state of market for consumer units.

    Say no more. You're an airhead.
     
  11. No, and that is, or at least was, especially true of Epsons. The right
    ink is/was critical with them.

    If the aftermarket ink is the same type of ink as the oem it will do
    the same job.
    Ink for the pizeo printhead printer IS a different type as that for
    all the other types of inkjet printers on the market but is easily
    duplicated. I used aftermarket ink refills from Nujet for some of my
    Epson's that actually flowed BETTER than the oem stuff and gave fewer
    clogs once you got the heads cleared and primed.
    Problem is Epson made their printers so shoddily that on most it was
    virtually impossible to get a tight uniform seal from ANY
    cartridge.(seal between the cartridge and the printhead assembly is
    achieved with a nitrile rubber o-ring in the cartridge ink port.)
    I service all the equipment in our print shop from the AB-Dick and
    Heidleburg offsets right down to the lowly inkjet machines and I
    stripped down a couple of those older Epson's years back to try and
    fix the problems.
    The printheads are built of some pretty cheap material and careful
    measuring with micrometers showed some pretty gross irregularities in
    the seal contact points.( likely piss poor injection molding during
    manufacturing.)
    On our 1500 it was nothing short of a miracle that we ever got it to
    work out of the box.( started clogging and losing seal after the first
    month.)
    I tried replacing all the nitrile o-rings in the ink cartridges with
    slightly fatter seals and it solved the seal loss problem to an extent
    but we still had problems with clogging,especially if the machine had
    sat for more than a week. Having to run dozens of cleanup sheets to
    get it to print one single proof is insane. Perhaps that's why the
    collection of Epson printers we have are collecting dust in a storage
    closet.

    In the office we use the Z42's and they all work jusr fine. I did buy
    them as a batch and direct from Lexmark.
    I've also had much better success recharging the cartridges for these
    machines vs. some of the other makes out there.
     
  14. I'll have to take your word for it, experience being a better teacher
    than training...I was told it was a cold versus hot ink thing...true?

    The pizeo principle is a "cold ink" process.( Epson actually holds the
    copyrights/patents for the process)
    Other inkjet printers use heater coils to preheat the ink in the ink
    tanks. Pizeo once upon a time held the title for for the highest dpi
    attainable with inkjet printers, not so anymore. R&D on standard
    inkjets finally caught up with Epson around '99.
    The thermal printers use a dry ink on a ribbon and a hot pinhead
    assembly and in my opinion are the easiest and simplest low cost
    solution to achieve photo quality color images.( I've used some of the
    most expensive dyesub and laser units in the commercial market and a
    low cost 400dpi thermal ribbon printer gets really close for much less
    money.)
    400dpi with dry ink has virtually no "spread" whilst those wet ink
    printers with dpi's in the 1,800's or higher suffer from marked ink
    spread/patterning.( unless you use a top grade photo paper, something
    not possible if you're trying to output publications etc...)
    AS a result that low dpi thermal ribbon printer produces a color print
    that has much greater apparent sharpness.
    That said great strides have been made in dithering algorithms in
    inkjet printers and if you use a good grade of paper decent results
    can be achieved with many of the inkjet printers on the market.
    It just tends to be more problematic balancing the grade of ink used
    and types of paper one has to use.( On alot of print jobs we do we're
    forced to use some pretty bad "rag stock" and using an inkjet to drop
    in color images here and there can be really trying. We have to use
    third party software drivers that allow us to control the volume of
    ink flow when printing on paper that's really open fibre.)
    On my Encad plotter we have potentiometers that allow us to adjust ink
    flow easily.

    Right! I spent hours of down time dismantling our 1500 and 3000 and
    I used Canon inkjets for years, but in order to use pigmented fabric
    inks I had to get an Epson. Started by finding an old Epson 1520 in a
    thrift store, no cartridges, no idea how long it had sat unused. Took
    me a couple of weeks to get it printing 100%, but after that it was
    flawless. I get obsessed... so I started to pick up various Epson
    printers, so I could teach myself how to get them going.

    Now I can get just about any Epson unplugged, of course as long as the
    heads are not burnt out. I don't disassemble them for this, unless
    there's been something like a big ink leak. Never used any ultrasonic
    cleaners. Syringes are bad news because it's way too easy to put
    upwards of 70psi with little pressure if using a small syringe.

    I wrote up some of what I learned, for what it's worth.

    -All- inkjet printers say not to turn off except by the printer's power
    switch. All of them.

    Yes, the Standby Park position is the same as the Off Park position,
    however the printer does not instantly go into the Standby Park
    position and may move out of position for a short time for no apparent
    reason.

    Careful about shaking cartridges. With older Epsons, they use a sponge
    foam filler and you can end up filling the foam with air. With newer
    non-sponge cartridges, you can end up with foamy ink and cause a bubble
    to get pulled into the head, mimicking a clog and requiring the waste
    of loads of ink in cleaning cycles.

    I've read notes from people who say they've had Epson cartridges
    emptied by about 15 to 20 cleaning cycles.

    Also, by the spike design of the print head/cartridge seal, it
    virtually guarantees an air bubble will get trapped. You can either
    waste ink on cleaning cycles to clear it, or let it sit a day for the
    bubble to rise out of the way. This is my experience.
