    Canon IPF700 bad ink line?

    Hi:

    We have a Canon Imagegraf IPF700 wide format plotter getting a dreaded "clean print head" error (error 2827 to be exact). After trying to clean the print head several times both using the plotter functions and manually with Magic Bullet cleaner and wasting tons of ink, still the same problem. The nozzle check pattern shows up perfect but no magenta (at all). After lots of reading I decided to get a new print head even though the one in it was only 6 months old.

    After wasting more and more ink, a maintenance cartridge and putting in a brand new print head...ugghh...same error and same nozzle check pattern (everything good but no magenta). I can look at the magenta ink line but really, I can't tell (doesn't look magenta but it looks like it has something in it but it may be just old residue). Either way, I'm fairly sure it's just not getting magenta ink. In fact, when it's replenished ink and wasted almost every ink cartridge, the orignal magenta is still almost full.

    Questions:

    - Is there a way for me to fix myself? I can't seem to find any info online. Every thread on the subject seems to end up with the same "replace the print head" advice.

    - Is there a way to bypass this? Why of why can't I just plot anyway? I could care less about colour, we plot 100% in black and white. I've tried everything I can in both service mode and otherwise, even disabling the nozzle check which doesn't seem to do anything. Clearly the plotter has the ability to plot since I can do any of the test prints from service mode but it won't from normal mode so the plotter is not usable even though it can function.

    I'm really set on not letting this thing beat me. I've sunk too much money into it trying to chase this down and even though the plotter is older now, it really hasn't seen a lot of use. It would be a shame to waste it.

    Thanks.

    Sad to say, everything you'll try will be expensive.

    The two head killers are generic ink cartridges, and low usage. Worse: both at the same time. You will have to change the printhead again, regardless.

    1) Replace any generic ink cartridges with OEM.
    2) Replace printhead.
    3) If you're not using the plotter enough, increase usage. It should never sit for a continuous week unused. Ink based systems love to be used, hate to sit idle with printheads and tubes hardening up.

    =^..^=
    If you'd like a serious answer to your request:
    1) demonstrate that you've read the manual
    2) demonstrate that you made some attempt to fix it.
    3) if you're going to ask about jams include the jam code.
    4) if you're going to ask about an error code include the error code.
    5) You are the person onsite. Only you can make observations.

      Hi, thanks. As mentioned, I already changed the print head with a brand new one. I've never used generic ink. I agree 100% that low usage is the culprit, I can fix that of course as soon as I get this thing back running.

      My questions still remain though:

      - The magenta ink is definitely not flowing and it has nothing to do with the print head. Can it be primed or unclogged somehow?

      - Is there a service mode (or other) method I'm missing to force the plotter to ignore this sensor problem? I just want to plot in black and white.

      Thanks, still looking for solutions here.
