    this is craziness, red stopped printing, took things apart, and the damper is really loose, then noticed the rubber nipple from the print head is IN the damper.....

    What do i do? have old print heads, swap the rubbers?

    How do i keep everything from drying out in mean time?

    That black nipple is ABS plastic, not rubber. You'll need a new manifold (or if you take one off an old head you need to clean it as good as possible and make sure ink flows freely through it). You have to remove the head, unscrew the manifold, reattach the new one and keep the grounding strap in place. Then install the head and redo the alignments.

    Never work with the machine plugged in and wait 15 minutes after it's unplugged before you do anything.

    ok so bypassed that fuse with a 2 amp, now thats blown so no yellow or megenta yet

    whats the deal with that ground from the print head, couldn't really tell if that went back right when sliding the print head back into position.

    for some reason i only have like 5 marks of black previous to this i was missing about 5 on black, but somehow got all ports working on blue now, was missing about 5 on blue also.....wtf

    ya its popping the fuse, just tried second one......must be that ground??

    Swap cables from black head to magenta head, If it blows again, head is fried

    black and blue cable make red and yellow head print.....

    My god.....how did this happen?? ribbon is shorted, cant tell if its melted into the socket or not, if it just needs a new cable.....

    didnt even realize the fuses were already piggybacked unitl i blew up photos

    unfortunetly the fuse blows with the cables unplugged.......can a guy actually replace that socket??

    so are there a few resistors or caps to check, found a couple things in another thread.....or am i stuck sending it for repair??

    the cable metal was actually folded over, i straightened it back out, seems ok. I must say i have pulled and reconnected pry about 1000 flat cables in printers, tvs, you name it, this has never happened before......

    Im scared of losing the print heads, right now i have cleaning solution in them, is this ok? I took off the dampers and put lines on the nipples and fed cleaning fluid into the heads, then sucked it through from the pump side. Then put dampers back on so they dont dry out.



    Is this OK?
