  • Cadet not printing black

    Posted by Phill Fenton on July 13, 2012 at 7:12 pm

    I have just returned from holiday to discover my Cadet printer is not printing black. Before going away I followed the procedure for a lengthy shutdown and flushed the machine out with cleaning fluid and left the head soaking with the outlet pipes clamped. Went in this evening to check everything was OK and flushed out the cleaning fluid with ink again. On doing a test print I was dismayed to find that black was not printing. Ran a few more powerfull head cleans and tested it again but it’s still faulty.

    A few years ago I had a similar problem on returning from holiday to find one of the ink colours was not working. It turned out to be a faulty damper, and was quickly fixed. I’m hoping this is the same again, but can’t understand why a period of downtime would cause a damper to fail?

    Any other suggestions as to what could be wrong?

    so to clarify…. the head is full of black ink and nothing get’s squirted out and using a syring on the pipes showed resistance when being used?

    did you leave it switched on or does doing it that way is not required

    Hi Chris – No it was switched off while I was away.

    Dave – I came in today and discovered that if I switched the ink supply around by plugging the cyan damper into the black head and vice versa the test print printed cyan ink where there should be black and no black ink where it should be cyan. So the fault lies in the black supply line up to the head and not downstream. So either the damper itself is at fault or the ink supply up to the damper. I disconnected the tube feeding the black ink up to the damper and pulled some ink through with a syringe so now I’m pretty sure it’s not a blockage in the ink supply tube but the damper itself that’s at fault.

    Will order a new damper and hope this will effect a cure

    good work so far, have you tried pulling the ink through the damper. as there are very fine filters in there, and the flush may have dislodged bits of rubbish.
    if you think its blocked you could chance back flushing the damper with fluid. till a new one arrives.

    Good idea Chris. I’ll try as you suggest and gently reverse flush some cleaning solvent through the damper tomorrow as I won’t get a new one until Tuesday now

    sorry, been away down south the past few days so never spotted this.
    i have some dampers in stock your welcome to phill.
    had some issues the past week or so but decided to go ahead and get a couple of new heads. not bad seeing i think the ones we are replacing are about 4 years old! 😮 :lol1:

    yes i know this is well by due time but have to say, other than these two the rest are still perfectly fine on our grenadier. could it be the change to colorific bio-ink years back now? certainly lasting the test of time.
    have a technician coming in so will ask him his professional opinion on the machine of its age.

    hope you get sorted quick phill. nothing worse mate.

    Oh Dear Phill
    Sounds like you’ll be working in the unit on Sunday instead of putting your feet up and enjoying the weather

    Did as Chris suggested and reverse flushed the damper but the problem remained.

    New dampers arrived this morning – fitted a new one and hey presto problem solved.

    Conclusion – the fine filter inside the damper was probably blocked preventing the flow of ink.

    hi phil

    Hi Colin

    I’m using colorific Bio and have been for the last few years since B&P ceased trading. Prior to that I used Colorific Elite. Is it the Elite or Bio ink that you are concerned about?
