I am getting a bad nozzle check on the C cartridge of my 9900. I have a head that was newly installed in the Fall of 2013, when the printer was also cleaned. I installed a new wiper in Fall 2013. As far as i know, the printer has its original dampers. I keep a humidity-controlled studio, shake the cartridges regularly, and print frequently, though not in high volume (a whole week almost never goes by without printing). I’ve been using Epson inks since the new head was installed. I had been using Cone Pro inks for about eight months before the head was replaced.
I did several C/VM head cleanings and two power cleanings, to no avail. I would upload an image of the nozzle check, but your forum just gives me a cryptic error code when I attempt it, even though I have a JPEG image that fits well within the rather tight restrictions on file sizes and dimensions.
I hesitate to do more power cleanings, given the warnings Jon has posted about how the 9900-7900 power cleanings are not the same as on older printers. I installed a new wiper in Fall 2013. I suppose that opening up the printer and putting in new dampers, a new wiper, and generally cleaning the interior would help. You most recent newsletter recommended that. it indicated that Inkjet Mall would sell dampers for various models but not for the 9900. Where can I get those?
I think I have the necessary manuals already.
I am also considering using PiezoFlush, both to help clean the head and also to mothball the printer while I am away on vacation. I will only be gone three weeks, but in the future I could easily be away for months.
Could I use my old refillable cartridges for the PiezoFlush? There is still some ink in them, which I can return to the original bottles.
