No ink flows. Tried all the troubleshooting steps I could find. #54

I'm trying to get my MBrush working. I can connect over WiFi. I can see it cycling between the two test print areas when I press the button. It beeps like it's printing when I move it and lights are green for the duration of the "print".

However no ink comes out.

The device was left for a while without use.

I've used water with a light soak to get the ink flowing. I see a nice C&M with a tissue blotting but Y is not flowing very well. But I expect I should still see something printing.

I think we got something printing out of the device when we first tried it but nothing since.

I've updated the firmware to APP 4.36, FW 4.17. I've power cycled.

I've read through the FAQ to no avail.

I'm not sure what else to try.

Really want to get this working again for my father. He's actually one of the original inventors of the technology in these cartridges! (Yes, he regrets how the business ended up and never saw a penny from their current bs practices)

I'm sorry, there may be a problem with the ink cartridge, or the contact between the cartridge and the printer may not be good, I suggest to try a different cartridge. Available cartridge model reference: Compatible ink cartridges #12

I can tell you what worked for me, after I just about gave up on a cartridge that sat for 4 days.

Wrap the cartridge in a paper towel. Hold it so the nozzle-end is facing away, and swing your arm in an arc/circle pretty hard. The idea is to use increased gravity to pull ink down into the piezo jets. Check the appearance often as ink will come out FAST and soak the paper towel. Could make a mess this way, spray a fan of ink droplets, or just consume a mess of ink in a hurry.

In my case, it 100% cured my cartridge, which was printing no Magenta at all. I think I blew too much air up in it (with a compressed air can) and it wasn't able to flow? Not sure, but it's running great now.
