Hello! I have a technical support question that I'm hoping you can help with and/or point me in the right direction with regards to which part I need to order. I was having a repeated Cyan printhead failure (after 2-3 feet of material) a while back and noticed air in the line, so I tried priming the tubes with no success. I've recently purchased a new ink system from you, and installed correctly using another new cyan printhead, and again, it's failed after a few feet. I've gone through 4-5 cyan printheads at this point, and just can't afford to...

We have received Error Code 010030 034c95a consistently now regardless of the outlet into which it's plugged. I've tried it in different circuits in two different rooms – even our surge-protected emergency outlet. On a couple of occasions the printer has also displayed 0b000a 030f053b and "Check Cleaner Path." These have appeared only a few times out of the thirty-or-so restarts. I'm wondering if you have any suggestions, otherwise it's looking more like I'll have to call a service company. Which is too bad because the ones in our area are not great. I'd appreciate any help you can offer....
