We have owned our machine since March of 2010. We bought ours from Pitman which was a nightmare. They shipped the machine all the way from HP to a warehouse about 20 miles from our building. They then SHIPPED the machine FedEx from that warehouse to us! 3 days later FedEx calls us to schedule delivery, for 2 days later. We told them to hold it (which was now 20 miles away the other direction) and we loaded up in the pickup truck, went to FedEx warehouse and picked it up ourselves. Brought it back, set it up and started printing that afternoon. Then we billed Pitman the $2000+ that we were supposed to pay for install and training. Got a few sets of ink, some media and the bill for install and training (from them to us) was written off by both parties. Then one day, TWO WEEKS later, a guy in a Pitman shirt shows up at my front door and says he's there to install and train me on my machine. Flew in from out of state! Of course he didn't know a thing about my machine and just kept referring to it as a z6100. So we taught him a few things about the printer, went and ate some bbq and sent him on his way.
1.) how many head have you gone through?
We have owned our machine since March of 2010. I replaced both magenta heads back in March of this year I believe. (one of our biggest clients has a red logo, and red everything for that matter) And then last month I replaced all the other heads. They didn't really need replacing, quality hadn't diminished AT ALL and replacing them I didn't notice an improvement in quality or anything, just figured after 18+ months of printing and 61,362 ml of ink it was time to replace them.
2.) How many ink cartridges?
Cyan - 11
Magenta - 19
Yellow - 18
Black - 17
Light Cyan - 10
Light Magenta - 10
3.) What is the longest it has sat without printing?
We went an entire week once with the machine not working when we were all out of town for a job.
3a.) Did it print fine after this time and what did you have to do to get it to print if it didn't just start printing fine!
We came back from out of town, turned her back on, and started printing like she didn't miss us at all! I did to a printhead cleaning but I don't really think I needed to do that.
I can tell you that having gone from a mimaki to this machine, I will never go back to a solvent/eco/mild/bio anything! This machine is awesome!
BTW, we are primarily a vehicle wrap shop and have wrapped a ton of cars off this machine in the last 18 months. Epson sounds like they're in panic-mode there. I would be if I were them...
