I only know from a jv33 that lived like 6 years, not printing 24/7 but with good use.
anyway.
I got a jv33, for 2 years now... and im surprised.
Here, mimaki's supplier is very expensive... and they wont teach you anything about the machine... so if you want to make your jv33 work and make profit of it. you should first investigate, and learn everything about it. (How to change printhead, Service menu important items, disarm everything and built it back again).
Anyway, because mimaki prices here in Argentina, we are thinking to move to mutoh, selling this mimaki jv33, because when printehead died for first time, the replacment cost of printhead, dampers, head cable , pump and cap station was aprox. 4200 dollars + 100 dollars for tech guy. this is mimaki "official" supplier.
Of course you can buy dampers, head cable, and everything from our loved china people, or other resellers.
Im Running a jv33 with ss21 ink sublimation. (MMCCYYKK)
So here is what i think.
Pros:
-Working 7-8 days straight without stopping until printhead died without problems.
-Fast cleaning.
-Fast replacement parts.
-good price for its quality. (when we bought it)
-Mimaki Rasterlink Pro5SG is very easy to use,you can have a monkey run the machine on weekends for you and can reach good colors with it.
----------
Cons:
-Slow printing (4 pass 720x540) 4'30" per meter in a 1.6 meters widht media.
-Very Expensive Original Parts and service tech.
-If using a bulk system with non-original mimaki inks, double ink (MMCCYYKK) settings and auto-jump from one bulk to the other wont work, as mimaki supplier says...
-this machine cant stop printing, if jv33 take a good sleep like 1 week stop, when you need it back you will need to make a little maintenance.
We are looking to change our mimaki jv33 to a Mutoh ValueJet 1628 TD 64" with x2 DX5 Printhead. Anyway i think i will stay with Jv33 because the experience we have with it.
Mutoh is much faster, no more banding, and cheaper spare parts.
Price for a jv33 and ValueJet 1628 is 2000 dollars only. which is non-sense when comparing production speed, and costs.
Hope i helped you.
Sorry for my English.
