Even for authorized technician, if they installed JV33 or JV5 printhead onsite; the print head may not accept frequency from the motherboard's controller; or in fact, some genuine print head might actually fry the motherboard itself! If this happened, either the manufacturer or the authorized dealer will be responsible for it as a likely the scenario.
For anyone who buying their own print head, and do it on your own; consider yourself a GENIUS
Either that or a very risky business minder. And for any one who's already entitled GENIUS as described, please do tell
So, back in basically October about a month before manufacturer warranty was up we had a pretty nasty storm in Indy and the lightning didn't even hurt our surge protector/battery back up: however, it carried it's nice little self into my print computer, CG 130, and jv33- So, call up grimco support ... warranty hoopla.... ya, ya, ya. tear down computer, new hard drive and motherboard, re install finecut and plotter works just fine, but printer is zapped. error 50 if i recall correctly and the head memory is bad. they send out new head and head memory from mimaki. install, prints about 40 sq. ft. - bad head memory again. call grimco, new head, head memory and motherboard, grimco proceeds to tell me that normally whenever they see head memory go out the motherboard is bad also. i'm upset they failed to tell me this first time around. install new head, head memory, new motherboard. nothing. call grimco, send out new motherboard, head, head memory, other miscellaneous boards for motherboard, boards that go behind inks, and 100% of cables. They proceed to tell me when head memory goes bad, they normally send a new head, head memory, motherboard, and all wires- again, this is an issue they had not discussed w/ me two previous times. at this point in time i am a week and a half out of printer. finally get all my stuff, and put it all together. grimco wants me to pay $1400 for them to come out and adjust printer after i've already put in all the labor on tearing my whole jv33 apart and putting it back together. they want something like $65/hour for drive time from and back to st. louis. No thank you- I then read the full manual on this printer, and go through the process of finding a magnifying glass powerful enough which i am evidently incapable of doing and then decide to use a Cannon 75-300mm photography lens to acquire magnification and to set printer back to crystal clear print quality.
First lesson is, if you want a job done right do it yourself.
Second lesson is, you get what you pay for.
This means that when you spend money on the right parts, you get better results. I could save a fifth by going with plug and play inks, however I have ran this machine strong for a year and a few months, and have not had to continually replace dampers and heads, and have heartache and nightmares about what the printer might do each day.
