Mimaki JV3 75sp2 , 2xcmyk dx4 20 questions
JUST BOUGHT IT HAVE YET TO PLUG IT IN, HAVE – SEEN IT PLUGGED IN 2 CARTS EMPTY – HAVE REMOVED HEAD TO CLEAN DX4’S
1. permanent chips, I have to buy 8 2 off each colour cmyk?
2. the cartridges are not forced with pumped air – does something squeeze the bag then?
3. bulk ink systems for them rely on 10 newtons? pressure forcing downwards? or pulling of ink at the capping station
4. Is it best to use the bigger dampers, with adaptors from 2mm to 2.5mm,
5. do I then need the digiprint big damper saddle bracket @ £27
6. could I simply run new ink lines @ 2.5mm straight to the cartridges – would this then lessen the line pressure are cause ink starve, or do it a favor
7. is there a hardware plug in chip reset option, or is the permanent chip the better solution @ £150 for 8
8. are roland, mutoh & mimaki cartridges of similar construction/ chip location
9. there are two ink pumps? does one pull and one push, does one pull the ink up to the dampers through the capping station, does it then go to the waste bottle after the pump i.e. am I fitting new lines from the capping station right to the waste bottle….
10. is there a stopper that sits on the bottle as if so mine is missing ‘what does it look like’
11. never used firewire before, whats that?
12. do I need a rip, what do i need.
13. how much slop is there in the carriage / bar phosfor bronze ‘oil-lite’ bushing
is there one on the top in the middle – is it the same size as the lower ones as the bar is smaller?
14 when you get error 07 – if the head is blocked solid, will this flash up – not I have no ink but previous owner says so, OR is it all electrinics – is it a head over temperature because the crystal cannot vibrate?
15 WOULD IT BE POSSIBLE TO SWAP INTO IT THE CARTRIDGE DOCKING FROM AN EPSON 7880 8 COLOUR, AS I HAVE REFILLABLE ARTS AND CAN RESET THE CHIPS.
its seems plauseable? 2 wires for cart phsycally in micro switch and 2 to read the level – find which pins on the epson correspond——————-
dx4 heads
1. dx4 head cap manifolds, do they have a filter in the disc part – I.E. when I pull and push cleaning solution through them, do I then have to remove the cap manifold between each pull and push session
2. is it best to pull and push with a damper fitted, if so, is it then better to remove the head plate with heads and clean away from the elastitrickery
3. If the machine has had a head strike…. if the solution is coming out from the central part of the head, is it toast?
4. IF as I suspect, my manifold / head cap has softened and broken does that point to it beaing a water based one? and if that is suspected, does that nmean that it would break down inside and clogg the head with molten plastic… – deffo need 2 heads?
5. If I have a 21 pin ribbongoing to the head, does that mean I want 21 jet streams, as that would make sense to me.
6. IS it all about ink viscocity regarding voltage/ranking numbers sent to the heads?
I>E> if someone fitted a water based head to it with the water based number, does that mean ‘if it was set for pigment rather than thinner dye’ the head was given more voltage- do solvent inks want more voltage that water pigment or dye?
which part of the rank number sets the voltage – what do the other numbers and symbols signify
7. am I corrent in thinking its the firts number ‘7’ seven volts, or does it go into another tenth 7.7v – 7.5 v?
8/\ can I set my dx4 heads to fire sk4 ink, is the cruxLAST ONE – DO I TRY AND SQUEEZE AVARY ADHEISIVE REMOVER THROUGH THEM – WITH A HIGH CONCENTRATION OD ‘D’-LENONINE – OR WILL THAT MELT EVEN THE SOLVENT RESISTANT CAPS
thanks in advance

Wow!! That’s quite a post. I’ll try and answer what I can.
1 – You must have 8 cartridges in an SP to be able to fill up
2 – No. They are gravity fed and pulled through by the pump
3 – ???
4 – I find larger dampers are better. Yours should have large dampers as standard
5 – Never heard of it.
6 – Why? JV3’s work fine as they are all over the world….
7 – Suppliers such as Sun will be able to advise on this. I prefer replaceable carts personally.
8 – They are all very similar but the chips and ink will be very different.
9 – No. Pump 1 L is K, pump 1 R is M, pump 2 L is C and pump 2 R is Y. All pull
10 – No, no such thing
11 – Also known as IEEE1394. It’s a 400Mbps industry standard architecture.
12 – Ideally, yes. Whichever one you like the look/price of. I prefer Shiraz.
13 – ??? If they’re looking dirty, clean them. If they’re looking worn, replace them.
14 – Error 07 is normally and electrical fault on the head. Could be slider or mainboard or both but definitely not due to a blockage.
15 – No. The Epson you’re talking about has a DX5 head and is totally different to a DX4. -
1 – It is far better to not take the manifold and gasket off they head as they never seal properly afterwards in my opinion. But yes, the manifold does has a filter internally.
2 – I always use a damper to pull and push solution through heads, regardless of whether the head is in situ or otherwise. I only use a syringe directly as a last resort.
3 – Yep, toast.
4 – Not necessarily, I’ve seen some third party inks cause the manifold to get brittle and snap before. But it is possible.
5 – I don’t think it works quite like that. I believe those head cables just carry electrical signals from one electronic device to another.
6 – Head rank/ID info is about head voltages. I don’t think viscosity comes into it…?
7 – ???
8 – ???
9 – I’ve no idea what that is. But I would always try it on a damaged head first, just in case.I hope some of that helps?

taller bracket holds the taller dampers into the heads?
http://www.digiprint-supplies.com/rolan … 35836.html
get these, big dampers? when they say big – does that relate to the physical size or the bore of the ink line?p.s. thanks
oh and p.s. buying second hand heads….
crap shoot?I’ll have to wait to nuy 3 @ £1500, then probably fry them on initial start-up!!!!

That head bracket is the standard genuine Mimaki one and should have be included in the printer. The dampers are aftermarket but should be OK, I’d do the o rings at the same time too.
Second hand heads can be an option, but make sure you know the history of them and have a recent test draw.

more questions
1. I have bought reset chips dual cmyk and ss2 ink – do I now have to use ss2 ink
2. yesterday I bought a complete epson 10600 for the three heads in it, I know from popping one of the original heads that if mixing water/ipa to first clean them and then solvent cleaner it sludges up – so how do I avoid this? – i did this backwards using avery surface cleaner not realising it was water based!!!!!!! -after solvent cleaning fluid.
3. cleaning carts – I have 8 empty little carts, they have been used with colours in and have chips on – do I need to blank off the chips slots smooth? when you clean with carts, does it not need a chip ?
4. do I refill these cleaning carts with 99 percent acetone or is that too hot?
5. can I switch the machine on with the chips reading full but with no ink in them to first ascertain if the electric work, or will it automatically want to start to pumping ink? what I don’t think I want to do is fill up my clean heads with ink only to find something else doesn’t work……
