Advice on cleaning around Mimaki print heads please?
Hi all…
Bought a jv3160s a few weeks ago..
Trying to find out how to clean around the printhead.
I know on the newer jv33’s u can move the printhead to the left and remove a
cover to gain access.
Can this also be done on the jv3160s?
If not how do you guys go about it..
Regards..

Thanks rob….
Already seen this but its different from the jv3.
I don’t think the jv3 has the panel to the far left like this does.
The guy i bought it off said to me not to be afraid and get a cloth under the heads and rub back and forth.. not sure about that!
any help appreciated.

I think the early JV3 does not have the access panel……SP model does.

I have roland machines mate, so cant comment on the process with mimaki, hense why i did a quick search for you.
personally, i would use some swabs and cleaning fluid as opposed to a cloth.
that said, we were told to use a lint free cloth on our uv flatbed heads but ide "imagine" them to be a bit more robust than that of a injet printer. i could be wrong of course but not something ide advise.
anyway, swabs and cleaning fluid. not expensive and can be bought via digiprint supplies http://www.digiprint-supplies.com/
4% discount to uksb board members, see advert code on homepage.as for the actualy process on a mimaki, i cant help there mate, sorry. is there not anything located on the mimaki forums? pdf downloads or the like?

Peter Normington has just informed me that the cover on the left side does come off with the help of a mirror for cleaning.
Will give this a try tomorrow..
Thanks anyway rob…

the 160S, which I have got rid off… there is no access panel…
the right hand side silver panel above the heater switches does come off, you gain a little bit of room to get some cleaning tools in there. You will have to get some long cotton bud sticks and use them but it is difficult to clean the back.
My method was a little bit more harsh… i would undo the head off the two screws and lift it off, this allowed me to clean them easier, but you need to have an engineer mindset to do that.
The SP fixed these problems. The S was the first model.
-
Dave which 2 screws are you referring to?.
Is it the 2 that keep the cover on the printhead?
-
when the print head cover is off… u see the two black coin screws, under them is some fragile (easily broken) screws that just hold the carriage onto the back plate.
I take this off…. then the whole thing lifts up… BUT, i do take all the other bits off like the Thick/Thin selector and the metal bit on the front and the capping holders, but when u done it hundreds of times, you get used to it and can turn a 50min job into a 20min job.
BUT… this is engineer level… there is a 50% chance of screwing up the machine
You supposed to clean with the long swabs… u can get a little finger in.
Also doing the edges is only hald the problem to getting a good seal

Thats exactly how i do mine… just be aware when moving the thick/thin lever that you don’t damage the ribbon cables to the heads.
-
so i have to lift the actual printing head off its carriage and turn it round to access the heads…
Is this right?
-
yes… your risk tho.
-
What are the risks?
Not assembling it together correctly or damaging components such as printhead.
Should I leave it alone or is it a must I clean this area..
-
you are asking a lot of questions… which means your nervous.. i had an engineer show me the basics of the machine when it was out of warranty..
i would have not attempted the procedure within the warranty as I could have easily damaged the head/ribbon cable.
One thing.. it will not go out of alignment.

New area for me. Been using vinyl cutters for years and only just got this printer. U hear horror story about printheads and how delicate they are and costly to replace. Keen to learn and keep this clean and tidy. Nervous would be a correct way to describe screwing it apart. But if it has to be done then it has to be done.
So ribbons are the main components to damage doing this. How often would u say this has to be done.
BTW thanks for ur time.
-
whatever u do…. do not plug the ribbons in to the WRONG sockets… it will be dead

This is a very risky process as has already been mentioned. Before attempting anything like this, it would be safest to unplug the power and then switch the standby button on and off a few times to make sure the green light stays off. If one of those head connectors shorts, it could be bye bye mainboard/head and/or slider (££££). It DOES happen!! Another handy thing to do is to get hold of the service manual and exploded diagram for your printer and digest that so you have a fighting chance of knowing what to look for.
An even safer option would be to get an engineer to give you some nuts and bolts training on the machine to show you the do’s and don’t’s.
Good luck with whatever you decide and be carefull. Let us know how you get on.

How are the heads printing on your JV3? I have found with mine I could get in there and do a reasonable job of cleaning the heads with just the buds and flush fluid. Without having to dismantle the heads. Just make sure you do it on a regular basis so the ink doesn’t have chance to build up. Prevention is better than cure.
Mine is 7 yrs old and I picked it up secondhand a couple of years ago. That’s not to say you won’t have to get under the hood at some point, they are temperamental buggers to run.

the handle end of a cleaning-bud stick is good for the sides
