the ink is based on glycol ethers. here's some links http://www.wide-format-printers.org/eco_solvent/162_Eco-solvent_printers_glossary_mild-solvent_lite-_bio-solvent_latex_ink_reviews.pdf http://www.jetbest.com/download/MSDS/SP+%20ink%20MSDS.pdf for starters, i've heard of sodium hydroxide...

i'm not a mutoh guy. but because the black pump easily pulled color from that cap, the sponges have to be ruled out ...if the fluid drained away quickly that points away from there being a clog just under the cap. everything points to the color pump isn't doing well. if when hooked to the...

so you've got something wrong with the color pump. here's this tutorial. one thing you can do is take the cap line off the color and put your finger on the end. rotate the pump gear the normal way that the gear turns when pumping, you should be able to feel the suction. also, when...

do you have a spray gun. but a teaspoon of ink in the gun. spray some media cut from that exact spot and see if the ink behaves the same way. looks like you have some oil or wax or something messing with the dyne.

so you got color pumping with the black pump line? that means: the heads not clogged, the seal is fine, and the color pump side is not working well. without the sign of bubbles when pulling with a syringe, we know you don't have an air leak at the cap or cap tube. was the color pump able to...

well, it seems doubtful that the lack of ink is the supplies fault. if the membrane relaxes that means that then ink is also relaxed. the ink in these machines is a siphon, meaning that the chain of ink is falling out of the head. so it has to be relaxed. yeah if it were my machine, i'd want...

there will be a certain amount of air in the lines as you pull the ink. what you don't want is continuous air. when you syringe pull ink into the damper. does it seem to be under a lot of resistance or does it flow evenly? and does the polyester membrane on the damper relax after the syringe...

tomorrow there will be some really smart mutoh guys on here. i figure you do have a problem at the head it self, if you are getting flow through the heads it's doubtful that they are clogged bad enough to print nothing (when you are doing the head cleanings, are you getting good fresh ink in...

hey my 12 year old daughter calls me "old man"... i prefer "kid"! my girlfriend is 26... so around here, i am revoltingly old.

a liter has about $5 retail in solvents... if it were coming from 55 gallon barrels, maybe $1 or $2.

no problem, tomorrow there will be a lot of very knowledgeable mimaki owners on this board.

if the solution is dropping down into the system, to do a good solid head soak, i'd pull the union that connects the caps to the pump. force cleaning solution down through the pumps so that they don't gum up over night. then block the bottom of the cap tube and fill. you want that solution in...

when you pour cleaning solution into the cyan and yellow caps does the solution quickly fall away or does it fill and sit there? also, when you were pulling ink into the dampers, did it seems to have some resistance and did the membrane on the damper relax? i guess you already did a head soak...

first, what ink set, double cmyk? also, is there ink in the caps (does it look wet or dry), is it very wet under the removable caps, if you fill the caps with solution and run a soft clean, does the cleaning solution disappear? when you say you checked the pumps, what did you do to check...

the question is not "what will clean off the ink without damaging the printer". of course alchohol can dissolve the ink without doing damage. but as solvents go it evaporates too quickly. the idea is to dissolve the resins in the ink and not let them re-dry quickly. rapid evaporation can...

it's butyl cellosolve, and acetone. you can add butyl carbitol but i don't. i like it better with just the two. about 4/1 ratio. but don't use it if you don't have a knowledge of solvents. and keep a bit of the factory solution to use as a standard to compare strength. the same base can be...

those patterns are most commonly a data issue. bad head or loose data cable.

did that version of ergosoft have texprint?

well, it does sound like some kind of strange issue. i'd play with carriage speed to see if you can get better results. there is one physical dynamic with these printers, just like the pump is peristaltic so are the ink lined in a way... kind of, with the moving back and forth across the...
