The version 2 Mikachips are dodgy at best and when you ask for support, they just try and sell you on their chip emulators. Oops, misread that as the MikaChip 2. Never played with the emulators as they're just arduinos using the 1-wire library.

If you feel like modding the head plumbing, the Gen5 heads are designed to have ink on both sides of the channel. No bloody clue why they added a bleeder port instead of just a Y fitting like sane designers. Then again, they also opted for oddball 4 channel 150DPI heads instead of 2 channel...

I just do manual purges. Take a small syringe, grab a piece of tubing and steal the right-angle fitting from the drain tube. Move head over the wiper station (Maintenance> Station> Station) and gently pull air through the fitting one port at a time pulling just enough to remove air bubbles and...

Run your calibrations as covered in the cutting guide, might help some. Also, check your media compensation settings. https://mimaki.com/archives/034/202410/D203243-19_CJV200,CJV300Plus,CJV330,UCJV300_150,UCJV330_IDCutGuide_e.pdf

If you have a Mimaki dealer, see if they can get you the factory parameters.

Boils down to quantity, durability, lamination, etc? A cheap roll feed solvent printer, a cheap 24" vinyl cutter with registration mark reader and a small laminator will cover most people. However, you'll want to keep the printer going to keep heads clear, take on maintenance and still be in a...

Sounds like a fun engineering problem, but one that might involve modifications to the bed and addition of a larger pump. Not going to be an easy thing to do. The JFX500 has a great vacuum system, but they also have a rubberized bed coating and the ports are counter-sunk slightly. Not sure the...

I've put new thermistors in some heads, and the CE4N heads aren't bad to work on. To my knowledge, the thermistor deltas are hard coded, as there are no normal instances where thermistor type should change. More a Toshiba problem than a Mimaki one, as they make the heads. As for the MKII versus...

Had mixed results with the hot peel, but it's cheap enough that it's great to have on hand for more monolithic prints.

One of the first machines I trained on with Mimaki was the TXF series and I was sorely disappointed with the machine. It's just a JV150/300 with some new plastics on it and some different parameters. Heads are going to get nuked regardless of your DTF setup, the rubberized ink is always going to...

Working on school equipment is terrifying at times, but it's great for finding the weirdest problems and 'fixes' that you'd almost never find elsewhere. Then again, I did just put new dampers in a printer that had zipties and twist ties holding the tubing directly on the head ports. That was...

Been dealing with a lot of DTF as of late, so here's my breakdown. 1) Most printers are based on nearly identical parts, even US assembled ones from most brands. Support will be the major motivator for most people in choosing brands. 2) 13" and 17" are most common widths. Most people going...

We use aftermarket ink, so it's like $45/liter, white, clear or CMYK. Since we're mostly a Mimaki shop, all the printers tend to have 2+ channels dedicated to white, so we can get a good thick pass and color on one go, it tends to be about a 20-30% up-charge. Then again, I just price stuff off...

I think 3's and 5's are compatible, a 2 'might' work. However, note that before moving an EPL board from one model of printer to another, it needs to be flashed with a special generic firmware for compatibility before it can then be flashed to a model specific firmware.

I'd lean towards EPL board, it's basically the motherboard. It takes control input and operates the screen and can run solo as long as it has power.

Yes. if you have staggered heads to allow white to be printed on same pass, not much. If it requires its own pass, much more.

Hold Up/Down arrows when booting to see if it at least goes into Parameter mode. Might be a bad EPL board.

I would run some flush through the system, might just be gelled up ink screwing things up.

Might need to try and find a manual for the stepper driver, some require different modes to do jog tests.
