Need Help Mimaki error 190

[HyperGeil]

Hi everyone,

And great to find a forum that welcomes newcomers

I have a Mimaki CJV300-160 it got for a bargain from a company.

It is a 2019 model.

In the display when starter it shows:

Error 190
Main PCB V41-1

Anyone have an idea about that error?

Might be a bad EPL (main board), could be voltages, or disconnected wires. Does it ever boot, or does it throw the error immediately?

I always end in the error.

I actually found the Maintenance Manual, and it have a lot information to check - especially some fuses and leds on the main board.

So I will start there - and then found out the error is a fault in the 42V supply voltage - so will try to check that out too

But hoped someone were able to point it closer maybe.

The power supply voltage is adjustable, so hopefully it just needs tweaking. If not, those TDK Lambda units can be pricey buggers.

Oh yes - the PSU can be sourced in Europe for apx. €500 so not some you just replace for fun

I am also getting this error. I was printing and it stopped mid print. Machine totally froze but was still powered on. I had to reboot the machine to do anything and it came back with this error. I have a video of my machine booting with the error.

Exact same error - what I have found out it that many of the Mimaki models share parts.

And on the PCB there are some specific fuses and LEDs that can blow, if fx. external power is unstable.

My hope is over the next days to have time to measure the components on the PCB and hopefully find an error.

What I have found is that the error refer to 42V supply voltage for the main PCB (EPL2).

So I keep you updated here, when I have news

Hi, did you solve it ?

Hi, did you solve it ?

Well, have had the project hanging. But have some clues.

1. Check the PSU’s - both
Check that the 42V deliver 42V precise on both outputs. One for the EPL and the other for the IO board.

Check that the 5V is delivering 5V precise. Why?
The 5V PSU is among other things operating the relay on the EPL

2. Check the LED’s
What LED’s is lighting up on the EPL and the IO board?

3. Check the fuses - all of them

I have from a couple of projects found three weak points.

1. The relay on the EPL
2. The chip on the IO board ensuring 42V
3. The fuses
