CJV30 Help Needed

[Olly Townsend]

Hi all, totally new here and new to printing

Our company has recently bought a Mimaki CJV30-130 for printing posters etc for our own marketing campaigns!

There seems to be some 'over spray' from all colours - this is the best way I can describe it - and also lines in Cyan and Magenta. You can see the over spray most clear on the 'K' pic below

Pics are attached and any help is appreciated?

I have performed many nozzle washes, custody wash, pump tube wash.

Thanks!!

Also note how there seems to be black particles in the yellow print?

Thanks for your reply!!

I do not know the head high or low setting, and I don't know how to check?

Print settings is Bi-Directional, 16 Pass, fast-print off

you need to read the manual when you can! - or go on line and read it!

1- your print head adjustment is on the the moving unit to the right - look up how to adjust and set on low!
2- in rasterlink five set like this!

1- image edit -- (cenetred)
2- color edit -- (rendering 16 bit) (illustration icc) (image icc)
3- print condition -- (pass 16) (uni-direction) (overprint 1 time)

heater should be set 30 - 30 - 40

! what media are you printing on - should be fro printing and cutting NOT cut vinyl?

see if this helps

ALSO
2 things should be done ALWAYS

in the main control panel you will see cleaning (button) - clean 2 times on normal
then also a test print (button) run a test -- that will tell you if your problem is the head!

Ok print quality has improved, however still problems.. pics below.

• still have a black 'dust' over some parts
• cyan and magenta is liney?
• test print pics below

Let me know what you think ?

Thank you for your help

I have looked at head and looks dirty. Can this be problem? Can I clean this with swab?

 

[rvolkers]

based on your test - WHICH WAS REALLY BAD - your head is probably damaged
i would have a professional come in and service the machine - which should include software up grade

there should be NO lines broken on the test print - it should be CLEAN

this is just my opinion - but i would have the machine serviced! - and if the head is damaged
go back to where you got the machine and tell them to fix it! - OR - keep cleaning and let the head soak for a long time!

Ok thanks. How do I let the head soak? Do a nozzle wash and leave it over night ?

 

[rvolkers]

call a tech person! for help on this -- i recommend a service!

Can I clean this with swab?

Did you get a maintenance manual? This machine is to be cleaned daily with frequent work and at the latest, weekly.

Basically, get a swab and the cleaning fluid and clean everywhere except from the actual head (the bit ink comes out).

Looks like there’s a LOT of built up ink so that will take a while and lots of swabs.

Next go clean the wiper and everything else on the right hand side. I.e capping station that silver bit to between the wiper and the capping station.

There should be a little white sponge on the right of the capping station too.

After that, do maybe 2-3 hard cleanings, then maybe a fill up ink.

If you get the capping station clean, when you leave, start a nozzle wash (with loads of cleaning liquid left in the capping station) then turn the machine off at the plug overnight (if you don’t turn it off, the wash will stop after a maximum of 99 mins).

If all of that fails, it could be a new head you need. Or at the very least a good service, new dampers, capping station, pump etc.

Worst case, is I might be able to get the PDF of the manual if you need it. Let me know. I’d get the test print sorted before you do any of the alignments.

Good luck!
