Use dummy cartridges if you have them, remove the ink cartridges then install the dummy cartridges to seal the needles and prevent ink flow

See attached Mutoh Technical Bulletin Bearing Raceways Maintenance

Please see attached screenshot from VJ-1324X Maintenance Manual

Use the head adjusting cam to rotate the printhead as required

Have a look at the video below:

I just did a quick Q4 (720 x 1440 8 Pass Bi-Directional) profile in Onyx on our XPJ-1641SR using mostly default automated settings, it came out slightly better than the canned SAI Flexi profile.

The printhead fuse on the mainboard is normally labelled F2 and is rated 750mA

Please see attached screenshots, when using genuine Mutoh valve dampers, you need to flush them with cleaning solution before inking

The printheads may look similar but are not exactly the same

I see! Make sure you cartridge is not expired, if is is in date, you may have a faulty valve damper for the Cyan. Were the valve dampers replaced when you changed the printhead? If so, were they genuine Mutoh parts?

February 2021 means the ink had already expired by more than 2 months. I find it is safe to use Mutoh UV ink up to one month past expiration date but after that, all sorts of problems can start showing up.

Are you using 220ml cartridges or the 800ml ink bags?

Thank you very much for the heads-up. Can you please tell us the expiration date of this Magenta ink bag?
