In case all nozzles on the printhead are blocked with solidified ink, you're probably better off just getting a new one to replace it.

I could be wrong but it is very likely that all head nozzles are blocked with solidified ink that is why you are not getting any ink at all on the capping unit.

When was the last time you obtained a good nozzle test pattern from this printer?

This can be pressure roller contamination or pre-heat/platen heat setting issue. With an ambient temperature of 24 deg C and 40-60% humidity, my usual settings are: pre-heat 38 deg, platen 40 deg, and dryer 45 deg (+/- 2 on all values as required)

Printheads for the VJ-1604 and the VJ-1614 are the same, as well as the the ones for the VJ-1204, VJ-1304, VJ-1304W, VJ-1604W. Mutoh Part Number is DF-49684

This error indicates abnormal communication between the mainboard and the heater controller board

There is no adjustment for the cap itself, it maybe the maintenance assembly that is not correctly positioned in this case.

I might have missed it but are you using genuine Mutoh Eco or 3rd party inks?

Strange, a faulty sensor on the subtank should result in an error message, I would have thought, :smile:

You can change this in Onyx on a job by job basis or make the setting permanent. If you want to do it on a per job basis, after the file had been ripped, select the job, once highlighted, right click on it then select edit, select printer setting then click on it. On the window that pops up...

Try setting your rip to print Data or Media Width only, not Machine Width, if your it supports that. If not, you can also set the carriage travel on the printer menu setup to this setting. Do this so that the carriage does not have to go to the far left end of the printer.

Please post a photo of the nozzle check pattern, this could be due to deflected nozzles

I would not consider that an almost nozzle perfect nozzle check pattern. Having 2 overlapping nozzles is sometimes just as bad as having a missing nozzle.

Is the cutter able to read the barcode? Is the cutter not reading or not seeing the registration mark? Observe the Epos beam as it tries to read the marks. If the beam is on top of the mark, then it not reading it but if it does not go over the mark, obviously it won't even see it. If is the the...

Try to use the Wow patterns, these were supposedly created to fix vertical banding issues. Also try playing around with the temperature settings of the profile you are using, set them lower then higher and see what effect this will have when you print the same file.

Most likely due to the cap unit not sealing properly. What happens is each time the printer does a cleaning cycle, the ink count on the chips will reflect that (go low) but the ink is not being drawn out of the cartridges. The ink count on the chips eventually show empty even though the ink...

this normally indicates that the printer is not receiving any feedback from the CR Encoder sensor, also check if the head lock mechanism is releasing the carriage when it is supposed to.

Do that only after you have backed up the printer parameters, otherwise, bad move. Once you reset the NVRam, your printer would lose all its parameter data (head ranks, uni and bi-di adjustments, etc...) and may not work at all.
