The photo is not very clear but it looks like overspray to me, what is the printing direction of that sample?

When EPOS scanning, the diagonal scan will be executed at the set cutting speed in the firmware (user controlled) while the horizontal scan will always be at maximum speed (100 cm/sec).

The rear part of the maintenance unit is screwed to an angled bracket. Undo the 2 screws holding that bracket to the mounting plate and the whole assembly can be taken out. Then you can unscrew the screws from underneath.

The VJ-1204, VJ-1304, and VJ-1604 share the same motherboard so all you have to do is install a VJ-1304 firmware on that working VJ-1204 motherboard.

Looks like the printhead slant adjustment is out. This is why magenta prints above the black instead of being in line.

This error could have been caused by unstable power supply in your building

Is this problem occurring only on one particular Cyan channel or on both? If always on the same channel, the problem might be on the head's ink manifold. The nipple, where the damper sits, could be partially blocked or even be damaged, possibly a hairline crack or something.

True, I find this happens occasionally. Sometimes due the head rank not being correct because the printer's NVRam had been reset for some reason or another, or just due to normal wear and tear on older printers. Btw, I am also from the Philippines

Assuming you are using original Mutoh dampers and inks, the cap is probably not the issue since you only experience ink starvation on the Cyan. The cap is there is to seal the head and prevent the ink drying from out on the nozzles and also to draw ink from the printhead when doing head cleans...

Yes, it has 2 locating pins and 4 locking tabs that just click in place, no screws. For easier removal, unscrew the clamp that holds down the ink tubes on the CR Sub-board. This would free up the ink tubes to give you more space to wiggle it out.

This is an old printer and I am not sure which hidden menu sets the machine size but you can try switching the printer off the press and hold down both the Up and Down buttons as you switch the printer on. If that is not the correct menu, try holding down the Cancel button as you switch the...

Temporary solution if you have this problem, clamp the waste ink tubes or pull out the ink cartridges after the printer had been switched off.

Generally, you replace the head when it can no longer provide the quality you desire.

Does color ink pass through the head when you do a clean? The gap between the printhead and the platen should be between 1.37mm and 1.42mm.

If nozzle check pattern is perfect, this is most likely a profile or media issue

The first generation VJ-1608 introduced in Australia did not have heated air.

I have customers using rolled tissue paper or paper kitchen towels, this is just to prevent the ink from sloshing about in the waste ink tray. You will need to empty the tray more often in this case.
