I guess you will say the same about your printer... And industrial level printers uses other printheads too - Inca Onset series uses Spectra heads (dropsize depends on required quality). It is an industrial level printer, nobody can deny. And it's a well known supplier (located not in China...

Waveform from the previous head may work (or may not). If the new head have different waveform, you won't get a required printing quality. And check the voltage, 1.95V will not work for sure - it's far too low. Usually heads have voltage around 20-21 volts, but you should get full info about...

For sure voltage shouldn't be above 2V, but above 20V. If you have a new printhead, you should get also information about the waveform of this printhead and voltage. Each head have different voltage to be set, that's why it's so important to set it properly. If you ask about the cyan head...

Search for the Pluto A20 PLC manuals. Error 14 means "Static output Q10..17 (Q20..27) short circuited to 24V" (flashing LEDs shows the affected I/O)). This info is for updated version of the PLC (v2), but I think it may be still valid. If you have short circuit somewhere in the machine, maybe...

I think it was here somewhere (I mean this forum).

Can you check, if all table pins are moving up and down? You should have somewhere option to raise/lower pins manually. Try to do it and look, if any of them is not working.

If you replace the belt with the Stanley tape, it's not needed, you just connect both ends of the tape to the carriage (there are screws there).

NateIn22, next time ask them about the calibration procedure after the head replacement - mechanical adjustment (with the screw) is only one of the steps. I agree, that when the head is located in the proper position (between reference head's stripes), it's possible to print, but optical...

Many reasons - leak in the degas system (on one of the modules, on tube, on pump), damaged sensor, damaged tube near sensor. When you have this problem next time, look at the carriage, if you have ink leaking from degas modules. If not, tighten all the connectors on the tubes in the degas...

Difficult question - you never know, how the ink (or mixture of two inks) damaged the head. Who did the conversion - you or someone from the third party ink supplier? Did you test, how these two inks are mixing together? The formulation of different colour may be different, so two cyans may work...

For timing alignment special software and Epson scanner is required, for the voltage calibration service key is needed (if you leave the voltage from the old head, calibration could be difficult, as the drop size and flight path will be wrong). Some say, that it's possible to change the voltage...

Why you put a grease on the belt? It won't help, the belt moves on two rolls, which has bearings, so the grease won't do anything.

So the problem is somewhere else - did you replaced the filter in this channel? If not, try to do it. If it doesn't help, try to do few purges removing the ink from this subtank, then disconnect the ink tube from the subtank (the black one) and put it inside the empty bottle. Look if the ink is...

When did you replaced the ink filter for this channel? Filters are being clogged in time and the only solution is a replacement. It should be done once per year or after 50 liters of ink. If the filter is clogged, ink can't reach the carriage within proper time. So first check/replace the ink...

How old is the machine? Did you ever clean the mirrors inside the lamps? Does the curing level (and the stickiness of the ink layer) depends on a colour/amount of ink (i.e. dark solids are not cured, light colours are cured)? Is the curing the same in different printmodes? What about the...

You can replace the head mechanically and calibrate the physical position of the head, but it's difficult to set up the voltage and the waveform for the new head, as it usually requires the key. I've heard that some people tried to change it in the windows register file, but I'm not sure, if it...

Fujifilm Acuity with double table - print area is 2500 x 3050 mm. Specific model depends on a budget, but worth to check. Or Inca Onset - 1600 x 3200 mm. But here budget won't be low :-)

A partial solution may be printing unidirectionally with full carriage travel across the table width. Also few seconds pause after each pass may help. But the best way is to use the LED UV printer (like Fujifilm's LED1600), there's no heat under the lamps there.

I didn't mean that longer lightfastness is not possible - but information, that there are some 'niche' products doesn't mean, that they will be popular. There must be a reason that this product is limited, if it would be so good, it could be sold in thousands... I'm always afraid of "special...

UV light during curing starts polimerisation in the liquid ink (that's why one of the components is photoinitiators)- that changes the state of matter of the ink from liquid to solid. Colour change after some exposure to the sunlight takes place in the pigment (which is a different component)...
