Removing the white bags daily may cause the damage of the ink pouch ports, they are not intended to be used this way (even maintenance procedures were changed due to this). Move the ink in the pouch without removing it on a daily basis (this is what the procedure says), remove the pouch only...

Error 63f means "Calculated ink usage does not match the level of subtank sensor". It may happen, when: - the ink bag is empty - ink pump for this channel doesn't work (broken pump cover, damaged ink tube etc.) - "Sending adjust" procedure wasn't performed (according to the procedures it should...

Pigment size is one problem - depending on the ink system ink should be developed for specific heads (or nozzle size), but the white pigment is heavier than any other (it contains titanium). That's why white ink always likes to stratify and many printer developers add circulation system for the...

What about the Fujifilm? They should sell you QV017, that's the flush solution for Acuity.

Try to swap RFID boards between sides, it's pretty easy (but do it when the machine is shut down). If the problem stays on the left side, it's related to the RFID board, cables or inks itself. If it moves to the right side, it's the RFID board.

Of course, the pump may be weak/damaged too. Find a piece of a tube similar to the one used in the pump, disconnect the original tube, connect yours and check, if the sucking is stronger (but not on the head, try to suck few drops of the ink from any flat surface). If it is, you have a problem...

During the installation sending adjust must be done five times. Each time calculates the flow better.

Which channel shows the problem? Does it happen on all substrates? Does it happen on the paper? How old is the machine? When you did the 'sending adjust' for the last time? Is the negative pressure in the ink system correct?

It's clear that you have no idea about the Arizona flatbeds. These machines use so-called 'coolant' to heat up the heads and keep them in proper temperature. UV lamps are cooled with the fans.

Did you replace any heads recently? When last calibrations were done? Which calibrations? If the printer is 6 years old, heads may be weaker than before, so calibrations may be required. 550 also have one calibration, which is a pain in the a** - density. Is the banding related to any...

If possible, check the log - if there are connection errors between mainboard and carriage, it may suggest damaged Firewire cable. Look at the igus chain and check the ink ribbon and coolant tubings, they wear out in time. Depending on the model ink pumps may wear out too (look under the pumps...

Do you mean 1600? It's made by Mimaki in Japan. The bigger one - 3200R - it's made in China indeed. And it's not as good as 1600.

Absolutely NOT!!! Fuji Acuity (all flatbeds) are made by Oce in Canada. Don't spread fake news, please.

All pictures show just one alignment - head alignment gantry direction. Seems that you have K3 not in line with K2 (which is a reference head for mechanical adjustment). You need to adjust each colour's first head to the K2 then each second head from each colour to the first one (except black...

When the head popped out, shims could fall off, so after pushing back it may not be in the same position. Regardless of this (I don't know if you have your printer shimmed or not), you need to check the software calibrations, as the physical movement of the head always affects it. Scanner (not...

Do you have any error messages? Anyway, ask Oce for visit, do not purchase the board. If they replace it and the machine will work, you have the solution. If replacement won't remove the problem, you won't buy the board...

Any more technical information about such options?

Having knowledge about the part itself is not the same as having the maintenance/service procedures (and I'm pretty sure that DP cannot circulate excerpts of the service manuals - they are available for trained service engineers, at least for Arizona/Acuity machines). But I'll give you the...

365 was "current" a few years ago. Then were 4xxx models and since at least two years series 2x/3x is available. And UV lamps in 365 are different than in older 350, it's not possible to swap parts from one model to another. A lot of other parts are similar, that's right.

How could Digiprint Supplies (spare parts seller) provide you with the information about the head replacement? They sell parts to many different machines, do you think they have engineer manuals to all of them? No, they just have parts. It's up to you to replace the part.
