How to Use Compression Damper on Mimaki Jv33 that There is no Air in Damper?

The ink line at any particular damper will not flow FREELY, due to the fact that the mimaki jv5 or jv33 has two valves that normally closing. One sitting at the end of the ink cartridge which control ON/OFF or OPEN/CLOSE by the reading of the ink chip, and the firmware respond to the open/close by the command send by the firmware. By moving carriage out to the left bay, with empty damper in the ink line, pushing that circular disc actually making the ink from the line flowing into the damper compression chamber, but the ink actually never flowing out from the cartridge since the valve is still on CLOSE position.

So by doing the process as quoted above, you actually making your ink line compromising the pressure which already established prior within the line from the end of the cartridge to the nip tip top of the damper connection, and when compression chamber filled with ink from the wrong doing; the re-compression process will need to be re-establish, and often or sometime if you LUCKY, the ink line compression may get back to operational but never normal and never to peak performance or imperfection but under goes unnotice; until you have a high speed printing and that when the ink compression start to give you the not-so-tight compression and dripping inks all over from the printhead at later time.

At the slow speed, this compression problem may be just o.k. to get by. The Mimaki original tech do have this sequences in the process of changing the damper properly without loosing the compression; but they won't tell you since they want $$$$ in service calls. Most tech doesn't even understand this compression method in the ink system completely so they installed it with the compromising compression level; which is o.k. to print time to time, but Mimaki JV5 and JV33 can print at the Stunning Speed with quality using a particular 3rd party inks with a bit more vehicle in the ink fluid. Original OEM ink tend to be more glueey and more sticky of the ink fluid so that would work with some damper install incorrectly for a while until the ink dropping in/out then became significant a the later time.

The secret, there is not secret; You can do whatever you want, but NEVER compromise the fluid compression between the back-end of the cartridge valve (on-closed position) to the nip tip of the mimaki damper.
 
This nipple tip of the damper also acting as a valve to lock the fluid until is push in and twist, that when the ink can flow out freely but that also already compromise the pressure within the line from 1st valve (back of cartridge) to the 2nd valve (that nipple tip of the damper)
