I'm using DMP 2831 inkjet printer and currently using only silver nano particle ink(NPS-L). The problem is after filtering about 4ml of ink with a PTFE 0.45 filter into a new cartridge and trying to print, it didn't work well(jetting issue) and leaked to entire bottom side of the cartridge. Could the issue be that injecting about 4ml is too much? or could there be another problem?
Also, if anyone has experience using the same ink(nps-l) as me, i would appreciate recommendations for a suitable solvent to adjust the appropriate viscosity. i couldn't find any information about this on the manufacturer's page.
Two different type of inkjets exist.
(CIJ) Continuous flow requires a positive fluid pressure.
(DOD) Drop on Demand generally requires a negative fluid pressure that is overcome when a drop is needed.
Both CIJ and DOD use nozzles with small orifices. Fluid filtration should limit any nanoparticles or agglomerate particles to much less than 1/5 the nozzle orifice diameter.
I suspect your leak is from fluid pressure. Also, nanoparticles can interfere with fluid meniscus behavior and this will cause nozzle leakage.
