2. The print head is not easy clogging also because sublimation ink particles is very small, also the printer head have damper, the damper have Filtration function, if the particles is large, will not pass the damper the ink through the damper particles is very small, will not clogging the printer head. 
The damper also need clean regularly if long time printing, the damper will also dirty, then the ink can not pass the damper, the printer head not have ink will think it is the ink problems, but sometimes is because the damper is clogged, so please clean the damper at first after clean if still clog, you can change the damper, damper also need replace regularly.
