Printhead of sublimation fabric printer is a kind of precision component with high precision and small nozzle. Once it encounters inferior ink or operation is not standardized, it may cause printhead clogging. Therefore, it is necessary to understand causes and solutions in order to solve problems in a timely manner without affecting progress of work.
 
Causes of printhead blocking in sublimation printing machine
 
1. Irregular operation of sublimation printing machine
If printhead is exposed to air for a long time without working, it will cause ink to condense and block nozzle. Therefore, operation of sublimation fabric printer must be standardized, and a test strip must be printed before each startup to test printing status of printhead; after printing is completed, carriage must be returned to capping station in time.
 
2. Inferior ink is used
Inferior inks use poor quality raw materials, large particles, and many impurities, which can easily block nozzle, resulting in nozzle missing and lack of color in sublimation printer. Therefore, it is recommended that you must choose high-quality and good inks. Manufacturer's original inks are preferred. Ink quality is guaranteed and compatibility with printing machine is better.
 
How to deal with printhead blockage in sublimation printing machine
 
1. First of all, when printhead blockage is relatively lightly clogged, cleaning function of Fedar sublimation printer should be used first. If printhead blockage is serious, you can remove printhead and put it in cleaning solution to soak and clean.
 
2. Secondly, judge cause of printhead blockage according to actual situation, and deal with it in a targeted manner. Gradual nozzle missing during printing process may be due to dirty damper and aging of printheads. At this time, damper and printheads need to be replaced. If nozzle missing suddenly during printing process, and nozzle missing is severe, it is mostly caused by ink, and you need to replace high-quality ink at this time.
