Q: What about the print head clogging?

A: Add notes to describe the two kinds of plugging situation processing 1, soft plugging repair: (1) soft plugging refers to a variety of reasons caused by the viscosity of the ink in the printhead due to the breakage of the line failure. Sometimes only attached to the surface of the ink outlet nozzle, generally dipped in the original ink can be restored after several cleanings. (2) use the printer driver application tools in the printhead cleaning function to clean. 2, hard plug repair: (1) immersion method Scope: less obstructed Solution: first find a metal container with a flat bottom, add a little 95% concentration of organic solvents in the container alcohol solution, alcohol to just submerge the print head stainless steel wrapped but do not let the PCB board in contact with the location of the alcohol. Soak time generally ranging from 2 hours to 4 days. (2) pressure cleaning method Scope: the obstruction of the situation is more serious Solution: a disposable infusion set of plastic tubes or needles partially made of syringes and print head between the ink port interface (combined parts must be tight), the interface production is complete, the head of the print head placed in a concentration of 95% of the organic solvents in the alcohol, through the print head of the alcohol will be sucked into the (note that only can be sucked into) syringe syringes, inhalation Several times. The advantage is that the cleaning effect is good. General obstruction of the print head can be cleaned by this method. It is worth noting that the inhalation of alcohol should be even and consistent back and forth, generally does not cause physical damage. Only the production of interface needs to be due to the actual situation of their own handmade, so you need to have a professional maintenance technicians with a certain degree of hands-on ability to do hands-on repairs, the production of a good tool to ensure long-term use.
