To refill the dampers on your Epson ET-8550 after replacement, start by parking the printhead on the capping station. Turn on the printer and let the printhead settle naturally; this is completely safe to do while the power is on. Since DTF ink is thicker than standard ink, it might require some extra effort to get things going. Once parked, connect a syringe and tube to the printer’s waste line and gently draw 2 ml of air. Start by drawing 1.5 ml, where you should feel slight resistance. If you only draw air, the printhead may not be parked properly, or the capping station seal could be leaking. Total resistance without any ink flow likely means a clogged capping station, which you’ll need to address before continuing.
Once you’ve successfully drawn 1.5 ml, listen for the damper membrane crinkling—this indicates the nozzles are open. Slowly continue drawing up to the 2 ml mark, ensuring the black rubber seal passes this point, and hold for 10 seconds. Afterward, run the printer’s standard cleaning cycle, but avoid the strong cleaning feature for at least 12 hours, and don’t perform consecutive cleanings without letting the printer rest.
Another approach is to use a syringe filled halfway with ink. After parking the printhead, connect the syringe to the damper’s input and slowly draw air out before releasing the syringe, which should pull ink into the damper and prime the printhead. Alternatively, reinstalling the printer driver and selecting “No” during the ink charge setup dialog can initiate the built-in ink charge process. Keep in mind, though, that this consumes a lot of ink and may put additional strain on the printer.

В чём может быть проблема? Не герметично прилегает демпфер из-за уплотнительной прокладки ? или в самой печатающей головке
