Inkjet printer with waste liquid tank level detection
A recently granted patent (Publication Number: US11865846B2) discloses an inkjet printer with innovative features aimed at efficient waste liquid management. The printer includes a head with a nozzle for liquid injection, a cleaner to discharge liquid from the nozzle, and a waste liquid tank for collecting the discharged liquid. A support table under the waste liquid tank is designed to move based on the weight of the liquid, reaching different positions to indicate varying liquid levels. Sensors detect these positions, signaling when the tank is near full or at capacity. Additionally, a loader mechanism applies force to the support table, aiding in managing the liquid weight and tank displacement.
Furthermore, the inkjet printer incorporates a unique design where the support table includes a carrying portion for the waste liquid tank and an engagement portion that adjusts based on liquid weight. The base of the printer supports the table and includes a loader mechanism to control the engagement portion's movement. The printer also features sensors positioned to detect specific plate portions on the support table, indicating different liquid levels. Notably, an operation prohibitor function is included to prevent cleaning operations when the waste liquid tank reaches full capacity, ensuring optimal printer functionality. Overall, the patented inkjet printer showcases advancements in waste liquid management within printing technology, enhancing operational efficiency and user experience.
