Background

The ink-jet printer sprays color liquid ink into fine particles through a nozzle onto printing paper, and some ink-jet printers have three or four printing nozzles so as to print four colors of yellow, magenta, cyan and black; and some of the ink jet printers share one spray head and perform spray printing in four colors. Ink jet printers are widely used in life. The ink-jet printer has a printing state and a non-working state; when the ink-jet printer is in a non-working state, ink in the nozzle is easy to solidify to block the nozzle. In order to prevent the ink from solidifying, the nozzle is generally moved laterally above a service station installed on the side of the printer, and an ink sealing strip on the service station is used to seal the ink jetting port on the nozzle, thereby preventing ink leakage and ink solidification. However, the transverse movement of the nozzle has the following disadvantages:

1. the occupied space is large; 2. more sensors are needed to be matched and positioned during resetting so as to ensure the resetting accuracy, the sensor is arranged to increase the manufacturing cost of the printer, and the situation of inaccurate positioning can still occur.
