Abstract
A wiper for avoiding ink residues adhering on side surfaces of a print head comprises a main body. The main body comprises a supporting portion, flexible portion, and wiping portion, which are sequentially connected with each other from bottom to top. The wiping portion has a wiping end and a contacting end. The wiping end extends from one side of the wiping portion while the contacting end is positioned on the top of the wiping portion. Before the print head contacts the contacting end, the contacting end is higher than the nozzle surface and the wiping end is lower than the nozzle surface. After the print head contacts the contacting end, the flexible portion bends down so that the contacting end is lower than the nozzle surface and the wiping end contacts the nozzle surface for wiping the ink residue on the nozzle surface.
