Abstract

PURPOSE:To make the scraping off of the paper powder, dust, etc. stuck to the tip of a nozzle by a simple structure possible, by installing the ink jet head cleaning mechanism of a brushy state soaked with cleaning liquid within the ink jet head transfer stroke getting out of a printing area. CONSTITUTION:In the ink jet serial printer unit of an on-demand type, a cleaning mechanism becomes for instance, of a cartridge structure and the brush 4 cleaning a head 7 is adhered to the rubber cap 2 through which an air vent is bored penetrating it and inserted into the open hole at the upper part of a cartridge 1. Then, the head cleaning mechanism 13 is arranged between the side of a platen 10 and a head cap mechanism 12. When the operation of printing is ended, a printing head 7 returns to the position of the cap 12. Therefore, the nozzle tip part of the head 7 is automatically brushed with the brush 4 of the cleaning mechanism 13 without any special operation at the start and the end of printing and washed with the cleaning liquid 5 soaking in the brush 4.

Conventionally, the print head of this type of printer has a nozzle part, an ink pressure chamber, and an ink supply part formed on the surface of a glass tube or plate using techniques such as photoetching, and is glued to the outer wall of the ink pressure chamber. The bending deformation of the piezo vibrator pressurizes the ink pressurizing chamber, causing ink droplets to be ejected from the nozzle tip. When an inkjet head is used for a long period of time, paper dust and minute dust in the air may adhere to the nozzle tip of the inkjet head, blocking the nozzle hole, or sucking out ink from the nozzle hole with the paper dust and dust as a core. The ink droplets cover the nozzle, making it impossible to eject the ink droplets or impairing the direction in which the ink droplets are ejected, resulting in missing dots and deterioration in print quality.
