A recording apparatus is disclosed which is improved in operability by linking a printing head protection device with a switch mechanism. The printing head comprises an ink jet head and the switch mechanism comprises a power source switch, print switch etc.
An ink jet head capping device provided in an ink jet printer has a cleaning mechanism which performs a brushing operation to remove or wipe ink which has leaked out from an ink nozzle of an ink jet head during a suction operation and which is present on the ink jet head face, and to scrape deposits on the ink jet nozzle and the ink jet head face, which would cause clogging of the ink jet head.
A small size ink jet printer includes a cover which presses against the ink nozzle openings when the printer is inoperative. The printer head is electrically driven but operation of the nozzle cover is at least partially performed manually. Particularly, the nozzle covering operation which needs a large force, is often manually performed to conserve energy and reduce component size. Circuits detecting and responding to an inadvertent failure to cover the nozzles are also provided.
An ink jet recorder has a head assembly removably mounted on a recorder body, said head assembly having a plurality of head elements each including a plurality of nozzles arranged widthwise of a record sheet, and a removable cover for covering front sides of said head elements, comprising a connector for electrical connection with the recorder body removably mounted on the head assembly by a lever, and a knob mounted on the cover to mechanically engage or disengage the head assembly with or from the recorder body, the cover being constructed such that it cannot be mounted unless the lever is in a position to disconnect the connector.
An ink-jet type printer includes a unit for drawing an ink from the tip of a recording head, a vessel for collecting the waste ink drawn by the drawing unit, a chamber for detachably receiving the vessel, and a unit for permitting the vessel to collect the waste ink when the vessel is mounted in the chamber and for inhibiting the vessel from collecting the waste ink when the vessel is not mounted in the chamber.
