Title: Ink jet recording apparatus and cleaning control method of recording head therein
Inventor: TAKAHASHI NOBUHITO
IPC: B41J2/165
Filed: 1999-11-17
Abstract: PROBLEM TO BE SOLVED: To provide an ink jet recording apparatus capable of ensuring the reliability of printing operation over a long period of time. SOLUTION: The moving speed of a carriage 1 to a wiping means 21 after ink is sucked and discharged from a recording head 5 by applying negative pressure to a capping means 6 is controlled so as to become slower than that of the carriage at the time of the wiping of the nozzle forming surface of the recording head by a wiping means 21. Accompanied by this control, the capping means 6 having sealed the nozzle forming surface of the recording head 5 falls at a low speed to act so as to release the sealing from the nozzle forming surface. As a result, a degree of the scattering of the ink stored in the internal space of the capping means 6 to the periphery can be reduced to a large extent. By this constitution, a problem such that the interior of a recording apparatus is contaminated with scattered ink to cause trouble in respective mechanism parts can be solved.
