Title: Ink jet recorder
Inventor: TSUKADA KENJI
IPC: B41J2/185
Filed: 1997-11-06
Abstract: PROBLEM TO BE SOLVED: To prevent poor printing from occurring by controlling an ink suction speed to a proper value when a recording head is cleaned. SOLUTION: A cleaning control means 22 sucks recording heads 7, 8 by a cap member and discharges ink. The cleaning control means 22 is structured so as to change the frequency of a driving pulse given to a pump driving motor and thereby makes it possible to change a speed at which suction pumps 15A, 15B suck ink in stages or continuously. Therefore, as bubbling of ink in the cap member due to cleaning and backflow of bubbles into a head nozzle can be suppressed, it is possible to control an occurrence of poor printing.
