发明名称 Ink jet recording apparatus and method of maintaining it
摘要 In an inkjet recording apparatus, when an elapsed time exceeds a first period of time (T1) after the last head recovery processing was executed, a maintenance controller (66) executes a head recovery process based on the result of measurement effected by a maintenance timer (69) when printing is not executed by a recording head (3). Further, if an idle (non-print) period of time (Tnp) continues longer than a third period of time ( alpha ) when it is determined that the elapsed time (Tcl) exceeds a second period of time (T2) shorter than the first period of time (T1), a head recovery process for drawing a predetermined amount of ink from the nozzles of the recording head is carried out by driving an ink suction mechanism (55). With this arrangement, an inkjet recording apparatus is provided in which the time from the issue of a print command to the completion of a print operation is not extended by recovery processes applied to the recording head. <IMAGE>
