Abstract: The ejection positions of a plurality of pre-processing agent ejection nozzles and the ejection positions of a plurality of ink ejection nozzles as seen in a direction orthogonal to the transport direction of a recording medium are in a one-to-one correspondence with each other. A controller causes the process of ejecting ink of a first color from the ink ejection nozzles onto the recording medium subjected to the ejection from the plurality of pre-processing agent ejection nozzles so as to form a failure detection printing pattern which is a printing pattern formed by providing a time lag between the processes of ejecting the ink from adjacent ones of the plurality of ink ejection nozzles. An ejection failure in the pre-processing agent ejection nozzles is detected by judging that a pre-processing agent ejection nozzle corresponding to a region where bleeding results suffers the ejection failure.

Abstract: The present invention relates to a printing apparatus and a cleaning mechanism thereof.A capping unit (302) includes a plurality of caps (301). Among the caps (301), a separate cleaning cap (301a) is connected by a tube (314) having a second valve (312) to a pump (310) for sucking ink from inkjet heads (101). Other caps are connected to the pump (310) by a tube (313) having a first valve (311). At the time of steady state, the first valve (311) and the second valve (312) are kept open to suck ink from all the inkjet heads (101). At the time of occurrence of defective ejection, only the second valve (312) is kept open to suck ink only from an inkjet head (101) having an ejection defect.
