Abstract:
1. An inkjet printing device, comprising: an inkjet head that ejects ink onto a substrate; and an ejection restoring system configured to restore the inkjet head to a normal operation, the ejection restoring system including: a sucking device configured to contact a nozzle surface of the inkjet head to suck the ink from the nozzle surface; a sucking device moving mechanism that moves the sucking device toward or away from the nozzle surface; a wiping member configured to wipe the ink off the nozzle surface; a wiping member moving mechanism that reciprocates the wiping member so that the wiping member wipes the ink off the nozzle surface; and a driving system that drives the sucking device and the wiping member through the sucking device moving mechanism and the wiping member moving mechanism so that one of the sucking device and the wiping member is not driven if the sucking device and the wiping member interfere with each other, wherein the driving system includes: a first position detecting system that outputs a first state signal indicating that the sucking device and the wiping member interfere with each other and outputs a second state signal indicating that the sucking device and the wiping member do not interfere with each other; and a controller that controls at least one of the sucking device and the wiping member based on an output of the first position detecting system.
