摘要： PROBLEM TO BE SOLVED: To more quickly catch deviation of a delivering position when a printing head moves. SOLUTION: In an image forming apparatus, a printing head inspecting device 50 carries out the operation of delivering electrically charged ink droplets from a nozzle 23 towards an ink receiving region 52 while moving the printing head 24 in the forward travel direction and the return travel direction, from a first region 52a to a second region 52b. A voltage detected in the receiving region 52 during execution of the control becomes a different value at a boundary position P of the first and second regions 52a and 52b because distances from the printing head 24 to the first and second regions 52a and 52b are different from each other. The deviation of the delivering position of ink of the printing head 24 to the boundary position P is caught on the basis of the voltage. A delivering timing of the ink to prevent the deviation between nozzle arrays 43 or a shift between the forward travel and the return travel is set. Printing processing is carried out by using this delivering timing. An inclination of the printing head 24 during moving can be also obtained. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To quickly get a grip on dislocation in the arrangement of nozzles of a print head. SOLUTION: The inkjet printer 20 has print head inspection equipment 50 which detects induced voltage caused by the arrival of charged ink droplets at an ink receiving area 52. The ink receiving area 52 is divided into a first area 52a and a second area 52b, interposed by the transfer side edge 63 of an inspection plate 60 as a border line. The equipment detects induced voltage occurring in the ink receiving area 52 at the time when charged ink droplets are sequentially discharged from the first area 52a to the second area 52b from nozzles 23 forming a nozzle array 43 designed so as to line up in parallel with the border line on the print head 24 and get a grip on whether or not ink droplets arrive at areas where they are designed to practically arrive on the basis of detected induced voltage. The equipment performs the same operation for the nozzles 23 forming lines of nozzles. Thus, the equipment gets a grip on the dislocation of the nozzles 23 by directly detecting ink droplets.
