摘要： Disclosed is a printing apparatus that performs printing onto a print medium including a transporting device that transports a print medium, a plurality of printing heads, a photographing unit that photographs the print medium, a shift detecting chart forming device, and a correcting device. The shift detecting chart forming device forms a shift detecting chart having a first line segment group consisting of first line segments that are printed onto the print medium at given intervals in an orthogonal direction with respect to the transportation direction with a reference printing head, and a second line segment group formed along the first line segment group, and consisting of second line segments that are printed with a subsequent printing head. The correcting device corrects a printing timing with the subsequent printing head relative to the reference printing head in accordance with a density variation of the photographed shift detecting chart.

摘要： A transport control method for use in transporting a medium in a predetermined direction by an upstream drive roller and a downstream drive roller, to operate the downstream drive roller by using PID control based on a detection value of a tension sensor disposed downstream of the upstream drive roller and upstream of the downstream drive roller for detecting tension. The transport control method includes a stable state determining step for determining, at time of the operation, whether a difference between the detection value of the tension sensors and a target value is within a stable width to make a stable state which maintains a stability time; and a gain decreasing step for decreasing a gain of the PID control to be less than an initial value when the difference is determined to be in the stable state.

摘要： A rotary encoder correcting method for a transport apparatus having a rotary encoder for outputting output signals in response to rotation of a transport roller. The method includes the steps of setting beforehand the number of n-divided output signals obtained by dividing, by n, the number of output signals outputted from the rotary encoder with one rotation of the transport roller; measuring a divided area shift time for each divided area when a printing medium is transported at constant speed and each time the number of output signals agrees with the number of n-divided output signals; and calculating a correction coefficient for each divided area based on the divided area shift time. The divided area shift time is corrected for each divided area of the rotary encoder based on each correction coefficient when a process is carried out on the printing medium.
