If yes, the left side movement amount of the doctor roller is determined in Step P305 from the left side movement amount of the doctor roller. After the value is calculated and stored in the memory M76, in Step P306, the forward rotation pulse output command corresponding to the absolute value of the movement amount of the left side of the doctor roller is output to the left adjustment stepping motor driver 66a. The process proceeds to step P307.

  Next, if the result is NO in step P304, the absolute value of the left side movement amount of the doctor roller is calculated from the left side movement amount of the doctor roller in step P308 and stored in the memory M76, and then in step P309. A reverse rotation pulse output command corresponding to the absolute value of the movement amount of the left side of the doctor roller is output to the left adjustment stepping motor driver 66a, and the process proceeds to step P307 described above.

  Next, after reading the movement amount of the right side of the doctor roller from the memory M75 in step P307, it is determined in step P310 whether or not the movement amount of the right side of the doctor roller is 0. On the other hand, if NO in step P315, 1 is overwritten in the right-hand side adjustment stepping motor rotation presence / absence storage memory M61a in step P311.
