Title:
補正値算出方法及びプリンタ製造方法
Document Type and Number:
Japanese Patent JP4543939
Kind Code:
B2
Abstract:
A correction value calculating method includes: preparing a printer including a motor, a PID control system for controlling the motor, and a memory for storing a correction value, the printer being configured to calculate a value of a current flowing through the motor based on the correction value and an output value of an integral element of the PID control system; obtaining in advance a relationship, for when a property of a motor fluctuates, between a correction value and a sum of an output value of the integral element when a motor is driven at a first velocity and an output value of the integral element when the motor is driven at a second velocity; driving the motor of the printer at the first velocity and measuring an output value of the integral element at that velocity; driving the motor of the printer at the second velocity and measuring an output value of the integral element at that velocity; and determining the correction value to be stored in the memory based on the relationship and a sum of the two measured output values.
