There is provided a control unit capable of rapid and precise stoppage of an object to be driven by a motor for use in a printer. The control unit has a speed control part to control the object by acceleration control, constant speed control, deceleration control, and stoppage control by controlling a current to be applied to the motor, and also an inertia calculating part(93) to calculate inertia of the object based on angular acceleration of the motor under the acceleration control of the object, and current values to be applied to the motor under the acceleration control and the constant speed control of the object. The speed control part uses the calculated inertia for controlling the current to be applied to the motor.

A printing apparatus arranged to perform printing while a monochrome printing head and a color printing head are moved in a direction in which the two heads are moved, the printing apparatus being arranged to print a plurality of patterns in which the relative quantity of deviation of printing timings of the two heads is changed in a stepped manner to cause a user to select a pattern having the smallest quantity of deviation among the plural patterns. Then, the selected pattern is used as a central value when a plurality of patterns in which the relative quantity of deviation of the printing timings of the two heads is changed in a stepped manner are furthermore printed to cause the user to select a pattern having a smallest quantity of deviation from the plural patterns. The above-mentioned process is repeated as necessary. As a result, the operation which is performed by the user to adjust the printing position can simply and easily be performed. Control is performed in such a manner as to change color to be printed by the color printing head whenever an adjustment mode in which the relative quantity of deviation of the printing timing is adjusted is started.

摘要:
Not only two plates mounted so as to be displaceable in a scanning direction as well as in a sheet forward direction with reference pins as pivots can be adjusted independently by angle adjusting'levers that can be operated by turning, but also a color recording head can be adjusted in the sheet forward direction by a nozzle position adjusting lever with a black recording head as a reference, the nozzle position adjusting lever being disposed on a side wall of a carriage so as to be operable by turning.
