When counting the actual number of pulses between M and M, the encoder 3S operates between the time when the other mark sensor 6B (B sensor) detects the lower test mark KN and the time when the upper test mark KM is detected. If the actual number of pulses is determined from the interval between the lower test mark KN and the upper edge of the card, the other mark sensor 6B similarly sets the lower test mark KN to the lower test mark KN. The total number of pulses emitted by the encoder 3S during the period from when the error is detected to when the upper edge of the maintenance card SK is detected may be counted.

Steps S1 and S22 are for explaining the processing procedure relating to the pulse interruption processing. First, in step S20, it is determined whether the printing mode is the normal printing mode or the maintenance mode. In the case of the mode, the standard pulse number is decremented by 1 until the printing stage of the day in step S22.

FIG. 6 illustrates a processing procedure for calculating the standard pulse number up to the printing stage of the day to be conveyed. In calculating the pulse number, first in step S23, A correction value N is obtained by dividing the actual number of pulses obtained in step S11 by the standard number of pulses from the card lower edge Kd to the test mark KM.
Next, in step S24, the number of pulses to be conveyed can be calculated by multiplying the correction value N by the standard number of pulses of the time card TM up to the printing stage of the day.

FIG. 7 is a block diagram for explaining the overall configuration of the present invention.
