The second end is opposite the first end and has been formed by cutting off the continuous sheet. In image formation only on the first side, the continuous sheet is cut off at a first position behind the last page image formed on the first side. In image formation on both the first and second sides, the continuous sheet is cut off at a second position behind the first position.

Abstract: A printer (1) has a paper feed roller (11) and a tractor (6) for conveying continuous paper (2) passed a printing position. During printing, the paper feed roller (11) is intermittently rotationally driven at a speed enabling conveying the continuous paper (2) a second feed distance per unit time, and the tractor (6) is held in a state enabling it to be rotated pulled by the continuous paper by means of the paper feed roller (11) while being intermittently rotationally driven synchronously to the paper feed roller (11) at a speed enabling conveying the continuous paper (2) a first feed distance that is less than a second feed distance per unit time (steps ST1, ST2). Each time the continuous paper (2) is conveyed one page length, the paper feed roller (11) is additionally rotated to eliminate a feed distance deficiency due to slipping (steps ST31 to ST33). The printer can therefore convey continuous paper with good precision without applying a great load, and can prevent a drop in print quality.

Abstract: An ink jet head is fed in a main-scan direction to record one line on a recording paper. Thereafter, the recording paper is fed in a sub-scan direction for one line. A corrected feeding amount A is calculated by adding a correction value C1 to a basic feeding amount B.

For example, D=(p?k)/2. R is a random number in a range between 0 and 1. Gradation unevenness and/or black and white streaks caused by periodical feeding unevenness become inconspicuous since the correction value C1 is changed on a random basis.

Abstract: A security system for an unattended printing mechanism, such as that found in an automatic teller machine. The security system has a programmable microprocessor which sends data to a journal printer and actuates a journal motor that controls the rotation of the paper take-up drum. A timing disk is rotationally attached to the take-up drum. A sensor mounted adjacent the timing disk senses the rotation of the timing disk and the rotation of the take-up drum. As the timing disk rotates, the sensor generates alternating high and low signals. The sensor signals are fed to the microprocessor, which assesses the number of high/low signals, and the amount of paper being fed to the take-up roll. When it does not see a proper number of high-to-low transitions for a given amount of journal motor rotation, the microprocessor provides a signal that a jam has occurred in the printing system. The microprocessor continually monitors the sensor signals.
