Abstract

PURPOSE: To detect surely whether a print medium exists or not to prevent blind printing by mounting a print medium sensor on a carrier together with the print head.
CONSTITUTION: Print medium sensor 6 is mounted on carrier 5 together with the pring head. This sensor 6 gives output signal a to decision circuit 10. Printer control circuit 11 moves carrier 5 after print completion and issues a print command to print head 3 and gives decision permission signal b to decision circuit 10; and if a print medium presence signal is inputted, circuit 11 executes printing. If a print medium absence signal is inputted, printer control circuit 11 performs the alarm processing and stops printing and sends alarm signal d to alarm circuit 12 and waits intervention of an operator. When the print medium is mounted correctly by the operator, alarm release signal e is sent from operation switch 13 to control circuit 11, and control circuit 11 performs succeeding processings to enter print operations again. In the figure, 2 indicates the position of the print medium sensor.
