This printer is provided the following paper detection sensors to detect the presence of the paper and weather the paper feed is operated normally or not.
1: Top of page sensor (PS912)
2: Delivery sensor/Reversing sensor (PS915)
The CPU determines a paper jam by checking whether the paper is present at the sensor or not at the checking timing. The check timing is stored in the memory of
the CPU.
If the CPU determines the jam, it stops the print operation and notifies it to the video controller.
