Jam detection
This printer is provided with the following paper detection sensors to detect the presence of paper
and whether or not the paper feed is operating normally.
●
Registration paper sensor (SR1)
●
Pre-fuser paper sensor (SR5)
●
Fuser delivery paper sensor (SR4)
The CPU on the DC controller determines a paper jam by checking whether or not paper is present
at the sensor at the check timing. The check timing is stored in the memory of the CPU. If the CPU
determines a jam, it stops the print operation and notifies the formatter of a jam occurrence.
