6.12.1. Pick up & Registration & Manual paper sensor
This sensor detects whether a recording paper is picked up or not.
When there is a recording paper at the position of the sensor, the input signal of IC300-AF20pin becomes high level.
When there is no recording paper at the position of the sensor, the input signal of IC300-AF20pin becomes low level.
When there is a recording paper at the position of the sensor, the input signal of IC300-AF20pin becomes high level.
When there is no recording paper at the position of the sensor, the input signal of IC300-AF20pin becomes low level.
6.12.2. Print timing sensor
This sensor detects whether a recording paper is at the printing position.
When there is a recording paper at the position of the sensor, the input signal of IC300-W26pin becomes high level.
When there is no recording paper at the position of the sensor, the input signal of IC300-W26pin becomes low level.
When there is a recording paper at the position of the sensor, the input signal of IC300-W26pin becomes high level.
When there is no recording paper at the position of the sensor, the input signal of IC300-W26pin becomes low level.
