Introduction:

This application note explains how to adjust the sensor sensitivity of the TSP700II and TSP800II printers. The sensitivity of the sensor is calibrated at the factory, so sensor adjustment is not necessary under ordinary conditions. However, you may need to make adjustments when using non-recommended paper or when the surrounding environment prevents the sensor from working properly.
