Remove the stapler/stacker feed assembly and perform the following tasks. ● Remove any media from SR2100. ● Check the operation of the sensor flag and sensor-flag spring and make sure that the flag does not block the sensor. If the flag or the spring is damaged, replace the stapler/stacker feed assembly. ● Clean SR2100 by blowing air gently into the sensing area. Check the sensor for correct mounting, cable connection, and alignment with the sensor flag. If the sensor is damaged or nor working, replace the sensor. ● Check operation of the drive gears and belts at the rear of the stapler/ stacker feed assembly.
