6) Paper Load Detect Sensor: Detects paper in the tray
MPT Drive
MPT can load 50 sheets of plain paper, and when MPT is opened to load papers, the base
plate goes down by cam and isolates with pickup roller for easy paper loading.
When loading papers, pull the extension out all the way and load papers less than 50
sheets on the tray and adjust side fences to not to have papers move around.
When feed signal is sent, solenoid gets operated to disable segment gear and delivers
power from main motor to MPT’s pickup roller. Therefore, when the cam that operates with
MPT’s pickup roller rotation rotates, the base plate rises by base plate spring to generate
feeding force by contacting loaded paper with pickup roller and allows loaded paper to be
fed in orders from top by pickup roller’s rotation.
When the pickup roller rotates once, the segment gear works with solenoid to isolate power
from main motor and the pickup roller stops its rotation to lower MPT base plate to initial
position.
The friction pad isolation method is used for paper isolation method and papers get isolated
one by one with friction pad’s resistance force and friction pad spring’s pressure.
Since paper presence detect sensor is installed, so, when all papers in the tray is used,
MPT detects it and stops feeding operation.
