2.1.1.1 Paper Feeding
Paper can be fed into the printer from the paper feed tray (150 sheets) or from the manual feed slot (1 sheet at
a time). Paper fed by the paper take-up roller is transported to the transport roller, pre-image transfer roller,
and then exit roller. After this, the paper is fed out onto the print tray. The starting position of an image is
decided by the paper take-up sensor (PC1). A photo sensor is used as the paper take-up sensor (PC1) and the
paper exit sensor (PC3).
Paper Feeding Tray (Standard Tray)
When the paper take-up solenoid is energized, the main motor (M1) drive is transmitted to the paper take-up
roller via the paper take-up clutch (a one-way clutch) to rotate the paper take-up roller one revolution. At the
same time, the depression cam rotates and releases the paper lift-up plate to feed the top (first) paper. The
fixed separating pad is used for the paper separation system. It prevents the second or later sheets from being
fed together with the top paper.
