HP 4 plus C2037A, C2021A, 5n C3952A, 5 C3916A, 5m C3917A, 4 C2001A Printing from the PC Tray Tray

Printing from the PC Tray (Tray 2)

PC tray selection is provided by the Formatter PCA, as configured by the control panel or by software. When the DC Controller PCA receives a PRNT signal, it starts the Scanner Motor (M5) and the Main Motor (M1). When the fusing roller reaches the minimum operating temperature (approximately 183° C), the PC tray (Tray 2) pickup roller clutch solenoid (SL1) is energized for 1 second, allowing the roller to make one rotation. The PC tray pickup roller then feeds a sheet of paper from the PC tray into the PC tray input feed rollers. The PC tray input feed rollers turn until paper reaches the Input/Registration Sensor (PS1). When the media is sensed at (PS1), the pickup motor (M2) stops and the paper is carried through the remainder of the print path by the Main Motor (M1).

The Formatter PCA sends the VDO signal to the print engine after the paper reaches the Input Paper Sensor (PS1). This aligns the leading edge of the toner image on the photosensitive drum with the leading edge of the paper. After the paper passes the drum and the fusing rollers, it triggers the Paper Exit Sensor (PS3). The paper is then fed into the output tray.

If the paper does not reach or clear each sensor within a specified time, the microprocessor on the DC Controller PCA assumes a paper jam occurred and informs the Formatter PCA.
