Printing from the MP Tray (Tray 1)
MP tray selection is provided by the Formatter PCA, as
configured by the operator’s control panel or by a software
application. The MP tray (Tray 1) feed system’s paper motion
begins when the DC Controller PCA, after receiving a
PRNT
signal, starts the Scanner Motor (M5) and the Main Motor (M1).
When the fusing roller reaches the minimum operating
temperature (183° C), the MP pickup roller clutch solenoid (SL2)
is energized for 1 second, allowing the MP pickup roller to make
one rotation. Clutches and solenoids work together to start and
stop gears and rollers used for paper movement. The MP pickup
roller then feeds a sheet of paper from the MP tray (Tray 1).
The Formatter PCA sends the
VDO signal to the print engine
within a specific time period after the paper reaches the
Input/Registration 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 then is directed to 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.
