Pickup, feed, and delivery system
The pickup-and-feed system consists of various rollers that the printer motors drive. The MFP uses
tray 1 (the manual feeding tray) and a cassette in tray 2 as media sources. The printed media is
delivered to the output device that is installed. The output device can be the standard output bin, the
3-bin mailbox, or the stapler/stacker. Only one output device can be installed. Three additional 500-
sheet feeders can be added to the MFP. These input and output accessories are discussed later in
this chapter.
The MFP has a built-in reversing unit that can deliver the pages either face-up or face-down. Face-
down output, which is the default, is the fastest method, and pages are stacked in the correct order.
Face-up output uses the straightest paper path, but pages are stacked in the reverse order.
The tray 1 paper sensor (on the tray 1 pickup assembly; PS105) detects media in tray 1. The tray 2
paper sensor (PS101) detects media in tray 2. The paper-stack-surface sensor (PS107) and the
paper-size-detection switch (SW102) detect the media that is loaded in the tray 2 cassette.
The pickup operation uses three motors (M101, M102, and M103), a clutch (CL101), and two
solenoids (SL101 and SL102). The delivery operation uses five motors (M101, M102, M104, M105,
and M106) and two solenoids (SL105 and SL106) for the delivery sequence. For the locations of
these components, see
Figure 4-13 Motor, clutch, and solenoid locations on page 136.
Six photosensors (PS102, PS103, PS108, PS109, PS110, and PS111) detect media arriving and
passing along the paper path. For the locations of these sensors, see
Figure 4-14 Sensor and switch
locations on page 137. If the media does not reach or pass these sensors within a specific amount of
time, the microprocessor on the DC controller PCA halts the MFP functions and a jam error message
appears on the control-panel display.
