1.3 Media Feeders and Paper Paths
From the fixing unit, the paper is directed to the faceup stack or around the
bend to the delivery rollers
. The delivery rollers push the paper into the
facedown stack.
1.3.2 Optional Cassette Paper Path
The optional cassette feeder mounts underneath the printer and holds the
drawer-style cassette. The cassette holds up to 250 sheets of paper or 20
envelopes. The paper size and cassette type are fixed and cannot be altered.
Figure 1–6 shows the paper path when feeding from the cassette. When a
print command is received and the cassette is selected, the DC control board
starts the feed sequence. The cassette pickup roller
turns, pushing the top
sheet of paper into the cassette feed rollers
. The cassette feed rollers push
the sheet up into the feed rollers
in the printer.

The feed and the stationary pickup rollers
direct the sheet into the paper
path, as shown in Figure 1–5.
1.3.3 Cassette Size Sensing
When a cassette is installed, its molded keys engage the size-sensing switch
in the feeder. The DC control board reads the size-sensing switches and sets
the image size to correspond. The size-sensing switches are designated SW901,
SW902, and SW903, as shown in Table 1–5 and Figure 1–7.
