Pickup, feed, and delivery system

Page 55 highlights

Pickup, feed, and delivery system The pickup, feed, and delivery system consists of various rollers that the product motors drive. The product uses Tray 1 (the manual feeding tray) and a cassette in Tray 2 as media sources. The printed media is delivered to either the rear output bin (straight-through printing) or the top output bin (the default destination). A number of 1x500-sheet feeders and one 1,500-sheet paper deck can be added to certain models. These accessories are discussed later in this chapter. 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-size switch (SW102) detects the media size that is loaded in Tray 2. Two motors, a clutch, and a solenoid that are controlled by the DC controller PCA drive all of the rollers in the product. The pre-feed, top-of-page, and fuser-assembly delivery sensors (PS102, PS103, PS700) detect media arriving and passing along the paper path. 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 product functions and a jam error message appears on the control-panel display.

Pickup, feed, and delivery system
The pickup, feed, and delivery system consists of various rollers that the product motors drive. The
product uses Tray 1 (the manual feeding tray) and a cassette in Tray 2 as media sources. The printed
media is delivered to either the rear output bin (straight-through printing) or the top output bin (the
default destination). A number of 1x500-sheet feeders and one 1,500-sheet paper deck can be added
to certain models. These accessories are discussed later in this chapter. 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-size switch (SW102) detects the media size that is loaded in Tray 2.
Two motors, a clutch, and a solenoid that are controlled by the DC controller PCA drive all of the rollers
in the product.
The pre-feed, top-of-page, and fuser-assembly delivery sensors (PS102, PS103, PS700) detect media
arriving and passing along the paper path. 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 product functions and a
jam error message appears on the control-panel display.
