Principles of Operation
Compile Tray
The Compile Tray assembles sets and aligns the paper edges for stapling. When media is fed
onto the Compile Tray, a tamping operation is performed to align the media edge along the
media’s width. The Compile Tray also offsets stapled sets when ejecting to the Stacker Tray.
Figure 2 Compile Tray
Media capacity depends on whether the media is being stapled or not, as well as media size. If
the number of sheets of one stapled set exceeds the Compile Tray limit set in NVRAM, the
sheets exceeding this setting are ejected to the Stacker Tray. This avoids damage to the Staple
assembly. The default capacity value is 50 sheets.
When two or more paper sizes are used and their widths are identical, all sheets are compiled
and stapled as a set, then ejected to the Stacker Tray. If different widths of media are used, sta-
pling is stopped and the paper is ejected to the Stacker Tray.
Tamping
Tamping aligns the media edges using the Left or Right Tamper by moving them to the edge of
paper by their respective motors. Tamping occurs each time a sheet of media reaches the
Compiler Tray. Additional tamping occurs after tamping the last sheet of a set.
Offset
Offset shifts the paper position as each set is ejected to the Stacker Tray to avoid ejection jams
due to the stacking of multiple stapled sets. Offset occurs for these staple positions.
Offset is not executed for small paper.
Compile Tray Sensors / Motors
• Left Tamper Home Sensor
A photo-interrupter to detect the left tamper home position. When the left tamper comes to
the home position, it enters the sensor’s sensing area, which turns the Left Tamper Home
Sensor signal High.
• Right Tamper Home Sensor
A photo-interrupter to detect the right tamper home position. When the right tamper
comes to the home position, it enters the sensor’s sensing area, which turns the Right
Tamper Home Sensor signal High.
• Left Tamper Motor
A DC motor to move the left tamper.
• Right Tamper Motor
A DC motor to move the right tamper.
Eject Assembly
The eject assembly collects bundles from the Compile Tray and is retracted into the Finisher
chassis by the eject motor. This action releases media into the Stacker Tray. Eject assembly
position is monitored by the eject home position sensor.
Stapler
The Stapler staples a set of edge-aligned media. After the Stapler staples the media bundle,
the exit roller rotates together with the paddles to deliver the stack to the Stacker Tray. The Sta-
pler is replaced as a single FRU.
Stapling is completed by actuating the staple motor. When staple supply is low, the low staple
sensor detects it and stapling stops. An error message is displayed to notify the operator. A
similar message also appears when the Staple Cartridge isn’t installed in the Stapler.
