Feed from Tray 4
At the start of a print cycle the Tray 4 Pick Roller moves a sheet of paper to Tray 4 Feed
Roller. The Feed Roller moves a single sheet of paper out of Tray 4 and toward the Tray 4
Take Away Roller. The Tray 4 Retard Roller ensures only one sheet of paper is fed. Tray
4 Take Away Roller transports the paper to Tray 3 Take Away Roller. As the sheet of
paper is driven toward the Tray 3 Take Away Roller it actuates the Tray 4 Take Away
Sensor, notifying the Print Engine Controller Board logic that the paper has been delivered
to the Tray 3 Take Away Roller, which then drives the sheet to the Tray 2 Take Away
Roller. As the sheet of paper is driven to the Take 2 Take Away Roller it actuates the Tray
3 Take Away Sensor, notifying the Print Engine Controller Board logic that the paper has
arrived. The Tray 2 Take Away Roller drives the sheet to Tray 1 Take Away Rollers. Tray
1 Take Away Roller drives the sheet of paper to the Registration Roller. After that, the
sheet continues along the printer paper path until the sheet of paper, complete with fused
image, is delivered to an output bin.
