Paper registration
As the media trips the Registration Sensor, it briefly stops at the Registration Rollers. Here, the leading edge is
adjusted so it is parallel with the image on the Transfer Belt and synchronized with the Belt’s rotation. Next, the
paper feed motor triggers the Registration Clutch to rotate the Registration Rollers to feed the paper toward the
Transfer Belt and 2nd Transfer Roller.
Transfer belt
The media passes between the Transfer Belt surface and 2nd Transfer Roller. Here, the image transfers to the
page and continues upward toward the Fuser Rollers.
Fuser
The media passes the Fuser Entry Detection Sensor and enters the Fuser. Here, heat and pressure are applied
to the page to bond the image permanently to the media. The toner is impregnated with wax, so it releases from
the fuser rolls without the need of a wiper or oil coating roller. The Fuser Rollers continue to feed the paper
upward to the Fuser Exit Sensor and Fuser Exit Rolls.
Paper exit
If the sheet is single-sided, the paper passes the fuser exit sensor and is fed into the standard bin by the exit
rolls.
