Step 5: Fuse
Once the image has been fully transferred to the media, the transfer roll helps move the paper into the fuser
area.
The fuser (F) applies heat and pressure to the page to melt the tiny toner particles and bond them permanently
to the media. The fuser moves the paper from the rollers and into the exit bin.
Service tips:
•
If the fuser rolls are damaged, they can cause toner to be pulled off the page or cause paper jams.
•
Toner that rubs off a printed page can be a sign of a malfunctioning fuser or an improper media setting.
Always check the paper type setting before replacing the fuser. A common mistake is to print on heavier
media (such as card stock) with the paper type set to plain paper.
•
Never pull media with unfused toner up through the fuser if you can help it; try to back the jammed page
out of the fuser in the opposite direction it was traveling.
