Fuser Temperature (Fuser Temp)
This adjustment can be used to help solve some customer problems with paper curl on low grade papers and
problems with letterheads on some types of media.
The fuser temperature can be adjusted to: Normal, Lower, Lowest. The default is Normal.

Warm Up Time
You can change the amount of time the printer warms up before allowing pages to print by changing this
setting from 0 to 5. The factory sets the warm up at 0 or no warm up time. This time period lets the backup roll
heat up and helps reduce curl in some environments.
Transfer
The transfer can be adjusted to Low, Medium, or High. The default setting is Medium.
Print Contrast
The print contrast setting controls the developer voltage offset.
The print contrast can be adjusted to Low, Medium, or High. The default setting is Medium.
Charge Roll
The charge roll can be adjusted to Low, Medium, or High. The default setting is Medium.
Gap Adjust
The setting adjusts the minimum gap between sheets. Increasing this value may reduce curl of some printed
media and eliminate some output bin stacking problems. However, increasing this value also results in slower
overall performance, measured in pages per minute. The range of values is 0 to 255, and the default value is 0.
