Fuser Temperature And Warm-Up Time
These settings allow adjustment of the fuser to correct problems with
paper curl or melting letterheads.
Paper curl in which the top and bottom of the page curl toward the
printed side (hot paper curl) can be corrected by reducing the fuser
temperature. Reduce the setting from Normal to No Boost; if
necessary, reduce the setting further to Low Temperature. Verify that
the toner is being adequately fused to the paper at the new
temperature setting.
Paper curl in which the edges of the paper curl toward the printed
side (cold paper curl) can corrected by increasing the fuser warm-up
time. Use the lowest setting that corrects the problem. Setting “0” is
the factory default and is the shortest warm-up time. Setting “5”
increases warm-up time by 90 seconds; lower settings increase the
time proportionately less. Settings other than “0” may reduce
throughput. Use the + or - key to change the number and then select
save.
Melting letterheads may be prevented by reducing the fuser
temperature as described above for paper curl.
