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.
