The common problem with these printers is that the fuser drum gets scratched
by the heat sensors of the fuser assembly which gets dirty with toner. Take
a look at the drum of the fuser if the protective coating was scratched to
the metal. If this is the case then the fuser needs to be replaced (around
$80.00 for refurbished). If the protective coating is not scratched to the
metal then the fuser can be removed and disassembled to clean the heat
sensors. Use alcohol and Q-tips to clean.
