Checking the high-voltage connector assembly
The assembly uses three spring-loaded pins to contact the toner
cartridge: charging (callout 1), drum ground (callout 2), and
developing roller (callout 3). Verify that the pins are not dirty or
corroded and that the spring-loading action is functional. If the pins
are dirty, clean them using alcohol only. If they are damaged, replace
the high voltage connector assembly.

Paper curl
Paper curl is inherent to the laser printing processes, and occurs
when paper is subjected to heat. Paper curl tends to relax as the
paper cools while resting on a flat surface. The specification for
maximum paper curl when the paper is lying flat before print is 0.2
inches (5 mm).
