The hook is located just above the power supply once the back cover is off. Also there is a drum release centered under the drum that a screwdriver can disengage.

I had this problem too: just unlock the hook under the drum; disengage the drum then pull out the drum; then check the home position if not in position open the behind cover, pull the belt until you get the puller to the home position. You will get the same problem if you will not put the main drum puller to the home position. chimuntu@yahoo.com

T2 indicates an elevator motor failure. Take off the back cover and check the lower limit sensor for the paper tray to make sure its not full of dust.
Reset can be done by holding the reset key down during power up.
Test mode is entered by holding down LINE/PHOTO and the M/P buttons during power up.
Test mode# 102 tests operation of the elevator motor.

Means a clamp error. Inspect the clamp on the drum to make sure it moves smoothly and that that clamping mechanism in the back of the machine works as well.
