Q1:

Which part of the laser printer should NOT be exposed to sunlight?

A Transfer corona assembly

B PC drum

C Primary corona wire

D Toner cartridge

E None of the above

ANS:B - PC drum

A laser printer is somewhat delicate and, once damaged, often impossible to repair. The drum, in particular, is a critical component: it must not be left exposed to ambient light for more than a few hours, as light is what causes it to lose its charge and will eventually wear it out.
