A worked example

Shown solved, with the whole explanation open: this is what every question here carries.

3-8HardwareModerate

A technician removes the imaging kit from a colour laser and is called away mid job. Where should the kit be left while the printer stands open?

Out of direct light on a flat surfaceCorrect · your answerCorrect. Light exposure and scratches are the two documented risks to the drum.
Under a desk lamp so the drum stays warmDirect light on the drum is exactly what the procedure warns against.
Back in its bay with the door propped openA propped door leaves the bay open to light and to knocks from passers by.
On the printer's output bin for easy reachAn output bin invites contact with the drum surface and offers no shade.

Correct.

Concept

A photoconductor is designed to react to light. Ordinary room lighting keeps working on the drum once the assembly is out of the machine, and the effect shows up later as marks on printed pages.

Why A

Shielding the drum from light and keeping the assembly flat protects the surface that forms the image, which is the pairing the replacement procedure calls for.
