What is your first action when windows reports that your hard drive is developing bad sectors?
Answer: D
Correct answer: run scandisk with the "thorough" option

Correct answer: Crystal
In a piezoelectric inkjet a voltage deforms a crystal behind each nozzle, and the sudden change of volume ejects a drop. The other family, thermal inkjet, boils a bubble of ink instead; both are drop-on-demand.

In inkjet printers, what is the most common problem with the paper tray?
Answer: B
Correct answer: malfunctioning pick-up rollers
The rollers pick one sheet from the stack, and as their rubber hardens and polishes with age they slip - feeding nothing, or several sheets at once. That is the commonest tray fault in any printer.
