1. What are the two types of feeder mechanisms used in printers?

   1. □ Continuous tractor feed

   2. □ Continuous form feed

   3. □ Friction feed

   4. □ Injected

2. Which of the following devices use friction feeder mechanisms? (Choose two.)

   1. □ Laser printers

   2. □ Fax machines

   3. □ Dot matrix printers

   4. □ A printer that prints hundreds of payroll checks

3. A positive charge is applied to the paper by which laser printer component?

   1. ^ The laser

   2. ^ The print drum

   3. ^ The registration rollers

   4. ^ The transfer corona wire

4. What is the purpose of the negative charge on the print drum of a laser printer?
