13-32. A nine-pin dot matrix print head prints in near
letter quality mode by making two passes for
each line, advancing the paper what distance
before the second pass?
1. One-half line
2. One-half letter space
3. One-half dot space
4. One dot space
13-33. A 24-pin print head prints near letter quality
faster and with greater resolution than a 9-pin
print head for which of the following reasons?

13-41. During a laser printer’s print cycle, a charge of
-600V is applied to the print drum by what
device?

2. Laser diode carriage motor
3. Laser beam lens assembly
4. Laser beam shutter
13-43. What effect, if any, does the laser beam striking
the print drum have on the print drum?
1. The area of the print drum becomes
positively charged
2. The area of the print drum becomes
negatively charged
3. Any charge on the print drum becomes
neutralized
4. None
