HP2-B101 · Question #4

Which statements accurately describe how an HP scanner works? (Select two.)

The correct answer is B. The reflected digital image is directly transferred to the CCD. C. The reflection of the original is bounced off mirrors on its way to the lens and the sensor. Options B and C are correct because they accurately describe the optical path inside a flatbed scanner: light illuminates the document on the glass, the reflected light travels through a series of mirrors (C), which redirect it through a lens and onto the CCD sensor, where it…

Which statements accurately describe how an HP scanner works? (Select two.)

  • AThe scanner captures every image in CMYK

Explanation

Options B and C are correct because they accurately describe the optical path inside a flatbed scanner: light illuminates the document on the glass, the reflected light travels through a series of mirrors (C), which redirect it through a lens and onto the CCD sensor, where it is received and converted into digital data (B). These two steps form the core of how the scanner's optical assembly works.

Why the distractors are wrong:

  • A is incorrect because scanners capture images in RGB (Red, Green, Blue), not CMYK. CMYK is the color model used by printers, not capture devices.
  • D is incomplete as written (the answer is cut off), and while placing the image face down is accurate, it describes only the setup step - not a functional mechanism of the scanner.

Memory tip: Think "Mirrors to Lens to CCD" as the light's journey inside the scanner, and remember the RGB/CMYK split with "Scan = RGB, Print = CMYK" - this rule alone eliminates option A on any similar question.
