A client using a Point-of-sale (POS) system complains that their thermal printer is producing a dark and smudged print. Which of the following is a good first troubleshooting step?
  1. Wipe clean the heating element.
  2. Replace the ink cartridge.
  3. Replace the paper.
  4. Replace the spring.
Explanation
Answer: A - A good first troubleshooting step for a dark, smudged print from a thermal printer is to wipe clean the heating element.

Key Takeaway: If the thermal element does not make proper contact with the specially coated paper, the image will come out incorrectly. The most likely culprit of this is that the heating element is dirty. Although there is a spring in thermal printers, replacing it is not a first troubleshooting step
