A laser printer is producing vertical stripes about half way down each page at about a half inch wide and getting wider with each subsequent print. What is the most likely cause and solution?
  1. The corona wire is faulty and needs to be replaced.
  2. The toner cartridge is broken and needs to be replaced.
  3. The printer drum is faulty and needs to be replaced.
  4. The printer is running low on toner, which needs to be replaced.
Explanation
Answer: C - A faulty printer drum can deposit toner on pages in bands where the laser is not “striking” the paper.
Key Takeaway: The printer drum is responsible for transferring the toner onto the paper where the laser strikes the drum. When a drum is faulty it can deposit toner on the paper incorrectly. The drum will need to be replaced.
