A librarian is complaining about the following printer issue: The printer control panel displays no image. What are two possible causes of this issue? (Choose two.)

  • The contrast of the screen may be set too low.
  • The printer is not turned on.
  • The room temperature is above normal.
  • The print queue is overloaded.
  • The printer lid has not been closed securely.
Explanation & Hint:

When a librarian is facing an issue where the printer control panel displays no image, two possible causes could be:

  1. The Contrast of the Screen May Be Set Too Low: If the contrast setting on the printer’s control panel is too low, it might make the display appear blank or very faint. Adjusting the contrast settings to increase visibility can resolve this issue if the display is otherwise functioning properly.
  2. The Printer is Not Turned On: This may seem basic, but it’s a common oversight. If the printer is not properly powered on, the control panel will not display any image. Ensuring that the printer is connected to a power source and turned on is a fundamental step to resolve this issue.

The other options, such as the room temperature being above normal, the print queue being overloaded, or the printer lid not being closed securely, are less likely to cause an issue with the printer control panel display. Room temperature typically affects the printer’s internal mechanics rather than its electronic display. An overloaded print queue might delay printing or cause operational errors, but it wouldn’t impact the display on the control panel. Similarly, an unsecured printer lid might trigger an error message or halt printer operations, but it’s unlikely to affect the control panel display directly.
