Light image

Light image — Printed image is too faint

Samsung · Laser Printers

What does Light image mean?

The images or text printed on the page appear too faint or weak. This can be caused by low toner, issues with the LSU light, or contamination of electrical contacts.

Common Causes

  • LSU light power is low or not functioning correctly
  • Toner cartridge is low or faulty
  • Contamination of high voltage contacts inside the printer
  • Incorrect bias voltage or transfer roller issue

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Check the toner level using the Smart Panel program on your computer and replace the toner cartridge if it's low.

  2. 2

    Gently shake the toner cartridge to redistribute toner, then try printing.

  3. 3

    Ensure the printer settings do not have a 'toner save' mode enabled, which can make prints lighter.

  4. 4

    If accessible, clean any visible contamination around the high voltage contacts with a lint-free cloth.

  5. 5

    Try printing a test page to verify if the issue is consistent across different prints.
