Clean the corona wire

A grey vertical streak or one-sided fade on a laser is often a dirty corona wire. Slide the green tab a few times — it's a 30-second fix.

01 · Identify — does this match what you see?

  • Faint print down one side of the page
  • Grey background streaks vertically
  • Print fades after the printer sat unused

02 · Resolve — follow in order

  1. 1

    Open the front cover and remove the drum-and-toner assembly.

  2. 2

    Find the green tab on the drum unit (top edge). Slide it left to right and back 6–7 times.

  3. 3

    Return the tab firmly to its home (marked) position — a centred tab causes a permanent streak.

  4. 4

    Reinstall the assembly and close the cover.

  5. 5

    Print a test page to confirm the fade/streak is gone.

Pro tip

Make this part of every toner change. One minute of sliding the tab saves a service call and a page of complaint prints.
