The network-attached B&W laser printer started printing poorly over the weekend:



I tried printing the printer’s in-built Cleaning Page, twice, and it made no difference.

The printer reports that its black toner cartridge is about 45% full.

Things we could try next, sourced from a quick browse of the web:

  • "Ensure that the toner collection unit isn’t full."
  • "Shake the toner."
  • "Pull out the toner and look at the drums. You can have a waste toner collector gummed up."
  • "If cartridges are low or very low, for better print quality replace the cartridge."
