Print quality

Colors are wrong or missing

Prints have a color cast, a missing color or don’t match the screen. Find out whether it’s a clogged ink, a setting or color management, and fix it in order.

  • Time needed: 15–40 min
  • Difficulty: Moderate
  • Checked

You’ll need: Plain paper · A color photo or test page to compare

Try this first

Print a nozzle check from the printer’s maintenance menu and look at each color block. A block with gaps or no ink at all is your answer, so run one cleaning cycle and check again. If every block is complete, the hardware is fine and the cause is in the print settings, starting with grayscale and paper type.

What you’ll notice

  • Blue skies print purple, or greens look yellowish
  • Reds come out orange or pink
  • Everything prints in black and white even with color selected
  • Prints look much darker or duller than the screen
  • A whole page has a green, magenta or yellow tint

Usually caused by

  • Most commonOne ink color is clogged, low or empty
  • Most commonThe job is set to grayscale or black and white
  • SometimesThe paper type doesn’t match the paper loaded
  • SometimesColor is being adjusted twice, by the app and the printer
  • SometimesA bright screen makes prints look dark by comparison
  • Less commonWrong ink in a tank, or a color laser needs calibrating

Step by step

Work down the list in order. Tick off each step as you go: your progress is saved on this device.

On the printer itself

0 of 6 tried

  1. Print a nozzle check and read each color

    From the maintenance or tools menu, print a nozzle check. Compare each color block with the example shown on the printer’s screen or in the manual.

    You should see: A complete pattern in every color rules out clogs; a broken or empty block tells you which color is failing.

  2. Match the symptom to the missing color

    Printers mix most colors from cyan, magenta and yellow. Missing cyan turns blues purple and greens yellow. Missing magenta turns reds orange or yellow and blues a pale cyan. Missing yellow turns greens bluish and reds pinkish. That tells you which ink to look at even before you print a nozzle check.

  3. Clean the head for the failing color

    Run one cleaning cycle, then another nozzle check. Some printers let you clean only the color group or only the black, which saves ink. After two or three cycles, let the printer rest for a few hours before trying again.

    You should see: The failing color block should fill in a little more with each check.

  4. Replace a low or empty cartridge

    If one color is empty or shows a warning, replace it. On printers with a tri-color cartridge, all three colors share one cartridge and one built-in head, so one empty color means replacing the whole cartridge, and the fresh head also clears any clog.

  5. Check the tanks on an ink tank printer

    Look at each tank under good light. If a color looks muddy or the wrong shade, ink may have gone into the wrong tank. Stop printing straight away rather than running cleaning cycles, which pull the mixed ink further into the head.

  6. Calibrate a color laser

    Color lasers use four toners and can drift out of balance or out of register. Look in the setup or maintenance menu for a color calibration or color registration option and run it, then check the supplies status page for any cartridge, drum or imaging unit near the end of its life.

    You should see: Colored text should sit sharply without colored fringes, and gray areas should look neutral.

Common questions

Why do my prints look darker than the screen?

A screen gives off light while paper only reflects it, and most screens are set far brighter than a print can look. Lowering screen brightness gives a fairer comparison.

Why is my printer only printing in black and white?

Usually a grayscale setting in the driver or the app, or an empty color cartridge the printer is working around. Check both settings and print a nozzle check.

Can one empty color stop the printer entirely?

On many printers, yes: they refuse to print until every cartridge has ink, even for black-only pages. Some allow black-only printing for a while; your manual says which.
