| What you see | Likely cause | Fix |
|---|---|---|
| One color missing or faint | Clogged nozzles or an empty cartridge or tank | Nozzle check, 1 to 2 cleaning cycles, then replace or refill that color |
| Thin white lines through blocks (banding) | Partly clogged print head | Head cleaning, then print head alignment |
| Whole page tinted or wrong colors | Wrong paper-type setting, one low color, or non-matching ink | Match the paper setting, check ink levels, calibrate |
| Blurry edges or colors bleeding | Misaligned print head or very absorbent paper | Run alignment, use better paper |
| Gradients show visible steps | Draft or economy quality mode | Print at Normal or Best quality |

Open this page and the print dialog appears. Choose your printer, color (not grayscale), plain paper and Normal quality, then print. Windows can also print its own basic test page from Settings, Printers and scanners, your printer, Printer properties, Print Test Page.
Most often one color is clogged or low, which shifts every mixed color. Print the nozzle check to see which color has gaps, clean the head, and check that the paper type in the print dialog matches the paper you loaded.
CMYK blocks test each ink directly: cyan, magenta, yellow and black. RGB blocks and gradients test how the printer mixes those inks to reproduce screen colors, which is where calibration and paper problems show up.
