Choose color mode
In the print dialog, select Color rather than Grayscale or Black only. Use Normal quality first—not Draft, Eco, or Photo.
Color / CMYK test
Color printer test page
Print one controlled sheet to check cyan, magenta, yellow and black output, reveal banding, and separate an ink problem from a driver or alignment problem.
- CMYK channel blocks
- Blend and gradient checks
- Alignment and small-text targets

Three settings make the test useful.
A scaled or economy-mode print can look like a printer fault. Start with a controlled print before changing ink, toner, or hardware.
Print at actual size
Set scale to 100% or Actual size, match A4 or Letter to the paper in the tray, and turn browser headers and footers off.
Inspect in good light
Let ink settle for a minute. Compare each channel, the blend ramp, the line grid, and fine text before running a cleaning cycle.
Read the result
Every defect leaves a different clue.
What you seeLikely meaningNext move
One CMYK block is missing
That cartridge or nozzle channel is empty, blocked, unseated, or disabled.
Check ink level and seating, then run one nozzle check and one normal cleaning cycle.
Horizontal white bands
Some inkjet nozzles are not firing consistently. On a laser, toner transfer may be uneven.
Run the printer’s nozzle check or cleaning tool; avoid repeating deep cleans back-to-back.
Colors shift but blocks are solid
The printer can output each channel, but the driver, media profile, or paper setting may be wrong.
Reset color settings, choose the correct paper type, and test from another application.
Grid lines look doubled
Color registration or printhead alignment is off.
Run the built-in alignment routine, then print this same sheet again for comparison.
01 / Channels
Start with CMYK, not the photo.
A photograph can hide the source of a color problem because every area mixes several inks. Separate cyan, magenta, yellow and black blocks make a weak channel obvious before the blend ramp tests how those channels work together.
- Solid blocks should be even from edge to edge
- The blend should change smoothly without abrupt stripes
- Black should look neutral—not brown, blue, or washed out
02 / Limits
A browser page is diagnostic, not a color proof.
Your screen emits RGB light while a printer places ink or toner on paper. This sheet can reveal missing channels, banding, registration and obvious balance problems, but it cannot certify Pantone, FOGRA, or press-proof accuracy without a calibrated workflow.
- Paper brightness changes perceived color
- Draft mode can mimic low ink
- Third-party cartridges may use different color formulations
FAQ
Questions before you print.
How do I print a color printer test page?+
Choose Color / CMYK above, match the paper size, click Print test page, select Color and 100% scale in your browser dialog, then print one copy.
Why is one color missing from the test page?+
The matching ink channel may be empty, incorrectly seated, dried, or clogged. Check the cartridge first, then run the printer’s own nozzle check before cleaning.
Does this color test work with laser printers?+
Yes. The color blocks, gradients, grid and text checks work for color laser printers. Nozzle-specific advice applies only to inkjets; laser defects more often involve toner, drums, transfer belts, or fusers.
Should I use RGB or CMYK to test a printer?+
Use both for diagnosis. Separate CMYK blocks reveal the four print channels; blended screen colors show how the driver converts and combines them. Neither replaces a calibrated press proof.
