What this grayscale test checks
21-step chart
21 evenly spaced blocks from white to black let you spot missing steps caused by low toner or clogged nozzles.
Smooth gradient
A continuous 256-level gradient reveals banding or print-head gaps that the step chart might miss.
Radial gradients
Circular gradients test radial ink distribution and expose uneven pressure across the print zone.
Fine line reproduction
Lines from 0.25pt to 4pt confirm your printer can reproduce very thin marks — important for documents and photos.
Text sharpness
Multiple font sizes from 8pt to 20pt verify text clarity and fuser performance on laser printers.
Parallel line banding check
A series of equally spaced horizontal lines immediately shows drum banding or roller defects.
Frequently Asked Questions
What is a grayscale test page?
A grayscale test page checks how evenly your printer reproduces shades from pure white (0%) to pure black (100%). It includes step charts, gradients, and fine line tests.
Does a grayscale test waste colour ink?
No. Most printers can be set to 'print in black only' or 'grayscale mode' in the print dialog, which uses only the black cartridge or toner.
What does a smooth gradient tell me?
A smooth, banding-free gradient means your black ink or toner is distributing evenly and there are no clogged nozzles or damaged drum areas.
I see horizontal bands — what does that mean?
Banding in grayscale output typically indicates clogged print-head nozzles (inkjet) or a worn drum unit (laser). Run a head-cleaning cycle or replace the drum.
