printer alignment test
Printer Alignment Test - Check Scale, Rotation & Offset
The geometry section uses known physical references, while the paper edge acts as the external frame.
Fast path: print the standardized sheet, photograph the complete page, and let the browser measure the known test zones.
Paper frame vs pattern frame
Camera perspective must not be confused with printer geometry. The photo is mapped using the paper edges, then the printed fiducials are measured relative to that paper frame.
Fit to Page detection
Uniform scaling around roughly 94-98% is often caused by a print-dialog scaling option rather than a printer fault. Printer Vitals warns you to reprint at Actual Size before making a diagnosis.
What it does not prove
A measured content offset does not by itself prove a mechanical alignment failure. It is an observation that should be combined with the printer settings and a retest.
How to run the test
- Print the official sheet at 100% / Actual Size, Color, Plain Paper, Normal quality.
- Place the full sheet on a dark surface in even light.
- Take a sharp photo with all four paper edges visible.
- Upload it to the browser analyzer.
- Make one conservative change, then retest using the same settings.
Scope: Printer Vitals is optimized for color inkjet output. Results are measurements plus probable causes, not a guarantee of the exact failed component.
