PRINT / COMPARE / TROUBLESHOOT
Faded or light prints
Engineering preview: usable draft patterns, not a physically validated release. See validation limits.
Check economy mode, paper type and supply messages before assuming an empty cartridge or a clogged nozzle. Use the right path for ink and toner.
No authenticated fault photographs or physical repair validation have been provided. These are cautious checks, not a confirmed repair diagnosis.

Approved normal/fault photos will appear here after permission and content review. Model, paper and settings must match the photograph.
These are checks to investigate, not a diagnosis or a probability of failure. Model-specific maintenance and physical sample validation are still required.

Identify the printer before maintenance
First check: Look up the model's official manual to establish whether it uses ink cartridges, refillable ink tanks or toner. Do not guess a cleaning procedure.
Look for: Look for distinct gray steps and visible color patches. Pale output can reflect settings, paper or supply; it does not prove an empty cartridge.
Verify: Print / PDF: Black & white. Choose the paper loaded in your printer.
Stop: Stop if the printer reports an error or an unsafe condition. If the allowed procedure does not help, find official model instructions.
Paper, quality or color settings
First check: Compare the loaded paper with the selected paper type, turn off draft/economy mode for the test, and check that color is enabled when needed.

Before you print again
Does requesting a print mean it printed?
No. The browser can request a dialog, but cannot tell whether you cancelled, sent the job or received paper. Check the preview and the physical result.
Why are there two paper sizes?
Each PDF has a native Letter or A4 page box. Choose the same size in the printer dialog, use Actual size / 100%, and disable headers, footers and Fit to page.
Can this sheet diagnose my printer?
It is a comparison aid. A generic sheet cannot identify a failed part, measure ink remaining, certify colors or replace the manufacturer's model-specific checks.
