Question 1 of 3
A different problem?
These choices cover ten common symptoms. If your problem is different, first identify the printer, check its error display and compare the loaded paper with the print settings. Do not guess a cleaning procedure.
Find support for your exact model
Choose your manufacturer, region and model. Follow toner instructions for laser printers; inkjet nozzle cleaning does not apply.
Safety comes first
Stop printing if there is smoke, unusual smell or overheating, leaking fluid, mechanical damage, or an error that instructs you to stop. Follow the manufacturer's safety instructions and contact official support. Do not dismantle hot or high-voltage parts.
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.
