"Worksheet","Use a printer’s internal page to separate device and computer faults","Evidence status","Your configuration"
"Purpose","Compare an internal printer page with a simple computer print. The two checks travel through different parts of the workflow and can narrow where the fault begins.","Proposed workflow",""
"Check","Question to record","Decision","Your observation"
"Internal page works; computer fails","Queue, connection or software remains a candidate","Inspect the computer route",""
"Both fail similarly","Device, media or supplies remain candidates","Follow model troubleshooting",""
"Simple document works; one file fails","Document or application remains a candidate","Investigate that file",""
"Example","In a hypothetical case, the printer produces its internal report but a laptop job remains pending. Replacing ink would not address the observed queue failure. If another simple file from that same laptop succeeds, the investigation narrows again to the first document or its application settings.","Illustrative; not a measured product result",""
