"Worksheet","USB printing works but scanning fails: check the separate workflow","Evidence status","Your configuration" "Purpose","Printing and scanning use different software paths. Confirm the scanner’s exact connection and supported application rather than treating a successful print as proof that scanning is configured.","Proposed workflow","" "Check","Question to record","Decision","Your observation" "Print queue","Sends a print job","Does not prove scanner setup","" "Scan application","Acquires an image","Needs its own supported route","" "Output file","Saved and reopened result","Confirms the task completed","" "Example","In a hypothetical setup, a generic driver creates a working print queue but the chosen scan application cannot see the device. The next useful check is the model’s supported scanner setup for that OS, not repeated test printing or replacing the ink.","Illustrative; not a measured product result","" "Source","https://support.microsoft.com/en-us/windows/hardware/printer/fix-printer-connection-and-printing-problems-in-windows https://support.apple.com/en-euro/guide/mac-help/mh14002/27/mac/27 https://files.support.epson.com/docid/cpd6/cpd60206/helpcontents.html","Official references; scope in article","" "Result","Accepted / unresolved / needs correction","Record date and configuration",""
