PURPOSE How to choose which printer is used by default. GENERAL STEPS Open printer, scanner, device, or print queue settings and select the printer or scanner related to the task. VERIFY RESULTS Print or scan a test page when appropriate and confirm the output is readable, complete, and sent to the correct destination. TROUBLESHOOTING If printing or scanning fails, check power, network connection, paper, toner or ink, device status, stuck jobs, and error messages on the device display. BEST PRACTICE Do not force paper trays, covers, cartridges, or jammed pages. If something resists, stop before a simple paper jam becomes a hardware repair ticket.
