Multi-function machines are prone to complex jams and scanner errors, making all-in-one printer repair a frequent necessity for busy workspaces. If your device refuses to copy or scan, start by clearing any hidden paper scraps from the rear duplexer roller. Next, power cycle the unit while it is plugged directly into a wall outlet rather than a surge protector. This simple trick often resets stuck sensors and clears lingering error codes without professional intervention.
