- 3Use of non-original paper with slightly different dimensions.
- 4Size detection sensor obstructed by paper debris.
Solutions
Diagnóstico rápido
If you see the err-paper-size warning, check if the physical cassette matches the size shown on the display. Often, the error arises from using a card-type paper with settings configured for postcard format.Solución paso a paso
- Remove the cassette and verify the paper is compatible with the tray.
- Access the 'Settings' menu on the printer's LCD.
- Select 'Paper Size' and adjust it to match the actual consumable.
- Ensure no residual paper is trapped in the exit slot.
