II. Troubleshooting

❌ Label shrunk / wrong dimension:

• Scale was not set to 100%. Re‑open print dialog and disable “Fit to page”. Double‑check paper size is 4×6 inch.

❌ Blank or partial printed label:

• Verify you are using direct‑thermal 4×6 label rolls. Confirm label roll is loaded with the coated printable side facing the print head.

❌ Y813BT does not show in printer list:

• Re‑install the latest KNAON Y813BT driver, confirm USB / network connection is active.
