X: − = left, + = right. Y: − = up, + = down. 0.5 mm per click. X 0 / Y 0 = centred. Push the roll firmly against the edge guide the same way every time; fine-tune with the arrows. The label outline in the preview stays put so you can see the shift.
Normal: “paper size or type or path miss match” a few seconds in (the panel says 4×6), and “paper jam” at the end (the strip is still on the roll) – cut the strip. Pause stops a few cm later (the printer finishes what it already has); don’t pause for long or the printer may give up on the job. Cancel closes the job.
