Zebra, Rollo & Munbyn 4×6 Fanfold Printer Setup

Fanfold labels load differently from roll labels — there's no spindle, and the stack sits behind the printer. Here's the short version for the three printers we get asked about most.

Zebra ZD420 / ZD220

1. Open the top cover and remove any roll holder if fitted.
2. Place the fanfold stack flat behind the printer with the printable (matte) side up.
3. Feed the leading label through the rear fanfold slot.
4. Adjust the media guides so the label is snug but not pinched.
5. Run media calibration: hold the Pause + Cancel buttons until the printer cycles 2–3 labels.

Rollo X1038

1. Place the fanfold stack on a flat surface directly behind the printer.
2. Feed labels through the rear slot, printable side up.
3. Close the lid; press the feed button once — the Rollo auto-calibrates per label.
4. If it skips labels, run a manual calibration from the Rollo app.

Munbyn ITPP941 / 130B

1. Open the top cover and ensure no roll spindle is engaged.
2. Place the fanfold stack behind the printer, label side up.
3. Feed through the rear slot, adjust the side guides.
4. Hold the feed button for ~3 seconds to trigger gap calibration.

Software settings that catch people out

• Set page size to 4 × 6 inches (or 100 × 150mm) — not A6.
• Set print darkness/density to 8–12 for crisp barcodes.
• Disable any 'fit to page' scaling in your shipping software.
• On Windows, set the printer's default paper size — not just in the app dialog.

Once calibrated, Oplect 4×6 fanfold labels should feed and print without further adjustment. If you see double-feeding or skipped labels, run calibration once more with a fresh stack.
