How to Thread a Label Dispenser? A Step-by-Step Guide

For the full breakdown, see our best Electric Label Dispenser guide.

Whether you run a small business shipping products or manage a warehouse line, a label dispenser saves hours of peeling by hand. The catch? Every model routes the liner differently. A powered dispenser has motor-driven rollers; a manual one has simple slits and a peel edge. Get the path wrong and labels jam, tear, or refuse to separate. This guide walks you through the differences — and the exact sequence for the most common types.

Before You Start: The Two Rules That Prevent Jams

Two mistakes cause nearly every threading problem we see. First, loading the roll while the machine is still on. Second, powering the unit on before the liner is fully threaded.

The Novexx ALS 104 manual is explicit: the main switch must be off before inserting the roll, and the device must not be turned on until the label strip is threaded completely. That’s not a suggestion — powering up mid-thread can pull the web crooked and ruin the roll. On any powered model, find the main switch and flip it off before you touch the roll.

Powered Label Dispensers: The Standard Roller Path

Powered dispensers (like the LD-100 and LD-200-RS) use a motor to advance the liner, so the web must engage every roller correctly. Most follow the same general path — the key difference is which guide comes first.

1. Turn the power switch OFF. Confirm it before loading anything.
2. Place the label roll on the Label Roll Holder with labels facing outwards, then slide the Roll Edge Guide(s) snug against the label width.
3. Remove the first few labels to expose the backing paper — you can’t thread a roll that’s still fully intact.
4. Feed the backing under the first web guide, then between the Stripper Bar and the Guide Rod.
5. Route it under or over the second web guide (check your model’s diagram — the order matters).
6. Secure the liner on the take-up area if your model has one.

The Novexx ALS 104 adds a useful detail: unroll about 1 meter of label strip, remove the labels, and pass the backing paper around the first deflection roller, through the sensor slot, under the pressure roller to the dispensing plate, then around the plate to the second deflection roller. If your powered unit has a sensor slot, the liner must pass through it — that’s how the machine knows where the next label is.

Manual Dispensers: The Simple Slit-and-Peel Route

Manual dispensers are simpler — no motor, no sensors, just a peel plate and a slit or two. The threading pattern is short but still matters.

1. Remove the first label (or two) so the backing has a free end.
2. Place the roll in the dispenser, labels facing outwards.
3. Thread the backing through the slit(s) or guides on the front of the unit, following the model’s groove.
4. Close or lock the dispenser to hold the roll in place.
5. Pull the backing so the next label pops up over the peel edge for dispensing.

The real trick with manual units is tension.

Printer-Mounted Peelers: A Different Beast

Printer-mounted peelers (like the Novexx ALX 73x) work differently — the label web travels through the printer first, then peels at the dispenser edge. Here the routing is dictated by the print engine’s path, not just the dispenser’s rollers. The label strip must enter the print path correctly, the sensor must register the gap between labels, and the liner must exit through the peeler’s specific slot. If you’re threading one of these, consult the printer’s own manual for the web path — it’s the most model-specific of the three types, and guessing wrong can damage the printhead.

The Take-Up Area: Securing the Liner

Many powered models have a take-up reel that winds the used liner. If yours does, this is the final step: pull the liner across to the take-up hub, wrap it once or twice around the hub, and lock the spool. The winding direction matters — follow the arrow on the hub if there is one. If you skip this, the liner piles up at the exit and eventually jams the feed. On manual units without a take-up, just let the liner trail over the edge; you’ll tear it off in strips as you work.

How to Fix Common Label Dispenser Issues

Here are the most common threading problems and what usually causes them:

If you’re still stuck after re-threading with these steps, check your user manual’s diagram — the routing path is highly specific to each model. The same term “label dispenser” covers very different machines, and the single biggest cause of persistent jams is following a path meant for a different type of unit.
