The fuser is curling my labels and squeezing out adhesive — why does my label stock distort or jam in the fuser?
Posted by the SuperPrinters team · 7/26/2026
Labels curl, cockle, or shrink after the fuser, adhesive oozes at the edges or die cuts, and the liner may delaminate or the label tunnel/lift. In bad cases the stock wraps and jams in the fuser, leaving melted material or adhesive residue on the fuser roller. Most often caused by heat-sensitive face, adhesive, or liner not rated for fuser temperature (~180-220°c) — typically an inkjet-grade or general-purpose stock run on a toner press, among other possible causes — a full step-by-step diagnostic and fix follows below.
