Five faults account for most of the labeling problems we get called on. Here is what actually causes each one and which component to check first, before you order parts or shut the line down.
If your labeler is flagging, dropping labels, applying them crooked, double-feeding from the magazine or stringing glue, the cause is nearly always a worn transfer or container handling component rather than the machine itself. This guide walks the five faults symptom by symptom, in the order a field tech would check them. If you already know the part you need, go straight to replacement parts or call us.
Flagging is almost always a glue film or a wipe-down problem, not a label problem, even though the label is what everyone looks at first. For the full breakdown by system, see our guide to label flagging causes and fixes.
A label that never makes it to the container is a hand-off failure somewhere between the magazine and the bottle.
Skew is a timing and centering issue. If placement drifts rather than being consistently wrong, look at wear. If it is consistently wrong by the same amount, look at timing.
Feed problems start at the magazine and are frequently caused by a change nobody logged.
Buildup is a symptom of temperature, cleaning cadence or a worn transfer surface. Left alone it turns into every other fault on this page.
Cold glue faults concentrate in the mechanical hand-off. Pallets, grippers, magazine fingers and the glue roller do the work, and they all wear. When a cold glue machine starts misbehaving, the answer is usually a worn surface somewhere in that chain.
Hot melt faults concentrate in vacuum, cutting and temperature. Vacuum and cutting drums, glue pots and heating elements are where problems start. A hot melt machine that suddenly gets worse across every container size is usually a thermal or vacuum issue, not a wear issue.
These four answers get you to the right part faster than a photo of the bad label. Have them ready when you call.
That last one matters more than people expect. A fault that appeared the same week you changed adhesive suppliers or bottle profiles usually is not a worn part at all. If you would rather have someone walk the machine with you, we do on-site Krones labeling machine service and consultations.
Tell us the symptom and the model. We will tell you which component to pull, and whether it is a stock part, a rebuild, or an exchange unit that ships today.

See our labeler preventive maintenance guide — inspection cadence, wear items by machine type, what to keep on the spare parts shelf, and when a rebuild beats running to failure. If the line is already stopped, start with our repair triage playbook.
When troubleshooting points to a worn component, our Krones labeling machine replacement parts page lists what you need by model.
