The Entrust Sigma 524405 Cleaning Cards are the kind of consumable that quietly earns its place in your printer maintenance routine. Each card uses a double-sided adhesive coating to lift debris from card track and transport rollers — the accumulated dust and residue that gradually degrades print quality if left unchecked. The manufacturer recommends using one card with every ribbon replacement, making the habit easy to build in.

The payoff is straightforward: cleaner rollers mean more consistent card output, fewer reprints, and a printer that stays in good working order for longer. This pack of 10 double-sided isopropanol cleaning cards will see you through a reasonable stretch of regular maintenance. Shelf life of up to one year when stored correctly, so there's no rush to use them all at once.

Compatible with Entrust Sigma series printers. Manufacturer part number: 524405-001.
