GREUS 5 Pack Thermal Printer Cleaning Pen Universal Print Head Cleaning Pen Maintenance Cleaning Kit Printhead Cleaner Dust Stain Remover Pen for Card & Heat Transfer & Electronic Waybill Printer

A couple of swipes back-and-forth on the printer head of my Rollo and it worked like a charm highly recommended

I use one of these about every 100 labels to clean any residue of the element. It definitely helps ensure you get a nice clean thermal print, and I know when I've neglected cleaning it as my thermal prints to get random missing or low visibility areas. It takes all of a few seconds to pop the top, wipe the element a couple times back and forth, and close the printer. So it really comes down to laziness to not do it on a consistent basis as preventative maintenance. 5 pack will last most people a lifetime if only a single thermal printer really, as the only risk is drying out if you leave the cap off. The cleaning fluid is barely left behind on the surface so "running out" takes a lonnng time.

I used to always keep paper towels and rubbing alcohol near my thermal printer. This is much less messy and takes up less space. Easy to use and store.
