Your labels are coming out faded. The black's gone grey, the colour's washed out, and you're about to bin a perfectly good label printer because you think the head is shot.
It probably isn't. It's clogged. This is Brother's genuine CK-1000 print head cleaning cassette, made specifically for 50mm-width label printers. You slot it into the back of the unit, close the cover, and the printer runs its own cleaning cycle automatically. No disassembly, no cotton buds dipped in isopropyl, no guessing.
It's a genuine Brother part, so you're not risking your head with a third-party solvent that could dissolve the coating. One cassette, one clean, labels back to full colour and crisp black text.
If your 50mm Brother label printer is printing soft or streaky, try this before you start hunting for a replacement unit
