Setup, Compatibility & Care
To install, open the top cover of your Brother QL printer and slide the Alpa-Cartridge DK11221 unit into the designated slot until it clicks into place. Ensure the paper feed is aligned correctly with the printer's internal sensor. For care, keep the cartridges in a cool, dry place and avoid exposing the finished labels to direct sunlight or high-temperature environments, as the thermal reactive coating may darken over time. To clean the printer, use a lint-free cloth or a thermal print head cleaning pen to prevent dust accumulation.
