How to use

Store the cartridge in a cool, dry place until installation. Follow your printer manufacturer’s instructions to remove the spent cartridge and install the replacement, ensuring the cartridge locks into the carriage securely. Perform a test print or nozzle check from the printer menu after installation to confirm proper contact and print quality. If necessary, run the printer’s cleaning cycle according to the manual to optimize initial output.

Usage recommendations

For consistent results, use the cartridge in printers that explicitly support LC426XLBK-compatible supplies and avoid prolonged storage after opening. Keep replacement cartridges in their sealed packaging until ready to install and handle the cartridge by its body to prevent contamination of contact points and the printhead. If print quality falls below expectations, follow routine maintenance procedures: run one or two cleaning cycles, realign the printhead if supported, and print a calibration page.
