Pro Tip
Because the Lexmark 26 tri-colour cartridge features an integrated printhead, every replacement cartridge installs a fresh set of microscopic spray nozzles. This eliminates long-term printhead wear and helps restore crisp print quality if the printer has sat unused for extended periods.
Frequently Asked Questions
Does the Lexmark 26 cartridge contain the printhead mechanism?
Yes, the Lexmark 26 (10N0026) cartridge is designed with an integrated printhead built directly onto the cartridge body. Replacing the cartridge completely renews the print nozzle array, preventing persistent nozzle clogging issues that often affect fixed-printhead printers.
How does colour ink consumption work when printing black text?
Depending on print settings, the Lexmark Z645 may blend cyan, magenta, and yellow inks to create composite black text if a dedicated black cartridge is not present or selected. Selecting greyscale or draft mode in your print driver helps preserve colour ink when printing monochrome documents.
How can I keep a Lexmark 26 cartridge from drying out during low usage?
To prevent ink from drying on the nozzle plate, always turn off the printer using its power button rather than a power board switch. This allows the printer to cap the cartridge correctly in its home dock, keeping the nozzles sealed against air exposure.
