Pro Tip
Always let the printer complete its standard power-down cycle using its own power button rather than a master wall switch, as this ensures the individual LC73 or LC77XL cartridge nozzles are properly capped to prevent air drying and micro-clogging.
Frequently Asked Questions
Can I mix a high-yield LC77XL black cartridge with standard LC73 colour cartridges?
Yes. This printer accommodates any combination of sizes from this cartridge series. You can install a high-capacity black cartridge to match heavy text volume alongside standard colour inks without encounter errors or physical fitment issues.
Why does my colour ink deplete even though I mostly print monochrome documents?
The printer uses small maintenance amounts of cyan, magenta, and yellow ink during automated printhead servicing cycles. This standard operational logic prevents air blocks and dried ink from compromising print performance, meaning colour levels slowly decline over time.
What happens if one colour runs out entirely while printing a text document?
To protect the permanent printhead from thermal stress and damage caused by firing empty nozzles, the printer will suspend all operations until the empty cartridge is replaced. Keeping a spare colour cartridge on hand ensures your primary monochrome workflows remain uninterrupted.
