Frequently asked questions about printer ink and toner

Q: My printer says it's out of ink but the cartridge still feels heavy. Is there really ink left?
A: Often, yes. Most printers stop printing based on a chip-tracked page count, not actual ink-level sensing. Inkjet cartridges typically have meaningful ink remaining when the printer reports empty. You can often continue printing for a while by acknowledging the warning, though print quality will eventually decline.

Q: What does "page yield" mean and how is it calculated?
A: Page yield is the estimated number of pages a cartridge can print, measured under the ISO/IEC 19752 (mono) or ISO/IEC 19798 (color) standards using a fixed test page at roughly 5% coverage per color. Real-world yield varies based on what you print — heavy graphics drop yield significantly versus plain text.

Q: Why is my printed text faded even when I just installed a new cartridge?
A: The most common causes are (1) the protective tape or seal wasn't fully removed, (2) the print head needs cleaning via the printer's maintenance menu, or (3) there's an air bubble in the cartridge. Run a head cleaning cycle once or twice and try again. If issues persist, the cartridge may be defective.

Q: Should I leave my printer on all the time or turn it off between uses?
A: For inkjet printers, leaving them powered on (or letting them go to sleep, not powered off at the wall) is generally better. Inkjets run small maintenance cycles automatically, which keeps the print heads from drying out. Hard-powering off frequently can cause clogged nozzles, especially for printers that sit unused for days at a time.
