❓ Quick Answers

Q: Black cartridge is new but still won't print?

Remove protective tape from new cartridge. Run initial charge cycle. Some new cartridges need priming.

Q: Cleaning makes it worse?

Stop cleaning after 3 cycles. Excessive cleaning can introduce air bubbles. Wait 6 hours and try again.

Q: Test page shows black but documents don't?

Application-specific issue. Try printing from different program. Check PDF settings for "Print as Image".

Q: How long can black sit unused?

2-3 weeks maximum. Print one black text page weekly to prevent clogs. Color inks can sit longer.
