Common Questions About This Test
- How many cleaning cycles should I run?
- Start with one cleaning cycle, reprint the nozzle check, and repeat only if lines are still broken — avoid excessive cleaning.
- Can a nozzle check fix streaks in photos?
- It diagnoses clogged channels; if lines are broken, cleaning or cartridge replacement usually fixes photo streaks too.
