Updated May 27,2026

Each horizontal line in the nozzle check pattern represents the status of a nozzle. The color of each line corresponds to the nozzle’s color channel.

Scenario	Description	Impact on print quality	Recommended action
All lines are complete	All nozzles are functioning properly.	No impact.	No action required.
A few non-continuous lines are missing	A small number of nozzles may be partially clogged.	Usually minimal impact if missing lines remain below 1%.	Continue printing or monitor the condition.
Continuous missing lines	Multiple adjacent nozzles are clogged.	May cause horizontal banding or missing areas in prints.	Perform nozzle cleaning.
Large areas of missing lines	Severe nozzle clogging or poor cartridge contact.	Significant print quality issues.	Clean the print head and check cartridge contacts. Replace the cartridge if necessary.
Crooked or misaligned lines	Dust or particles may be blocking the nozzles, causing angled ink spray.	May cause blurry or distorted print results.	Wipe the nozzle surface with a lint-free cloth. Replace the cartridge if the issue persists.
