Show stop conditions
- Ink is leaking inside the printer
- The printhead becomes unusually hot or the printer reports a hardware code
Likely causes
- Black ink is empty, expired, blocked, or not recognized
- The black printhead nozzles are dried or clogged
- The cartridge vent or protective seal is blocked
- The driver is using an unexpected color or media mode
Quick checks, in order
Print the built-in quality or nozzle test
Use the printer control panel, not a document from the computer.
Check cartridge level, vent, and seating
Remove only as directed by the model manual.
Run one normal cleaning cycle
Excessive repeated cleaning wastes ink and can overheat some heads.
Stop before solvents or manual printhead power tests
Use only manufacturer-approved cleaning procedures.
What does the test pattern show?
Focus on the black cartridge, vent, ink path, and black nozzle section.
A controlled nozzle cleaning and alignment may help.
Check the app, driver, grayscale, paper type, and selected printer.
Stop and get qualified help when
- Ink is leaking inside the printer
- The printhead becomes unusually hot or the printer reports a hardware code
Official support and model manuals
Use the full model number from the rating label. The manufacturer manual is the deciding reference when codes differ by region or product family.
Frequently asked questions
Should I run cleaning ten times?
No. Run the manual’s recommended sequence and allow rest periods; repeated cleaning consumes ink and may not clear a failed head.
Can a full cartridge still fail?
Yes. The vent, chip, ink outlet, or printhead path can be blocked even when the level appears full.
