HP Ink System Failure: Ink System Failure
Also shows as: System Supply Problem; Supply System Problem
HP says this message points to a problem with the ink system, such as blocked cartridge vents, cartridges with no ink, or a printhead that is not making good contact.
What to try
- For HP 178, 364, 564, 655, 862 and 902 to 935 cartridges: clean each cartridge vent with a pin to remove debris or label glue.
- For HP 932, 933, 936 to 938 and 950 to 969 cartridges: shake each cartridge to check it has ink, and replace any that are empty.
- If your printer has a printhead latch, reseat the printhead up to three times with the printer unplugged.
- Reset the printer: power off, unplug from the wall for 60 seconds, and plug directly into a wall outlet.
- Install a full new set of cartridges.
When it needs a technician
If the error remains after these steps, HP says to contact HP Support to replace the printhead or service the printer.

First steps for any printer error
- Write down the exact code before you do anything else — similar-looking codes often mean completely different things.
- Power the printer off, unplug it for a couple of minutes, then power it back on. A surprising number of transient errors clear here.
- Open the covers and check for paper scraps, packaging material, or anything blocking the carriage.
- Check the cartridges or tanks are genuine, correctly seated, and not empty.
- Confirm the printer is plugged directly into a wall outlet, not a power strip or extension lead.
- Check your model’s own manual — codes are model-specific, and the manual is the authority for your machine.
