Why is my printer not working after replacing ink cartridges HP?
Perform a head cleaning on the printer, if available. Try resetting the ink cartridge counter. Consult your printer’s documentation to get instructions for your specific model or check the manufacturer’s website for help. Verify no software errors are occurring and try printing a test page.
Do I have to replace both ink cartridges on my HP printer?
Printer cartridges can be replaced on an as needed basis! If one cartridge is running low, you do not have to replace the other colors at the same time. However, you do need to have all of the printer cartridges installed in the printer for it to work.
