It may be low. Most printers only operate when all the tanks have ink them. Inkjets are notorious for this as the ink in them can dry out after 2 years of inactivity. Refillable tank printers (non-cartridge based, non-toner based) can dry out in their tank clog the injectors of the printer too. If the ink remains in the print head over two years, you might need to run a head cleaning through the tools of the printer software to clear it up. Sometimes this is impossible, and getting a new printer is your only option.
