As an in-printer cartridge is depleted, remove it for refill. Keep a spare set of ink cartridges, for convenience. No ink residue should be on contacts – clean with lint free towel and isopropyl alcohol as necessary. If the problem persists then verify the HP 940 smart chip is present (see photo below for correct positioning) and ensure gold contacts are thoroughly clean. Following ink refill, if the HP 940 ink cartridge(s) is not initially recognized, then the check cartridge to printhead connectivity (remove and reseat the ink cartridges). If you cannot identify which color cartridge is empty, print a test page via: 1) your printer control panel or 2) via the “Test Prints” button below.Īs the electronics in the ink cartridge and the printer communicate with each other, sometimes the printer will incorrectly identify an ink cartridge as unrecognized or non-functional. You may need to activate it 2 or 3 times to reprime the ink port and PRINTHEAD. Initiate a “Clean Printhead” procedure, via the printer control panel Setup/Tools or Maintenance menu. If any streaks or missing colors appear on prints the cartridge may be suffering from an air bubble within the internal ink spout. HP 940 Refilled Ink Cartridges – Low Ink Warnings & Alerts NOTE: there is a sensor within the base of the cartridge that detects the presence of ink. When the cartridge ‘truly’ is out of ink the printer will stop printing and display a ‘replace cartridge’ error message or similar. The ink level indicator will falsely signal empty.Ĭontinue to print until the print quality fades. NOTE: “ Empty” and “ Low Ink” alerts are COMPLETELY NORMAL for original/genuine HP 940 & 940XL ink cartridges which have been refilled! While at first this may be an unusual workflow, it does allow print operations to proceed. After refills, the printer cannot track the ink level. Refer to important NOTE at bottom of page regarding the use of non-genuine/original ink cartridges. Press ‘OK’ or ‘Dismiss’ to bypass these prompts. Additional alert messages, such as “non-genuine cartridge”, “counterfeit, or “fraud” may also be displayed. Press ‘OK’ to dismiss this prompt and resume printing. Following HP 940/940XL cartridge installation, your printer/computer may show “ Low Ink” or “ Empty” messages.
