NOTE: “Empty” and “Low Ink” alerts are COMPLETELY NORMAL for all HP 940 & 940XL ink cartridges (tanks) which have been refilled! While at first this may be considered an unusual workflow, it does allow print operations to proceed. However, losing this feature is not necessarily significant, because the ink level indicator usually has substantial usable ink remaining when it shows “low on ink”. Ink level monitoring is primarily for planning purposes only – it is not required to support printing.
If you observe “Unauthorized ink”, “Counterfeit Cartridge”, “Non-HP ink”, “Depleted ink”, “Refilled Ink”, “Cartridge Warranty will be Void” or similar ‘nuisance/annoyance’ messages, you may ignore/bypass each message by pressing ‘Dismiss’, ‘Continue’ or ‘OK’ for respective ink cartridge, so that the printer resumes its normal operation. These types of annoyance messages should be expected when using refilled ink cartridges.
HP 940 Refilled Ink Cartridges – Low Ink Warnings & Alerts:
NOTE 1: HP does not allow an automatic reset of the electronic chip on the cartridge after a refill, so the ink level indicator is sending a false message that the ink level is low. Your cartridge is not low on ink, and nothing is wrong with your printer or cartridges. The ink level indicator usually cannot be manually re-set, so the ink level indicator is often not usable.
For any other cartridge error or printer alert message refer to ‘Solve My Problem’.

NOTE 2: A compatible, remanufactured or re-branded ink cartridge can be problematic; the smart chip (at base of cartridge) may not provide reliable printer-cartridge connectivity once installed. Compatible cartridges are typically purchased on-line or at select retailers (i.e sold under a different label than the regular HP cartridge packaging) and is essentially a “remanufactured tank” of the HP original/genuine ink cartridge. For the best refilling experience, only use HP original/genuine ink tanks.
