If you have just installed a refilled, remanufactured or compatible HP 940 or HP 940XL it is likely that it uses a HP original chip to identify itself to the printer. These chips use a combination of counting pages and average page coverage to estimate the amount of ink inside the cartridge. As they have no way to check the physical ink level in a cartridge, a chip that has been used previously will almost certainly give a HP 940 low ink warning stating is either has either very little ink or even being empty once installed. The message should look similar to the one shown below:
To continue simply click OK in the bottom right of the message. As your printer will not warn you when the ink is running low we recommend keeping an eye on the quality of your prints and replacing the relevant cartridge when a colour begins to fade.
These cartridges are compatible with a variety of printers including:
