**Page yields are declared by the manufacturer in accordance with ISO/IEC standards or occasionally estimated based on 5% per page coverage. Yields will vary greatly depending on image, area coverage, print mode and environmental conditions.
Each time that you have to purchase cartridges and supplies for your HP Envy 7640 e All-in-One Printer, you'll find yourself having to make a choice. That choice is between genuine inks that have been built and approved for use with your printer by HP and third-party alternatives. The latter option can look appealing if the only thing that you take into account is the price of buying the ink. However, there are many other things that go towards determining the cost of printing each page that you should be sure to consider before making a decision on what to purchase.
As well as the price of the cartridge, you'll want to consider the yield rate (generally higher on manufacturer-approved inks), the quality of the print and the environmental reputation of the manufacturer. You'll also want to be sure that there's no chance of your cartridge causing damage to your printer, as has been the case with some third-party inks in the past.
As with most printers, the HP Envy 7640 e All-in-One Printer will print most quickly when it is in draft mode. Some third-party inks will produce very poor quality printouts when used in this setting. This can mean that a higher quality setting must be used in order to produce acceptable quality printouts. This can increase the cost per page printed until it's higher than it would have been had manufacturer approved ink been chosen. This shows how important it is to take every factor into account when you are buying ink. Genuine inks produce better quality documents, print for longer and are specifically designed for your HP Envy 7640 e All-in-One Printer, making them the obvious choice in many situations.
