A:AnswerFrom my experience the non "XL" cartridges print about 300-400 pages. However, if the expiration date runs out, they will stop working. You will get a message to replace them with original HP cartridges. HP printers REALLY HATE generic or refilled ink cartridges. If you attempt to get help through the HP chat or phone service, be prepared to provide the numbers and expiration dates on your ink cartridges!
