We purchased 7 HP Lab top computers and 7 C6380 printers from the Best Buy Store in Bowling Green, KY in June of 2009. We are going through ink cartridges like crazy with only a few pages printed. It is regular letter size print. We are having trouble finding cartridges at Office Supply, Best Buy, and Wal-Mart stores. We found out we can not refill these cartridges either. Do you have any suggestions on how we can solve this problem. Hopefully we want have to trade them for another brand but it is looking like this is our only salution. Thank You Director Jerry E.
