What does your nozzle pattern look like? Are you printing in text, vivid, photo, etc.? What level of ink are you using?
Once we know your settings, we can help a little better.

There would be a couple of things i would suspect.Humidity could be a factor. Check your Hygrometer (don't have? get one). This time of year, at least in my part of the county, humidity is a constant battle. I keep mine at around 40%. If you are at a higher elevation you need to keep it higher than that. If this is not the issue and you progressivly get worse during one session, you could have a starvation problem. Make sure you have a fairly full cartrige. Sometime I'll get a little starvation at the end (when the weight is below 100g). If your cart is full and a head clean or purge doesn't keep things open, check dampers. You can remove, clean them out using distiled water. Flush both ways untill the screens are clear and re-install. If your machine sits alot, you may wish to do this with all your channels.
i had the printer in a controlled environment w/ humidity and heat. i tried moving it to a much smaller room and so far its been running great on port authority tees. thanks for the help
