1320's are a fickle beast. (I am fighting one right now)
1) Clean the contacts
Check that your contacts between the printer and the drum unit - give them a decent cleaning.
2) Manual calibration...
create a one page word document, completely filled with text - send it to printer for 100 copies. Someplace around 50 to 70 pages, unit will recalibrate. Hopefully, it will resolve.
2a) If toolbox is installed, I believe you can run the calibration diagnostic through that too.
3) If the above doesn't work, the PHD (drum unit) is probably bad. replace it.
