The actual ink usage will vary depending on how often you print mail, and whether you print many advertisements or inscriptions. The message Low Ink displays approximately two days before the ink runs out. Your meter will be able to print approximately 300 meter stamps. Or, you can leave your system running for about six more days without printing.
