The SendPro® 300 is displaying a "Low Ink" or "Ink Out" message or the error code P2B03.
The meter is out of ink.
If the message is “Low Ink", replace the ink cartridge soon. You can print approximately another 300 impressions or leave the system running for six days without printing.
If the message is "Ink Out”, the ink supply is completely gone. You will not be able to print any postage until you replace the ink cartridge.
If you need ink, order a genuine Pitney Bowes replacement ink cartridge:
