When a Low Ink Warning Display like this "?" is shown in the BJ Status Monitor, it means that ink level and ink counter are not matched.
You need to reset the ink counter from the printer driver when you replace the ink tank.
Note:
When Display a confirmation message of ink tank replacement is selected, a message asking whether or not the ink tank has been replaced is automatically displayed whenever the ink tank is replaced.
Turn the low ink warning off until you replace the ink tank to stop the warning message.
1. Ensure that the printer is turned on.
2. Open the Printer Properties dialog box.
3. Click the Maintenance tab and then click
Low Ink Warning Setting icon.
4. Clear a check box of Display low ink
warning off and click Send.
5. When the confirmation message is
displayed, click OK.
