Lexmark CS820, CX82x, & CX860 ? The Printer Locks Up When Waste Toner Bottle (WTB) Is Nearly Full

What you will see

A printer with its Waste Toner Bottle (WTB) nearly full will be locked up and show a red ‘X’ message in the Control panel screen if the Waste Toner Bottle Near Full notification has been changed from “Warning” (default) to “Non Continuable Stop”. Replacing the WTB or restarting the printer will not reset the intervention message.

Suggested remedy

If your printer is running firmware version 2, it is not recommended to change the WTB Near Full notification from its default setting to “Non Continuable Stop”. Changing the notification setting will cause the printer to stop printing and hang once the WTB is nearly full of waste toner.

The succeeding firmware release should correct this issue. In the event that the settings have been inadvertently changed and thus cause the printer to hang, following the steps below should restore the printer to ready state.


The “WTB Nearly Full” notification setting is not available from the printer’s Control panel screen. You need to access the printer’s Embedded Web Server (EWS) to perform the changes.

To access the EWS, open your preferred Internet browser and type the printer’s IP address on its address field.


Once you are on the EWS, click “Settings” on the left pane, and then select “Device”. Click the “Notifications” shown in the main window.
