"Waste Tank Full" or "Waste Tank Near Full" message on the DM100i-DM200i

Products affected:
DM100i / DM150i / DM200i (P720, P725)

Issue

The meter displays "Waste Tank Near Full" or "Waste Tank Full" error message, and may not print.

Cause

Excess ink from when the meter cleans the printhead and heavy use will eventually fill the ink waste tank in the meter.  When the ink waste tank nears capacity, the meter shows the message "Waste Tank Near Full".  When the ink waste tank reaches full capacity, the meter shows "Waste Tank Full".
