I have a 4900 and a maint tank resetter with three tanks
When I try to reset the tanks the resetter flashes red then goes steady red. The tank is not reset. This happens on all three tanks
A few questions
Do I need to wait for the tank to read completely full before I reset it.
It has been a while since I have used the resetter I thought it use to show green. So what should the resetter show
Is there an o sternal battery on the resetter that may need to be replaced. Seems strange to have three tank chips go NAD all at once
O need to flush the printer but no tanks have enough space.
