Ink Empty - no warning!

[midnightmadman]

Is this a common problem with a Prismjet extra?
My black was starting to get very week in my prints and I thought maybe I had a problem. After doing some cleaning etc and no improvments I pulled out the cart. and it was completley empty! I usually get a warning message but nothing this time.

Mine on my Mimaki normally goes from like oh 15% or 20% to 1% in a minute whenever it feels like it. Really annoying. Hopefully you can figure that one out.

Occasionally my PrisimJet will run out of ink without warning. It is very anoying and waste alot of material.

Sounds like the 'dead man' sensor.

There is a sensor that is activated by the tab that sticks out when a cartridge is empty.

It is generally caused by the flag not sticking out of the cartridge telling the machine it is out of ink. Usually a fault of a defective cartridge.

Thanks everyone.
So the machine will just keep trying to print black and the head will run dry, correct!? I guess I better pull some ink through my waste lines?
Should I be worried?

Check the cartridge and see if the tab is working properly.
If it is, then it could be the actual sensor
