Changing ink cart during printing ruins print head
I have had this problem twice now. We have been printing a job and an ink cartridge runs out half way through the print. Never good. I can understand that the print is now toast. My problem is that this also seems to ruin the print head too. Anyone else experienced this or am I just being tight trying to wring the last few drops out of a cartridge rather than just changing before a job?

printer should stop before running cart completely empty unless the safe guards have been bypassed and cannot see why even running the head dry would ruin it normally it would just require ink being drawn up to from new cart and then set it to heavy clean. What machine are you running?Kev

Had exactly the same problem on the same machine, normally once the cart symbol changes to a cross I keep an eye and once its less than 30ml left I swap the cartridge. The one time i missed it the ink ran out during a print (very obvious) stopped the print, changed the ink and started again and head never worked again.
I think it is more about the damage done running the head empty and the time it takes to draw the ink back up the tube to the head.
Now I make sure I keep an eye from the time it starts flashing.
Also had the same problem as you with head 1 failures under 200ml but its been resolved now.

What machine is this ?
We have a VP 540 and used the trick learnt on here the other day to finish a print, which is to cut off the stop tab. But this is after the machine stops to tell you a cartridge is empty.
