Greetings. I’ve just received a new batch of carts for my R1900. My old ones were rather old and I suspect starting to cause problems. I can see that the new ones are quite different to the old. Before I start to use them (with fresh inks as well), can I clarify the filling instructions?
On the first fill, the instructions for the old ones (date 2/4/2010) say to use the VAC method. That is, put the syringe tip without the drawing-up needle into the filling hole and pull the syringe up etc. I’m sure you know the drill. The new instructions (dated 8/14/12) for the new carts say to inject the ink into the fill hole using the drawing-up needle, with no mention of VAC. I just wanted to double-check that the VAC is not needed. I’ve made the mistake in the past of not using it when I needed to and you know the problems this causes. Assuming it’s not needed with the new ones, would it do any harm?
For refills, the new instructions say to leave the vent hole open when refilling. This surprises me, as it runs counter to my experience with carts from a range of sources and is quite different to the older 2010 instructions, which say to plug it. Why the change and what would happen if the vent hole was not open during refilling?
Thanks in advance for your advice.
