Thanks Nick, The (tech, not sales ) rep was referring to the 9800. 4ml x 8inks would be 36ml.
All the same , that figure is disturbing. I'll have another go at him.
So far I have been able to avoid power cleans but have been assured (not by reps) that they work in difficult situations.
Marty, I have both 4000 (unpressurised) and 9800 (pressurised) printers and find they clog at about the same rate. I do use the big printer a lot more, so that could be an explanation. There are a lot of factors at work. The more startups, the more minor cleans. The more cutting of cotton papers the more crud. I seem to remember Mark DS finding less clogs on a 4800 than a 4000. Both are unpressurised, but inks (except MK) are different. Perhaps it's the ink difference, but the K3 inks are denser, so maybe its the heads or differing firmware, or or or?
I'll just be glad when inks don't clog and still dry quickly.
The air clean is a good idea. I'm a bit wary of squirting bottled stuff in the printer though. Perhaps you use a compressor with an oil filter? I've considered vacuuming with one of those little car units.
I, and I'm sure others, would be interested in any cleaning techniques that avoid litres of ink in the bin.
