Hi Dana and thanks for the reply.
The 3800 was bought second or even third hand in September and the inks used were the ones I got off you that month. Prior to this I was using a 3880 and swapping between colour and Piezo K7 but it got too much of a hassle so I went for a dedicated K7 printer- the 3800.
Results from the 3880 set up were good for a newbie like me, the change has occurred with the 3800.
I have been following the IJM recommendations and shaking the cartridges weekly, with nozzle checks and power cleans when not likely to be used for a week or so, and if left longer have been letting them sit with Piezoflush.
I don’t think these cartridges were purchased from you, but I will be getting some more anyway as a couple of the 3880 ones look like they have leakage in the inner bag- I’ve been reading up on this in other forum threads.
I have already printed the QTR Calibration mode chart ( last night ) and when I come to terms with my new i1 will read the 60% patches.
There IS a possibility of ink contamination despite my best efforts to keep a clean and thorough work flow from loading the ink, installation and onwards.
So, shaking both the bottles and the cartridges should alleviate pigment settling even with half full bottles? and of course some power cleans and test prints to clear the lines.
If it looks like incorrect installation ( AAARGH!!!) what is the best way to determine which inks are involved? and what is the remedy- drain and flush just those cartridges or dump them and start afresh?
Finally, any news of 2016 workshops? Albany Western Australia is about as far away from Vermont as you can physically get on the planet, but then again…
