If I'm not going to print on my R1900 for a short while, but not long enough to warrant inserting cleaning carts, I will often print the occasional calibration chart on plain paper to keep the ink flowing and cartridges agitated. I do so at 720 dpi to conserve ink. Is there any benefit in doing so at 2880 dpi? I am assuming that all nozzles are used at 720 dpi, but given problems that I have had in the past with clogs I wondered if that assumption is correct? Sorry if this is a dumb question.
(As you will see from my order history, I have just ordered and installed fresh inks and carts, and so am not having this problem at the moment. But it just occurred to me that this might have been an issue.)
