Igor, I remember reading quite, a while back that the Epson printer should
be turned off at the printer switch, not from a wall switch or by
unplugging. DOn't have a reference for you and don't know if that's the
reason for your issue.

Subject: Technical question about Epson jet photo-printers
I've been using Epson R2880 for close to 5 years now, and one question is
still not quite settled in my mind:
Q.: When the printer is switched off, does it do anything special (e.g.
parking the printing head in a particular place/way) that minimizes
clogging of the nozzles?
Here is the background for this question.
Fact 1. When you turn the printer on, it initializes itself in a
procedure that includes using some portion of the ink. (I derive this from
the fact that sometimes after that the status of some ink cartridges can
change from full to "alarm-pre-empty" or from "alarm-pre-empty" to
empty".)
I am not sure if this procedure is waisting as much ink as the one that
initializes [unfortunatly all(!)] cartridges when you replace any of the
ink cartridges.
(If someone knows an answer to this question, I'd appreciate it as well.)
Fact 2. Over time the ink left in the nozzles of the printer head can
dry. Nozzle-cleaning procedure that is available through the
printer-driver utilities helps to unclogg the nozzles, but waists a lot of
ink.
When you leave the printer turned on between printing sessions for a
certain period of time, T, you can avoid waisting ink for startup
initialization, but go into a danger of getting nozzles clogged if T is
too long. So, what is the optimum time T?
While I don't expect an exact quantitative answer, a factor that
contributes to this is the question I formulate at the very beginning,
as that would tell me if turning the printer off reduces the probability
of the ink drying up inside the nozzles, thus clogging them.
I'd appreciate if someone knows the answer or has some clues or links to
the resources with such.
Thank you,
Igor
