Hi Igor -
A few months ago I updated to an Epson 3880 from a 3800. One of the few
changes between the printer models is that the 3880 now parks the heads
and shuts itself off after a few hours of inactivity. Looking at the
configuration menu, my printer shuts off after 8 hour of idle time. Sine
I have not changed it, that would be the default setting for this
printer. The options are for it to shut off after 4, 8, or 12 hours.
The best time probably depends on the conditions in which the printer is
operating - relative humidity, temperature, etc. In the case of the 3880
it seems that Epson picked 8 hours as the baseline.

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
