See the "Environmental Characteristics" listed for the Epson 7900, for

Storage -4° to 104°F (-20° to 40°C)
Relative humidity 20 to 80%
Operating 40 to 50%
Recommended Storage 5 to 85% (no condensation)

If it's winter, and your inkjet is in a room at 45° F and 90%
humidity, one
should expect that the device's behavior will be affected.
Actually, in a heated building in a cold cliimate, RH normally
plummets dramatically. There's only so much additional moisture one
can add with a humidifier before seeing condensation on windows and
walls. I'm about to purchase a new wide-format inkjet printer, and
have had to rule out the Epson 7900/9900 based on the the published
Epson specifications (which you have also kindly posted here). I'm in
New England in a historic building with "Balloon timber" construction
that offers no place to insulate within the walls. Adding humidity to
the room temperature air in the dead of winter would cause massive
condensation within those walls and damage the building. The indoor
humidity in my studio at the moment is about 25% and will drop further
to less than 20%RH in January and February when it can get bitter cold
outside. The Canon ipFx100 series printers are spec'd to operate
properly at 10%RH, Hp Z3200 series at 20%. To run the Epson model at
40% operating conditions, I'd need to find an interior room and vapor
seal it, then humidify it, but I don't have that option. Likewise, I
could tent the machine and keep a 40%RH microclimate in the tent
surrounding the machine, but that's more work and not very convenient,
so the Canon is probably going to close the deal. That said, it's not
just printer operation that factors into this situation. Papers and
inkjet image receiver coatings are very hygroscopic and will contain
significantly more moisture content during summer than winter once
they come to equilibrium with their environment In a typical four
season climate. The paper moisture content affects the penetration of
the ink into the paper as the paper initially receives the ink. The
effect is more pronounced for dye-based systems than pigmented
systems, but nonetheless, a factor contributing to calibration state.
