printers and humidity

A few weeks back I was asked about clogging issues, so I thought I would address it here as well.
If you have an Epson you have cerainly encountered clogging. It can be horrible.

A few things I do to help the situation:
1>Keep the office dust free(Air purifier)
2>Do a nozzle check at least once a week
3> ideal humidity

Most people that I have talked to don't think about humidity but this can be a the biggest factor in clogging. I am in Colorado and it is dry!

Epson recommends:
Epson 4800 -
Operating: 20 to 80% relative humidity
Recommended 40 to 45%

Epson 3800 -
Relative humidity 20 to 80%
Operating 40 to 50%
