I have a power meter in my home that shows actual usage. I tried switching my 4800 off for some time and on again to see if what you were saying was true or just a thoughtless quip. The meter refreshes every ten seconds and records kw/hr up to three places of decimals. It could not detect the difference between sleeping and off.

From "mad man chan" himself.
The following is from his web site on the 3800
Should I turn off my Epson 3800 when not using it or leave it on?
Executive summary: If you print daily (i.e., the longest time elapsed between two successive prints is at most a day), then leave your 3800 on. Otherwise, turn it off.
The following more detailed explanation is summarized and paraphrased from a thread on the Epson Wide Format Yahoo newsgroup, where the original poster spoke on the phone with an Epson engineer in the wide format printer product group.
According to the engineer, assuming a properly functioning printer, there is no difference in the parked position of the print head, whether the printer is on and the head is parked or if the printer is shut off. The engineer recommends that if printers are used very frequently (hourly to daily at the longest) then it is fine to let the printer stay on because there isn't enough time between prints to let the print head dry out.
To avoid problems with print quality, you want to avoid the situation where ink dries in the print head. In other words, dried ink is the enemy: it can cause clogs, and because it doesn't seal nozzles as well as liquid ink does, dry ink can contribute to air bubbles. If the printer is not used at least daily, then it should be shut off between print runs. The reason is that when the printer is turned back on, it goes through a special type of head cleaning (using a supposedly "minimal" amount of ink) to clear off the dried particles, get rid of air bubbles, and get the liquid ink going again.
The frequency of this special cleaning mode is controlled by the printer itself. It will be done occasionally even if the printer is left on; however, it is not done frequently enough if the printer is simply left idling while powered on and not being used. Hence, the Epson engineer's recommendation is to turn the printer off when the time between two successive print runs is longer than a day.
This advice I have always followed and in two yaers have had any problems.
I only print in batches and not every day.
Regards.
Richard

We have digital power meters to that you can see on line but they are not so detailed that you can see a difference if you turn on a light and off again. You will not notice anything in a minute or two. After a month, it adds up. You are not going to see differences at kw/hr units. We get power bills every two months and that is when we saw the diff.

You will probably save about the same power as it would to boil your kettle twice. But I'm all for saving energy so you turn it off. My meter is brilliant and does show the change (after a lag of ten seconds) when you switch appliances off and on, it is a real eye opener. I similarly found that turning my TV, video player, cd player and sound system off at night saved very little. If you can save five minutes of kettles, washing machines, ovens, any heating device and vacuum cleaners they will out do anything by a factor of hundreds that switching your printer off will save, it's just a non starter I'm afraid.

YOu must have one of those old tube TV's . It's pretty well documented that LCD TV"s (especially the big 50 inch monitors) etc... have increased peoples electricity bills.

There was some talk in CA about not selling any TV over 50" for the power issue thing. I don't know if they did away with it or not. Sort of like the upcoming 100 watt incandescent bulb issue in favor of the mercury-filled fluorescent which occasionally burn up and flame out from a bad ballast winding like ours did. A flame coming out of the top of your lampshade will get your attention. We had a bunch of in-ceiling fluorescent fixtures flame out at work and soot all around the ballasts so some burning goes on there as well and I believe their is a electrical code over how far they can be from flammables. But I digress....
I know our Mitsubishi TV has three modes of power: Some sort of "Always on standby." Full on. And "Vacation" which is also a "Full Off." Really dumb part is the "Reset Button" for when it goes nutty on power up - like no screen and only sound. "Reset" on a TV is a bad implementation of design, imho.
I would suspect Epson would have added a "Standby Mode" if they felt the thing shouldn't have been shut down after use for a day.

And of course there is a standby mode!
As for the horrible cost for electricity to leave a printer on, it is fairly easy to calculate the cost exactly. An Epson 4880 will cost me less than $5 per year to leave it on continuously.
I pay a premium for electricity. It may be cheaper elsewhere.
The instructions at the end of the R2880 manual clearly say to un plug the machine if not used for "long periods".

Almost every electrical item that you buy will advise that. It' just so that If you've left it on and it over heats one day and sets fire to your home, that the manufacturer's can't be sued and can say I told you so .

Well just exactly how much per KwH do you pay for electricity? Previously I showed that for $0.10 per KwH the cost for an Epson 4880 is less than $5 a year. If your electric rate is 20 cents per Kw Hour, it would still be less than $10 a year, assuming the R2880 is like the 4880 and draws all of 5 watts when idle.
Unplugging when it will not be used for extended periods is very different than turning it off when not being used. "Long periods" means many months, and unplugging is radically different that using the ON/OFF switch.
The only time the User Manual indicates it should be turned off is if it will be unplugged.

LCD TVs are not the big user of electricity. Plasma models use the most. LCD is middle of the road and LEDs generally use the least.
By screen size, Plasma TVs actually use more power then CRTs. LCD and LED use less than a CRT by size, but are usually much larger than the CRT that they replace.

Jules, you live in a place that has a high technology meter that can show little fluctutations in electrical power use in your home almost instantly and do you think your government that installed those wants you to leave electrical appliances ON? If you leave your printers on 24/7 just because you think that is going to prevent clogging or problems then you should be ashamed of yourselves.Think of the environmental costs..if everyone does that...the CO2 in the atmosphere. Even Google is adding CO2 to the atmosphere. Wake up and use your brains.

Aristoc. The government installed nothing in my house, I live in the UK! 
I actually don't think the government is bothered how much power I use. I do however, as in the last few years my gas and electricity bills have rocketed. Not so much I believe to any other reason than powere companies being greedy and massaging their facts to suit themselves. So I am not ashamed of myself thanyou very much. I have also been an environmentalist since the mid seventies and not wasting anything has always been my mandate.
Perhaps you misunderstood what i was saying, the printer in your home uses a very small amount of power and over 90% of what you use and can have great savings made if you are clever is heating things with electricity such as kettles and water heaters, plus electric bar heaters etc. Getting a meter, which I bought privately (get an OWL on eBay) really pinpoints what in your house drains the power and costs you most of your bill.
Is that clear enough?

I think what Aristoc really meant Jules was if you stuck the meter in your ear, you would be able to measure the electrical activity inside.
Think that is known as the "Brain Drain"
On a reference point (well ..... as I am here ....) I have always left all my printers ON for the past 12+ years. Except, of course when OFF - when away for breaks.

Get a grip on it. The huge waste of power you are talking about is 5 watts .
I don't know about your 2880, but the Service Manual for the 38xx series says this:
- 25 watts Operating
- 5.0 watts Standby Mode
- 0.3 watts Turned Off
- Less than 59W Operating
- Less than 5W Standby Mode
- Less than 1W Turned Off
If it hasn't occurred to you yet, 5 Watts is minuscule compared to dozens of thing you needlessly run in your home every single day. Just the startup surge when the compressor in your refrigerator starts is greater. Do you turn off the fridge each night because nobody is going to open the door? How about fans that circulate heat in your house? Or circulation pumps for baseboard heat? Do you turn off you Wifi server when it isn't being used? Do you use 15 watt nightlights? How about hall lights? The list goes on and on and on... and printers in standby mode are pretty much right at the bottom.

Yes Zone, that is why i suffer from Tinutus! The Peter Frampton concert i went to earlier this week was great, he used loads of electricity.
And likewise I leave my printer on except when it's off, and then it's ...off.
