# How do I calculate the number of amps my laser printer uses? (1 Viewer)

#### Daniel Swartz

My laser printer has 2 sets of specs:

Low voltage:

100-127 Volts, 50/60Hz

Power Consumption: 330 watts operating, 85 watts standby, and 25 watts idle.

High voltage:

220-240 Volts, 50/60Hz

Power Consumption: 340 watts operating, 85 watts standby, and 25 watts idle.

Can someone please tell me how to translate this data into amps? Thanks!

Maybe I can answer my own question....

Does Amps = Watts / Volts?

So, given the specs above, the number of amps my laser printer uses will vary in between 3.3 (330/100) and 1.5 (340/220), right?

Correct. However, I'll assume that you have either 220 or 110 volt installation, so depending on which one, it will be either 0.8-3.0 A (110V) or 0.4-1.5 A (220V)

Just out of curiosity, why do you need to know? I've had a laser printer for almost 10 years and have never found myself wondering about how many amps it consumes.

Artur: Thanks!

Joe: It's actually X10 related. I recently added a workgroup laser printer to my office and now, because of the amount of power that the printer drains, my office X10 controls are all screwed up. So I need to buy a plug filter for the printer in order to screen out its noise. I was trying to see if I can get away with the cheap 5 amp filters or if I had to spend \$75 on a 15 amp one. =)

Ah, the joys of calculating amps for X-10 filters.

I hate X-10. As soon as I can afford it I'm dumping my significant investment (\$Thousands) worth of X-10 equipment and switching to real home automation hardware. After trying to actually USE X-10, I've discovered that it's just kiddie stuff...

It's too bad, because X-10 is nice and cheap.

Ryan: Do you have any recommendations on where to get the filters on the cheap? Thanks!

It really isn't that bad for the price. I've automated 5 rooms (lights w/ motion detectors) for well under \$200. I'm considering buying one of those drape controls as a last expense.

Then, I'm with you. I'll wait until I can afford the real stuff.

Ryan,

any thoughts on "real home automation hardware"? i need some lighting control for a dedicated theater, the walls are not finished, so it'll be like doing new construction.
