Using an energy meter I measured the power consumption of the B205.
When on or in use, the printer consumes an amount of power that conform the specs.
However, when entering power save mode, consumption drops to 11W, which is 10 times the specs.
Moreover, when the B205 switches off, it still draws 11W. This is a pain, since the unit has no mechanical power-off switch.
Why does a printer draw even the slightest amount of power when it is not even switched on? It is not standby that it has to be able to respond to external signals (e.g. remote control, wake-on-lan). It is off.
If too much electricity is fed into the grid in relation to the quantity consumed, the electrical frequency increases. Since power plants are designed to operate within a certain frequency range, there is a risk that they will disconnect from the grid after a period of time.
Thank you for using the Support Forum. Make sure you have the printer plugged into a dedicated outlet and not a surge protector or power strip. This is the link to the electrical specifications. If you get the same results in a dedicated outlet please consider contacting your support centre for further assistance.
Thanks for the link. The specs match the specs in my user guide.
Basically, I have two questions.
First, how can you switch the B205 off. 'Off' meaning off -- zero power draw, just like physically disconnecting the power cord. (Hardware design issue?)
Second, why does it draw standby power (approx. 11W) both in sleep and power save modes. (Firmware issue?) Also, what is the use of sleep mode if it cannot be waken up without physically pushing a button?
I'd like to invite other B205 users to actually put an energy meter between the wall socket and the device and see what their readings are.
