Does anybody know its value ? color code seems to say 47µF or maybe 4.7µF ... ?
How to check and fix that power circuitry ?
I would like to get it working our of a standard 5V DC USB style power, would be great.

Thanks for advices

The power supply circuit is probably the same, so C6 is listed as 47uF and is a tantalum type.

There will be a fair bit of current draw if the printer is used so the USB will have to capable of supplying this.
