One thing to consider is the amperage the cable is rated at for warranty issues. I believe the pioneer has 10amps..and some of the older printers might have a higher amp rating
A higher amp rating is a good thing!
If the Pioneer is rated at 10Amps then anything from a 20AWG power Cord to a 18, 16, 14AWG would be fine, smaller number = bigger wire Gauge = more Amps.
Most IEC Cords do not even list an "Amp" rating.
You are actually better off to match wire gauge to wire gauge.
It is the wire gauge or size used in the cord, that transforms to the "Amps" that it can carry.
"Amps" are what can heat up wires, if you have a 30 Amp Draw on a 15 Amp circuit and the 18 gauge internal wiring cannot take it, it heats up and can melt and start fires, that is why you have your Circuit Breaker panel and when it senses that you have overloaded the circuit and you are asking the wire to supply more "Amps" than it was designed for, It trips!
Also related to running a 18 gauge extension cord to an appliance or something that is drawing lot's of "Amps" through the wires, the extension cord can become very hot to the touch.
I think that most IEC cords for home use, Computer, Monitor, etc. use 18AWG wire. If memory serves, so is the Pioneer IEC 18AWG.
Always remember as I stated above, it is a smaller number AWG that equals larger Diameter wire, so if you want to increase the IEC cord to 16, 14 or even 12AWG all the better but not really necessary.
Just do not replace a cord going the other way as in a 12AWG with a 18AWG, that is NOT a good thing!
So in Summary, replace your Pioneer or any OEM Cord AWG to AWG and you should be fine.

From the table, you will see that:
18AWG is rated at 16 Amps. Probably in your House on a 15Amp Breaker
14AWG is rated at 32 Amps . Probably in your House on a 25Amp Breaker
Though recently there have been theories to wire whole houses with 12AWG gauge wire rated at 41Amps, it is not that much more than the smaller wire and much safer in the long run.
If I was building a house, it would be a no Brainer, 12AWG at least for the Outlets, because look at what gets plugged into home outlets today!
Sorry, went off topic a bit but you get the drift.
AWG to AWG for your IEC power cords or a smaller AWG....
Thanks for bringing that up ihbond!
Trust me, if you have a Warranty Issue, the Power Cord Police are not going to rush to your location to take pictures and see what "Power Cord" you have plugged into the wall!
Your doing this for you more than the Pioneer, my replacement cord is a 18AWG cord and will easily and safely pass up to 16 amps, plenty for the Pio at 10 Amps.
A very COOL Cord!
Have a Great Day and Week Everyone!
