I need to find the grey power cord for my HP Deskjet F340

Computer equipment stores should have those 3 prongs power supply.
Radio shack sells them as well.
It does not have to be gray as long their the same size plugs. 95% at a time they are compatible.

I hope this helps.

Power cord is damaged and needs replaced

i am not in any way offiliated with the following website but it was the first one to come up in google,Printer,Part,09572119.aspx

bearing in mind the part is quite cheap there must be lots of places you can obtain a spare/replacement power supply...and if they are sold seperately the clerk that gave you the advice about not being able to replace just the power cord must have been having a bad day/year/lifetime

F340 printer

Hi Pear,

I'm sure that this is an Hardware issue, this could be fixed by resetting the printer.

Step 1: [Power Drain]

>>Turn off the printer by disconnecting the power cord from the back and also disconnect the power cord from the wall outlet

>>Then Press and hold the ON button for 30 seconds.

>>Connect the power cord, if it did not work go to step 2.

Step 2: [ NVM Reset]

>>Take out the Ink Cartridges out.

>>While the printer is on, unhook the power cable from the back of the printer.

>>Press and hold CANCEL and PLAIN PAPER button simultaneously, while holding these two button insert the power cable and keep holding for 10-20 seconds.

>>Release the button and check the printer.

>>If the problem exist, service or replace the printer by calling HP.

HP deskjet f340 all in one printer

its the problem in your adaptor for sure.but before going for the new adaptor please check the jack of the printer where you connect the adaptor is loose or slightly pressed inside or looks any thing like damaged.if not then try in another electric outlet.also try with different power cord wire which you connect in the adaptor the three pin adaptor.that is near about less then 2$ if you want to replace.and if still does not work then its the adaptor you have to replace.that will cost u near to $10.
