Re: MACHINE DOES NOT SWITCH ON
You most likely have a bad low voltage power supply. They develop problems from heat in the power supply area. You can google a business called " the parts drop". Give Britt a call and see what he has. He will give you the best price .

Is this your problem: The power light and about all of the left lights are blinking and there is nothing on the display screen. Trying to turn off the machine does not work and results in the same error. "Hard" reboots do not work.
Switch the cords if you have another HP Photosmart printer, even if the latter one is still working.
I thought of this early but then decided to watse three hours of my life I will never get back,
Do you have another HP printer with a similar looking power cord?
The cords should go into the back of the printer very easily. I have an HP C5280 and a newer HP C309 and I just moved. Actually, I have three printers including an HP 7510. The 7510 and the C309 worked just fine when I set them up, so I figured they both had to be utilizing the proper cords. But I was sismaken.
I undid the C309 cord and replugged it and noticed it was hard to put into that machine, despite that it still printed, just as the one I was using on the C5280 was difficult to plug in. So I made sure the transformers were basically the same and switched the cords.
Your first tip that something is awry is if it takes any effort to get the power cord into the machine in the first place.
Try to Reset your Printer.Before that search for any paper piece or any other obstacle which preventing carriage movement. Full reset: a. Unplug the power cable from printer when the printer is powered on. b. Press and hold # and 6 while plugging in the power cord. c. Wait until "Semi full reset" displays ("Semi" appears despite the fact this key sequence is defined as a full reset). d. Answer questions - Language/country, etc.
Partial reset: a. Unplug the power cable from printer when the printer is powered on. b. Press and hold # and 3 while plugging in the power cord. c. Wait until "partial reset" displays. d. Answer questions - Language/country
Please remove all the cartridges, clean the Contact points on the cartridges and on the Printer with alcohol/spirit/acetone using a soft brush, don't touch the print heads, you may damage them.
Turn off the printer, disconnect usb cable, power cord and ethernet cable (if any). Leave it Off for few minutes (fix minutes will be enough), also remove/disconnect the power cord from the mains.
Do some cleaning if you can.
Now press the power button several times. Connect the power cord and power on the Machine without anything installed/connected, again leave it On for few minutes and turn it off.
Connect the usb cable and ethernet cable, Switch on the printer and install the cartridges. If there's no internal problem this will definitely fix your problem.
make sure that the housing that holds the cartridges are clean at the contacts, this can be done with the machine turned off and unplugged, clean the contacts with warm water and a damp cotton bud not wet and then dry it with a paper towel.
make sure everything is dry before turning the printer back on, if this doesnt work then it needs a service.
The printer is always on despite of the status of the front panel, to turn it off you have to disconnect the power cord. In some models of HP printers, the printer will power itself ON from "standby" when the PC sends it a printing job and go back to "Standby" when the job has finished printing.
