Solved!

HP Photosmart C4780 Firmware Update Fail

HP Recommended
Photosmart C4780
Microsoft Windows XP

I have downloaded the firmware update "C4700_FWUpdate_4362_HPCOM_v1" but every time I try to install it the wizard says my printer is not connected.  In fact it is connected by wireless and USB cable.  I can print to it, the Print and Scan Doctor sees it and verifies it is OK.  The HP Digital Imaging Monitor reports it is OK.

 

The printer is running its original software and functions OK, except for the occasional poor response to control panel inputs which this firmware update addresses.

 

My Device Manager shows all appropriate drivers OK and my Control Panel shows the printer OK.

 

Any thoughts, please?

Turn off the wireless radio and connect via USB cable only. Verify you can print and then try your firmware update.

Thanks for the input.

 

Now, do I have to turn off my router or is there a way to just turn off the radio in the printer?

I would turn off the radio in the printer to be sure. Then use the computer and USB.

OK, so I'm embarassed to ask...

 

How the heck do I turn off the radio in the printer?

 

I can't figure out how to do it through any software on my computer, unless I'm missing something basic...

 

Is there a way to do it on the printer itself?

 

Feeling so rookie here...

Most likely through the front panel menu buttons. You'll have to look to find it.

Or... like you said, turn off your router to disconnect the wireless. Now upgrade the firmware through the USB cable.

Good news - I found the front panel wireless menu and turned of the radio.

The wireless icon went out.

 

Bad news - the printer went into an endless loop of the progress bar on the front panel, with periodic flash of the standard Scan, Copy, Print  display, then back to the progress bar loop.

 

I occasionaly hear the cartridge control carriage move a little, but nothing else.

 

I have pulled the power cord to do a hard restart with no luck.

I have pressed and held the power button and got it to power down with no effect.

 

Any thoughts????

Yeah, I've tried various reboot configurations and get sort of random responses in printer restart sequence.

 

Feels like it needs to have its BIOS re-flashed....

 

Any way to do that or re-install its programming?

 

Or am I seeing a hardware issue?

 

Would you try to fix it or recycle it?
