Well it seems like you folks are the experts after all!
Today I wanted to inspect my HP C4180 a little closer.
I couldn't find a way to open it up completely but I did remove the cover to the memory slots at the front left of the printer. No hard drive or anything obvious was there.
Now here's what I did. I went into the next room where the CPU and plug for the printer is. I plugged in the printer and listened to the high pitched hiss coming from the power adapter (that's why I located the plug in the next room).
Then I went back to the other room where the keyboard, monitor and printer are and put my head close to the front left corner of the printer. Sure enough the sound that I heard last night (after talking with the tech girl) that sounded like a hard drive was the same sound coming from the printer's power adapter, only half or a quarter as quiet. I couldn't hear anything else from the printer.
So that's pretty well satisfied me that there isn't a hard drive in it. I'm relieved about that.
That tech support girl scored a big 0/2 then.
I called with a basic question about the On/Off switch. I told her that it didn't seem to be behaving properly and asked her how it should behave.
I said when I press the On/Off switch to turn it off, it very often doesn't turn off, but instead re-initializes. I asked her how long I should be holding down the button to turn it On and Off. Nothing mentioned in the user's manual.
She said I should hold it down for 4-5 seconds to turn it On and Off.
While we were waiting for the printer to initialize, she started telling me about the various things that need to be intialized at startup and this is when she mentioned there is a hard drive in the printer and all HP printers now.
Well by the end of the conversation, after I explained what was happening each time I held down the On/Off button for 4-5 seconds to turn it off (the machine kept initializing) she concluded that there was a problem with the printer and advised me to return it to the store for an exchange.
After I got off the phone, I wanted to try one more time to turn it On and Off with a one second press. It worked. So much for tech support!
But not always. And that was the reason for the call. If I held it down for one second, sometimes it didn't turn off.
I am convinced that holding it down for 4-5 seconds starts an initialziation process.
So I guess I need to play with a 1-3 second interval to see if that will do it.
Who knows?
