Help! I have read several sites with suggestions for fixing this problem, but nothing works. I have removed the glass and cleaned the inside, tried three different resets from HP, tried doing a diagnostic cycle by pressing the cancel and color buttons, then going through all the buttons as directed by the display. Several times I have disconnected the power cord from the back of the printer and plugged it back in, then when I hit the "on" button, again it starts to initialize and continues clicking until I turn it off. This has happened everytime we have a power outage for the last few years, and usually after about a dozen tries, it finally initializes and I'm in business. Not this time, though, and I'm ready to toss this machine. Any advice out there???? Thanks, JoAnn
I've had that EXACT same problem before. I suspect there is a sensor somewhere that tells the motor that the head is in full retract position but I'll be damned if I can find it! What you're hearing is the drive belt slipping over the motor gears because the motor won't stop but the head can't move any further. The moter works in timed phases so the sound is like a loud:
click,click,click,click...pause...click,click,click,click...pause...
Unfortunetly this a mechanical/electrical problem that can't be fixed thru the user interface.
Just wanted to add that I've been dealing with this problem for 2 days now. I've taken the printer top completely apart to watch what's happening. So far the only thing that seems to reset the head is to unplug from the back of the printer> wait 20 seconds> plug back in.
This seems to work (sometimes) so now I'm wondering if it really is a sensor screwing up or something else. I also found a way to do a BIG reset. Unplug from the back>wait 20 seconds>hold down the # key and the 6 key and plug back in. It seems to run a different reset routine. Good luck!

I too, have the same problem with the 4 click and a pause when the machine if first turned on. Like XerteX I took the machine apart and, specifically the top plastic unit that holds the glass. Setting the glass unit on the printer and turning it on I found that the "chatter" would cease as soon as I lifted the top unit straight up...when separated about 2 inches from it's resting point the chatter stopped. So there is a sensor part contained in that "box" above the head that reacts with the head but I had no success in pin pointing its location. Strangely enough, the printer has not chattered once in the past week since I put it all back together. Perhaps the removal action stimulated something in the sensor. Anyone have a clue as to thew function of this head sensor ?
Well, somebody mentioned the white stripe at the end of the glass which is like a STOP sign for the scanner lamp. Well, at one end of that stripe there are some letters and numbers for which I concluded they mean STOP and because I noticed that the lamp does not pass under it I shifted the lamp a little bit thowards them (one milimeter) and the thing finally worked. Is it possible that the lamp thru time or transport moved?? Anyway, if anybody elese has this problem try to do this!
For me, now I have to solve the problem with nonoperable software fo scanning.
Bye
I had the clicking problem during initialization, I reset as some of you have had limited success. Great - no clicking - but printer does print - I am dumbfounded

Thanks for your help. Unfortunately, nothing has worked, even the reset you suggested, so we are now shopping for a new printer. This one is 5 years old, so maybe it's time to move on even though it was a good printer when it was working. How sad these things just don't last as long as they should!
