Mine does this too! It's driving me crazy! I want to take it back to Costco but I don't have my receipt! I will never buy an HP again! I can't believe I left Cannon

You can take it back to Costco without a receipt! I did. They keep the info on sales in the computer. Also, after hearing how long I tried to deal with HP over this, they took it back past the electronics return period, no hassle! I, too, will never buy an HP product again.

I've been having the same issue as everyone here. The printer simply goes into a coma after a while. I've tried increasing the power save value in the underware menu to 7000, but to no avail. Didn't want to try zeroing it out, due to one person's issue of bricking the printer.
So I looked for another solution that seems to do the trick. It's not a real fix, but a decent workaround that may work for many of you. It's quite simple, but requires having one computer remain on all the time (no problem for me since I have a home server running Windows). Here's what you do:
1. Make sure your power save timer is set to at least 7,000. Instructions for doing that are elsewhere in this forum.
2. Set up a task using the Windows Task Scheduler to execute every 12 hours.
3. In the task, add an action to run the command telnet using the arguments "hp133450.local 9290". Note, check your mDNS domain name as it may be different than mine.
4. Set up a second task to execute every 12 hours, but TWO minutes after each time first task runs. For example, if the first task is set to execute at 12 noon and 12 midnight, this second task would execute at 12:02 AM and 12:02 PM.
5. In the task, add an action to run the command taskkill with the arguments "/f /im telnet.exe".
What happens with each of these tasks is:
-- When the first task executes performing a TELNET to the printer using port 9290, this command actually queries the scanner for its status. If the scanner isn't busy, it returns a "00" to the telnet application. Doing this actually wakes up the printer without making any noise. The one problem with this is that the telnet command doesn't quit gracefully. There are probably some tricks to fix this, but I found a quick and easy way. That's the job of the second task...
-- When the second task executes, it kills the telnet task from the system. This prevents a build-up of telnet tasks in the computer that would eventually prevent the first task from working.
I have been running this now for a week and the printer stays alive. You can tell it works when the printer is in power save mode and once the telnet task fires off, the display lights up thus resetting the power save timer.
Hope this helps!!!
PS: I could have taken the printer back to the store, but I was too determined to beat this issue one way or another. I really didn't need to spend more $$$ on a printer since I don't use it very much.

I abandoned the process I explained earlier. The printer still went dead in power save mode regardless of periodically opening the scanner status port. It just took a bit longer. Since I bought this printer at Costco, I took it back and got a refund. Then I bought a 6000 series HP printer. Works fine and no problems with power save.
Interestingly enough, Costco is still selling the 4500 printers!!! Go figure. Maybe the firmware is up to date...don't know and I didn't want to take a chance on it.
Get rid of the printer ... more trouble than it's worth.

Just spent 45 minutes with HP support. They're sending a replacement (refurbished) printer. They say the current 4500's have new firmware and that the "Power Save Mode" problem has been resolved. If I had realized I could return it to Costco I would have. HP was nice, but 45 minutes is 45 minutes.
