The manual makes one mention of "powersave" mode, in relation to a possible scanning issue - the solution is "wait".
In the case of this unit, no amount of waiting solves the problem. The printer does not come out of power save no matter what button you press... the only solution is to pull the power cord. SO even if printing something to it is able to wake it up (and the user swears this doesn't work) you couldn't use it as a fax or copier before doing something mechanical and possibly forcible first. Doesn't strike me as ideal.
This machine does not appear to have upgradeable firmware, or is that just because it's such a new product?

Just missed an important fax call, couldn't get the machine out of power save without pulling the power cord. We have a 2nd line and an 'always on' fax, to not miss any important communications when we are not home. I'd appreciate information on disabling power save if there is no other fix. Sure would like to be able to count on the fax function.

Resets are not a permanent fix but it may buy you more time inbetween the lockouts.

Odd instructions those! Pull the power cable from the back of the printer, *and* from the wall, plug back into the wall & then the printer? What, is there going to be some residual charge in the cable, or does the power *cable* need to be reset by unplugging it from the wall?
Perhaps I inadvertently did carry out this procedure (well, sans the power cable reset!), because since I posted the question the user hasn't reported the problem and it has been more than 2 months, with the printer in more or less daily (and at least weekly) use. I don't recall all the things I did exactly, but removing the USB connection while the printer was down could have been one of them.
As always, thanks for the responses. Have a great week!

The reasoning, as I understood it, was that the fax modem needed to be drained of power. As long as the printer is plugged into the wall the printer is still pulling power and thus holding onto something in memory. Draining the power causes the printer to release that memory and reset itself.
This technique will work for me every now and then. Its not really a solution to anything but it does let you get your work done.

Sadly, it would appear those days are past. The OJ 4500 has been on the pricelist for must be a year now, support call centres know about it, and... nada. So sad, but I suppose everyone is making printers cheaper and cheaper and therefore crappier, and if problems like this crop up who has time to fix them? Too busy developing the next generation of disposable technology. "Sorree for you, chuck it & get a new one".

Cheers, mate, hope you find your solution.

So what's that other site all about, then. Have HP duplicated the support forums? The company is too damn big, it constantly looks like the left hand knoweth not what the right hand doeth.
