CM1415fnw Crashes While Faxing

[OutOfTheBox]

This machine has the nasty habit of initializing (read crashing) at seemingly random intervals when faxing out.  It is a crap shoot as to whether it will do this or not every time that a person faxes.  It is used in an office environment of primarily Windows XP machines, but does not initialize when printing or scanning.  I have installed and reinstalled the current firmware patch several times, so please don't waste my time or yours suggesting that.  I have also reset to factory defaults several times, changed where it was plugged in using an extension cord, changed the port on the switch that it is connected to to try to resolve this problem.  In the Error Log for the machine it says code '49.0039'.  In the Fax Send Log it says 'Power Fail'.  I know from experience with the 1536dnf that this replaced that, unless all of these machines have faulty parts (I went through three replacements from HP that all had the same problem) that this is unlikely to be a hardware issue.  Does somebody know of a solution to this problem?  As a programmer myself, if I programmed something to crash when It thought that there was line noise I would not keep my job for long.  I keeping hoping against hope that someone out there wil have a solution, or that HP will actually listen and put out a firmware patch to solve this problem.  Sorry for my rant, but please, please help if you can.

I see that you previously had two 1536dnf that experienced this (googled the error, I'm not an HP employee). Laserjet's really do use a ton of juice, we've got 30 of them here and all are on dedicated circuits. You might want to look at the amount of power it's getting. Initializing the scanner bulb causes spikes that lead to seemingly different issues (one of ours spit out all the paper everytime the bulb came on).

That kind of thing is why I mentioned the extension cord.  I actually ran the cord to another group of sockets where nothing else was plugged in.  It still initialized whenever it felt like.  Thank you, though for your response.  I have, though, made several page scans to PDF using the feeder, not as much as people fax out, but maybe a couple of dozen times in the past couple of months, and I have never gotten it to initialize.  It only seems to happen and then only some of the times that people fax out.  I never had this problem with a cheap Canon all-in-one that the 1536, and now this, replaced.
