Officejet 8600 Pro+ Power-switch lamp cycling bright then dim [ Edited ]

[PenSphere]

My Officejet 8600 Pro+ printer is brand new, and is connected via my wired network. It's working perfectly so far. Wi-Fi and fax are both (deliberately) turned off / disabled & not needed.

The Power-switch has a nice green light to indicate that the printer has "power" OK - and the lamp seems to have two "on" states, namely 'dim', and 'bright'.

The printer seems to go into "Sleep Mode" OK, and the control panel turns off as expected after my preset "Sleep" interval. (I'm not using the scheduling options.)  It also wakes-up OK when I send it a print job.  Again, everything is fine so far ...

While the printer is in this low-power 'ECO' state, the intensity of the green Power-switch lamp varies slowly between bright and dim, on a roughly 6-second cycle - 3 seconds at 'bright', then 3 seconds at 'dim', and it never stops cycling - bright then dim then bright etc..

BUT ... and here's my question ... should this lamp be staying 'dim' while the printer is asleep?
Or, does the fact that it is returning to 'bright' every few seconds imply that it is somehow failing to STAY fully 'asleep'?

I can't find any clues about this in the printer's manual.

Perhaps I should raise a query with the HP Support folks, but I thought I'd ask here first.

Thanks in anticipation.

Edited to add:
I'd be glad to know whether any other Officejet 8600 owner (or the owner of any other Officejet model) sees this same bright/dim behaviour on their Power-switch lamp?  Thanks.

Hi PenSphere,

This is by design. All the 8600 printers here at my location do the same thing. This is to let the customer know that the printer is in sleep mode and not turned off completely. I hope that helps answer your questions.

Thanks pcwizard,

I got the same reply yesterday from my HP Customer Care enquiry, and I'm satisfied now that my machine isn't cycling repeatedly into sleep mode and then 3 seconds later coming half "out" of sleep mode!

I know the HP design folks may never look at these Forum entries, but I'd hint to them that perhaps this ambiguous "sleep" indication might be made an optional choice, so that I could choose a steady low-intensity light instead.  It's not an enormous issue of course, but in my little "office" space, this Power button is right in my line-of-sight as I work, and - even though I now know that my printer is perfectly healthy - the slowly-pulsing light had become a recurring distraction until I covered it with a little 'disc' of semi-opaque sticky tape 

Thanks again.
