1.HP OfficeJet 7310xi does not shut off, scanner light alway on

The printer is supposed to go into a power save mode after a 
configurable time. I configured mine for 1 hour. It didn't work. The 
printer stayed on all the time. What is worse, the scanner light stayed 
on all the time.

I am convinced that this is a firmware problem. My first printer 
(firmware revision RL3001xNx) exhibited this problem but my second 
(RL4001xNx) did not.

My first printer would also get into a state where I could not turn it 
off from the front panel. I would have to yank the power cable from the 
back to get it to turn off.

HP tech support says that this is not a problem. They say that it is 
designed to leave the scanner light on all the time. Huh? Are you 
kidding me?

Of course, by the time the bulb burns out the printer will be out of 
warranty and it won't be an HP problem then - it will be your problem. 
They should say that this is not an HP problem.

I am sure that the HP company line forces the tech support people not to 
admit this problem because they would have a huge problem if everyone 
returned their printer like I did. I don't know if I should believe them 
but they tell me that the only way to upgrade the firmware is for the 
factory to do it. I see no firmware upgrades on the web. Since they gave 
me no alternative, I returned the printer to my vendor and picked up a 
new one.

I was lucky. The printer I got in exchange for the old one had newer 
firmware that fixed the problem. It also fixed some other problems I was 
having.

2.Kayak XAs 7/500 MT: switch off the I/O fan warning light

Hi,

I've got 3 dual-CPU Kayak's and like them (those are my first dual-CPU
PCs ever and I run OpenBSD on them). However from the one of them
I had to remove the fan and the speaker at the very bottom (facing
front).

Now the small BW LCD-display which should normally show a smiley,
shows the warning about a failed I/O fan and a nearby red light is
blinking.

Is there a way to switch this warning off, as I don't really need that
fan?

I've found nothing in the PhoenixBIOS (which I've up'ed to HU 11.11 US)

Thank you
Alex

4.LJ6L light stays on and printer does not print

LJ6L printer 4+ year old.  Error light stays on.

It worked until yesterday.  When it was printing several pages, it 
stopped printing midpage.  I opened it and pulled the paper out (and it 
came out whole).  Now the yellow error light is constantly on (not 
blinking).
 
There is no paper stuck in the printer.  The toner cartridge looks 
fine.  I press the little button on front and wait for the 3 lights to 
come on in sequence; it goes thru the sequence but always ends up with 
the error light on, and the printer will not print at all.  I unplugged 
the printer for 10 minutes and disconnected it from the PC.  No change.

Any ideas what I could try?

Thanks!

Joel
