Hi Dan,
hmm, we don't have those anymore for quite a while and I never worked on
them myself :-( But I know that you have to push the menu button for quite
a while until the 'reset menu' appears. This had to be done after the
replacement of the ITB so maybe this will also rest the counter (?)
Did you try to reset the pagecount in the service mode ?
Someone else who runs HP4500s should know, come on guys !
cheers

Thank you... it does appear to be the printer some of the time since some
configuration prints from the printer printed blanks as well.
I've tried a cold reset and that didn't reset the drum life low
message. Now that I have a printout, it reports 67% left of transfer, 15%
left of drum.
So... Is there a way to reset the sensor on the drum and/or transfer kit?
or reset what the printer thinks? I dont see any resets on the readout
menus, or through the jet direct web interface.
I'm not sure what the hardware problem may be since there's still life left
on both pieces. Typically the first printout every morning results in
spewing blank pages until I turn it off. Turning it back on and resetting
the queue usually fixes it, but this morning I did that 5 times and still
printed blanks.
You mention So you can either reset the pagecount in the service menu or
reset the ITB unit: pull out the middle draw and the ITB (transfer belt) is
right in front of u.
I dont set anywhere to reset the pagecount in a service menu. And how do I
reset the ITB unit? I pulled it out and didn't see anything obvious to
reset other than cleaning the toner density sensor.
The service manual didn't provide any clues either.
Thanks so much!

Hi Dan,
I think this is a known hardware problem of the printer :-(
It thinks the ITB transfer kit needs to be replaced. The percentages
displayed are estimates from the formatter while the actual indication of
life over comes from a sensor on the ITB assembly itself. So you can
either reset the pagecount in the service menu or reset the ITB unit: pull
out the middle draw and the ITB (transfer belt) is right in front of u.
Maybe a cold reset would be fine also (hold the start button while
powering on the printer.
hope this helps

All of a sudden most of the time people print to a HP Color LJ4500DN, it
just keeps printing blank pages... the only way I can get it to work is
turn it off, turn it on, reset the queue, and maybe it prints then... just
to repeat again. LPRng and printcap entry havent changed, samba has
recently been upgraded, but am not sure if it coincides.
I've set the idle-timeout on the printer to 1200 sec to avoid the long
warmup problem, but that gets reset to 90 every time the printer gets
turned off.
They're printing through samba-2.2.7a-1 and LPRng-3.6.26-1
I'm not sure I understand all of the extra settings for waitend interval,
rw_timeout, socket linger...
Any suggestions?
Thanks!
Here's the printcap entry for the printer:
