Re: LPRng: HP Color LJ 4500 blank pages
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 ~christoph On Wed, 5 Feb 2003, Dan Kirkpatrick wrote: Thank you... it does appear to be the printer some of the time since some configuration prints from the printer printed blanks as well.

LPRng: HP Color LJ 4500 blank pages
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.
