I dont think there is a way to see how much toner there is left.

A good indication of when the toner needs replacing is when text is light in
areas.

Another good way is to keep a record of how many pages have been printed
since first installing a new toner by accessing the service mode.

1. Hold down the [On Line], [Form Feed], and [Enter] keys while powering ON
the printer, until the ON LINE and FORM FEED indicators are both illuminated
and the Display Window is blank. (If the Display Window reads 05 SELF TEST
at this point, the keys were released too soon. Repeat this step until
successful.)
2. Press the [Form Feed] key, then the [Enter] key. The message SERVICE MODE
is displayed briefly, then the printer automatically begins a 05 SELF TEST.
After several seconds, the ON LINE and FORM FEED lights turn OFF.
(The printer may display 02 WARMING UP if it has not warmed up completely.)
After the printer has warmed up and passed the self test, SERVICE MODE is
displayed.
3. Press [Menus] once to display SERVICE MENU.
4. Once it says SERVICE MENU press ITEM to scroll through service mode
items.

PAGES=XXXXXX represents how many pages has been printed in total. Make a
note of this number when you insert a new toner cartridge and then compare
the approximate amount estimated of pages that can be printed from a new
toner to the total on the screen. (Take the original number that you made a
note of from the new number that is displayed).

5. To exit the Service Mode press the [On Line] key.

It's only a rough method but it's better than nothing.

Also I think there is HP management software that can be downloaded. I
think that also can keep a page count for you.

Cheers Peter, this method will work a treat once I install a new toner
(after this one has finished of course!).

It seems it's had 100,000 page prints in total...


Regards,
Matt

You're welcome.

A 100,000 page count is quite low for a HP LJ 4, they really are little work
horses. I have serviced others that have a much higher page count than that
and still churn out pages of good quality. If you look after it and carry
out regular maintenance it will last for ages.
