20 I believe it depends on the manufacturer (surprise surprise).
22 My HP counts "pages from new" until it's used 10%, then when it gets to
23 ten times that it throws up a WARNING that the cartridge is empty and
24 needs replacing. But it doesn't stop printing (and I think that last is
25 true for all HPs).
27 So we've had cartridges just keep going and going, because it got used
28 for a bunch of photos when new, then just colour documents, and it's
29 been moaning "empty" for over half the cartridge's life.
31 Other manufacturers do stop when they think the cartridge is empty "to
32 protect the printer".
34 But HP has (afaik) always put the more consumable stuff into the
35 cartridge, so if you "abuse" it beyond end-of-life the printer itself is
36 unaffected. Other manufacturers (eg Brother) split consumables out into
37 replaceable items (like the toner belt).
39 Oh - and when our cartridges look like they're empty, I always give them
40 a shake because that often knocks toner out of the nooks and crannies
41 into the usable path, but it's a big warning that the cartridge does
42 need replacing ...
44 Cheers,
