The Business Inkjet 1100 has separate ink and printheads. If you run the
ink
out you can damage the printheads, which would then need to be replaced.
This cartridge (#10) is designed different than the #14, so the printhead
won't be dammaged by using a refilled cartridge even if the ink run totaly
out. The printer *knows* when the ink cartridge is empty, because in this
situation the pump works more frequent (the pump works to feed ink but when
the is no ink to feed the pump works continuously). When the printer "sees"
frequent activation of the pump, it knows that the ink cartridge is emtpy
and stop printing giving the "out of ink" message. This saves the
printheads.
The mentioned problem is dedicated only to HP printers that use the #14
cartridges, for those printers it's relly silly to refill the cartridges.
These cartridges don't have any mechanism to prevent printer printing when
the ink is run out.
As Andrew pointed out, the #10 ink supply has a memory on the cartridge rather
than the printer. No amount of swapping cartridges will make the printer
"forget" the ink level.
Older printers let you refill the cartridge once, but the ink level don't
work. I have heard that newer printers which use the #10 cartridge don't let
you consume the whole ink after you refill the cartridge, but I'm not sure
for that. Of course there is no other solution except from replacing the ink
cartridge. There are some chips, but I think they don't worth pricing.
