[PrintOwners] Weight of HP 45 ink cartridges?

[Steve Blatman]

Dick & Michael,

Thanks for the information. We put the partials in Tupperware with a 
moist paper towel or piece of a rag. I hadn't thought of covering the 
business end of the cartridge with a rubber band, but I think we'll 
start doing that.

The reason I wanted to know the weight of an empty cartridge (either 
by knowing the amount of liquid inside, drilling and emptying, or 
whatever) was so I'd know whether a cartridge was clogged or empty 
when it wasn't printing well.

So, if a full cartridge weighs 4.06 oz., and it contains 42 ml of a 
liquid with about the same density as water, an empty cartridge 
should weigh about 42 grams less than a full one, or about 2.58 oz.

Thanks,
Steve
