OEM Lexmark 18C0032 (#32) Black Ink Cartridge.
LEXMARK 7100 Works Great With LD Product
I have a Lexmark 7100. Because I had another printer where i used substitute cartridges that went bad, i decided that i would
use OEM cartridges and the results have been great.
The one big factor that convinced me to use OEM was the longer
shelf life of the cartridges for the Lexmark.
