Genuine OEM Ricoh GX3000SF Ink and Supplies

For the GX3000SF, GC21 means Ricoh ink cartridges, not laser toner. The four-color GC21 set combines the same black, cyan, magenta and yellow inks sold separately. It is a way to buy all four colors together, not a different type of cartridge.

Toner Buzz carries genuine Ricoh GC21 ink for the GX3000SF as individual cartridges and a four-color set. Choose an individual GC21 color for the ink you need, or the set for black and the three colors in one order.
