***You can NOT successfully refill the #36 / 36XL or #37 / 37XL cartrdiges UNLESS you have an "A" after the cartridge number***
This inkjet refill kit is compatible with the following Lexmark inkjet printers:
Lexmark X3650 / X4650 / X5650 / X6650 / X6675 / Z2420 Printers
Note: Lexmark offers for sale two different versions of the same cartridge: The regular version (36 & 37) is NOT refillable. It is the "Return" or "Rebate" cartridge you agree to return the empty cartridge to Lexmark. In return, Lexmark gives you a $5.00 discount off the cartridge. The "A" version (36A / 36XLA & 37A / 37XLA) can easily be refilled. However, the price of the cartridge is roughly $5.00 higher than the regular version, so most people unknowingly buy the regular version.
• 4 oz black ink

• Provides approx. 10 refills for #36A / 7 refills for #36XLA Black
