On the previous technical bulletin we mentioned the range of Lexmark return program cartridges that could not be filled. Going through the Lexmark website I have found a couple more cartridges:

Lexmark 41 (18Y0141A) & 42 (18Y0142A) are return program cartridges and are unable to be filled.

Recommend the following cartridges to your customer which can be refilled.
Lexmark 41A (18Y0341A) and 42A (18Y0342A)

The return program seems to be here to stay – so its important for everybody to keep up to date with what can and cannot be refilled!
