Greetings ,
Yes. Both cartridges must be installed. The printer will not function with a single cartridge.

Thanks for joining the conversation, Billyboy1!
In order to give you the right information, we need to know exactly which printer model you're using. We checked just about everywhere and we couldn't find a printer with the model number you mentioned, so would you mind double-checking that? The model number should appear somewhere on the top or the front of your printer. That, and any other details you'd like to give will help the Community better understand your issue!
If this is a time-sensitive matter, click HERE search our knowledge base or find additional support options HERE.
Thanks and have a great day!
