A:AnswerGood question. This laser printer takes HP 83A toner. The toner that comes in the box is a starter toner so it will be 40% full. A regular 83A toner yields up to 1500 pages.
I hope this helps!
A:AnswerHello, I see that you are interested in knowing how to install the black toner cartridge. Attached in a link to the owners manual for the Laserjet Pro MFP M127fn; http://h10032.www1.hp.com/ctg/Manual/c03628466.pdf
Hopefully that helps you out, and thanks again for choosing HP.
