Hi Daniel, the P1000 series formatter has not been available at HP since 2013, you can try to get scrap or you have a complete machine in the market for $ 950 little more than any scrap formatter.
To locate the spare parts and if they are available enter:
http://partsurfer.hp.com/Search.aspx?IsmobileDevice=Y
select the country and then search by model for example for your printer could be:
CB410A, CB410AR, CB411A, CB411AR, CC365A, CC366A is the number on the silver label on the printer
I await your comment, best regards
