new printer or not?

[viccar1]

I have a Ricoh 3310 A4 running sublijet R,

I need 3 new inks and a new waste ink bit, keep having paper jams, this machine has done me well for 6 years.

What is the latest version and ink, i always liked the ricoh its easy to use and rarely goes wrong.

Just wondering if to get a new printer and inks or stay the same and try to fix the paper feed.

Must run on windows 7
