HP Designjet T610 diagnosis

[za3atar]

I have recently purchased the HP designjet T610 it comes on off no problem almost wants to work before you know it is given me two codes 21:13 79:03 ,
Calling around for repair service as if I'm calling from a different planet , one guy told me we no longer work on HP,
HP no longer supply parts for them another says we have no technician to work on them , just about everyone have a different reason for not touching it , looks like I will be the only one who have to fix it , I have this bad habit and which everything that I take apart ends up in a bucket somewhere in the house so hopefully with your help I'll be able to have this issue resolved thank you and have a good day
