Used mimaki jv33-130 Improper shutdown before it was shipped

i recently bought a used mimaki jv33-130 from a company called omnicapital online. They said it was a lease that was returned. Said it was in working condition and I asked if it had been shutdown properly before being shipped to them and they said yes. I got the machine and there is still ink in the lines and dampers. I have not dealt with one of these in about 10 years, but that seems wrong. I just unpacked it and have done nothing to it besides remove the carriage cover. This machine was obviously not well taken care of in the past and I was told it has been sitting for about a month. The ink is not dry in the dampers and it is using es3 inks.
My question is if this machine is ruined and I was lied to about it’s condition? Should I return it? Should I turn it on and try doing anything to flush the lines? Please help me figure out my next steps. Thank you

 

I am returning it. The cost to fix it was more than I paid to get it. Thanks
