[BBLISA] HP plotter repair

[Bob Gill]

Greetings:

The short question - does anyone know of a company besides HP that will 
service HP plotters?

The detail...  we have a HP DesignJet 800 plotter with a "System error 
21:10 - Call HP Support" message lodged in it's craw.  Everything I find 
online indicates that what needs to be replaced is something called the 
"service station" which appears to sell for ~$110 on HP's parts site.  

For the privilege of not getting my hands dirty (and fixing anything 
else that might be wrong if it isn't the service station) HP wants 
$1530.  Nice mark-up.

I really don't want to work on this thing myself however I can't in good 
conscience ask the company to pay $1.5k for my convenience.

Any info you have to share would be appreciated.

Thanks,
Bob Gill
