Epson 7800 Unused for 5 Years
Mike Sellers:
A friend in Arizona has a 7800 that hasn`t been used for over 5 years and he wants me to get it going. We are getting a new set of inks but what do I do if the heads are plugged up?

7800 is like that Ford/CHevy pick-up truck that just keeps running. Newer printers are more high tech and have more delicate parts. If you have difficulties---put warm water in the capping station and try parking the head on a windex or simple green soaked (folded) paper towel. Don't do that trick on the newer 79/9900/9890 series. You can also try some AIS or Inkjetmall solution in the capping station.

+1 to Ken's comments.
Once you get it all on line, I would do one power clean. This is run from the printer LCD and requires raising up the ink levers a few times Whole process takes about 15 minutes.
IF you do this and still have clogs, you can do at least one SSCL (Super Strong cleaning cycle) from the printer control panel, (this is run from your PC/Mac not the LCD of the printer). This process is even more involved but does get most clogs out.
Your biggest issue IMO will be the dampers, as there is no doubt old, and possibly dried up ink in there and as far as I know, no cleaning cycle will get there. However end user replacement of the dampers is not that hard on the 7800 family.
Lastly, make sure you check the wiper. With the power off (make sure it's off), release the head, and manually slide out of the way to the far left. Get a flashlight, and look up into where the head was parked. The wiper is a black rubber device running vertical towards to upper back. Get a swap, foam, with warm water and clean off the wiper. You might also consider a replacement wiper. They are cheap and again can be replaced with a little work. Not as easy as on a 9900, which has a process for it.

+1 for the Inkjetmall cleaning solution to keep the pad in the capping station moist.
My 9600 smiles when I drop a little bit of it on the foam pad.

Mike,
Before turning the machine on check the ink supply lines and dampers for pigment that may have settled or formed clumps, this will most likely be the case after such a long period of no use.
See this link to a previous post for an example of this issue.
As the other posters have said, also replace the dampers before running the machine and I would flush the ink lines and re-charge with new ink before sending any out of suspension pigment to the print head which will almost certainly cause print head channel clogging.
Good luck.
