Epson Stylus pro 4800 inkjet printer error codes

Recently I had a "Service Req." message come up on my 4800. There have also been a few questions on Forums about what various error messages mean, so I thought I would post a listing that I have for the Epson 4800. This is not an official Epson listing, but it appears to be accurate in the few cases that I have had to use it

Firstly please excuse the lack of formating of the listings below, but it would take me too long to put it into pristine formatted text and it would never arrive - I think anyone looking for the info should be able to find it here.

There are two types of error codes. Those indicating a maintenance issue that can usually be sorted out by resetting a counter or checking something is still OK after its nominal end of life. The second set are service errors that may need a technician to fix them, although many of them seem to respond to a certain amount of informed and sensible "fiddling" about; in some the descriptions indicate the action that should be taken to resolve the problem.
