Well is just had to bite the bullet and purchase a new printer. There were several problems that needed service with my 4800 and it wasn't worth repairing it, so I bought the 7890. It's an awesome printer, but a little bit of a learning curve is appearing. The other thing is that it loves to suck the ink to get set up, or clean nozzles or whatever it thinks it should be doing. It is not as easy to fool as my last printer with paper or sizes or anything and tomorrow I will start printing some cheesecloth skins, so I will learn how to use this printer with carrier sheets etc.
The color is beautiful and now I can print 24" wide which in the case of my new large book pages is a fabulous thing. This afternoon I am printing silk 17" wide prepared for printing. Think this is the last of my 17" fabric and then I will be precoating lutradur and heavy weight canvas to get my printer profiles down with those surfaces and also some recycled printers plates. Hopefully by the end of my planned printing I will feel a little more comfortable with this printer.
