Epson R800, 8.17 Drivers and 10.6.2 still not printing properly

Question

Hi,
I am also having problems even with the new 8.17 drivers.
I have been doing some testing and there are definite differences between how Leopard and Snow Leopard prints.
I have printed the TC9.18RGB iSis(A4) test chart (for building output profiles with Gretag Macbeth's ProfileMaker 5.0.8).
If I print this chart in 10.5.8 with 3.0.9 drivers from PS CS4 with no colour management selected in PS and with colour management disabled in the printer driver, the charts print as I would expect them to, with clear, distinct steps. I have seen this chart printed so many times, I just know how it should look.
However, if I print the same chart in 10.6.2 with colour management switched off in PS and 8.17 driver, the same chart looks dark, almost like they are only representing the 3/4 tones to shadow end.
I went ahead and built my profiles anyway from the odd-looking Snow Leopard charts, with the captured target data from the less-than-ideal charts and the shadow-end of the profile is screwed, getting a very greenish cast.
The one thing I have noticed is that in the 10.6.2 / 8.17 driver if you select No Colour Adjustment and click on the Advanced Colour Settings, it shows you the ColorSync Profile based upon your paper type - so I wonder if there is still some colour managing going on, which obviously you don't want when printing test charts.
Anyone else have any ideas?
Cheers,
Matthew

Matthew, I dont' have an answer for your problem but wonder if you can help me with mine. I also have an R800 but since installing SL cannot get it to work correctly.
Initially I could print from it but had no printer settings.
When the new driver was issued by Epson a few days ago I thought my problem was solved. Downloaded driver and attempted to install but ran into a peculiar problem. As you know the install starts, downloads several files and then gives you the option to quit or continue. Not knowing which files have been downloaded I selected continue. However, this scenario continues ad infinitum and the only way I can quit the program is to do a force quit. I mean like I can literally sit for any time period you want to name and the install continue as if it's in a loop.
I have since deleted all epson files contained in library and in sys.pref.
Second attempt to install resulted in what appeared to be a normal setup including printer settings but now the printer will not print. Message reads error:/library/printer/epson
I feel that there must be some epson files left behind from the first install attempt but I don't seem to find them.
I've contacted epson and the only reply I got from them was 'download driver and install'.
After that lengthy explanation I have two questions.
First one, when installing the downloaded file should I quit the setup when the first query to continue or quit occurs, if not when?
Second question, where else would you look to be sure all the epson files are deleted before attempting a second install.
Really appreciate any help.
