Bill,
This is an off the wall conjecture based on the assumption that you are using the Epson Clara dye based inks and not a pigmented ink in your printer.  Could it be possible that the inks are old and have begun to deteriorate a little, that the some of print head nozzles might be dirty or clogged despite maintenance cleanings, or that either in the image editing software or the printer driver, the color intent setting has accidentally changed or is inappropriate.  While I suppose that the Spyder could be out of spec, it seems to me that the problem lies more in the printing and the printer, its inking levels, and maybe even spray patterns.  However, as I said, this is just a conjecture on my part.  I do know that as dye based inks get older, they get darker.

Good luck in tracking down the cause.  I know it can be frustrating – to say the least.

Using Spyder 4.0.2, calibrating the monitor to 121 cd/m^2 (and yes, I got the number right this time), my prints from an Epson 1430 printer are still too dark, compared to the monitor. This is consistent across three printer profiles - the canned Epson profile for Premium Luster, my own profile made with a SpyderPRINT package, and a custom profile I had made by Michael Gordon of "GreatPrinterProfiles". 



Color management is correct. The targets for the custom printer profile was printed with Adobe Custom Printer Utility, which turns off all color management. The other prints were made with the correct paper selected and with ICM checked as "OFF" in printer properties.



Is it possible that my Spyder calibrating tool is out of spec? Is there any way I can check this myself?
