I don't have the ArgyllCMS web pages open, but there is an option to either dispcal or dispread that invokes the DTP94 calibration mode--you must place the puck on a dark, preferably black, surface, so that all ambient light is excluded, and the instrument will go through some kind of self-test, the results of which are stored in the instrument. Perhaps that calibration data is missing, hence the error message. Pure speculation, of course. -----Original Message----- From: argyllcms-bounce@xxxxxxxxxxxxx [mailto:argyllcms-bounce@xxxxxxxxxxxxx] On Behalf Of Michael Karliner Sent: Tuesday, March 30, 2010 13:56 To: argyllcms@xxxxxxxxxxxxx Subject: [argyllcms] Lacie Blue Eye. Hi, I've just acquired a Lacie Blue Eye, which libusb recognises as a Monaco Optix, (vendor 0670 device 0001). When attempting to run dispcal, it just gives me the error message dispread: Error - new_dispread failed with 'Instrument Access Failed' running spotread gives me the error message Instrument initialisation failed with 'Hardward Failure' (CRT calibration values aren't set). I'd appreciate any clues as to what is wrong. I also realise that this is a pretty out of date piece of hardware, so it's possible that I'm just SOL, however the Monaco is listed as supported. Thanks in advance Mike K.
