Hi. I have a recently purchased Colormunki and I have used it a lot, due to a unsolved problem that I don't know if the reason is my inks, paper, printer drivers, me, etc., and I haven't received this message. After reading your email message I have read some patches very very slow and I cannot receive your "hardware error" message. The only error message that I receive sometimes is (too many patches) but the reason is that I started to read beeing the CM over a printed patched instead of a not printed zone. Also my firmware verssion is eactly the same as yours: Firmware version: 288 Chip ID: 01-ea1f0c150000a5 Version string: 'colormunki FW V1.32 Build Nr. 1303' Calibration Ver.: 6 I hope that it must help you to find the reason why you receive the error message. As Graeme Gill commmented you could be a HW issue as the USB port or a hardware error of your unit. Have you tested your unit on another USB port or on another computer?

Can anybody confirm this? If yes, this could possibly be considered a minor usability issue... Adding a message "Please try moving the instrument faster across the patches" could be very helpful :) If no, might this be due to the fact I'm still using an early firmware?: Firmware version: 288 Version string: 'colormunki FW V1.32 Build Nr. 1303' Regards, Pascal de Bruijn
