I have been away from my printer for a number of weeks due to the Xmas holidays, and got a nasty surprise when I returned... The Cetus software does not even recognize the existance of the printer, even via USB.
电脑识别USB连接的哔哔声hen the printer gets plugged in, but no comms.
I powered up the Cetus with the cover off to look at the LEDs on the Daughterboard. I'm getting solid red LED for power and blinking red LED for SYS, but nothing for LINK, TX1 or RX1. On the motherboard, I have a green LED at Dp1.
The motherboard is a replacement, and had run for a solid month or so before the shutdown. Since then it has been powered off and disconnected fomthe USB.
I know there is another thread on USB failure, but I see no signs of trauma on any of the resistors.
Any ideas? I'm getting weary of paying Tiertime for replacement motherboards.
