Designjet T795 CR649C
Microsoft Windows 10 (64-bit)

My T795 plotter will not get past 1%. The 2nd LED is flashing. I cannot update firware because it won't recognize the USB stick in either the front panel port or the usb port on the formatter on reboot. I reseated the formatter, replaced the 3v battery and rebooted several times. Don't know if the hard drive is bad or the formatter board is bad or both.

I replaced the hard drive and installed new firmware. The plotter has been working ok since.

It depends on the LED lights on formatter too , and you should check which one is off and which one is on and which one is blinking , and then you can find out which part needs to be replaced , HDD ,Formatter, Main PCA and Power Supply
