uploading new firmware error

I am getting 
Arduino: 1.8.2 (Windows 10), Board: "Arduino/Genuino Mega or Mega 2560, ATmega2560 (Mega 2560)"

Sketch uses 132554 bytes (52%) of program storage space. Maximum is 253952 bytes.
Global variables use 6922 bytes (84%) of dynamic memory, leaving 1270 bytes for local variables. Maximum is 8192 bytes.
Low memory available, stability problems may occur.
avrdude: verification error, first mismatch at byte 0x17e00
         0x00 != 0x1e
avrdude: verification error; content mismatch
avrdude: verification error; content mismatch

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

    Just retry. Comparison showed a wrong value in flash so software on board is defect if that part is used. Often this is just coming from a communication error and after a reupload it will vanish or be another address will be wrong if communication is error prone. In that case try a better usb cable or uploading with main power of printer off.
