Canon Lide 400 Uneven Lighting

[wanderaround21]

Hi there. I purchased the scanner last year and it has been working well till now. 

I noticed that some drawings that I scanned recently has some weird vertical light streaks on them. So I scanned a blank page and here's how it turned out.

 

So far I tried:
1, Cleaning the glass surface
2,  Turned on the calibration at every scan option  
3, Reinstall the IJ Scan Utility (i doubt that this even make it worse... the 1st blank page was scanned before I reinstall the software, the 2nd pic was from after that)
4, i tried using it on another computer, but the problem remained

And obviously, nothing worked. Is there any suggestion to fix this? Should I contact local canon service? 

Thank you in advance!
