Finally finished all the cleaning. took the glass out, cleaned the double sided tape off with ipa 91%
cleaned the mirrors, didnt touch the lens tho. was to scared of breaking it.
still got the same problem.
I did notice that if I use VueScan it scans all the time albeit with the lines. But if I use Epson scan the preview always freezes and smudges the scan.
I did hear somewhere that a faulty power supply could cause these kind if issues but i dont want to buy a new one incase it doesnt fix the issue.
And Grat, Thanks for your reply. Im now thinking it a hardware fault too. alas being an unemployed single father of two. i just cant afford a new scanner at this present time.
