PIXMA TS8150 scans only half the page

[Darshada]

Hello,

I have a PIXMA TS8150 printer and since earlier today, it won't scan correctly.

I was scanning 15 pages, the 3 first ones were going without any trouble and then suddenly it stopped working. It scans only half the page. I tried it both froml the panel and from my smartphone, trying auto-scan, document or photo, landscape or portrait. Still the same problem.
I checked on the internet. I tried to update the sofware (it is up-to-date), I cleaned the glass and I plugged in and out the power input.

Does someone have a solution here?

Thank you.

What does the Copy function do? 

Leave the platen cover up and watch as the lightbar moves.

Well, the light goes all the way without any trouble.

I called the support centre and they told me to re-install the printer program on the computer and it solved the problem.
