Hi, I'm Ashik. Welcome to JustAnswer. I'm reviewing your question now, and will post back with your reply ASAP
Are you using an Apple Mac or Windows PC ?
Thanks for the info. To do copies without computer, all you have to do is, load the paper, put the document on the scanner and click the Black or Color button once. This will make a copy instantly. Let me know if this is not working.
To scan to your computer, follow the steps below;
Step 1 :
First download and install latest drivers for your printer, on your computer from here --> http://www.canon-europe.com/support/consumer_products/products/fax__multifunctionals/inkjet/pixma_mg_series/pixma_mg2940.aspx?type=drivers&language=EN&os=Windows%2010%20(64-bit)
Download the -- > MG2900 series Full Driver & Software Package (Windows 10/10 x64/8.1/8.1 x64/8/8 x64/7/7 x64/Vista/Vista64/XP)
After downloading the driver, open it and follow the onscreen instructions. This will install latest printer and scanner drivers and software. You can ignore this step if you already installed the printer on your computer using the disc came with it.
Step 2 :
You will see Canon Scan or Canon application on your computer's start menu. Open it and follow the instructions to scan.
You can also use Windows' Scan app to scan. Click on Start and select Scan app (you can search Scan on the searchbox at bottom left to find it easily). Open it and it will allow you to scan.
The scanned files will be stored on your Pictures or Documents folder.
If you have any difficulty on following the steps above, please let me know and I will continue to help you
