Not an expert on this brand of printers but it looks like dirty feeder rollers to me. Try cleaning them and Print a Blank document and see if the marks show up

Sir/Madam

If your printed pages have a horizontal line in the text or graphics (as shown in the illustration below) or blank text, some of the nozzles may be clogged and need to be cleaned

Most all-in-ones require you to scan an alignment sheet after changing the ink. Make sure the printer is on. Press Menu then use the up and down arrows to navigate to Maintenance. Click OK. Navigate to Auto Head Align and press OK. Select Yes and press OK. Load a sheet of Letter or A4 sized plain white paper in the rear tray, follow the on-screen directions. Open the output tray gently and the output tray extension. Press OK. When the page prints out, do not touch the printed sections. You should see a set of broken lines on the page, among other printing. The first section of columns will have 2 black, 1 blue and 3 black. The next row has 4 columns (blue and pink (to my eye)); the final row is 3 blue and 3 pink. If this prints okay, then select Yes and press OK. Next place the printed page face down on the glass of the scanner unit so that the black triangle at the top left of the page is in the left back corner of the glass. (The triangle is an alignment mark and lines up with the alignment mark on the edge of the scanner unit.) Close the document cover and press OK. The sheet will be scanned and the print heads will be adjusted. Do not open the document cover or move the sheet until the unit has completed the adjustment. Afterwards you can discard the sheet.

If the unit fails to adjust the print head, it will indicate this in the LCD screen. In that case, try manually adjusting the print head from the Canon Toolbox on your computer. If you can't get the printhead to align properly manually, the unit may need service.

For pictures, see the manual or support for the all-in-one here: http://www.usa.canon.com/cusa/consumer/products/printers_multifunction/photo_all_in_one_inkjet_printers/pixma_mp490#ServiceAndSupport . If you use the Support option, search for align print head.

I hope this helps.

If it's a spotty line, that most likely points to the fuser. Maybe something tore the belt or scratched the roller in there.

How to improve print quality Cleaning the print head
To ensure good print quality, the MFC will regularly clean the print head. You can start the cleaning process manually if needed. Clean the print head and ink cartridges if you get a horizontal line in the text or graphics on your printed pages. You can clean Black only or three colors at a time (Cyan/Yellow/Magenta), or all four colors at once.
Cleaning the print head consumes ink. Cleaning too often uses ink unnecessarily.
Caution
Do NOT touch the print head. Touching the print head may cause permanent damage and may void the print head’s warranty.

2 Press ▲ or ▼ to select Cleaning.
Press Menu/Set.
3 Press ▲ or ▼ to select Black, Color or All.
Press Menu/Set.
The MFC will clean the print head. When cleaning is finished, the MFC will go back to standby mode automatically. If you clean the print head at least five times and the print has not improved, call Brother Customer Service (see Brother numbers on page i).

Yes this could be the drum.

You could remove the drum and carefully look for the pattern of dots etc that you are getting on the page but on the drum surface.

I would suggest replacing the drum 1st and retrying.

If the black lines are just down one edge then the fuser could be to blame for the black marks but without being able to see the page i cant tell. The drum is certainly my 1st suspect and is easy for you to try.
