Print quality troubleshooting

[nickyminaj]

Hello,

I am new to 3d printing and am struggling with print quality. i get lines on only 1 side of my prints and cant seem to figure out what the problem is.it almost looks like its missing part of the layer but the the rest of the print looks very good. i checked bed level, flowrate etc. and even secured my printer to a table incase its vibration related but nothing works. i am using a prusa i3 clone. any suggestions of what ican try will be appreciated.

Any idea?

Please help.
Thanks!

I didn't find the right solution from the Internet.

Do the lines tend to appear on the side opposite from where your cooling fan blows? If so you may be able to correct a lot of this by using a better cooling fan nozzle. For example if you have an Anet A8 a semicircular fan nozzle (https://www.thingiverse.com/thing:1954001) may improve things a lot.
