Canon pixma mp170 all in one printer

Are the cartridges in working order. I had similar problem with another make of printer when printer lights kept flashing and one of the cartridges was defective.

When the paper does not feed straight, dirty or stickyrollers can cause it to jamb or crinkle, also failure to remove all traces ofpaper from a previous paper jamb will cause further paper jambs.
Check for tiny pieces of at the edges of the rollers, and remove these piecesof paper. The rollers may be dirty or sticky and causes the paper tonot feed straight.
Try cleaning the rollers with methylated spirits.

Rollers need replacing. They are supposed to have tread like tires, if not, Replace.

Try cleaning the rollers again and fan the paper. When you clean the rollers, use alcohol and a lint free cloth. Don't put too many sheets in the feed tray.

Your feed rollers are either dirty or worn at some point. Try cleaning them with alcohol on a lint free cloth. Make sure you clean the entire circumference of the roller, or at least half of it.

hi,
use good quality paper for printing. clean the feed roller or get the printer serviced from the authorized dealer.
thanks

gears below the paper feeding tray are damaged or some dust particle have blocked the gears try to clean it by blowing the dust use normal greece (oily substance) between the gears so that they can move frequently to pull the paper, and if the gears are damaged you have to change the gears.

Yes I have the same problem :-( I have lots of work to do!!

There IS something stuck in the feed path. If the paper starts to feed and then crinkles on the feed side, there is an object stopping the paper moving forward.

Lay the machine on it's back and take a sheet of very stiff card (A5 size approx) and push it through the paper path in reverse. So start where the paper would normally exit and push the card in. You may need to lift the pinch rollers just behind the print head by hand to aid the card through. Keep the card to the side that would normally crinkle but beware of the paper sensor flag. If you force it you could break it off.

Once you get past the pinch rollers behind the print head, push a little further then start to move the card in and out but along the length of the rollers. You should find that sufficient to push out whatever is in the path and having the machine on it's back will help it fall clear of the feed mechanism.

If it does not fall out using this method you will have to remove the covers and try to remove the ASF to get at the object.
