This does make me wonder how many people have thrown away an otherwise functional printer, just because this roller and tension spring design isn't fit for purpose. Sometimes the stupidly simple solutions are the best! So thanks, David Camm, wherever you may be - you solved my frustrations and prevented me taking apart my printer in desperation to try and fix.
An old Dishmatic head was just the right dimensions and with enough pushback thanks to the top layer to give the rollers adequate friction. I realised that, as long as you fitted correctly-sized pieces of sponge snugly, and underneath the part of the bar closest to the tray slide rail (and without it catching in the rotating arm which drives the rollers), this is a beautifully neat solution which solves the problem.

Make sure the plastic holding the roller still moves up and down freely, the sponge should not be so tight as it prevents free movement.My MG550 had this issue from new as well but this spong has fixed it. just done 150 double sided sheets with no problems. This increases pressure on the roller so it takes the paper every time. Put the sponge behind the piece of plastic away from the rollers taking care not to put it behind the actual rollers. I noticed there is hardly any force pressing the roller to the paper, hence the problem. You will notice the feeder roller attached to a plastic panel that moves up and down to grip the paper, this roller has a small spring on the side. (its under the printer behind a panel that has the paper in. Now find the paper feeder roller that takes the paper from the tray. Hi Folks, this is an asy fix, get a sponge, I used the sponge off a dish scourer, you only need half of that, cut it off the scourer part. I wanted to avoid removing the tiny tension spring, because they frequently fly off into another dimension, and fortunately I stumbled upon a post by David Camm on a TechAdvisor forum thread: So I went to the Internet for inspiration because I knew I wanted to somehow either add weight to the horizontal bar on which the rollers were mounted, or increase the spring tension. There's nothing really you can adjust with these printers the tension spring was just not good enough to adequately pull the rollers down into contact with the paper. You end up stretching the rubber tracks around the feed rollers, wearing them smooth prematurely and ending up with catastrophic loss of grip, just like excessive camber on F1 cars (ha). I tried all sorts - wrapping the rollers with small strips of tacky gaffertape to widen their diameter, pushing up on the underside of the paper tray to try and make them contact the rollers better, even moving the rubber tracks towards the edge of the wheels to make their edges 'ride up' and contact the paper better.īut in the end, some sponge (visible behind the bar supporting the feed rollers) solved the problem! ( view larger)īefore I used the sponge method, moving the grippy rubber bands to the edge of the grooves on the rollers worked, proving it was a simple issue of roller clearance, but it's not ideal.

I have a cheap Canon Pixma MG5750, a Currys PC World purchase when I needed a cheap multifunction printer fast.
