What I have done:
Cleaned crumb tray tracks
Cleaned crumb tray
Checked for levelness
Checked medium draftboard for warping
Held medium draftboard down by strong magnets
I thought I was doing things wrong. This problem started out of the box - I just haven’t dealt with issue. I have gotten around it by printing things in the middle, and doing a lot of sanding. This problem is not unique to the medium fiberboard and a lot of sanding. I have had similar issues with the plywoods.
In the below images I am showing the back side with the adhesive pulled off. Some of the squares came out easily. Some I punched out with reasonable pressure (there is slight fringing in the hole though). The non-punched out squares are not cut all the way through.
I am assuming that if all is good - I should lift the board and the squares should be left on the tray - or at least I should be able to pull of the adhesive and most of the squares would come off when I did.
I am also having alignment issues, but I haven’t done any test to show this (anecdotal at the point).
Not sure what to do next.
