This surprises me because I saw the exact opposite advice somewhere not too long ago. Wish I could remember where. They suggested using wedge type rubber door stops to raise the front of the machine. This provides a better sight line into the area you're trying to see, and is supposed to relieve strain on your upper back. I found it inconvenient because the machine tended to slip off the door stops, but it did seem to make it more ergonomic for me, and I was planning to fasten the wedges down some way and try again. I guess my point is, if one way doesn't help, try another?
