[GreenKeys] Tips for Securing Left Margin Adjustment on M15/19

[E.]

I would think - if you’re able to add a second nut to the screw and gently apply pressure against the first without stripping it, it would cause some torque against the threads, keeping the screw from turning — all in theory though :) .

I haven’t really had this problem with my 19 (the above), but one thing I did find was that if the basket return wheel was not tight enough, it would be slow to return the basket and at least the first character would be off because it would strike before the basket could fully return.  Just a random thought on this one though :) .

It seems the left margin adjustment screw (see attached images for visual of what I'm talking about) slowly adjusts itself out of alignment after so much use and eventually causes the carriage to get out of alignment on random CRs, causing one character to print before the margin on some lines.
