Having a issue of section of steps hitting comb plates in down direction, I'll have 5 steps hit then another section of about 3 or 4 steps hit comb plates on impact plate?
Cheked carriage tension OK checked rollers OK checked demarcation treads on steps ok. What am I missing.
Like I said it only hits 5 steps and then a couple steps go by then another 3 or 4 steps hit. All other steps are fine coming in to comb impact.
