4.5.9 Check alignment
Use a good quality wire or string to check for alignment. The wire or string must be able to
withstand sufficient tension in order to eliminate any sag. Adjust shims so that all rolls of the A2
through to the R2 idlers are in line within ± 0.8 mm (1/32").

wire or string (for alignment)
Although the accepted tolerance for idler alignment is ± 0.8 mm (1/32"), the scale-mounted idler
should never be lower than the adjacent idlers. Establishing good idler alignment is the most
important part of the installation procedure. Scale accuracy is directly affected by alignment.
