Instruction manual

– 5.10 –
Follow the procedure given below to replace the linear encoder PCB assy.
• After replacing the linear encoder PCB assy, be careful not to contact the linear en-
coder PCB scale. (Refer to the adjustment items.)
1) Remove the harness of the linear encoder PCB assy from the slider PCB.
2) Remove the screw (P3 x 8SMW) on the slider from the L-sensor BKT assy.
3) Remove the screw (P2 x 12), then remove the linear encoder PCB from the L-sensor BKT
assy., then replace it.
4) Pull the Y-timing long belt assy. from the Y bar and replace it.
Follow the procedure given below to replace the linear encoder PCB scale.
• After replacing the linear encoder PCB scale, be careful not to contact the linear
encoder PCB scale. (Refer to the adjustment items.)
1) Remove the YR cover and the YL cover.
2) Remove the screw (B3 x 6Ni), then remove the scale spring on on the left side of the Y
bar.
3) Remove the screw (B3 x 6Ni), then remove the linear encoder scale from the main unit,
then remove the scale hook and the scale holder L.
4) Replace the linear encoder scale.
[Assembling procedure]
• Assembly is reverse of disassembly.
