1.4.8 Cleaning of Linear Scale/Encoder Head

Clean the linear scale and the encoder head every 3 months or after

the linear guide is lubricated to prevent the feeder carriage from mal-

functioning.

Cleaning Procedure

(1) Be sure to turn off the power breaker before cleaning work.

(2) Fold the head cleaning paper as follows.

Fig. 4A85

(3) Wet both surfaces of Sides A and B (head cleaning paper) adequately

with alcohol (absolute ethanol).

(4) Insert the head cleaning paper into the clearance beside the en-

coder head such that Side B (engaged between the upper and lower

claws of the scale holder) faces the encoder side.

(7) Follow Steps (2) through (6) again, using new head cleaning paper.

(8) After the cleaning, move the feeder carriage sideways and clean

the linear scale with a cotton swab soaked in alcohol (absolute etha-

nol).

(9) Power up the machine and perform “Reference Mark Detection Mode”

to check the feeder carriage movement.
