CAUTION in the previous section and perform lubrication by strictly
following the steps specified.
1. Remove the printhead. (Refer to 4.2.7.1.)
2. Remove the carriage unit. (Refer to 4.2.7.10.)
3. Clean the carriage shaft by wiping the shaft's surface with a dry
cloth.

5. Using the dry cloth, completely wipe the inner surfaces of the 2
metallic bushings through which the carriage guide shaft is set.
Especially, wipe well off black stains if any. Also, clean the portion
where the pad was attached using the cloth.

6. Get a smallest-diameter syringe available. The small syringe shown
below only contains 2 cc maximally.
Be sure to use a small-diameter syringe to minimize
the tolerance. Small syringe allows you to see pushed
amount (stroke) more clearly.
