6.2.1 Lubricating the Carriage Guide Shaft
This section includes the procedure for lubricating the carriage guide
shaft. Unlike other models, the lubrication of the carriage guide shaft is
performed under many restrictions. Therefore, be sure to observe the
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.

4. Remove the Oil Pad (a felt pad) from the back of the carriage unit.
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.
