Lubrication 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 4.2.5)

2. Remove the carriage unit. (Refer to 4.2.6)

3. Clean the carriage shaft by wiping the shaft's surface with a dry cloth.

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.

4. Remove the Oil Pad (a felt pad) from the back of the carriage unit. NOTE: Donot re-use once removed pad.

5. Remove 2 springs securing sub-oil pads, and remove 2 sub-oil pad. NOTE: Donot re-use once removed sub-oil-pads.

4. Remove the Oil Pad (a felt pad) from the back of the carriage unit. NOTE: Donot re-use once removed pad.

5. Remove 2 springs securing sub-oil pads, and remove 2 sub-oil pad. NOTE: Donot re-use once removed sub-oil-pads.

Be sure to use a small-diameter syringe to minimize the tolerance. Small syringe allows you to see pushed amount (stroke) more clearly.

8. Get 2 new oil pads, and 2 new "sub oil pads".

9. To one of the new oil pads, supply ""O-12"" (0.5 cc) using the small syringe.

11. Install the other new oil pad to the specified position at the back of the carriage.

12. Install new sub oil pads to both bushing of the carriage, and re-attach 2 springs to secure 2 sub oil pads.

13. Using the same syringe used in Step 9, supply "O-12" (0.49 - 0.53 cc) to the installed oil pad.

14. Using the same syringe used in step 9, supply "O-12" (0.13 cc to 0.16 cc) to both new sub oil pads.

15. Install the carriage guide shaft to the carriage unit then to the printer main body. (See Chapter 4 / Section 4.2.6)

16. Install the printhead. (See Chapter 4 / Section 4.2.5)

17. Perform Paper Gap Adjustment. (See Chapter 5 / Section 5.2.9)

18. Turn the printer on without the ink cartridges installed to cause the Ink Cartridge Out Error.

19. Using the Load/Eject button, run the Ink Cartridge Replacement Sequence and install new ink cartridges.

20. Using the service program, perform Initial Ink Charge. (See Chapter 5 / Section 5.2.3)

21. Perform Head Angular Adjustment. (See Chapter 5 / Section 5.2.4)

22. Perform Bi-Directional Adjustment. (See Chapter 5 / Section 5.2.5)

23. Perform PF Adjustment. (See Chapter 5 / Section 5.2.6)
