REPLACEMENT PROCEDURES

This chapter provides in-depth instruction on all primary component and assembly replacement, in addition to most secondary components. Use the text in conjunction with their accompanied graphics to ensure complete comprehension throughout the process. Especially observe all cautionary or warning notations.

CAUTION: STATIC ELECTRICITY CAN RESULT IN COMPONENT DAMAGE.

OBSERVE APPROPRIATE GROUNDING PROCEDURES WHEN REPLACING ANY

COMPONENTS.

PRINT HEAD REPLACEMENT

If the print head becomes damaged or worn, it can be easily removed and replaced without having to make critical adjustments. Before replacing the print head, check the head counter values by printing a test pattern. Instructions relating to the Head Counter may be found in the Configuration unit of this manual.

1.Switch off the printer, disconnect power supply cord, and remove media/ribbon.

2.Open the right housing cover and latch print head release lever (1, Figure 6-1a) as necessary.

3.Remove screw (2) from upper print assembly (3) securing defective print head (4, Figure 6-1b).

4.Unlatch print head release lever (1) and withdraw defective print head (4) from within print assembly (3).

5.Disconnect the two wiring harnesses (not shown) from defective print head (4).

6.Reconnect two wiring harnesses (not shown) to replacement print head (4).

NOTE: Each of the printer’s wiring harness connectors are different from all others to ensure proper mating. Mate each matching half for reconnection.

7.Insert replacement print head (4) into print assembly (3) and latch lever (1, Figure 6-1a).

CAUTION: EXCERCIZE CARE WHEN INSTALLING THE PRINT HEAD TO

ENSURE THAT ITS ELEMENTS ARE NOT DAMAGED DURING INSTALLATION.
