Unit 6: Maintenance 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. To replace the print head, press inward on the release lever, retract and disconnect the damaged print head, connect the printer's wiring harnesses to the replacement print head, and insert upward into the upper print assembly. The properly installed print head will snap into position. CAUTION: EXCERCIZE CARE WHEN INSTALLING THE PRINT HEAD TO ENSURE THAT ITS ELEMENTS ARE NOT DAMAGED DURING INSTALLATION.
