Maintenance and Technical Overview

This reference guide delivers clear technical insights into system configuration and maintenance scheduling for daily workshop use. It outlines periodic check requirements for user-replaceable units (CRU), such as toner and imaging cartridges. You will also find component-level breakdowns for the print control board, high-voltage unit, and the media feed driving system. A large section covers adjustment modes—including printer mode, utility mode, and soft switch settings—allowing you to accurately calibrate machine behavior on the bench or out in the field.

Specification and Diagnostic Data

Field support requires exact mechanical and electrical reference values. This manual lists them all. It includes system dimensions, operating noise levels (49–50 dB during printing), and North American power supply requirements (120 V AC, max 990 W). The guide highlights specific hardware differences, noting the 1690MF controller features 128 MB standard memory compared to the 64 MB in the 1680MF. Detailed jam display and sensor layout charts help technicians quickly isolate feed issues at the tray or fusing section.

Always ensure the machine is completely disconnected from power before inspecting internal components. Improper handling of the high-voltage unit or fusing section can result in severe electrical injury or burns. Precise fitment into the machine tabs is required during installation to ensure safe operation.
