Document Content Overview

The 2002 Sharp AR-122E/152E/153E/157E service manual contains technical documentation covering general product specifications, internal components, and maintenance routines. It details the digital laser copy process, including charging, exposure, developing, transfer, and fusing stages, with functional diagrams mapping the print process and paper transport routes. The document structure progresses through external and internal views, installation procedures, and assembly/disassembly instructions for major sections like the high-voltage unit, optical assembly, and fuser module.

Additional chapters explain the simulation mode and trouble codes, providing a lookup for diagnostic error messages like U2, L1, or E7. The electrical section presents block diagrams and circuit descriptions for the MCU PWB, operation panel, power supply, and noise filter circuits, alongside a comprehensive list of what an OEM service publication covers regarding machine operation and calibration.

Technical Data Preview

Technical specifications document the fuser temperature ranges as 165–190°C, with a safety threshold of 240°C. The main charger grid bias voltage is specified at –390 ±20V in low mode and 580 ±12V in high mode. Developing bias voltage is documented at –400 ±8V. The drum photoconductor type is OPC (30mm diameter) with a service life of 25,000 copies. The scanner system uses three CCD sensors with a 600 dpi resolution.

Coolant system and power consumption values are listed for various modes, showing 300 Wh/H for average copying power on most models. Fusing resistor placement and laser unit composition are detailed to support accurate maintenance. The main motor control signals, including PWM and encoder feedback, are referenced in the electrical signal tables. This 131-page Sharp OEM service manual covers the 2002 AR-122E/152E/153E/157E digital laser copier, providing full technical, electrical, and operational specifications for the identified copier range.
