Featuring a modular arrangement of technical reference materials, the manual documents General Description and Specifications sections that establish the baseline for PC-D320, PC-D340, and FAX-L400 systems. The document provides Technical Reference content covering component layout, scanner section architecture, paper supply section structure, and printer section operation, while Assembly and Disassembly chapters address document feed configuration, recording section procedures, and fixing section maintenance.

Removal procedures are documented for separation roller assemblies, separation guide units, and document feed roller components across both PC-D340/FAX-L400 and PC-D320 variants. Technical specifications are provided for general operation parameters including voltage requirements (AC 220–240V at 50Hz), power consumption ranges (standby modes from 5–11W, operational modes up to 670W maximum), and environmental operating conditions (10–32.5°C ambient temperature with 20–80% relative humidity tolerance).

Factory specifications are documented for communication protocols including ITU-T V.8 and V.34 standards, G3 facsimile transmission methods with multiple modulation schemes (V.27ter, V.29, V.17, and V.34), and scanning resolution specifications ranging from standard through ultrafine densities. Engine rebuild procedures are documented for laser/scanner section components including the 4-faced polygon mirror, scanner motor operation, and BD sensor malfunction detection parameters.

Drivetrain specifications are addressed in the paper supply and feed sections, covering pick-up solenoid operation, main motor control, recording paper jam detection configuration with sensor timing intervals, and delivery system operation across cassette and multi-purpose tray implementations. The manual documents torque specifications for bearing preload accuracy across mechanical assemblies to ensure proper component engagement and system reliability.

Maintenance and Service chapter includes comprehensive cleaning procedures for platen glass, contact sensor surfaces, transfer charging roller, fixing film unit, and pressure roller components. Troubleshooting Index sections reference error codes and user error messages with systematic resolution procedures, while Service Switches documentation addresses both hardware switches (jumper configuration on SCNT board, test print switch on ECNT board) and service data settings across multiple menu structures.

FAQ

What are the **proper** clearance measurements for fixing pressure roller adjustment? keyboard_arrow_down

6.0 mm to 7.6 mm represents the required center nip width specification, with right and left margins maintaining equal 6.0 to 7.6 mm dimensions for optimal print quality and fixing performance.

Specify the **standard** grease part numbers required for machine lubrication. keyboard_arrow_down

HY9-0007 (MOLYKOTE EM-50L), HY9-0023 (MOLYKOTE EMD-110), CK-0562 (MOLYKOTE PG-641), CK-8006 (IF-20), and CK-8007 (MOLYKOTE 41) are the approved lubricants for specified components throughout the system.

What is the **necessary** safety precaution when disassembling high-temperature components? keyboard_arrow_down

10 minutes minimum cool-down time after power shutdown is required to prevent burns during disassembly, particularly for motors, power supply units, heatsink-equipped ICs, and fixing unit covers.

Calculate the **recommended** D-RAM memory capacity for image storage. keyboard_arrow_down

13824 kilobytes total D-RAM capacity is allocated for image data backup and document memory reception according to system specifications documented in the service data configuration.
