2009 Kyocera FS-C5300DN, FS-C5200DN, and FS-C5100DN Printer Service Manual (P/N 2HNSM062)

This Kyocera Mita service manual, 2HNSM062, Rev. 2 (December 2009), covers the FS-C5300DN, FS-C5200DN, and FS-C5100DN color laser printers.

• Paper feed and duplex repair: Illustrated removal and refitting of the paper feed roller assembly, retard roller, MP paper feed roller, and duplex unit B.

• Imaging and transfer: Replacement procedures for the developing unit, drum unit, main charger unit, intermediate transfer unit, and transfer roller unit.

• Fuser and laser scanner service: Fuser unit and laser scanner unit removal, with component layout drawings and related fault checks.

• Electrical diagnosis: Self-diagnostic code tables, electrical fault checks, and replacement procedures for the power source PWB, main PWB, engine PWB, and high voltage PWB.

• Service modes: Service and network status reports, event logs, developer refreshing, LSU dust shield glass and main charger cleaning, drum refreshing, and maintenance kit counter resets.

• Firmware and circuit references: USB and CompactFlash update procedures, wiring diagrams, PWB silk-screen diagrams, and connector signal tables.

This manual is suited to printer service technicians familiar with continuity checks, circuit-board handling, and internal component replacement.

Print Quality and Paper-Path Diagnosis

The troubleshooting chapters map self-diagnostic codes to detection conditions, likely causes, and corrective checks. Image formation charts cover light output, vertical and horizontal streaks, spots, loose fusing, and color offset.

Comparing repeated marks with the repetitive defects gauge helps narrow the fault to a drum or roller before selecting replacement parts. Service status pages and event logs document operating history, fault occurrences, and maintenance records.

Paper-jam logs identify the feed source and jam location. For several optional paper feeder repairs, the troubleshooting tables refer to a separate feeder service manual.

Color calibration and manual color-registration procedures are referred to the operation guide.

Component Repair and Board References

Detailed assembly drawings show access through the outer covers and identify cassette-dependent paper feed parts. Ozone filter replacement, waste toner box removal, and waste toner full sensor diagnosis extend the maintenance coverage.

Regional maintenance parts lists distinguish MK-550 and MK-560 kits, including the FK-560(U) and FK-560(E) fuser assemblies.

The engine PWB replacement section covers EEPROM U4 transfer. It also explains how over-inserting the assembly can deform the board plate and disrupt the ID sensor cleaning system.

Machine cross section views and the paper conveying section block diagram show the paper path and its electrical connections. The main charger unit block diagram identifies the wire, grid, and high-voltage connections.

The engine PWB silk-screen diagram and wiring diagrams support circuit tracing alongside connector, pin, signal, and voltage tables. Fuser fault entries specify thermistor detection conditions.

Follow the manual's electrical-isolation precautions before disassembly; charger circuits and fuser components involve high voltage and hot surfaces.

Firmware and Optional Hardware

The firmware chapter covers engine and system updates from USB memory or CompactFlash. F010 controller recovery requires CompactFlash; USB memory is not usable for that procedure.

The installation chapter covers site requirements, expansion memory, and memory cards; hard disk installation applies only to the 2HN variant. The installation cautions explain how inserting or removing expansion memory while powered can damage both the printer and the module.

Examples of Roller Spacing and Sensor Signals

These examples are a small selection of the manual's image-defect and electrical reference data.

In the repetitive defects gauge, the heat-roller repeat interval is 82 mm for product code 2HN and 98 mm for 2HM and 2HL.

For the registration sensor, the engine PWB table lists REGPAP at connector YC7, pin 3, as a 0/3.3 V DC On/Off signal.

Searchable Service Text and PDF Contents

Search, bookmarks, and diagram detail: The service chapters have searchable text and embedded PDF bookmarks. Small connector and signal labels in the sideways wiring diagrams need zooming and page rotation for comfortable reading. The two manufacturer contact pages do not support text search.

Supplied as one printable 188-page PDF in English. The total includes 164 pages of technical content, 11 preliminary pages covering the title page, revision history, safety information, and contents, 11 intentionally blank pages, and two manufacturer contact pages.
