Kyocera Mita KM-1525 Parts List (P/N 842BV110, 842BV120)

• Four OEM PDFs, 581 pages total: the 190-page KM-1525 Service Manual, document code 842BV110 (March 2001); 44-page KM-1525 Parts List, 842BV120 (February 2001); 298-page KM-1530/KM-2030 Service Manual, 842AV110 (October 2000); and 49-page KM-1530/KM-2030 Parts List, 842AV120 (October 2000).
• Model-specific coverage separates the KM-1525 from the shared KM-1530/KM-2030 material, including regional electrical specifications, metric and inch controls, copier-speed configurations, and option differences.
• Factory repair procedures address paper feed, registration, scanner wires, laser scanner and ISU alignment, charging, drum, developing, transfer, cleaning, and fixing-unit work.
• Maintenance Mode and troubleshooting cover component tests, image and paper-path adjustments, self-diagnostic codes, misfeed logic, electrical failures, mechanical faults, and service counters.
• Electrical and firmware references provide PCB layouts, connector-signal data, timing charts, wiring and connection diagrams, machine-data backup and restoration, and model-specific firmware procedures.
• Thirty exploded parts sections supply indexed part numbers, regional quantities, service-part and subassembly symbols, model-specific assemblies, and illustrated fastener codes.

Model and Configuration Coverage

The set is divided by machine family, keeping parts and repair procedures tied to the correct copier. The KM-1525 service manual covers 220–240 V machines, while its parts list separates 230 V and 240 V quantities. The shared KM-1530/KM-2030 service manual covers 120 V and 220–240 V machines; its parts catalog provides separate 120 V, 230 V, and 240 V columns.

The KM-1530/KM-2030 material also distinguishes 15-cpm and 20-cpm control systems, metric and inch operation panels, model-specific cassette and deck hardware, and optional lower-drawer arrangements. It identifies duplex, job-separator, finisher, printer, fax, and network-scanner configurations as well. Coverage is organized by model and configuration; serial-number breakouts are not part of this set.

Service and Repair Procedures

Installation coverage includes unpacking, developer loading, initial copy-mode setup, copier-management settings, and test-copy checks. Option procedures address the KM-1525 total counter plus the key counter, original-size detection sensor, and drawer heater used with the KM-1530/KM-2030 family.

Paper-path repair covers removal and installation of upper, lower, and bypass feed pulleys, registration cleaner assemblies, and the bypass paper-width switch. Related adjustments include leading-edge registration, memory-image registration where applicable, image centerline, print margins, and paper slack.

Optical sections document the exposure lamp, scanner wires, laser scanner unit, and ISU. Adjustment procedures cover laser skew and vertical position, scanner squareness, main- and auxiliary-scan magnification, scan leading-edge registration, centerline, and contact-glass margins.

Image-formation work covers the charger assembly and tungsten wire, photoconductor drum, doctor blade, transfer roller, cleaning blade, drum separation claws, and lower cleaning seal. Fixing-unit procedures address the thermistor, separation claws, heater, heat roller, and press roller.

Diagnostics, Electrical Data, and Firmware

Maintenance Mode provides direct checks for motors, paper-path switches, clutches, solenoids, scanner travel, exposure-lamp operation, document-feeder functions, toner feed, and the fixing system. Its adjustment items cover scanner input and shading, automatic scanner setup, surface potential, developing bias and transfer output, developer initialization, toner-sensor control, print timing, and image margins.

Troubleshooting is organized around paper-misfeed conditions, self-diagnostic codes, image defects, electrical failures, and mechanical faults. Electrical chapters map PCBs, switches, sensors, motors, and other components, then explain the power-source, main, CCD, and laser-diode PCBs with connector-terminal voltage and signal tables.

The diagram package includes machine cross sections, optical and drive-motor train views, PCB block diagrams with electrical parts layouts, 14 timing charts, the KM-1525 general wiring diagram, and two KM-1530/KM-2030 general connection diagrams. Appendixes add maintenance-parts lists and periodic maintenance procedures.

Main-PCB replacement includes machine-data backup and restoration. Firmware sections identify the flash tool assembly P/N 35968010, memory tool PCB P/N 2AV68030, model-specific master ROMs, and the separate operation-unit PCB update used with the 20-cpm configuration.

Exploded Parts and Ordering References

The KM-1525 Parts List contains 14 exploded sections. The KM-1530/KM-2030 catalog adds 16, including dedicated KM-2030 cassette and deck-unit views. Together they cover exterior panels and frames, cassettes, the paper path, original holder, optical and laser sections, imaging unit, fixing and drive sections, electrical components, operation units, accessories, and options.

Each drawing is paired with a numbered parts table. Symbol keys distinguish orderable service parts from non-supplied items and show components nested beneath assemblies. Alphabetical indexes cross-reference part numbers to figure numbers and regional quantities, while screw-classification pages decode the fastener abbreviations used in the illustrations.

Important Repair Notes and Scope

The safety and handling sections warn that leaving the photoconductor exposed during open-machine repair can damage the drum, and that only the specified fixing thermostat or thermal fuse may be used. Main-PCB replacement also depends on preserving machine data and following the correct firmware path.

Disconnect power before disassembly, use caution around high-voltage charger sections, never disassemble the laser optical unit, and allow the fixing section to cool before repair. Full internal overhaul of optional document feeders and finishers is outside these main-copier manuals; their coverage is limited to copier-side interfaces, operating checks, Maintenance Mode functions, and related fault references.
