1999 Sharp AR-C150 Color Copier Service Manual with AR-C100 References (P/N 00ZARC150/F1E)

This Sharp service publication, 00ZARC150/F1E, covers the 1999 AR-C150 digital full-color copier, with AR-C100 specifications, shared adjustments, and model-specific service references. It combines setup information, diagnostic simulations, and component removal and replacement procedures.

• Imaging-system repair: Removal and servicing of laser scanning units, OPC drum cartridges, developing units, main chargers, and the transfer belt assembly.

• Color calibration: CCD gamma adjustment, drum phase alignment, image registration, color balance, and image-density sensor calibration.

• Paper transport and fusing: Feed-roller and tray service, jam detection, fuser disassembly, heat-roller replacement, and oil-system maintenance.

• Diagnostic simulations: Sensor and load checks, self-diagnostic fault tables, trouble history, maintenance counters, and setup-data printouts.

• Optional equipment: Copier-side checks for the reversing automatic document feeder, duplex module, staple sorter, and large-capacity tray.

• Electrical reference: Overall block diagram, actual wiring charts, connector assignments, power circuits, and fuse/interlock diagrams.

This manual is suited to qualified copier technicians with experience in electrical testing and imaging-system calibration.

Scanner, Color Calibration, and Imaging-System Repair

The scanner documentation follows the three-line RGB CCD, image-processing boards, and laser writing units. Adjustments address scanner alignment, focus, image position, and color registration, with a flowchart for automatic and manual color-balance correction.

The calibration sections specify the SIT chart UKOG-0280FCZZ, gray scale chart UKOG-0162FCZZ, and service color test chart UKOG-0283FCZZ. Maintenance tables connect consumable replacement with counter resets and follow-up adjustments.

Color developers and color OPC drums have grouped replacement requirements for cyan, magenta, and yellow; black components have separate replacement provisions. Consumable tables and maintenance schedules cover toner-cartridge life, drum and developer replacement, and transfer-belt servicing.

The CCD section warns that loosening screws outside the specified adjustment points can make CCD-unit replacement necessary. Incorrect handling of the image-density calibration sheet can damage the transfer-belt cleaning blade.

Paper Handling, Fuser Service, and Fault Diagnosis

Paper-path cross sections identify the pickup, separation, transport, and exit components and their sensors. Fuser procedures extend to thermistors, thermostats, heater lamps, upper and lower rollers, the oil pump, and oil-applying components.

AR-C150 option checks cover the AR-RF1 reversing automatic document feeder and AR-DU2 duplex module, plus the AR-SS2 20-bin staple sorter and AR-LC2 large-capacity tray. Coverage centers on sensor inputs, motors, solenoids, and communication faults.

Image-density troubleshooting: F2-44/F2-45 entries distinguish sensor contamination, calibration-plate faults, and transfer-belt problems. Their checks and follow-up adjustments help connect a density error to the relevant sensor, belt, or control circuit before parts are replaced.

Machine-operations and user-program sections explain copy modes, key-operator settings, and user color calibration. Simulation tables distinguish shared settings from functions specific to either copier model.

Control Boards, Power Circuits, and Wiring Charts

Electrical references follow the PCU engine controls, ICU scanner and image-processing boards, and main and auxiliary DC supplies. Named drawings include the Overall Block Diagram, AC Power Circuit (100V/200V), Options I/F Section, CCD Section, LSU Section, and DC Circuit (Fuse + Interlock).

Setup and adjustment-value records support restoring machine settings after PWB or EEPROM replacement. High-voltage, laser, and hot-fuser work requires the qualifications and safety precautions specified in the manual.

A Preview of Developer and Fuser Specifications

These examples are a small selection of the manual's mechanical adjustment and consumable data.

The DV doctor gap is specified as 0.525 ±0.03 mm at two checking positions 40–70 mm from the doctor's ends. The documented fusing-pressure test specifies a 5.5–6.0 mm contact-band width at the center of the test sheet, with equal front and rear widths.

Consumable specifications list 650 g of developer for each black, cyan, magenta, and yellow unit, and a rated OPC drum life of 40,000 sheets.

Text Search, Wiring Detail, and PDF Contents

Search and diagram access: Service text is searchable, while the two operation-menu chart pages and many labels inside the block and wiring diagrams are not. There are no embedded PDF bookmarks. Small connector, pin, and wire-color labels require zooming for comfortable reading.

The download contains one printable, 333-page PDF in English. This total comprises 332 pages from the Sharp publication and one additional introductory page.
