Introduction

This manual contains technical and service information for the OKI B6100 (page per minute) Laser Printer. The information is based on and validated using the basic model printer. Expect some minor discrepancies in physical appearance, hardware count, and electrical readings due to engineering modifications and manufacturing changes during the life of the product.

The information in this manual is presented with the assumption that the OEM customer has designed their PWB ESS (Controller) to implement service diagnostics exactly as described in the Video Interface Specifications and in this manual.

This manual serves as both a technical reference manual and as a guideline for OEM clients who wish to prepare their own service manual. Other uses are prohibited.

This manual is prepared for use in the United States by Xerox International Partners, Technical Services Group. This manual is copyrighted. No portion may be copied, reproduced, submitted to, or read by XIP external customers without the prior consent of XIP.

Safety information

Follow these safety instructions to prevent accidents while servicing the OKI B6100 Laser Printer. Always be aware of the potential dangers that are present when you are working with electrical or mechanical equipment.

Power supply and electrical components

Before starting any service procedure, switch off the printer power and unplug the power cord from the wall outlet. If you must service the printer with power applied, be aware of the potential for electrical shock.

WARNING: Do not touch any electrified component unless you are instructed to do so by a

service procedure

Mechanical components

Hand crank to inspect sprockets and gears. Do not try to hand crank the printer while the Motor Assy is running.

OKI B6100 Laser Printer - Base Engine Technical Manual xi

Version 1.0

ROS Assy

WARNING: This printer uses a laser as part of the printing process. The laser beam is a very

powerful, straight, narrow beam of light that produces extreme heat at its focal point. The laser beam in the Asama printer is invisible. Although you cannot see the beam, it can still cause severe damage. Direct eye exposure to the laser beam may cause eye injury or blindness.

To avoid permanent eye damage, follow these directions:

• Before starting any service procedure, switch off the printer power and unplug the power cord from the wall outlet.

• Do not disassemble the ROS Assy or any laser component displaying a Laser Warning Sticker.

• Use caution when you are working around the ROS Assy or if you are performing laser related repair procedures.

• The OKI B6100 Laser Printer is equipped with two safety switches; the Switch Assy I/L Front (the switch that breaks the 24V circuit when the Cover Assy Front opens) and the Switch Assy I/L Rear (the switch that breaks the 3.3V circuit for the Motor Assy Exit when the Cover Rear opens). The Switch Assy I/L Front supplies the power to all internal components. The Switch Assy I/L Rear supplies the power to the Motor Assy Exit. It is extremely dangerous to cheat the Switch Assy I/L while the CRU is removed.

Safety Components

Make sure fuses, interlock switches, covers and panels are all functioning properly after you have reinstalled or replaced them.

Fault Isolation Procedures

2. The FIP Flowchart

If you used the Service Flowchart, it should have directed you to this section. Now, follow the FIP Flowchart to analyze your printer problem.

How to Use the FIP Flowchart

1. If you have an error code displayed on the screen of the Diagnostic Tool; go to the ERROR CODE box.

2. If you have a printer operation problem; go to the PRINTER PERFORMANCE box.

3. If you have a print image problem; go to the IMAGE QUALITY box.

4. Follow the arrow leading from your problem box to the individual FIP (Fault Isolation Procedure) that corresponds to your error code, printer operation problem, or print image problem.

5. Follow the instructions presented in the FIP.

How to Follow a FIP

1. Each numbered step in a FIP instructs you to perform a certain action or procedure.

2. The instruction is followed by a question.

3. If your response to the question is Yes, then follow the instructions for a Yes reply.

4. If your response to the question is No, then follow the instructions for a No reply.

5. FIPs often ask you to take voltage readings at certain test points within the printer. Appendices D and E contain information on signal names and test point locations.

6. FIPs often ask you to replace a printer component. Section 9 Removal/Replacement provides you detailed procedures for removing and replacing all

major parts of the Asama printer.

Fault Isolation Procedures

General Notes on Using FIPs

1. FIPs assume there is no malfunction in printer controller. If you are unable to fix a problem using the FIPS, we recommend that you replace the printer controller.

2. FIPs use new and "known good" components as troubleshooting tools. We recommend you carry a spare CRU, PWBA HKB MCU, and PWB ESS.

3. Unless indicated otherwise, the instruction "switch ON main power" means for you to switch ON printer power, and let the printer proceed through power-on diagnostics and warm-up until it is on-line and ready to print.

4. Conventions used to represent connectors:

P/J XX means a Plug and its corresponding Jack, are connected.

PXX means a Plug is disconnected. (Unless this plug is soldered to a PWB).

JXX means a Jack is disconnected. (Unless this jack is soldered to a PWB).

5. When you are instructed to take a voltage reading between "P/J A–B and P/J X–Y", place the red probe (+) of your meter on pin B of P/J A, and place the black probe (–) of your meter on pin Y of P/J X.

6. When you are instructed to take voltage readings between "P/J X and P/J Y" (without specified pin numbers), check all voltage carrying pins. Refer to the Wiring/Connection Diagrams for signals and pin numbers.

7. When you are instructed to take a voltage reading, the black probe (–) is generally connected to a pin that is either RTN (Return) or SG (Signal Ground). You can substitute any RTN pin or test point in the printer, and you can use FG (Frame Ground) in place of any SG pin or test point.

8. Unless a FIP instructs you otherwise; before measuring voltages make sure the printer is switched ON, the CRU and Cassette Assy are installed, and the Cover Assy Front and Cover Assy Rear are closed (Interlock Switch is actuated).

9. All voltage values given in the FIPs are approximate values. Actual measured voltages may vary somewhat from the given values.

10. FIPs may instruct you to remove or replace a component. Refer to Section 10 Removal and Replacement, for information on how to remove and reinstall a component.

11. When a FIP instructs you to replace a component, and that component is part of a larger assembly, you should replace the entire assembly.
