Laser Assembly 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 this 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. Never place a mirror or a reflective tool or object in the laser beam path. 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 Assembly or any laser component that displays a Laser Warning Sticker. · Use caution when you are working around the ROS Assembly or when you are performing laser related repair procedures. · Do not disassemble the printer in such a way that the laser beam can exit the print engine during a print cycle.

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

Warning Labels
Throughout the printer, warning labels are displayed on potentially dangerous components. When you service the printer, check to make sure that all warning labels are in place. Read and obey all warning messages.

Section 1. Service Flowchart
If you choose to use this technical manual as a service manual, we have included a Service Flowchart that outlines one possible approach to troubleshooting and repair of the printer. The Service Flowchart is merely an overview of the path a service technician could take, using this technical manual, to service the QMS 3260/4032 base printer engine and options.
To use the Service Flowchart, start at Block 1 to identify the problem. After you have identified the problem, return to the Service Flowchart and proceed to Block 2 where you inspect and clean the printer (a through cleaning frequently solves many printer problems). You continue down the Flowchart, in this manner, always returning to the next block in the Service Flowchart after you have completed the tasks outlined in the current block. If you choose not to use the Service Flowchart, we recommend that you start at the appropriate Fault Isolation Procedure (FIP) Flowchart and proceed from there. In many cases, merely replacing the Print Car-

Fault Isolation Procedures

Section 2. The FIP Flowchart
If you used the Service Flowchart, it should have directed you to this section. Follow the FIP Flowchart, located at the end of this section, to analyze your printer problem.

How to Use the FIP Flowchart
1. 2. 3. 4. 5. 6. 7. 8. If the LCD displays an error code; go to the ERROR CODE box. If you a printer operation problem; go to the PRINTER PERFORMANCE box. If you have an print image problem; go to the IMAGE QUALITY box. Follow the arrow leading from your problem box to the individual Primary FIP (Fault Isolation Procedure) that corresponds to your error code, printer operation problem, or print image problem. Follow the instructions presented in the FIP. If a FIP instructs you to perform a diagnostic test, refer to Section 8 Running Printer Diagnostics. Voltage and resistance values presented in the FIPs are an approximation. Actual readings may vary from the stated values. Primary FIPs may direct you to a Secondary FIP. In the FIP Flowchart, the relationship between Primary and Secondary FIPs is represented with dotted lines.

How to Follow a FIP (see the sample FIP below)
1. Each numbered step in a FIP instructs you to perform a certain action or procedure. 2. The action box may contain additional information and numbered substeps you must follow to perform the action. 3. The action is followed by a question. 4. If your response to the question is Yes, then follow the instructions for a Yes reply. 5. If your response to the question is No, then follow the instructions for a No reply. 6. FIPs often ask you to take voltage readings at certain test points within the printer. Sections 11 and 14 contain information on test point locations and signal names. 7. FIPs often ask you to replace a printer component. Section 10 Removal and Replacement Procedures provides you detailed steps for removing and replacing all major parts of the printer.

Fault Isolation Procedures

Using Printer Diagnostics
Remove this section if you do not use the Control Panel MCU PWB connection for printer troubleshooting.

FIPs often ask you to perform an output test or an input test. You use the printer Control Panel, reconnected to a specific P/J on the MCU, to access and run the Diagnostics that are presented in this manual. The Control Panel LCD displays two lines of text, with sixteen characters per line. The text is make up of printer codes and messages that are generated by the MCU PWB. The buttons are used to select and control Diagnostic functions.

SER776X

Refer to the Section 7 for a detailed explanation of how to use the Control Panel to run the available Diagnostic routines.

Fault Isolation Procedures

General Notes on Using FIPs
1. FIPs assume there is no malfunction in the printer controller (ESS). If you are unable to fix a problem using the FIPS, we recommend that you replace the printer controller. 2. FIPs frequently use new or "known good" components as troubleshooting tools. We recommend you carry a spare Print Cartridge (EP Cartridge), Fuser Assembly, MCU PWB, QMS Video Controller, and LVPS PWB. 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 A­B and P/J X­Y", 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 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 Print Cartridge and the Paper Cassette are installed, and the Main Interlock Switch is actuated. 9. All voltage values given in the FIPs are approximate values. Actual measured voltages may vary more than 25% from the values stated in the FIPs. The main purpose of most voltage readings taken in the FIPs is to determine whether or not a component is receiving the correct HIGH voltage value from the power supply and if gating (a voltage drop) occurs during component actuation. Gating signals may be nothing more than a pulse, resulting in a momentary drop in voltage that may be difficult or impossible to read on the average multimeter. 10. FIPs may instruct you to remove or replace a component. Refer to Section 10 Removal and Replacement Procedures 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.
