About this Manual Remove paragraphs two and three on this page. This manual contains technical and service information for the QMS 3260/4032 (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.
Symbols Used in This Manual Various symbols are used throughout this manual to either provide additional information on a specific topic, or to warn of possible danger present during a procedure or action. Be aware of all symbols when they are used, and always read NOTE, CAUTION, or WARNING messages. A Note may indicate an operating or maintenance procedure, practice, or condition that is necessary to accomplish a task efficiently.
Safety information Follow all safety instructions to prevent accidents while servicing this 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.
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.

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.
tridge with a new one could solve the printer problem.
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.
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.
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.

Primary Fault Isolation Procedures The use of Diagnostic Test Print Image Quality FIPs may ask you to run a specific Diagnostic Test Print subroutine to help isolate the cause of an image quality problem. For each subroutine the printer circuity generates a test print that serves a single, diagnostic purpose. Follow the instructions in each FIP to evaluate the test print. Running Test Print Use this diagnostic routine to print a specific type of test pattern.
