Study Notes
Printer Troubleshooting
Printer Problems and Techniques
- Common problems encountered in moving paper through a printer are discussed in detail, along with techniques for testing and verifying diagnosis.
- Image problems are troubleshooted by understanding how printers work and recognizing various types of image defects.
Image Problems
- Laser printers create an image in the same fashion, and the same causes are often responsible for a particular type of image defect.
- Image problems are discussed in detail, with guidelines for recognition.
Noises and Smells
- Noises are difficult to localize and sometimes impossible to eliminate, but common noises are covered with attention to customer complaints.
- Smells are easy to diagnose and usually caused by two things without a more immediate problem.
Error Messages
- A guidebook lists Hewlett-Packard error messages and a selection of others to guide diagnosis.
- Different OEMs take different approaches to repair and service, with HP taking a "black box" approach to isolate failures to the lowest assembly.
Troubleshooting Methodologies
- A systems approach breaks down the printer into assemblies and subassemblies that work together in various ways.
- Studying troubleshooting involves referring to various systems, with the systems themselves described in more detail.
- Diagnosing problems often requires logical thinking and understanding cause and cure.
- Ideal diagnosis involves having two machines, one malfunctioning and one working, to compare and isolate problems.
Learning Troubleshooting
- While experienced technicians may diagnose intuitively, a predetermined method is helpful for learning.
- A methodical approach helps to avoid getting lost in diagnosis and ensures a thorough understanding of printer troubleshooting.
