How to Read the Information Presented in this Chapter
6.1.1
Scanner Troubleshooting Outline
When performing any scanner troubleshooting, first perform a level 1 problem analysis to
determine the type of problem you are dealing with. Next perform a level 2 problem analysis to
troubleshoot the problem further.
When trying to determine the cause of the problem through this problem analysis, checklist, or
any other method, be sure to follow the instructions carefully.
When multiple causes are assumed for a problem, you are unable to determine all causes of
the problem in a single pass. As a result, you may conduct the same problem analysis multiple
times. In such a case, even though it is the same problem analysis, the action to be taken may
be different. So read its explanation carefully.
(1)
Level 1 problem analysis
The level 1 problem analysis is the first step to diagnosing a problem. The level 1 problem
analysis asks for the error code and various other symptoms of the problem in order to
determine you along to the level 2 problem analysis.
(2)
Level 2 problem analysis
The level 2 problem analysis is a set of diagnostic instructions categorized based on the error
code, whether or not its a paper jam, and many other problem symptoms. The method for this
diagnostic procedure uses instructions from the problem analysis or a checklist in order to allow
you to find the cause of the problem quickly and easily.
6.2
Level 1 Problem Analysis
During the level 1 problem analysis you will divide up and categorize the problem. If an error
message such as nnnn is displayed on the operation panel screen, use this unrecoverable
error code information to perform any necessary troubleshooting.
In any other case, use the symptoms of the problem as a guide and perform any necessary
troubleshooting from there (see section Problem Analysis Based on Symptoms).
