This chapter explains the remedies for errors detected by the self-diagnostic function as
well as the check points on a fault phenomenon basis, which are required for efficient
troubleshooting at occurrence of any error.

status of each section, and uses an LED indication to show the error state.This function
detects the following error states, and their remedies are as described below.
FATAL ERRORS
The status is defined as an error as soon as the paper feed/ejection command is
received.
