LCD Message List

When the printer detects errors that can be restored, it displays a service call error on the LCD,
as shown below.
Service Call
nnn: Error
Note! nnn is an Error code.
When a service call is displayed, the error code and accompanying error information is displayed
on the bottom row of the LCD. The meaning of the error code and the overview of the remedies
are indicated in Table 7-1-1.
