6.5Maintenance Tool
6.5.1Self test printing
The SELF TEST button prints a setup report page which summarizes printer option settings. It can be used to easily check the electrical and mechanical states of the printer without the help of a computer. It also distinguishes between printer and computer errors, and confirms correct operation after an error recovery. The PRINT FONT button can be used instead. It prints font report pages which list all available fonts.
