Status Number
Status information (upper 4 bits)
Upper 4 bits display 0000.
Status information (lower 4 bits)
Lower four bits display 0010.
When status 8’s status information (upper four bits) displays 0 and (lower 4 bits) 2,
as shown above, if the bit pattern is fixed according to the conversion chart below,
at 0000 0010, bit 1 becomes 1.
Status 8’s bit 1 is a status which indicates a fixing assembly problem, and indicates
the cause of the printer’s poor condition is the fixing assembly.
