1.3.19 Updating of Paper Feeding Correction Values (Maintenance mode 58)

To match the paper feeding amount with the head nozzle pitch, the machine optimizes
the rotations of the paper feed roller and paper ejection roller, using the correction
values stored in the EEPROM on the main PCB.
If you replace the head/carriage unit or main PCB ASSY or remove the engine-related
parts, you need to update the paper feeding correction values according to the
procedure given below.
