8.4.11 Updating of Paper Feeding Correction Value (Function code 58)
Function
To keep the paper feeding performance in the best condition for quality print, the controller
optimizes the rotation of the paper feed roller, using the correction value stored in the EEPROM on
the main PCB.
If you replace the engine unit, paper ejection roller, or head/carriage unit, you need to update the
paper feeding correction value according to the procedure given here.
