TROUBLE SHOOTING
Description
The PF roller cannot be rotated to the specified point.
An abnormal load is applied to the PF motor.
The main board is broken.
The target pressure cannot be achieved after the Pressure motor
has driven for a predetermined time period (40 seconds).
The home position of the Pressure pump cannot be detected
because the ridges of the accordion unit are adhered to each other,
or the Pressure pump home sensor is broken.
The Pressure pump has air leaks.
The pressure cannot be reduced.
The Pressure pump performed its movement cycle a
predetermined number of times (60 cycles), but the pressure does
not reach the specified level due to a malfunction of the pump,
sensor or motor.
Because of air leaks, the specified pressure cannot be obtained.
Air is leaking through a gap between the ink cartridge and the ink
cartridge holder due to an obstruction between them.
