Paper Loading Mechanism
The Paper loading mechanism consists of the Change Lever in the Pump Unit, the Holder Shaft Unit including the Clutch mechanism and the ASF Unit. The Change Lever and the Clutch mechanism play a major role in the Paper loading mechanism as follows. 1. ASF home position detection function The ASF Unit on this printer does not have the ASF Home Position Sensor. Instead of the ASF Home Position Sensor, the Change Lever and the Clutch mechanism is used to detect the ASF home position. When the...
Capping Mechanism
The Capping mechanism covers the Print Head with the Cap to prevent the nozzle from increasing viscosity when the printer is in stand-by state or when the printer is off. The wiping operation is controlled by the Carriage Unit movement. This operation is usually performed with every CL sequence which is to absorb the ink from the ink cartridge, the ink cavity by the Pump unit. Following figure shows you the mechanism for the wiping operation. When the Carriage Unit is in the home position, the...
