2.2  Printer Mechanism

2.2.1  Printer Mechanism

The Printer Mechanism for the Stylus CX3500/CX3600/CX3650 is newly designed. 
But, the basic component of the Printer Mechanism is almost the same as the previous 
printer (Stylus Photo R300/R310). And also, the Stylus CX4500/CX4600 is successor 
to the Stylus CX3500/CX3600/CX3650 and is the same as its Printer Mechanism. 
This printer consists of the Print Head, Carriage Mechanism, Paper Loading 
Mechanism, Paper Feeding Mechanism, Ink System. 
Like the previous printers, the Stylus CX3500/CX3600/CX3650/CX4500/CX4600 is 
equipped with two DC motors; one for the Paper Loading/Feeding Mechanism and the 
Pump Mechanism with the CR Lock Mechanism, and one for the CR Mechanism. The 
ASF Unit for the Paper Loading Mechanism uses rear entry front eject system. The 
Paper Feeding Mechanism uses the LD Roller and Retard Roller to feed paper to the 
Printer Mechanism in the same way as previous printers.
