PRODUCT DESCRIPTION
EPSON Stylus CX3100/3200 |
Revision A |
1.1 Overview
This section describes the specifications for the SPC (Scanner, Printer, Copier) machine “Stylus CX3100/3200”.
1.1.1 Basic Functions
The functions of Stylus CX3100/3200 are as described below:
Printer function
The Printer function produces photo quality output on the Epson special coated papers with BorderFree feature.
Print head
Bk: 48 nozzles in each of 3 rows (144 nozzles in total) YMC: 48 nozzles for each
Scanner function
The image can easily be acquired on the PC by means of the “Scan” button.
The maximum optical resolution of scanning is 600 dpi x 1200 dpi and pixel depth is 48-bit at the ADC output, 24-bit when passing to a PC.
Standalone Copier function
The Product has the Standalone Copier function that reproduces photo quality copies on the Epson special coated papers without PCs. The use of the latest print technology mounted on the Product achieves the highest standalone copy speed among the same class of the products.
Standard Copy mode
This mode is used for the standard copier function. The bottom margin is 14 mm.
BorderFree Copy mode Photograph copy
Small Margin Copy mode
The minimum copy margin is 1.5 mm.
Reduced (Minimize) Margin Copy mode
This mode is basically the same as the standard copy mode, but the bottom margin is 3 mm.
Repeat Copy mode
Mini photo stickers can be produced.
2-up Copy mode
Two pages of the original is shrunk and printed on one page. Consumption of copy paper can be saved.
Mirror Copy mode
The original can be flipped from left to right and copied onto the Iron-on Cool Peel Transfer Paper.
1.1.2 Common
The specifications described below are common to the scanner and printer.

OPERATING PRINCIPLES
EPSON Stylus CX3100/3200 |
Revision A |
2.1 Overview
This Chapter describes the operating principles of the mechanism and electric circuits of EPSON Stylus CX3100/3200.
EPSON Stylus CX3100/3200 roughly consists of a printer and a scanner. The mechanism can be divided into the printer and the scanner. The electric circuit includes the Main Board circuit, Power Supply Board circuit, scanner carriage circuit and control panel circuit.
2.1.1 Mechanism
2.1.1.1 Printer Mechanism
The printer mechanism comprises the Carriage carrying the print head, the CR Motor for driving the carriage in the lateral direction in the printing range, the Capping Unit for preventing the print head from drying, the PF Motor for transporting the paper, the ASF Unit for loading paper by the driving force from the PF motor, and the Paper Eject Unit for ejecting the paper after printing.
