“*2”: This value reflects continuous print *3 after replacing the ink cartridge. Depending on numbers of cleaning, this value become smaller. The first ink cartridge installed in this product will be used to bring it to printable condition.
“*3”: Continuous print: Continuous printing without stopping action due to power ON/ OFF or head cleaning.
Note : Ink in the cartridge freezes if it is left in the temperature below -16°C. Once ink is frozen, it takes approx. 3 hours to return to be usable condition if ink is in - 20°C and moved to in 25°C.

Revision C |
2.1 Overview
This Chapter describes the operating principles of the mechanism and electric circuits of EPSON Stylus PHOTO RX600/610, RX620/630.
Stylus PHOTO RX600/610, RX620/630 mainly, basically 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.
2.2 Mechanism
2.2.1 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.

PW Detector Control
There are two controlling methods using PW detector as follows:
Control of preventing print with no characters
Before start of print (immediately after paper head feed is complete) or during print, this control detects the existence of paper with PW detector, driving CR and PF motors and prevents print with no characters on paper sent to paper guide, which applies to only right and left edges of paper.
Control of restriction to run-off
This control detect paper edges with PW detector at the time of printing with no margin, and restrict the printing run-off quantity. It detects 4 edges when no margins are set for 4 sides of paper. For each mode, run-off area thin-out control is set that further compensates for run-off mask area at the time of printing with no characters.

256Mbit*16 SDRAM (2 units)
A6615 drives DC x 2 and DC x 2 with 1Chip to motor driver
SOC obtains wider band ranges by setting action frequency of local SDRAM to 96MHz
Copy function allows faster process with SOC to scan, and to generate 2- values, microwave, image buffer instead of going through CPU bus.
Equipped with a color LCD (2.5-inch DTFD liquid crystal display) as standard.
Low current allows LCD to reduce power consumption in low power mode as follows:
•Lowering power supply voltage
•Shutting off optical current for optical sensor
•SLEEP mode for motor drive
•Saving the power for printer with no exciting motor
•Saving the power for scanner by turning off the lamp
•Equipped with printer tray open sensor

TROUBLESHOOTING
EPSON Stylus PHOTO RX600/610, RX620/630 |
Revision C |
3.1 Overview
With this printer, almost all troubles can be coped with by using “EPSON Status Monitor 3” installed on the host personal computer.
Once an error occurs, the “EPSON Status Monitor 3” will appear as a pop-up window on the screen of the host PC. It will show details of how to cope with the trouble. In almost all cases, the user can recover the printer from the error, provided that the user follows the instructions indicated on the pop-up window.
In addition, the User's Manual for EPSON Stylus PHOTO RX600/610, RX620/630 describes detailed steps to be taken for recovery from typical errors.
3.1.1 Specified Tools
This printer does not require any specified tools for troubleshooting.
3.1.2 Preliminary Checks
Before starting troubleshooting, be sure to verify that the following conditions are all met:
The power supply voltage must be within the specification limits. (Measure the voltage at the wall socket.)
The POWER CORD must be free from damage, short circuit or breakage, or miswiring in the POWER CORD.
The printer must be grounded properly.
The printer should not be located in a place where it can be exposed to too high or low temperature, too high or low humidity, or abrupt temperature change.
The printer should not be located near waterworks, near humidifiers, near heaters or near flames, in a dusty atmosphere or in a place where the printer can be exposed to blast from an air conditioner.
The printer should not be located in a place where volatile or inflammable gases are produced.
The printer should not be located in a place where it can be exposed to direct rays of the sun.
The printer must be located in a well-ventilated place.
The printer must be placed on a strong and steady level table (without an inclination larger than 5 degrees).
The paper used must conform to the specification.
There is no error in handling of the printer.
Check the inside of the printer, and remove foreign matters, if any, such as paper clips, staples, bits of paper, paper dust or toner.
Clean the inside of the printer and the rubber rolls.
