1.5 Lamp Descriptions
Since this scanner does not have any LED indicator, it shows the various
conditions by turning on/off or blinking the lamp. Conditions indicated by the
lamp are as listed below:
Lamp: On
The scanner is in a normal condition.
Lamp: Blinking
The scanner is turned on before the transportation screw is unlocked.
Communication error
Fatal error except for lamp break has occurred.
NOTE:
Lamp: Off
The lamp goes off after 30 minutes.

1.6 Error Indications
Refer to Section 1.5 for the error indications.
COMMAND ERROR
Cause: Undefined command is detected.
Disposition: The scanner ignores a wrong command and
parameter(s), so it keeps the current settings or
default value effective. The scanner sends
NACK and waits for the next command and
parameter(s).
Indicator: No effect
Remedy: Error condition is cleared when the scanner
receives a correct command.
Indicator: The lamp starts blinking. (The lamp goes off after
30 minutes.)
The lamp does not light up when it has blown.
Remedy: (After the cause of the error is removed)
Turn the scanner off and then back on.
Connect the USB cable again.
Receiving of ESC@
Acceptable command: [ESC F, ESC f, ESC @]
COMMUNICATION ERROR
Cause: Wrong procedure is detected in the interface
communication.
USB cable was removed during communication.
Disposition: The scanner stops the ongoing job.
Indicator: The lamp starts blinking. (The lamp goes off in
30 minutes.)
Remedy: Turn the scanner off and then back on.
Connect the USB cable again.
Acceptable command: None
FATAL ERROR
Cause: The lamp is broken.
The scanner is turned on before the
transportation lock is released.
System breakdown
Disposition: The scanner stops the ongoing job.

OPERATING PRINCIPLES
CHAPTER

EPSON Perfection 610 Rev. B
CCD Sensor Board
2.1 Engine Mechanism
This section explains the engine functions and operating principles of the
EPSON Perfection 610. The engine mechanism has the two major parts; the
carriage unit (=scanning head) and the carriage move mechanism.
2.1.1 Carriage Unit
The carriage unit is composed of the following:
CCD sensor board (containing the CCD sensor)
Inverter board
Lamp (the light source)
Mirror and lens mechanism
This board includes the Color CCD line sensor (independent R,G,B) and
the sensor’s control and driver circuits.
Inverter Board
This board generates voltage used to drive the lamp. The board pressures
up +24VDC and converts it from direct current to alternating current.
Lamp
A white cold fluorescent lamp is used as the light source.
Mirror and Lens Mechanism
Light emitted to the document reaches the CCD sensor via the mirror and
lens mechanism in the carriage unit, where the light’s optical axis is
corrected. Note other scanners separates R/G/B components by switching
the light source between R, G, and B. In this scanner, however, it is
performed by the CCD sensor itself.

2.1.2 Carriage Drive Mechanism
A line-type color CCD sensor, which is included in the carriage unit, scans one
line at a time in the main scan direction (parallel to the carriage unit). To scan
next lines in the sub-scan direction after the first line, the scanner moves the
carriage unit with the CCD sensor in it along the sub-scan direction. The
scanned data is sent to the control board. Reading image for “n” line and
processing data for “N-1” line are simultaneously performed one after another.

Second Line
Main Scan
Direction
Sub Scan Direction by CR Movement
First Line
The carriage unit slides in the sub-scan direction along the guide rail. To slide
the carriage, the carriage (CR) motor drives the timing belt attached to the
carriage unit by conveying torque via the drive pulley and transmission gear.
Scanning start position is determined by CR HP sensor, which is located on the
control board. Since the CR motor is a stepping motor, it is controlled under the
open loop system. (See Figure 2-4.)

2.1.3 Power Supply Circuit
Power supply circuit board in this scanner generates direct current necessary
for driving the controller board and scanner engine.
See Table 2-1 and Table 2-2 for the power supply circuit board specifications
and the protection circuits for each output voltage/current, respectively. Figure
2-5 shows the power supply circuit diagram.

6.1 Overview
This chapter provides information necessary to keep the scanner function in
optimum condition constantly and to prevent troubles.
6.1.1 Cleaning
Perform cleaning when stain is noticeable. Stain on the document glass,
particularly, has a direct effect on scanned images. Therefore, be sure to clean
the glass well to remove stain thoroughly.
CAUTION
Outer Cases
Wipe dirt off with a clean cloth, moistened with water and squeezed tightly.
To remove severe stains, use a neutral detergent.
Document Glass
Remove dust and paper debris with a dry, clean cloth. If the dirt is severe
or foreign matter is stuck on the glass, use a cloth soaked with neutral
detergent. If any trace is left, wipe it off with a dry, clean cloth again.
Never apply any organic solvents such as thinner or
benzene, since these may deteriorate plastic and rubber
parts.
