Confidential5.2  Adjustment5.2.1  Skew AdjustmentPURPOSEAdjust the gradient of the PH unit of each color and prevent the image skew from               
occurring.PROCEDURE1. After replacing or reinstalling the PH units, start the printer in the maintenance 
mode.2. The Calibration is executed automatically.3. After finishing the Calibration, print the Maintenance Status Sheet and check the 
each value of the Y/M/C by the Registration items which are at the bottom of the 
sheet. 
 
This value shows the adjusting the dial rotation step number to adjust the skew.
4. When the displayed value is out of the standard, open the front cover and adjust by 
turning the Skew adjusting dial (screw) on only the displayed value.
Standard: ± 4Adjusting direction: Positive value = Clockwise/Negative value = 
Counterclockwise
5. Close the front cover and then the Calibration is executed automatically again.6. After finishing the Calibration, print the Maintenance Status Sheet again and 
check that Y/M/C value of the “Registration” is within the standard. (In case Y/M/
C value of the “Registration” is out of the standard, adjust again from the 
procedure 4)

Confidential5.2.4  Writing USB IDPURPOSEThis printer includes USB interface as standard. A unique USB ID has been assigned to 
each printer to be identified by a host PC connected via the USB interface. The USB ID 
information is stored on the nonvolatile memory on the Main Board. Therefore, 
whenever the Main Board is replaced, the ID must be written to the new board. As for 
this product, the model ID information is stored, it must also be written to the board.REQUIRED TOOLThe program to be used for writing the USB-ID and the required operating 
environment are as follows.†Program name
EPSON Page Printer Main Board Initialization Tool
†Operating environment
„SO
Windows95/OSR2.0 or later, Windows98, Windows Me, Windows 
2000, Windows UP
„Interface to be used
USB
INSTALLING THE PROGRAM & BASIC OPERATION1. Copy a set of files of “Main Board initial setting tool” to a folder created on the 
PC.2. Double click on the program icon [
] to start up the program, and select the 
model name in the [Model Selection].
3. In the [Port Selection], select the port connected to the printer.
Figure 5-4.  Basic Operation

	

The set of files of “Main Board initial setting tool” must be stored in 
one folder.

	

The “Auto selection” allows you to search printers connected to the 
PC, and establish a connection with the first detected printer. When 
multiple printers are connected, however, specify the port name 
rather than using the “Auto selection” since a printer detected by 
the auto detection varies according to the communication status.
