Reset operation
To start making adjustment with the program, execute the program on the PC that
connected to the target printer and follow the instruction shown on the PC monitor.
Since the mechanism design is the same with the EPSON Stylus Color 200, refer to
the service manual for EPSON Stylus Color 200, at Chapter 4 Adjustment, for the
detail procedures.
4.1.3.1 Zig-Zag Adjustment
This adjustment is required to specify the print timing control parameter that determines the
ink injection timing for each nozzle. If the adjustment is wrong, a vertical line printed within
single print pass become jagged.
Verify the check pattern printed by the program and specify the parameter until the check
pattern become aligned most properly.
4.1.3.2 Bi-D Adjustment
This adjustment is required to specify the control parameter that determines the print timing
in bi-directional printing. If the adjustment is wrong, the print position at each print direction
is not aligned each other.
Verify the check pattern printed by the program and specify the parameter until the check
pattern become aligned most properly.
4.1.3.3 Head Angle Adjustment
This adjustment is required when the printhead is replaced to new one. Every dot line
(raster) need to be parallel each other and the angle of the printhead, at which the
printhead is fixed on the carriage assembly, determines a parallel level.
The program prints the check pattern to judge the angle of printhead, and is the angle is not
correct, move the head angle adjust lever located at the right hand side of the carriage
assembly to a position with which the printed pattern become parallel.
