User manual

Plot Calibration: This test is for the fine adjustment of the control parameters used in the

Closed-loop Control ON: Absolute mode. Usually the platen accuracy has been adjusted

within the specification at the production facility before delivery of the TechSetter. The

user may run the Plot Calibration test for fine adjustment if there is a need. The procedure

is as follows:

1. Enter this test mode by pressing the ENTER key when “PLOT CALIBRATION...” is

displayed under SYSTEM menu, SYSTEM TEST item.

2. Once in the test mode, use the PARM+ or PARM- key to select either “Use internal

plot” or “Use external plot” mode.

The “Use internal plot” mode:

3. In this mode, the PARM+ or PARM- key may be used to scroll through the test length

choices among 36”, 48”, 60” and 72”. Press the ENTER key to select the desired test

length. The ITEM key may be used to exit this test mode.

4. Selection of different image patterns (normal grid, filled or blank interior as in the Platen

Accuracy test) is also available. Press the ENTER key to run the test which would

output an image of the selected length and pattern.

5. After the output image is printed, the message “W=xxxx L=yy S=zzzz” will be

displayed (W and L indicate the number of window slots and of lines used for internal

diagnosis. S is the total number of scan lines of the printed image. The user may ignore

these numbers unless there is an abnormality in the platen accuracy adjustment. In such

case, please contact the factory technical support.) . Press the CUT/PARM+ key to cut

off the output image.

6. Use an accurate scale to measure the length of the printed image.

7. After cutting off the output image, the nominal test length (such as 36.000”, ...) is first

displayed on the front panel. The user may use the PARM+ or PARM- key to enter the

actual measured length digit by digit. Use the ENTER key to move the cursor pointing

to the digit to be entered.

8. After entering the last digit, press the ENTER key.

9. If the user has entered an incorrect number carelessly, press the PARM+ or PARM- key

to restart the process of entering the measured length. After the correct number is

entered, press the ENTER key.

10. After the measured length is entered, the TechSetter will adjust its internal platen

accuracy parameter and save it in the nonvolatile memory.

11. The user may repeat the PLOT CALIBRATION test to confirm the corrected result, or

to perform one more round of adjustment if necessary.
