1.0 INTRODUCTION 1.1 General Description The OYO Instruments TechSetter thermal imager is a computer to film imagesetter for graphic applications; it is a high-tech narrow-format and rugged imaging device designed for office use. It utilizes direct thermal printing technology; with few moving parts and no liquid chemicals to contend with, it operates efficiently and requires only nominal maintenance. 1.

2.0 PRECAUTIONS Do not turn off the main power or pull the power cord from the wall outlet without first turning off the POWER switch CB1 located on the back of the unit. The TechSetter employs only low voltage power supplies. However, hazardous voltages are present in the motor driver and in the AC input wiring. Reasonable safety precautions should be used to avoid electrical shock. Turn the unit off before replacing the media supply roll or servicing any component.
indicator will be lit green when the TechSetter performs certain functions, such as media cut and media form feed. 3.2 Keypad MENU This key allows the operator to cycle through the MENU selections during TechSetter OFF LINE: SYSTEM menu, JOB menu, IMAGE menu or Print the System Setup. ITEM This key allows the operator to cycle through all the ITEMs listed under one of the basic menus. ON LINE This key switches the TechSetter between ON LINE and OFF LINE.
ON LINE STATUS MENU ON LINE CUT/PARM + ITEM ENTER FEED/PARM - Fig.
3.3 Menu and Item Modes Table 1 shows the menus and menu items available with the basic TechSetter configuration. Detailed description of menu items is given below. After the TechSetter is powered up, the default state is ON LINE, with the ON LINE indicator lit green and the message "TechSetter 1400" displayed. Press the ON LINE key to switch the TechSetter to the OFF LINE state. After "... OFF LINE" appears on the display, pressing the MENU key causes the first menu (SYSTEM menu) to appear.
3.4 Parameter Selection ITEMs for each of the three menus (SYSTEM, JOB, and IMAGE) and their PARAMETER selections are listed in Tables 2, 3 and 4, respectively. In the ITEM mode, the item along with its default parameter value is on the display. Pressing the PARM+ or PARM- key will scroll up or down through all the available parameter values for that specific item. Any available parameter value can be selected and permanently saved by pressing the ENTER key when it is displayed.

4.2 Basic Tests CHECKERBOARD This test pattern displays checkerboard squares as shown in Figs. 4. FIG.
PLATEN ACCURACY This test checks the stepping accuracy of the TechSetter and prints the nominal distance lines with inch annotations. A sample pattern is shown in Fig. 5. Selections of different lengths ranging from one to eight feet and of different patterns (normal grid, filled, or blank interior) are available. The printed image may be measured with an accurate scale to determine the platen accuracy.
NIB TEST This test checks whether any failed nib of the print head exists. In addition to the leading and tail mark lines, a vertical line of a half-inch is plotted for every 8th nib; and at the end of each line, the next adjacent nib continues the plot. This pattern repeats until all the nibs have completed the plotting. A sample pattern is shown in Figs. 6. FIG.
4.3 Advanced Tests OPEN-LOOP CHECK This test is for the initial setting of the control parameters used in the Closed-loop Control ON: Absolute mode and is seldom needed by the user; however, it is provided as a diagnosis and adjustment tool in case that the platen accuracy can not be corrected by only utilizing the Plot Calibration test. In such case, it is recommended that the user contact the factory technical support before performing the OPEN-LOOP CHECK test.
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.
The “Use external plot” mode: 1. In this mode, it is assumed that the user has already had an output image of known nominal length and also measured the actual length of the image. The nominal ideal length of 36.000” is first displayed on the front panel. The user may use the PARM+ or PARM- key to enter the ideal length digit by digit. Use the ENTER key to move the pointing cursor to the digit to be entered. 2.
OVERLAY REF SET This test is for the setting of the control parameters used in the Closed-loop Control ON: Overlap mode. The procedure is listed below for reference: 1. Enter this test mode by pressing the ENTER key when “OVERLAY REF SET...” is displayed under SYSTEM menu, SYSTEM TEST item. 2. Once in the test mode, the PARM+ or PARM- key may be used to scroll through the “number of slots” choices among 640, 1280 and 1920. Note that 32 slots are approximately one inch long.
DOT SIZE TEST This test is similar to the Contrast Test, except that the image is of mesh pattern, with each square representing a 2x2 dot. The plot length is also selectable from 1” to 48”. A microscope or a magnifying lens may be used to examine the mesh patterns. This test may provide a guideline to selecting the appropriate contrast setting for those application images with demanding resolution requirement.
4.4 Guideline for Selecting Contrast Setting Note that the use of inappropriate contrast setting for a specific media may void the warranty on the print head. In order to achieve best image result as well as to prolong the life of print head, the following guideline may be referred: • 5.0 In the Contrast Test, an optical densitometer may be used to measure the optical density (o.d.) of the plot at each contrast setting, and a comparison of o.d. at all the settings can be made. Usually the curve of o.d.
5.3 Errors from Electronic Subsystems Interfacing • • • • • • "TE Interface error!" "Unknown TE error" "TEIF Comm error!" "TEIF Recv error!" "TEIF Timeout error!" "Unknown TEIF error!" Cause: Remedy: 20 Unknown TEIF (Thermal Engine interface) error or bad communication between the TE controller and the system processor. Reset the system. If the problem still persists, please consult the technical support.
6.0 USER PREVENTATIVE MAINTENANCE To increase the reliability of the print head, the following cleaning procedure is recommended. The use of this procedure is required to ensure continued warranty coverage of the print head and the imager. 6.1 How to Clean the Print head 1. 2. 3. 4. 5. 6.2 Wear latex (non-powder) disposable gloves (part # 540V1106001). Open 98% isopropyl alcohol cleaning wipes (part # 160V1106001). With the cleaning wipe, rub the entire length of the print head.
6.5 Cleaning or Changing the Media Cleaning Cloth Fig 1 Fig 2 Fig 3 Fig 4 Fig 5 Fig 6 Fig 7 Fig 8 Fig 9 Notes: 1. Open the Imager, remove the media roll and remove the old cleaning cloth. Clean up any residue remaining on the black velcro roller. Move the roller lock from the closed (see Fig 1) to open (see Fig 2) position by lifting up the locking pin. 2. Carefully pull the backing off beginning from the middle of the tape on both sides as shown in Fig 2.
8. Check to see that the cloth is secure to the black roller and smooth full length as shown in Fig 9. 9. Rotate the roller to let the overlap portion of the cleaning cloth face upward. 10. Close the roller lock by pushing the locking pin down as shown in Fig 1.
