Adjusting the Print Position

Do this task when you load preprinted forms, adhesive labels, or other forms that require a precise registration that is not satisfied by the factory-set default registration.

Requirement For This Procedure

You must have a print job queued so that print data is available to print test pages during this procedure. You cannot complete this procedure without queued print data available.

In printing, the term registration refers to the relative print positions of images that are printed at different times. For example, when you process preprinted forms, the registration is good if the new image printed by the system printer aligns correctly with the preprinted image (as shown in Figure 25).

Figure 25. Good Registration
This is an image that illustrates a sample of good registration.

Print that extends beyond preprinted box edges and text that overlaps other preprinted text are examples of poor registration (as shown in Figure 26).

Note on Point of Origin:

When you adjust the print position of a defined forms identification name, the printer automatically stores the new point of origin as part of the current stored definition of that form. The point of origin remains in effect (even when the printer is powered off) until you change it later with the Adjust Print procedure or load another form.

This is an image that illustrates Adjust Print procedure window.

  1. Ensure that the form loaded in the printer is the form selected at the Assign Form to Load window.
  2. If the form name in the Assign Form to Load window is not correct, SELECT the Search... push-button to find the form name you want. When you have found the correct form name, SELECT the OK push-button twice to continue the Adjust Print procedure.
  3. If the target printer is Ready, stop the printer by SELECTING the Stop push-button on the main Display/Touch Screen window of the target printer.
  4. Display the Adjust Print window by doing one of the following:
  5. In duplex mode, if the side that is displayed in the Side to Adjust field is not the side you want to adjust, do the following:
    1. SELECT the Side to Adjust field.
    2. SELECT the side you want to adjust. The choices are:
      1. Normal Duplex Side 1
      2. Normal Duplex Side 2
      3. Tumble Duplex Side 1
      4. Tumble Duplex Side 2
    Notes to the Operator:
    1. For dual simplex, you have to go through this procedure twice if you want both printers to have identical forms. Do the procedure once to adjust the Form Name on Printer 1 and again to adjust the Form Name on Printer 2.
    2. The Front Sheet Sequence printer configuration value informs you which side of the duplex form is being printed on each printer in the system:
      • "Front First" Value - Printer 1 prints Side 1 (front side of form), and Printer 2 prints Side 2 (back side of form)
      • "Front Second " Value - Printer 1 prints Side 2 (back side of form), and Printer 2 prints Side 1 (front side of form)
      (See Configuring the Printer for details.)
  6. To print sample pages with the current registration values, do the following from the Display/Touch Screen:
    Requirement For This Procedure

    You cannot accomplish this step and the remainder of the procedure if a queued print job is not available.

    1. On the Adjust Print window, SELECT the Print Test push-button. This displays the Print Test window.
    2. If necessary, do the following to update the value in the Number of Pages box:
      • SELECT the Number of Pages box.
      • Use the keypad to type the correct value.
      • On the keypad window, SELECT the OK push-button.
    3. On the Print Test window, SELECT the OK push-button.
  7. Look at the pages just printed (located above the transfer station) to determine how much to adjust the print position.
    Things To Keep In Mind When You Adjust the Print Position:

    Print jobs with data closer than 20 mm (about 1 inch) to the fold perforation or from the edges of the forms do not have the full adjustment range. For example, if the job has data that prints 10 mm (about ½ inch) from the fold perforation, the maximum amount that image can be shifted is 10 mm (½ inch) toward the page perforation. If you attempt a larger vertical adjustment, Print Error Marker (PEMs), which the host system turns on or off, can occur.

    Note:
    The horizontal (H) and vertical (V) values vary depending on the print resolution (PEL) that you selected for the printer.
    How This Procedure Works:

    Doing this procedure lets you change the point of origin on a page by adding to or subtracting from the vertical and horizontal starting positions.

    Figure 27 illustrates the default point of origin (vertical=0, horizontal=0). It also shows the range of possible adjustments, which are not drawn to scale, when the print resolution is set to 480 DPI. The maximum adjustment in any direction from this position is about 6 inches.

    Note:
    The Infoprint 3000 printers show a range of either ±2880 for 480 DPI or ±3600 for 600 DPI.
    What To Do If the Adjustment Required Is Out of Range:

    If more than 20 mm adjustment (from 0) is required, refer the application owner to the Forms Design Reference for Continuous Forms Advanced Function Printers.

    The vertical and horizontal adjustment directions are always relative to the process direction (the direction that forms are moving through the printer). The vertical adjustment moves the point of origin on a line parallel to the forms tractor feed holes (the process direction). The horizontal adjustment moves the point of origin on a line that is at 90° (perpendicular) to the forms tractor feed holes. See Figure 27.

    Be aware that the printed output can be rotated when printed.

    Imagine that your sample page shows that the text is printing too high and too far to the left in relation to the preprinted form. To correct this situation, increase the vertical and horizontal positions (to move the point of origin down and to the right). Figure 28 shows the result of changing the vertical position to +7 and the horizontal position to +6. (The figure is not drawn to scale.)

    Note:
    The horizontal (H) and vertical (V) values vary depending on the print resolution (PEL) that you selected for the printer.
    Operator Tips

    • Once you have determined the adjustments for a particular form, you can make a note of the adjustment values on the Form Identification Work Sheet.
    • Be aware that occasionally some maintenance procedures can affect print position adjustment. If this happens, adjust the print position as needed.
  8. To make a horizontal adjustment, do the following:
    1. SELECT the Horizontal Adjust Amount field. This displays a keypad window.
    2. Use the +/- push-button on the keypad window to set the sign of the change you will make.
    3. Enter the new value, then SELECT the OK push-button to return to the Adjust Print window.
      Operator Tips
      • When you increase the horizontal value by one, you move the origin toward the right side of the form by one pel.
      • When you decrease the horizontal value by one, you move the origin toward the left side of the form by one pel.
  9. To make a vertical adjustment, do the following:
    1. SELECT the Vertical Adjust Amount field. This displays a keypad window.
    2. Use the +/- push-button on the keypad window to set the sign of the change you will make.
    3. Enter the new value, then SELECT the OK push-button to return to the Adjust Print window.
      Operator Tips

      • When you increase the vertical value by one, you move the origin down toward the trailing page perforation by one pel.
      • When you decrease the vertical value by one, you move the origin up toward the leading page perforation by one pel.
  10. To print a sample to test the new values, do step 6 again.
  11. If the registration is still not correct, repeat steps 7 through 10.
  12. If the registration is satisfactory, SELECT the OK push-button on the Adjust Print window.
  13. Make the printer Ready by SELECTING the Ready push-button on the Display/Touch Screen window for the affected printer.
    Operator Tips

    • After the printer has run for a few seconds, SELECT the Stop push-button on the Display/Touch Screen window for the affected printer. Then look at the output to ensure that the print position is still correct. Sometimes the print position changes slightly when forms move at full speed.
    • Most applications generate a few sample pages at the beginning of each job so that you can adjust the forms without losing any output. If you need more sample pages to test, ask the host system console operator to restart the job.
