Article ID: ART181225 | Date published: 01/17/2023 | Date last updated: 01/17/2023


This article shows how to adjust the line length of the imagePROGRAF TC-20. This will ensure that lines in CAD drawings are printed at the correct length.


To ensure that lines in CAD drawings are printed at exactly the right length, use Adjust feed length to adjust the amount that paper is advanced.

There are two options in Adjust feed length : Print alignment pattern and Change adjustment values.

 We recommend executing the adjustment if you have changed the paper type or paper size.

 Always check the Set priority values before adjustment.

 You will need a roll at least 11.69 in. (297.0 mm) wide and a high-precision ruler.

Follow the procedure below to adjust.

  1. Load paper.

     Always make sure the loaded paper matches the type of paper specified.

    Adjustment cannot be completed correctly unless the loaded paper matches the settings.

  2. Select Setup icon (cog) (Setup) on the HOME screen.

  3. Select Maintenance icon (screwdriver and pliers) Maintenance.

  4. Select Paper feed adjustment.

  5. Select Adjust feed length.

  6. Select Print alignment pattern or Change adjustment values.

    • If you select Print alignment pattern:

      The test pattern is printed for you to measure the scale and calculate the discrepancy.

      The scale bar prints "Millimeter" in 50 mm increments and "Inch" in 1-inch increments.

      Test pattern

    • If you select Change adjustment values:

      No test pattern is printed.

      Instead, you will measure a document already printed to determine the discrepancy.

  7. Select the amount of discrepancy.

    If the scale is shorter than the actual size, use a positive setting value. If it is longer, use a negative value. The feed amount can be adjusted in 0.02% increments.
