If Printing Cannot Be Performed as Intended

This section describes cases where printing cannot be performed as intended under DOS/UNIX. Also, it explains how to resolve them.

Part of a drawing near the paper edges is not printed.

The entire area on the paper is specified as the output size, or the plotting origin of the data is not properly specified.

When "Paper Size" is selected for "23. Printable Area (Hard Clip)" on the RPGL Menu, the printable area of the machine is ignored. The entire area of the paper up to its edge is used for printing, but printing in the area 5 mm from each edge (top, bottom, left and right) of the paper is not guaranteed.

A drawing that should be printed on one sheet of paper is split over multiple sheets.

Check the settings for "Feed Timeout" under "Printer Features" of the machine.

Such a case may occur if the setting for "Feed Timeout" is too short. The duration that the data transmission is disrupted may differ depending on your application or operating environment, and you need to specify a value that is suitable for your environment in "Feed Timeout".

The printed drawing is not properly positioned.

The plotting origin of the data sent from the computer is not properly positioned. Use the settings for "7. Adjust Origin: Offset X-axis" and "8. Adjust Origin: Offset Y-axis" on the RPGL Menu to adjust the position of the drawing.

The image data appears faded.

Modify the setting in "44. Raster Image Density" on the RPGL Menu to "Dark" when "RP-GL/2 (Type1)" is selected in "6. Plotter ID".

Lines appear faint.

Modify the following settings:

  • Increase the line width.

  • Select a darker color.

If "57. Pen 0 Settings" - "56. Pen 15 Settings" on the RPGL Menu have been configured, change the pen density settings when printing in black and white.

Lines are not shown on the printed sheet.

Some applications may select No. 0 pen for output in certain cases. When printing in black and white, no line is printed if the density of the No. 0 pen is not changed from its default value (0%). Change the density of the No. 0 pen to a darker value.

When a drawing is printed in half tone or black and white, solid lines may appear dotted or broken, or may not appear at all, depending on the drawing position. If this occurs, set the line width to a wider value, or increase the density.

"40. Pen Setting Priority" is only valid for RP-GL/2.

Characters cannot be rendered using an outline font.

Characters can only be printed using an outline font when the data is sent by the font command (LB command). Configure the application you are using to output characters in character codes.

The drawing is misaligned towards the upper right corner.

The plotting origin is improperly placed. Check the settings for "6. Plotter ID" on the RPGL Menu. The plotting origin on "7475A", "7550A" and "RP-GL/2" is located in the bottom left corner. On other plotters, it is located in the center.

The drawing is not printed according to the specified settings, even when the pen width and density are specified on the RPGL Menu.

When "Driver / Command" is selected in "40. Pen Setting Priority" on the RPGL Menu, the pen width and density specified on the RPGL Menu are ignored, and those specified on the application side are applied.

In order to specify the pen width and density on the RPGL Menu, select "Machine Setting(s)" in "40. Pen Setting Priority".

"40. Pen Setting Priority" is only valid for RP-GL/2.

The edges of the lines and solids are not smooth; Solids are printed with small mesh.

Set the printing option as follows.

  • "Auto (Drawing)", "Thin lines", or "Compatibility" in "82. Dithering"

Print data is not rotated by 90 degrees, and it is not printed properly.

When printing on paper set in landscape orientation, select "On" in "93. Auto Rotation for Landscape Printing" on the RPGL Menu. If the problem persists even after selecting "On", select "Off" for the setting, or select "90 degrees" or "270 degrees" in "5. Axis Rotation".

When printing on paper set in portrait orientation, select "90 degrees" or "270 degrees" in "5. Axis Rotation".

Auto paper tray cannot be selected for RP-GL data.

Select either "Auto 2: Long Edge and Short Edge" or "Auto 2 + Red/Enlg Ratio: Paper Size" in "43. Method to Auto Select Paper Tray" on the RPGL Menu. If a paper tray is still not automatically selected even after the setting is changed, select "Entire Image" or "Auto" in "47. Method to Determine Original Size".

Auto paper tray cannot be selected for RP-GL/2 data.

Select either "Entire Image" or "Auto" in "47. Method to Determine Original Size" on the RPGL Menu.

You want to print half tone with higher tone.

Select the option suited for sent data in "82. Dithering" on the RPGL Menu.

If "Compatibility" is selected, the output is same as printing done with conventional RP-GL/2.

A drawing is not properly centered on the paper even when "On" is selected for "49. Centering".

  • For RP-GL, centering may not be performed correctly in some cases if "PS/IP Command" is selected for "47. Method to Determine Original Size" on the RPGL Menu. If this is the case, select "Entire Image".

  • For RP-GL/2, centering may not be performed correctly if "PS/IP Command" is selected for "47. Method to Determine Original Size" on the RPGL Menu in some cases. The margins may be included as part of the image to be centered. If this is the case, select "Entire Image".

The intended paper size is not selected when printing data of a regular size.

Select "Entire Image" in "47. Method to Determine Original Size" on the RPGL Menu, or configure "48. Margin Adjustment for Original Size".

The paper tray for custom-sized paper is not selected automatically.

Select "Org Sz Dtrmnd + R/E Ratio: Cor Valu" in "43. Method to Auto Select Paper Tray" on the RPGL Menu.

Data of a regular size is printed on a custom size when "Org Sz Dtrmnd + R/E Ratio: Cor Valu" is selected for "43. Method to Auto Select Paper Tray" on the RPGL Menu.

Specify the values on the submenu.

Paper is not fed from the custom-sized paper tray when printing custom-sized data.

Check custom sizes in the Print Settings List (RPGL).

The paper is not output in the intended orientation.

Change the setting for "103. Paper Orientation Priority" on the RPGL Menu. For details, see Changing the Paper Output Orientation.
