HP DesignJet 7xxC Series Printer - Solving Problems with Plot Position

If you do not find the solution to your problem in this document, other sources of help are:
  • The documentation supplied with the driver that you are using. For example, the online and printed documentation included in the following two drivers supplied with your printer:
    • HP printer drivers for AutoCAD
    • HP printer driver for Microsoft (R) Windows applications
  • The documentation supplied with your application software, for example the AutoCAD Reference Manual.
ISSUE: The plot is completely blank.
SOLUTION: Check the print cartridge(s) to ensure you have removed the protective nozzle tape from all of them. Do not forget that, after you remove or reseat a cartridge, the printer will run its automatic cartridge alignment procedure.
Cartridge(s) may be out of ink.
ISSUE: The output contains only a partial plot.
SOLUTION: Did you press Form Feed and Cut before all the data were received by the printer? If so, you have ended the data transmission and will have to print the plot again. (You normally do not need to press Form Feed and Cut to unload the plot.)
The I/O Setup/I/O Timeout setting may be too short. Increase the setting and plot again.
Some software may not write a proper file terminator at the end of the file. In this case, the printer will not know that the file is complete and will wait for more data until the end of the "I/O Timeout" period. By default, this period is 30 minutes, but you can change it in the menu to as little as 30 seconds.
The file may be too big for the printer’s memory.
There may be a communications problem between your computer and the printer. Ensure the interface cable is connected properly.
Ensure that your software settings are correct for your current plot size (for example, long-axis plots).
If you are using network software, ensure it has not timed out. (See the following issue.)
ISSUE: The plot is clipped.
SOLUTION: This normally indicates a discrepancy between the actual plotting area on the loaded media and the plotting area as understood by your software.
Check the actual plotting area for the media size you have loaded. Plotting area equals media size minus margins.
Check what your software understands to be the plotting area (which it may call "printable area" or "imageable area"). For example, AutoCAD assumes standard plotting areas that are larger than those used in this printer.
Check that the orientation of the media is the same as that assumed by your software. The front-panel Page format/Rotate option changes the orientation of a drawing and, on roll media, the orientation of the page. It is possible that a rotated plot on roll media may be slightly clipped in order to retain the correct page size.
You may have asked to rotate the plot from portrait to landscape on media that is not wide enough, for example a D/A1-size plot rotated on a D/A1-size roll.
If necessary, change the plotting area in your software. For example, in AutoCAD, specify User Sizes (see AutoCAD documentation).
The file may be too big for the printer’s memory. This is the case if the front panel displays "Out of memory - data were lost".
ISSUE: A long-axis plot is clipped.
SOLUTION: Does your software support long-axis plots?
Have you specified an appropriate media size in your software?
Ensure that the printer’s Page format/Size is set to Inked area.
ISSUE: The entire plot is in one quadrant of the correct plotting area.
SOLUTION: Is the page size configured in the software too small?
Are you sure that your software does not believe the drawing to be in one quadrant of the page?
Otherwise, this indicates an incompatibility between the software and the printer:
Is your software configured for this printer? For advice specific to your software, see either the documentation supplied with the driver or any Software Application Notes supplied with your printer.
If you still have not found the solution, try changing the printer’s Graphics Language setting on the front panel (Device setup/Lang).
ISSUE: The plot is unexpectedly rotated.
SOLUTION: Check the front-panel Page format/Rotate setting.
If Queuing and Nesting are both on, plots may be automatically rotated to save media.
ISSUE: The plot is a mirror image of your drawing
SOLUTION: Check the front-panel Page format/Mirror setting.
ISSUE: The plot is inaccurate.
SOLUTION: If you notice problems with accuracy, print the Service Config plot to see if the printer needs to be recalibrated.
ISSUE: The plot is distorted or unintelligible.
SOLUTION: The interface cable between your computer and the printer could be faulty. Try another cable to see if the problem is corrected.
If you are using a serial interface between the printer and your computer, make sure the printer’s serial interface settings match the settings and requirements of your software and hardware.
ISSUE: One plot overlays another plot on the same sheet.
SOLUTION: TheI/O Setup/I/O Timeout setting may be too long. Decrease the setting and plot again.
If Device setup/Lang is set to 7586,HP-GL/2 (the default), try changing the Terminator setting and send the files again.
ISSUE: Pen settings seem to have no effect.
SOLUTION: Either you have changed them in Pen settings/Define palette but forgotten to select that palette in Pen settings/Palette, or you expected the software-driven pen settings but the front panel Pen settings/Palette is not set to Software.
ISSUE: The printer produces a black and white plot when you expected a color plot.
SOLUTION: Check the front panel Color/Mono setting and the equivalent setting in your software.
ISSUE: The printer has printed a different plot than the one you were expecting.
SOLUTION: One possibility is that you have accidentally initiated one of the printer’s internal plots:
  • The Cartridge Alignment Plot. (A small pattern of lines without text.) This is printed automatically every time you replace, or reseat a cartridge
  • The Current Configuration Plot (A graphic and text plot with the current configuration details.) This is plotted by simultaneously pressing the two arrow keys on the front-panel.
  • The Sample Plot (A graphic plot with product information.) This is plotted from the front-panel menu Demos/Samples.
  • The Front-Panel Menu Plot (A text plot showing the complete menu structure.) This is plotted from the front-panel menu Demos/Menu.
  • The Service Configuration Plot (A text plot with service information.) This is plotted from the front-panel menu Utilities/Service Config.
  • The Palette Demo Plot (A plot with 256 colored squares.) This is plotted from the front-panel menu Demos/Palette.
ISSUE: The quality of a color plot is not as good as you were expecting.
SOLUTION: Select Best on the front-panel Print Quality key and plot again.
Did you specify the correct media type when loading? The highest line quality is only produced using Opaque Bond, Coated Paper, or Matte Film.
Your application-software driver may be overriding the Sharp lines selection on the front-panel menu.
Are you plotting something other than a line drawing, for example a CorelDraw! file? If so, you may want to experiment to improve the output quality by setting Sharp lines to Off on the front-panel menu, and plot again.
Are you plotting a CAD drawing with small raster images? Try setting Sharp lines to On, and plot again.
When loading the paper, specify "Heavy coated paper" on the front panel, rather than "Coated paper."
