HP Designjet CP Series Printers - Correcting Image Placement During Printing

Many of the problems described below may be caused by a third party Raster Image Processor (RIP). Most third party RIPs will overwrite the printer's front-panel settings. For testing purposes printing one of the internal demo prints rather than using the RIP is recommended.
If you do not find the solution to the problem here, other sources of help are:
  • The documentation supplied with the driver being used to manage the output from the software application to the printer
  • The documentation supplied with the application software

If the print is completely blank

  • Clean the contacts of the printhead nozzle-plate and the printhead carriage. Do not forget that after removing or reseating a printhead, the printer will run its automatic printhead alignment procedure. The printer will then run its calibration check for color quality.
  • If the front-panel graphics language setting is Automatic (default) try the other settings (PostScript(R) for a PostScript file, HP-GL/2 for an HP-GL/2 file etc.) and send the file again.

If the output contains only a partial print

  • Were CANCEL or FORM FEED and CUT pressed before all the data was received by the printer? If so, the data transmission was ended and the page will need to be printed again. (There is no need to press FORM FEED and CUT to unload the print.)
  • The I/O Setup/I/O Timeout setting may be too short. From the front-panel menu it is possible to increase the I/O Timeout setting to a longer period and send the print again.
  • There may be a communications problem between the computer and the printer. Check the interface cable.
  • Check to make sure that the software settings are correct for the current page size (for example, long-axis prints).
  • If using network software, verify that it has not timed out.
  • See if the Image is clipped as in the section below.

If the image is clipped

  • This normally indicates a discrepancy between the actual printing area on the loaded media and the printing area as understood by the software.
  • Check the actual printing area for the media size loaded. Printed area equals media size minus margins. For media size and margins, see the User’s Guide.
  • Check what the software understands to be the printing area (which it may call "printable area" or "imageable area"). For example, some software applications assume standard printing areas that are larger than those used in this printer.
  • Check that the orientation of the media is the same as that assumed by the 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 image on roll media may be slightly clipped in order to retain the correct page size.
  • You may have asked to rotate the page from portrait to landscape on media that is not wide enough, for example a D/A1-size page rotated on a D/A1-size roll.
  • If necessary, change the printing area in the software.

If a long-axis print is clipped

  • Does the software support long-axis prints?
  • Have you specified an appropriate media size in the software?
  • Unless it is a PostScript file, make sure that the printer's Page format/Size is set to Inked area.

If the entire image is in one quadrant of the correct printing area

  • Is the page size configured in the software too small?
  • Are you sure that the 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 general advice, see "Set Up Your Software" in the Setup Guide. For advice specific to the software, see either the documentation supplied with the driver or any Software Application Notes supplied with the printer.
  • If you still have not found the solution, try changing the printer's Graphics Language setting on the front panel (Device setup/Language).

If the image is unexpectedly rotated

  • Check the Front-Panel Page format/Rotate setting.
  • For non-PostScript files: If Queuing and Nesting are both ON, pages may be automatically rotated to save media.
  • For an explanation of rotation for PostScript files, see the User’s Guide.

If the print is a mirror image of your drawing

  • Check the front-panel Page format/Mirror setting.

If the print is inaccurate

  • If you notice problems with accuracy, print the Service Configuration print, as explained under Recalibrating the Printer for Accuracy in the User’s Guide, to see if the printer needs to be recalibrated.
  • Try running the image quality check to determine if the problem is connected to the ink system. See Solving Image-Quality Problems in the User’s Guide.

If the print is distorted or unreadable

  • The interface cable between the computer and the printer could be faulty. Try another cable to see if the problem is corrected.
  • If the computer is connected to the parallel port on the printer, verify that a genuine HP parallel interface cable is being used.
  • If the Front-Panel graphics language setting is Automatic (the default) try the other settings (PostScript for a PostScript file, HP-GL/2 for an HP-GL/2 file etc.) and send the file again.

If one image overlays another on the same sheet

  • The I/O Setup/I/O Timeout setting may be too long. From the front-panel menu decrease the setting and print again.
  • If Device setup/Language is set to Automatic (the default), try changing the Terminator setting and sending the files again.

If pen settings seem to have no effect

  • You have changed them in Pen settings/Define palette but forgotten to select that palette in Pen settings/Palette,
  • You expected the software-driven pen settings but in the front-panel Pen settings/Palette is not set to Software.

If the printer produces a black and white print when you expected a color print

  • Check the front-panel Color/Mono setting, and the equivalent setting in the software.

If the printer has printed a different print than the one you were expecting

One possibility is that you have accidentally initiated one of the printer's internal prints.
  • The printhead Alignment Print. (A small pattern of colored squares without text.) This is printed automatically every time you replace, or even reseat a printhead.
  • The Current Configuration Print. This is printed by simultaneously pressing the two Arrow keys on the front-panel.
  • The Image Quality print. This is printed from the Utilities/Service tests/Image quality print menu.
  • The Service print. This provides information needed for printer servicing, such as the current configuration, operating conditions (temperature and humidity), ink levels, and other statistics about printer usage.
Or you may have initiated one of the following internal prints that are printed underneath the internal prints menu on the printer's front panel:
  • PostScript demo
  • PostScript configuration
  • The Fonts print
  • The HPGL/2 Configuration print
  • The Printer Usage Information print
  • The menu print
  • The HPGL/2 Palette
