HP Designjet 650C Series Printers - System Errors 030001-030003, Switch Power Off Check Pen Path, Noise Along Carriage Path

In this document:

End of Support Drawer Statementback to table of contents

Hewlett-Packard guarantees support for five years after the end of production of its large format printers. Since the HP Designjet 650C has been out of production for a number of years, the parts and sub-assemblies may no longer be available to complete the repair. If the customer has a service agreement or contract, follow normal contract call logging processes (regardless of parts availability).

If the printer is not covered by a service agreement or contract, notify the customer about parts availability issues that will limit the ability to perform printer repairs.  If the customer still requests service and parts are available, follow normal trade call logging processes to avoid escalation. 

Introductionback to table of contents

The errors listed in the document title are displayed when the pen Carriage cannot move. Common causes are obstructions in the Carriage path, excess friction along the Carriage path, the cutter failing to reach its home position, and worn or damaged Y-axis parts. Follow the steps listed in this document to accurately determine the cause of the failure and to replace the appropriate parts.

Checking for obstructions in the carriage pathback to table of contents

  1. Manually move the carriage to the home position on the right and left sides, check for resistance along the carriage path.
  2. Check for any obstructions causing the cutter not to reach its home position.
  3. Check that the service station sled housing is installed correctly.

example

  1. Check carriage and encoder interaction. The carriage and encoder should not touch anywhere along the Y-axis.
  2. Check both main and small belts for missing teeth or fraying.

Cleaning and lubricating the carriage railback to table of contents

Wipe the entire rail with a soft cloth. Place two small drops of lubricant on a soft cloth to lubricate the rail.

Cleaning the encoder stripback to table of contents

Wipe the encoder strip with a water-dampened soft cloth. Check for visible damage. If necessary, replace the encoder strip.

Performing a Y-friction service testback to table of contents

  1. Turn the printer on.
  2. Press ENTER.
  3. Use the arrow keys to scroll to the Utilities menu display.
  4. Press ENTER.
  5. Simultaneously press the ENTER and UP arrow keys to access the Service Tests submenu.
  6. Use the arrow keys to scroll to Y-Friction.
  7. Press the ENTER button to begin the test.

The pen carriage will be moved along the slider rods with, and without the cutter assembly. A range of PWM signals is required to move the carriage and is measured and displayed for both cases (with and without the cutter). The test is used to check for excessive friction in the Y-axis. Excessive friction could cause servo shutdowns.

The display will show four numbers: the first number is with the cutter engaged, and the last three numbers are with the cutter disengaged. Replace Y-axis parts if the values are greater than 90. If Y-axis parts are replaced, perform the calibrations as listed below.

Edge sense calibrationback to table of contents

  1. Press ENTER at the Status display.
  2. Use the arrow keys to scroll to the Utilities main menu. Press ENTER.
  3. Simultaneously press the ENTER and UP arrow keys to access the Service Test menu.
  4. Scroll to Edge Sense Calib, and press ENTER.
  5. Messages on the display will indicate when to load media for the calibration to proceed. Part of the calibration procedure is an automatic performance of the pen alignment procedure. The calibration takes approximately four minutes to complete.
  6. Stay in the Service Tests submenu to perform the next calibration.

Drop detect calibrationback to table of contents

  1. Using the arrow buttons, scroll to Drop Detect Calib, and press ENTER.
  2. Press ENTER when calibration is complete.
  3. Stay in the Service Tests submenu to perform the next calibration.

Accuracy calibrationback to table of contents

  1. Use a sheet approximately 24 x 36 inches or roll media. To get the best results for an accuracy calibration, a polyester/matte film should be used.
  1. Load the media. If using D-size media (24x36 inches) load the short edge as the leading edge in 24-inch models and the long edge as the leading edge for 36-inch models. E-size media (36x48 inches) can also be used on 36-inch models.
  2. Using the arrow keys, scroll to Accuracy Calib, and press ENTER.
  3. Press the UP arrow key to select Create plot. A "Creating calibration plot" message will be displayed.
  4. Wait until the "Remove media/Continue" message displays, then remove the media.
  5. Press the DOWN arrow to Continue. The "Create plot / Measure plot" message displays.
  6. Press the DOWN arrow to select Measure plot.
  7. Rotate the plot so that the edge with arrows point to the leading edge, reload the plot with print side down.
  8. The printer will load the plot and measure the alignment marks using the edge sensor on the pen carriage.
  9. Press the DOWN arrow to continue when the "Calibrate done/Continue" message is displayed and the plot is fed out. The accuracy calibration is now complete.
  10. Verify printer functionality. Perform media loading procedures with roll and sheet (preferably larger than 8.5 x 11 inches) media, two times each.
