HP DesignJet Z6 Pro 64in error 86-13: Carriage issue

HP DesignJet Z6 Pro 64in error 86-13 is a carriage motion fault code, indicating the printer has lost its ability to position the print head assembly accurately. This is usually due to an obstruction or the carriage sensor being unable to read the encoder strip. Checking for debris in the carriage rail is the essential first step to restoring normal printing operations.

Common causes

  • 1Paper debris in the carriage path.
  • 2Dirty or scratched encoder strip.
  • 3Ink spray blocking carriage sensors.
  • 4Drive belt degradation.

Solutions

Quick Diagnosis

If 86-13 appears, power off the printer and try to move the carriage. If you feel resistance, look for debris inside the path.

Step-by-Step Solution

  1. Turn off the plotter and unplug.
  2. Remove any paper scraps from the printing area.
  3. Examine the clear plastic encoder strip above the print zone.
  4. Clean the encoder strip with distilled water and a microfibre cloth, very carefully.
  5. Power on to allow for sensor recalibration.

Prevention and Maintenance

Keep the printer area clean of paper dust. Regularly check for any ink buildup that could interfere with sensors on the carriage itself.

When to Call a Technician

If the carriage is clear and the encoder strip is clean, there may be a failure of the carriage sensor itself which requires specialized repair.
