HP Designjet 700 Series Printers - Noise Along the Carriage Path, General Y-Axis Troubleshooting
Noise is produced when the pen carriage cannot move freely.
Common causes are the Y-belt (carriage belt) being frayed or worn, obstructions or excess friction along the carriage path, the cutter failing to reach its home position, or worn or damaged Y-axis parts. Follow the instructions listed below to help solve these errors.
Follow up:
Troubleshooting Steps:
- Remove any obstructions such as jammed media from the carriage path.
(see blog post on How To Remove Paper Jams) - Clean and lubricate the carriage rails.
- Inspect the cutter, and replace if damaged or bent.
- Check the main belt for fraying or other damage. Replace the belt if needed.
- Verify the encoder strip is not damaged or does not touch the Carriage anywhere along the Y-axis. Replace the encoder strip if necessary.
- Verify the rear carriage bushing is seated correctly. To reseat it, stand behind the printer, and push in on the bushing with a flathead screwdriver until the bushing pops into place. If a pop is not heard, it is not correctly seated.
- If problems continue, replace the Y-motor, the Y-tensioner, and the idler pulley.
- Verify functionality.
NOTE: Attempt to verify printer functionality after each of the troubleshooting steps above. Functionality can be proven by turning the printer Off, then On, and printing several internal E or D size demo plots. If functionality is verified, no additional parts should be replaced.
