HP Designjet 5000 and
5500 Series Printers - TWI: Excessive Noise When the Carriage Moves, Y-Axis Noise
In this document:
KRS document number: BPP90144
Last Updated: 04-Dec-2002
Minimum skill level: 2
An unusual noise is occurring when the carriage moves along the Y-axis. Common causes are lack of lubricant on the carriage rods, a faulty/damaged Trailing cable or carriage. Follow the steps listed below to determine the actual cause of the error and to replace the necessary parts.
NOTE: Cleaning and lubricating the carriage rail must be done prior to scheduling any on-site service for the product. This procedure often solves the issue without requiring service. The printer is shipped with a cleaning and lubing kit.
Parts required (part numbers are subject to change)
Troubleshooting steps
If parts are replaced or fixed in any of the steps listed below, attempt to verify printer functionality by turning the printer on and printing internal test prints. If functionality is verified, no additional parts should be replaced.
- Turn the printer off, using the main power switch located on the back of the printer.
- After 10-15 seconds, turn the main power switch on.
- If no error appears, attempt to verify printer functionality.
- If the error re-appears, continue with the remaining steps.
- Access the printheads (carriage) by initiating a printhead replacement.
- When the carriage has moved to an accessible location, turn the printer off using the main power switch on the back of the printer.
WARNING: To prevent possible injury, always remove the power cable from the back of the printer before manually moving internal parts, checking cables, or replacing parts.
- Open the top cover and lubricate the carriage rods using the cleaning kit shipped with the printer.
- Move the carriage assembly from left to right several times to lubricate the entire carriage path.
- Close the top cover.
- Turn the printer on and attempt to verify functionality.
- If the noise re-appears, lubricate the carriage rails again (steps 5-10) and attempt to verify functionality.
- If the problem persists, turn the printer off, then on (accessing service mode as instructed below).
- Enter the Service Tests menu.
- Perform a Scan-Axis test. If either of the values exceed the limit (FORWARDS Maximum PWM 225, BACKWARDS Maximum PWM 230), replace the carriage and trailing cable (refer to pages 8-46 and 8-36 of the service manual).
- Following replacement, turn the printer on (entering Service mode as instructed below).
- Access the Service Calibrations menu and perform the Scan-Axis, Service Station, and Carriage Height Calibrations.
- Following the calibrations, turn the printer off, then on, and verify printer functionality.
Performing service tests, service utilities and service calibrations
- Turn the printer on.
- When the "READY" message is displayed on the front-panel, scroll to the Printer Setup Options icon and press ENTER.
- Using the Arrow keys, scroll to Utilities and press ENTER.
- Once inside the Utilities menu, press the Up Arrow key and the ENTER key simultaneously.
- Scroll to the necessary menu (Service Tests, Service Utilities, or Service Calibrations) and press ENTER.
- Once inside the appropriate menu, scroll to the needed test and press ENTER to start the test.
