HP Color LaserJet 4600, 4650, 4700, CP4005, 5500 and 5550 Printer Series - Grinding Noise During Warm-up or During Printing
The printer makes a grinding noise after it is turned on during warm-up and calibration. This same grinding noise during printing can also be heard while printing.
Go through the following troubleshooting steps to isolate the cause. From a READY state, do the following:
Disable cartridge check.
Remove all of the print cartridges.
- Verify if the white gear on the top right-hand side of the cartridge is damaged or unseated. See Figure 1. If so, replace the cartridge. If not, proceed to step 4.Figure : Damaged or unseated white gear on the print cartridge
Print a Configuration page. It will be blank because there are no print cartridges installed.
Listen to the printer and verify if the noise continues.
If the noise continues, troubleshoot using the DIAGNOSTIC MODE component tests.
If the noise is gone after removing the cartridges, printing the Configuration page, and running the component test, insert the cartridges one at a time to verify which cartridge is causing the noise.
note:It is important that you remove each cartridge before installing the next cartridge to make sure the correct cartridge has been isolated.
The white gears on the print cartridge are not meshing correctly inside the cartridge, or the internal component is frozen.
