My HP LaserJet makes a grinding noise when it is started after installing HP LaserJet Pro M277dw toner cartridges. How can I stop the noise?

This type of problem may be caused by a paper jam or a carriage stall. To prevent the noise, perform the following steps:

• Turn off the printer.
• Detach the power cable from the back of the HP printer.
• If the carriage moves to the center, or if the service station is lowered remove the HP LaserJet Pro M277dw toner cartridges. Check for any broken parts inside the printer.
• Close the top cover of your printer.
• Separate the rear access door or the automatic two-sided printing accessory. Now check for the paper jams or paper obstructions. Remove any paper block.
• Change the rear access door accessory or the automatic two-sided printing accessory. Close the top cover of the printer.
• Plug back the power cable.
• Power on the printer, and replace the HP LaserJet Pro M277dw toner cartridges if possible. If the carriage moves and there is still a grinding noise, there might be a paper feed issue. If the carriage does not move, then there is a carriage stall issue.
• Install the HP LaserJet Pro M277dw cartridge and if the product has a solid power light, perform a self-test on it.
• If the issue still persists after completing all the preceding steps, contact the nearest service center or change your HP product.
