How to clean the cartridge contacts for HP LaserJet Enterprise 500 Color MFP M575dn printer?

To clean the cartridge contacts, consider these steps:
(Make sure that the HP LaserJet Enterprise 500 Color MFP M575dn toner cartridge is installed in the printer as soon as possible. Do not leave them out of the printer for more than 30 minutes, else it might damage the toner cartridges)

• For the cleaning process, turn on the printer.
• Open the cartridge access door and remove the cartridge shown in the error message.
• With the bottom pointing up, hold the HP LaserJet Enterprise 500 Color MFP M575dn toner cartridge by its sides and locate the electrical contacts on the toner cartridge. (The electrical contacts are the small gold-colored dots present on the toner cartridge).
• With a floss-free cloth, wipe only the contacts. (Be careful while cleaning the cartridge contacts. Do not smear any of the toner or debris anywhere)
• Locate the cartridge contacts in the print carriage.
• Wipe the contacts in the print carriage with a dry swab.
• After the whole process, reinstall the HP LaserJet Enterprise 500 Color MFP M575dn toner cartridge and close the cartridge access door.
• Check whether the issue is resolved or not. If you still receive the error message, turn off the printer and turn on back again. Note: If only one HP toner cartridge is causing the problem, you can remove it and use the single-cartridge mode to operate with only one cartridge.

What to do if the HP LaserJet Enterprise 500 Color MFP M575dn pages are slent or skewed?

• When the HP printer papers are skewing, you need to make sure that the paper you have loaded in the input tray is properly arranged to the paper-width guides.
