HP LaserJet 1018 - To check the printer high-voltage contacts

To check the printer high-voltage contacts
The printer has three spring-loaded pins (callout 1) that make contact with the high-voltage points on
the print cartridge. Verify that the pins are not dirty or corroded and that the spring-loading action is
functional. If the pins are dirty or obstructed, clean them. If they are damaged, replace the printer.
