How to Troubleshoot an HP LaserJet 1012
The HP LaserJet 1012 normally produces black and white printouts at a maximum resolution of 600 by 1200 dots per inch. The printer uses powdered ink, called toner, to recreate text and pictures from digital documents. The printer magnetically attracts the toner powder to specific spots on the paper, applying a high amount of pressure and heat to the page to set or fuse the toner on the page. If you notice abnormalities with the printer's operation, you can troubleshoot for the cause.
