Laser Printer Troubleshooting
Unlike with PCs, laser printer maintenance follows a fairly well established procedure.  Follow these steps to insure a long, healthy life for your system.

Keeping it Clean
Laser printers are quite robust as a rule.  A good cleaning every time you replace the toner cartridge will help that printer last for many years.   

Periodic Maintenance
Although keeping the printer clean is critical to its health and well being, every laser printer has certain components that will need to be replaced periodically.  Your ultimate source for determining the parts that need to be replaced (and when to replace them) is the printer manufacturer.  Following the manufacturer’s maintenance guidelines will help to ensure years of trouble-free, dependable printing from your laser printer.

Laser Printer Problems

Blank Paper - Blank sheets of paper usually mean the printer is out of toner or transfer corona wire
Black Paper
– primary corona wire
Dirty Printouts –
Clean Printer and Fuser using maintenance program
Ghosting, Vertical White Lines, Blotchy Print or No Printout
usually you need to shake the toner
Paper Jams – To much paper, misalignment, wrong paper and check sensors if no paper causing paper jam
Lines, Smearing, Not Fused – Scratch in the EP drum, Dirty Transfer Corona, Fuser needs to be replaced

Pulling Multiple Sheets
If the printer grabs multiple sheets at a time, first try opening a new ream of paper and loading that in the printer.  If that works, you’ve got a humidity problem.  If the new paper angle doesn’t work, check the separation pad on the printer.  The separation pad is a small piece of cork or rubber that separates the sheets as they are pulled from the paper feed tray.  A worn separation pad will look shiny and well, worn!  Most separation pads are easy to replace. 

Warped, Overprinted, or Poorly Formed Characters
Poorly formed characters can indicate either a problem with the paper (or other media), or a problem with the hardware. 

Wavy Image – Defective Laser Scanner

Strange Sizes – User mistake (printer settings) or wrong paper

Reverse Power Up – Turn on Laser Printer first before you turn on PC
