How Repair Your Own Laser Printer
Having a printer repaired by a service company can be a pretty expensive proposition so we've compiled a checklist below that may assist you in fixing it yourself.
Paper Jams Paper jams is common. To clear the jam pull the paper out gently in the same direction it was headed and then checks for any obvious obstructions. If the jams persist the usual cause is worn pickup rollers. Over a period of time the rollers wear down and become slick and don't pull the paper in fast enough. If the paper is stopping in the fuser section it might be a bad gear or some debris causing the jam.
Image Problems Most image problems are caused by a bad toner cartridge. If you have any streaking, light/dark areas or repetitive spots on your print, replace the cartridge and see if it clears up. This is common when using poorly remanufactured cartridges. Some recyclers don't replace the image drum and they should because the original drums are only designed to last for the expected toner life. If problems persist after replacing the cartridge the next area to look at would be the fuser. The heat rollers can become torn or warped after a period of time causing an image defect.
Maintenance Kits On most of the newer printers, HP has determined the average life span of the consumable parts and has a maintenance message programmed in to appear after a certain amount of pages have been produced. The message will be something like "PERFORM USER MAINTENANCE" depending on what model you have. This is just a rough estimate. Some of the parts may go before this message appears and some will last long after. You can get a maintenance kit, which usually contains the fuser, feed rollers and certain other high mortality parts depending on the model. The newer ones are designed to be user replaceable and don't require a skilled service technician to install. It's a good idea to have one since these kits will usually take care of most of the problems you will ever have.
Paper, Envelopes and Labels The quality of what you feed into your printer can also be a factor. Certain types of paper can cause feed problems. Envelopes and labels put more strain on the machine than plain paper. Be especially careful with labels as these can sometimes slide off inside the fuser or toner cartridge. Humidity and heat can also be a factor. A humid environment can cause your paper to absorb moisture causing feed problems. If you turn off your heat or air conditioning over a weekend, allow the room temperature to return to normal before you begin working.

The Xerox Fuser Plays a Crucial Role in Creating Professional Documents
This toner, after it is applied to the paper, must be bonded to the paper so that it adheres. This is where the Xerox fuser comes in; it uses heat and pressure to make sure the toner sticks well to the printed page.
Most people have no idea how printers actually work, they just know that they need professional looking documents, diagrams and images in their business. With laser printers that are so frequently used in today's business world, it's good to know a little about how they work. This makes for easier diagnosing of problems when something goes wrong. Put simply, the Xerox fuser is the final stage of the printing process - the page passes through this fuser after going through the initial steps of printing, where toner is arranged on the paper.
What does a Xerox fuser consist of? Generally, a fuser assembly is made of fuser rollers, a pressure roller and a powerful heat lamp; it usually includes a cleaning pad which is meant to clear extra or excess toner from the fuser rollers. During the printing process, the heat lamp is directed at the paper as it passes quickly through the fuser rollers. The paper is normally heated to a temperature of 300 degrees or above, as amazing as it sounds. The pressure roller presses down on fuser rollers to assist in setting the print on the page so that it doesn't smear.
The main benefit of a Xerox fuser is its ability to melt the toner and seal it permanently to the page, which creates long lasting documents and prevents smearing of the toner. Fuser parts generally print an average of 150,000 pages before needing maintenance or replacement. It is recommended that you replace your Xerox fuser with the same model when the time comes, to extend the life of your printer and ensure that your documents always appear crisp and professional in appearance.
