Fix Your Own Laserjet Printer Fuser Problem

By Edited Jun 28, 2015 0 0

Do you have paper wrinkling problems?

Your laserjet fuser film may be broken.

The HP LaserJet uses a mylar tube in the fuser fixing process. This tube is quite sturdy but is often broken after many years of service. Unfortunately, the tube is installed deep within the printer. The replacement cost is fairly low but the effort to install a new one is significant. Luckily, the people at Fixyourownprinter.com have come up with an easy to follow video guide that shows you exactly how to replace the mylar film. The video comes in a kit with the replacement film and some required grease.

Well over 100 million HP LaserJet printers have been shipped to users around the world. These machines have offered reliable printing since they were introduced in 1984. Based on the Canon laser printer engine, the LaserJet became the primary laser printer model. They were capable of printing excellent quality text documents from the beginning. Because many of the sensitive parts are contained in the print cartridge, many of the complex parts are replaced when a new cartridge is installed. There are, of course, still quite a few parts that are never replaced. Most of these are capable of serving well for many years. Even the fuser film is a long lived part. It operates in a hostile environment, however, and it is only made of thin material. The film can totally split or small pieces can drop off. Often you will find small sections of the fuser film when you look inside the printer. You can also tell that you have trouble when your printer begins to wrinkle the paper.

The video repair guide tells you how to get started with the fuser film repair. The plastic case must be removed first. There are many screws that hold it together. The guide does a good job of showing the locations of all of them. It also shows some tricks that help when performing the repair. Certain screws are only accessible when components are rotated correctly. Others are a little hard to find without help. The video also provides ample warnings that help to avoid lengthy steps during the installation process. Despite this, the repairman in the video actually slips and dislodges a critical piece during a repair. He is forced to perform the numerous steps to recover from his earlier error. This gives the viewer the ability to see how to do the same should they run into the same problem. It also emphasizes just how important it is to avoid making the same mistake.

With the help of the video, a recent fuser film repair was successfully accomplished in about 1.5 hours of work with no prior knowledge of the printer's internals. The old film was removed and found to have large chunks missing. The new fuser film was installed as per the video guide instructions. No parts were leftover. The instructions provided were very accurate. The final installation of the drive gear was more difficult than shown by the video instructions, however. The printer chassis is quite complicated and getting everything to line up can be tricky. There is only one way to get it assembled, however, so with careful positioning of the unit during reassembly, the chassis snaps together when everything is aligned.

After the steps from the repair guide were completed, the printer was turned on. The resulting test pages were perfect with no wrinkling. The LaserJet 1300 had been creasing the bottom of each page. This printer was 6 years old and had never given any trouble. The fuser film repair was about a $35 cost. With the repair made, it is expected to give good service for many more years.
