What’s Wrong With a Straight Commission Sales Job?So you need ten sets of a fifty page document for this mornings meeting. It’s 8:30AM and your meeting is at 9:00AM. You begin with your project and the copier jams. You clear the jam but it keeps jamming! It’s not pulling in the paper. Sure you can call the repair person, but you need the copies now! There’s nothing you can do, or is there?All office equipment that feeds paper has a component inside that pulls the paper out of the paper tray and into the machine. Most are made out of rubber and just like the tires on your car they wear out. When a roller is worn and dirty they will cause paper jams. The purpose of this article is to show you how you can clean or rejuvenate the rollers long enough for you to complete your job and have your repair person come out and fix it properly.Alternative solutionsWhen your machine is jamming, first locate where the paper is jamming. Which paper tray? Is it tray 1 or tray 2? Also which size is jamming? On machines that have more than one paper tray you can switch paper trays and then you can skip cleaning the rollers. Make sure when you change cassettes that the copier registers the correct size. The machine will think it is a different size and it will jam. The sensors are set for a specific timing and it will know the difference in length from letter size and legal size. I also would try using the bypass tray or manual feed tray if so equipped. This will get you up and running quicker than cleaning the rollers.Determining if the rollers are the problem:If you need the specific tray to be functional we will get busy with the repair.First make a single copy in the tray that is jamming. By doing this you are determining where the paper is jamming. If it is jamming in the exit for instance, you have another problem. If it is jamming in the center of the machine, again it is a different problem. But if it jams at the cassette or paper tray area the next step is removing the paper tray. Shine your flashlight into the paper feed area and see if there are any pieces of paper torn off inside or something blocking the paper path. Now that you have ruled out a blocked paper path, you can clean the feed roller(s).Tools Required:Flashlight, strong cotton towel (so it will not rip off in the machine), WD-40 or Rubber roller rejuvenator. Note: Never use alcohol to clean rollers. It dries out the tread and the remaining tread will get ripped off and then it still will not feed. Use WD-40 it works great!Cleaning the rollers:Shine your flashlight into the paper feed area and locate the rubber rollers that feed the paper in. Grab your towel and saturate it with cleaning fluid. This can be WD-40 or your favorite roller rejuvenator. Start by cleaning the roller and spinning it all the way around not missing any of the surfaces of the roller. Then go over it again with the dry part of the towel. As I said there are many different types. Some have a set of three rollers. One Pre-feed roller, this pushes the paper into the other rollers. One feed roller and one separation roller. Others have a half moon style. These are harder to clean because they have a clutch system that keeps it at home position when not feeding.WARNING: If you try and turn these to clean them you will damage the clutch mechanism! There are two ways you can clean these types. First you can actuate the clutch by pushing down on the solenoid or release lever. This sometimes can be hard to get to. You can also start the copy process and shut off the machine exactly when the feed roller engages. This takes some patience and practice but it is better than damaging the clutch. Once you get it where you can clean the roller repeat the procedure above.Some alternatives to replacing feed rollers: There is a material called feed roller tape. I have used it when I didn’t have the right roller in my car stock. It works with some styles mainly half moon styles. Just peel off the adhesive and wrap it around the worn roller surface. They also have some that stretch over the old rollers. I have never used this but I have been told it will get you up and running. On old copiers or printers that you can no longer get parts for you can apply clear silicon on the feed surface and let it dry twenty four hours. It works but I am inclined to use the real thing. You can also use generic rollers manufactured for almost all equipment. I have mixed feeling about these because I have had to go back and change them again later. For the best repair I use genuine OEM feed rollers. They are still inexpensive and they will last you longer and you will have fewer headaches.Feed RollersThere are many types of rollers and feed systems. Here are some common feed rollers with their part numbers. Rollers will normally come in a maintenance kit but they may need to be replaced approximately half way through the maintenance kit cycle.HP LJ-4000 laser printerFeed RollersRG5-2651-000CN x 2Note: These are very easily replaced. Just unsnap them and replace them with the new roller.Toshiba E-Studio 350/450 Photocopier Paper Feed Rollers 44201807000 x2, 4400669910Note: These take a little more work. First you need to remove the paper feed assembly and then you can get to the clips that hold them on.I hope this has helped you complete your print or copy job. Please remember that this article is just a quick fix and not a long term solution. Be sure and call your repair person to fix it correctly.

We now can just walk up to a photocopier machine and press the print button and we instantly receive perfectly replicated copies of our original. Just forty seven years ago the copy machine was a pen and some sheets of carbon paper. Instead of pushing a button you had to write and write and then write some more! Just before the 60’s this was a reality and carbon paper was a big seller. Chester Carlson, a patent attorney knew how much of a pain it was to continue rewriting everything by hand because Carlson had arthritis. Carlson had an idea of designing a machine that would automatically make copies, so he didn’t have to do all of that copying by hand.Think about doing your job without a copier. You probably will have a hard time imagining it. Did you know that most manufacturers didn’t think that a copier would be of much use? Chester tried for years to get people to catch his vision but nobody was interested. Between 1939 and 1944, Carlson got the thumbs down by many corporations, including IBM, Kodak, General Electric, and RCA.In 1937 Chester invented a process called electrophotography. They renamed it Xerography in 1938. He figured out that if the image of an original document was projected onto a photoconductive surface, current would flow only in the areas where the light shined on it. The first copy was made with a sulfur coating on a zinc plate. He took a glass microscope slide and wrote on it 10-22-38 ASTORIA with ink. He then pulled down the shade to darken the room. He built an electrostatic charge buy rubbing the sulfur surface with a handkerchief. Then the slide was placed on the surface and a light was shined on it for few seconds. He then sprinkled lycopodium powder on the sulfur coating. Gently blowing on the surface, the loose powder blew off and all that was left was the inscription, 10-22-38 ASTORIA. 10-22-38 is the date that the first photocopy was made. Astoria was the location.The Birth of Xerox The company that decided to take a chance on Carlson’s dream was the Haloid Company. Haloid was a photo-paper manufacturer in New York. Guess what they came to be known as? Yes, the Xerox Corporation. In 1960 the first office copier was produced. It was the Xerox model 914. It was the first office copier that could make copies on plain paper.Being a copier repairman for over twenty years I have seen the good copiers with the bad copiers. I began working on copiers in 1983. The copiers that I began working with were messy and they would not last long in between servicing. The prices for the machines were very high especially for higher volume copiers. There were some interesting ways of transporting the paper through the machine like the Sharp SF-740. It grabbed the paper with two gripper devices that were driven with chains. This machine fused the toner to the paper with a toaster oven type device.Some people may even remember having to pour toner into the copier from a bottle. But today’s copiers have a cartridge system that works well. They keep most of the toner inside the copier, not on you best pair of slacks or your dress. They have rollers for fusing the toner to the paper and have very sophisticated paper feed and transport systems that help reduce jamming problems. Digital copiers are now on the market. Now you can not only copy, but print, scan and even fax with them. Perhaps the most revolutionary change in the industry is the full color copier. The sales of full color copiers have really started to explode. There are a lot of new and exciting products being introduced and the quality is really quite good. We have come along way from Carlson’s ’10-22-38 ASTORIA. I just can’t help to think what the future will bring us. What will the copier of the year 2020 look like?Chestor F. Carlson (1906-1968). Chester F. Carlson was born on February 8, 1906 in city of Seattle. His father was a barber and they came to live in San Bernardino, California. He was a bright young man and was curious of how things worked. Carlson’s mom died when he was seventeen years old. They say that Carlson donated $100 million to charity before he passed away in 1968.
