What Causes Paper Jams in Copiers and Laser Printers and How to Fix Them

Some types of paper jams can be quickly and easily fixed without calling a technician. This article tells how to repair many types of paper jamming in laser printers and copiers.

When a copier or laser printer's control panel declares, "paper jam" and there's not a single piece of paper anywhere in the printer, you're left wondering where's the paper jam. After the machine commands a piece of paper to be sent from the paper tray it expects the paper to arrive at a sensor within a specific time. If the paper doesn't arrive, the machine assumes it got jammed somewhere along the paper path, and it announces "paper jam."

If you frequently have "paper jam" messages without any paper in the paper path, you've probably got a worn out or dirty pickup roller. The location of the pickup roller is usually directly above the paper tray, in the middle. Grab a flashlight and take a look at it. Feel it to see if there's any texture left on it or if it's all smooth and worn feeling. Try cleaning it first, with a slightly damp cloth, but don't leave it wet.

If cleaning doesn't help, replacement pickup rollers are usually easy to install (there are some exceptions) and are inexpensive.

Most HP LaserJets display the error code 13 for paper jams. In newer printers this is expanded to 13.0 or 13.1 or 13.2. The number after the decimal point refers to which sensor detected the jam. It starts with 0 at the paper pickup area, so a 13.0 message means the paper never arrived at the first sensor. The rest of the numbers are helpful if you know how many sensors your printer has and where they are. Printers usually have three or four sensors in their paper path, with the last one at paper exit, or at the fuser if there's a straight path from the fuser to the exit. There's usually one at every bend in the paper path.

If you get a paper jam at the same location every time you try to print, you've either got some sort of obstruction or you've got a bad sensor. Field technicians have a saying, "the leading edge points to the problem." This means where the first edge of the first piece of paper stops is the area where the problem is located. The problem is either a bad sensor or some physical blockage of the paper path.

Older sensors are usually "flags," pieces of plastic which get pushed down by the passing paper. Flags are designed to pivot and have springs. These can fail in many ways, but it's not uncommon for a flag to just get stuck and it may need only gentle manipulation.

The other type of sensor is optical - the paper breaks a light beam. These sensors can be very small and very difficult to locate. Other than cleaning them, there's not much you can do with an optical sensor. Time to call a tech.


Tips to Maintaining Your Printer by Yourself

It is easy to forget about your printer as you go about your computing needs. It sits there on your right hand side and springs to life when needed. Or at least it is supposed to. If you do not take a minute or two, a couple of time per week, you may find some interesting words coming out of your mouth when streaks or paper jams occur.

Keep it clean

This is easily said and done. The printer heads are the biggie in this area. Printer heads are definitely prone to clogging. If they are not used on a regular basis, or if they are used at a quick clip, they will clog. Every now and again take out the printer cartridges and give a quick clean with a non-linting cloth or moistened Q-tip. If you do use your printer quite a bit think about all those pieces of paper rolling through the printer. It is unlikely that each and every piece of paper will roll through without a shard or tear coming off the paper. These shards will attach themselves to the rollers or other inconvenient printer elements. It is wise to open up the printer every now and again and give it a quick wipe down with a moistened Q-tip.

Turn off and cover

It may seem like many of these tips involve the printer heads, and they do. The printer heads are the area where most preventable maintenance issues occur. Most people, me included, are prone to turning off the computer but not the printer. This leaves the printer heads exposed to the air and possibly drying out. At the ends of the day turn off the printer at the printer. Not from the power cord but at the printer. This will cover the printer heads. Particularly if you are in a dusty region, or if you have a pet, cover you printer. Dust and hair are killers for a printer.

Use the printer

One of the biggest ways to take care of your printer is to use it. Many people really do not use the printer all that much, myself included. This is a digital age and everything tends to stay on the computer. At least twice a week print something that will use all the printers' workings. A colorful website will do but give it a bit of a workout and most of the other maintenance issues will never arise.


How to Repair Canon Printer

E0D02 error: Ensure your cartridge as well as the attached sender strip is free from moisture and dust. The sender strip is located behind the rubber drive belt and runs horizontally across the machine. Make a regular practice to wipe it with a soft cloth.

Learn some printer etiquette's to avoid above issues:

Keep patience: Don’t give print commands for multiple jobs at a single time, as the printer take the time as per the size of the print job requested earlier.

Use desired paper: Abstain from printing on card stock, photo paper, etc; use only laser jet paper.

Restrict print jobs beyond 50 pages: Don’t over burden your printer. It is advised to print not more than 50 pages in one single go. Avoid too much color ink: Black and white laser printers are the best as they need the least maintenance.
