DAMP PAPER, THE BIG PROBLEM

Damp paper is in fact one of the most common problems that a photocopier (or any device that moves paper) encounters, and can cause a multitude of problems from paper jams to image faults.

If you are experiencing paper jams or image quality problems then your paper is the first thing to check. Paper is manufactured in a controlled environment and is packaged in a moisture resistant packaging, when you open your packet (or ream as it's known) it will absorb any moisture in the air (humidity) like a sponge. The same thing applies to any other types of paper e.g. pre printed material like letterhead paper, envelopes, labels and slips ECT.

Damp paper can be identified by some of the following visible signs.

1. Copy is curled (it does not lie flat).

2. Paper is creased as it exits the machine.

3. Poor copy image.

4. Constant paper jams.

5. Paper feels limp and soft; it may also appear wavy if laid on a flat surface.

You may think that your paper is not damp, but you will be surprised how little the moisture content has to alter for it to become a problem. To check if you paper is at fault follow these simple steps.

1. Open a fresh packet of reasonable quality (cheap paper can often be as bad, even straight from the packet, as the packaging is poor and the paper is usually made of inferior materials) paper.

2. Remove the old paper and replace with the fresh.

3. Make some copies using a blank piece of paper as your original.

4. If you machine passes the paper through without a problem then make some more copies using a printed document.

5. Now return to your original job and continue copying.

NOTE: duplex jobs (double sided) are even more susceptible to damp paper as the paper is passed through the copier twice.

Paper Storage Tips:

1. You should re-evaluate where you store your paper, as this will also have a big effect on your copiers performance. If it is stored in a damp cupboard, back room or near an external entrance then your paper maybe spoiled before it even gets to your copier. Store your paper in a dry, warm and controlled environment.

2. If you are a low volume user (paper stays in you machine for more than a day) then only put a small amount of paper in you copier, enough for the day.

3. Try to reseal the papers outer packaging as this is a moisture barrier and will help keep your paper dry.

4. If you can't reseal the packet then put the remaining paper in a plastic airtight re-sealable bag.

You may find this difficult to achieve, but if you can you will save yourself a lot of work and frustration.

For paper jams and print quality problems first check for damp paper.
 
Image explanation
1.The arrow indicates the direction in which the paper is travelling as it exits the copier.
 
2. The arrow also represents the printed image.
 
3. The fault is any addition to the image other than the solid arrow. In this case the thin black line on the right travelling in the same direction as the paper.

IMPORTANT
1. When dealing with the drum unit be careful not to touch the drums surface with your fingers, and only expose to light for a short period of time (2 mins at a time). If you remove the drum place it in a dry safe place and cover to prevent any light exposure. Prolonged exposure to light will result in permanent damage.
 
2. The fuser section of your machine is extremely hot and should be handled with care. You should turn the machine off and wait for at least 20mins for it to cool down before attempting to touch it.
 
3. DO NOT use any cleaners or solvents on any internal components. Use only a dry lint free cloth to clean and do not use excessive pressure on the drum surface. DO NOT use any tools or objects to assist in any cleaning. IF IN ANY DOUBT CONTACT YOUR LOCAL DEALER.
