Solutions for Laser Printer Common Malfunctions!

Laser printer, as the most common office equipment, brings a lot of efficiency and convenience to our daily life because of its excellent printing quality and effective speed. In contemporary society that time exceeds everything else, laser printer becomes the work necessities of the professionals. It seems that laser printer works simply, however you will be at a loss if it is on strike at a critical time. If laser printer breaks down, the first solution occurs to us is to ask help from the technician. In the process of waiting for help, a mass of valuable time is wasted. Have you considered repairing your laser printer by yourself? Actually most of the printer malfunctions result from our misoperation or careless maintenance. Now we will teach you several tips in case of the printer problems. Then we could do it yourself and easily address both the symptoms and root cause.

We have classified the malfunctions into several types and display the relative solutions each.  

 

First, outline letters problem:

 

1. the paper is too stiff and too thick; we advise you to change the paper to be the thin one.

 

2. the paper is set in the opposite way, please change.

 

3. the paper surface is too smooth and change into the rough.

 

4. the film is not up to standard, please change into the laser film.

 

5. the paper is damp and change into the dry one.

 

6. the carbon powder is in low quality and change into the better one.

 

Second, the color of the printing paper is too shallow:

 

1. organic photo conductor drum is too old and change into a better one.

 

2. mag roller is worn out, please repair or change.

 

3. transfer roller is contaminated or aged, please clean or change.

 

4. power roller is worn out, please change.

 

5. the carbon powder is too bad or incompatible, please change.

 

Third, there are vertical stripes on the printing paper:

 

1 .mag roller is scratched when it is connected with other components; or just because the squeegee bears so much burden that it rubs the surface of the mag roller.

 

2. the edge of the squeegee is not sharp or the accumulated powder is too much.

 

3. the carbon powder can not be displayed equably or in the way of stripe displayed 

 

on the develop roller.

 

4. there is stripped carbon powder dung on the mag roller.

 

5. it is jammed in the entrance of the juser.

 

6. the heat roller is jammed with carbon powder or other dirt.

 

7. the organic photo conductor drum is seriously scratched, therefore it can not affix the carbon powder.

 

8. there is dirt on the wire electrode of the charging set which results in the organic photo conductor drum not being charged, therefore there will be some white strips.

 

9. the voltage is too low to charge equably, so there appears some white strips with different width and vague fringe.

 

10.transfer electrode is too dirty to normally transfer print.

 

11. the carbon powder is few as well as the separation claw is transformed.

 

Forth, totally white or totally black images:

 

1. control circuit or scan circuit breaks down;

 

2. laser or laser control circuit is damaged;

 

3. optical system is sheltered or the reflector is too dirty or too old;

 

4. scan driver has circuit malfunctions which disables to scan.

 

5. the electrode of the charging set is damaged or the electrode wire is broken;

 

6. the gear wheel can not take the organic photo conductor drum to rotate because the wheel can not rotate well.

 

Fifth, dirty images:

 

1. the surface of the organic photo conductor drum is scratched or contaminated.

 

2. there is solid carbon powder on the develop roller which result in super-adsorption capacity.

 

3. the cleaning devices of the organic photo conductor drum are damaged.

 

4. the transfer electrode or the electrode of the charging set is unbalanced.

 

5. the pickup roller is polluted by the carbon powder.

 

Sixth, white spots on the black images:

 

1. the emulsion layer of the organic photo conductor drum peels off.

 

2. there is impurity in the carbon powder.

 

3. the electric tension is too high to breakthrough the organic photo conductor drum.

 

Seventh, the back of the printing paper is polluted:

 

1. the carbon powder of the develop roller or the cleaner is leaked on the paper.

 

To sump up, all the malfunctions above result from careless cleanning of the printer components. Therefore we will solve most of the problems if we often use a piece of cotton with alcohol to scrub the surface of the printer. However, if there are some problems related with circuit board or hardware, it is better to consult the professional maintenance personnel.
