The color laser printer prints unclear what s going on

For inkjet printers, there can be two reasons: the cartridge runs out, the printer is not used for a long time, or the nozzle is clogged due to direct sunlight. The solution is to replace the ink cartridge with a new one or fill the ink, if the ink cartridge is not used up, it can be concluded that the nozzle is blocked: remove the ink cartridge (for printers where the cartridge nozzle is not one, you need to remove the nozzle), soak the nozzle in warm water for a while, be careful not to immerse the circuit board part in water, otherwise the consequences will be unimaginable.

For dot matrix printers, there may be several reasons: the printing ribbon is used for too long; The print head has not been cleaned for a long time, and there are too many dirt; The print head has a broken needle; The printhead drive circuit is faulty. The solution is to adjust the spacing between the print head and the print roller first, the fault can not be eliminated, you can change the ribbon, if it still doesn't work, you need to clean the print head.

The method is: remove the two fixing screws on the print head, take off the print head, use a needle or a small hook to remove the dirt before and after the print head, generally the ribbon fiber accumulated for a long time, etc., and then drop a few drops of instrument oil on the back of the print head where the needle can be seen, in order to remove some dirt, do not install the ribbon empty a few pieces of paper, and then install the ribbon, so that the problem can be basically solved, if the print head is broken or the drive circuit problem, you can only replace the print needle or drive tube.

Less toner in the toner cartridge, low developing voltage on the developing roller, or unpolarized and charged toner that cannot be transferred to the drum will result in poor handwriting.

Method: 1. Take out the toner cartridge and shake it gently, if the printing effect does not improve, the toner cartridge should be replaced or professional maintenance personnel should be asked to deal with it.

2. In addition, some printers have a switch under the toner cartridge to adjust the intensity of the laser so that it matches the light sensitivity of the toner well. If this switch is not set correctly, it will also cause the printed handwriting to be too thin.

Isn't it powdered? If not, calibrate it. If it still doesn't work, it may be a problem with the laser, so take off the computer and print directly on the printer to see.

Laser printer printing is not clear reason:1. Toner cartridge problem (insufficient powder, aging or numbness of toner cartridge accessories) 2. Laser problem (laser dirty).

3. Fixing part (fusing film is worn or damaged).

Solution: 1. Replace the toner cartridge (80% is the problem of the toner cartridge) 2. Clean the laser (the environment is relatively poor or will not be cleaned for a long time) 3. Print according to the printer, turn off the printer when the paper goes under the toner cartridge, and see if the effect under the toner cartridge will be faint, if it is normal to not go to the fixing, and the fixing will be blurry, it is a problem with the fixing film.

Introduction to Laser Printers:Laser printers were born out of the laser photo-dusting technology in the late 80s and became popular in the mid-90s. It is a printout device that combines laser scanning technology and electrophotographic technology.

Its basic working principle is the binary data information transmitted by the computer, which is converted into a signal by the controller, and then converted into a laser driving signal by the interface control system, and then the laser scanning system produces a laser Hengling Zen beam containing character information, and finally the laser beam is imaged and transferred to paper by the electrophotographic system.

1. For inkjet printing BAI machine, there may be two reasons:

The nozzle is clogged due to the exhaustion of ink cartridges, the printer is not used for a long time, or direct sunlight. dao

The solution is to replace the cartridge with a new one or refill the ink if the cartridge is not used up.

You can conclude that the nozzle is clogged: remove the ink cartridge (for printers where the nozzle is not one, you need to remove the nozzle), soak the nozzle in warm water for a while, and be careful not to soak the circuit board part in water, otherwise the consequences will be unimaginable.

2. For the dot type to talk about the printing machine.

There may be several reasons for this:

1) The printing ribbon is used for too long;

2) The print head has not been cleaned for a long time, and there are too many dirt;

3) There is a broken needle in the print head;

4) The print head drive circuit is faulty.

3. The solution is to adjust the spacing between the print head and the print roller, the fault can not be eliminated, you can replace the ribbon, if it is not good, you need to clean the print head.

The method is: remove the two fixing screws on the print head, take off the print head, use a needle or a small hook to remove the dirt before and after the print head, generally the ribbon fiber accumulated for a long time, etc., and then drop a few drops of instrument oil on the back of the print head where the needle can be seen, in order to remove some dirt, do not install the ribbon empty a few pieces of paper, and then install the ribbon, so that the problem can be basically solved, if the print head is broken or the drive circuit problem, you can only replace the print needle or drive tube.

It is the ink that is not buried enough to cause the ink to fade, and there are two situations in this situation, one is a single cartridge printer, and the other is a double cartridge printer. The most fundamental way to solve this problem is to add ink, and the messenger takes off the ink cartridge and puts the tip of the ink sedan water bottle with a pointed mouth into the ink filling port of the printer cartridge to add good ink. Then check the print quality.

There are two conditions that must be met for printing black and white documents on the color printing machine: The original must be black. If not, you need to remove the color.

After removing the color, check whether the black color of the J Jian backup file meets the requirements. The printer needs to be set to "grayscale" (or black and white) to print the print mode. You can't use the color print mode.

Laser printer printing is not clear divided into the following situations:

1.The laser marking pattern is not clear locally; It is due to the uneven thickness of the medium, the uneven molding pressure, or the uneven temperature, and the insufficient adjustment accuracy of the machine; The general laser processing process control requires the marking error to be within a millimeter, the hardness is kept at about 230n mm, and the surface pattern marking is marked by a certain laser beam.

2.The laser marking pattern is dull and unclear; It should be considered to focus on the topic and the material topic, the laser marking machine also has high requirements for the material, if the material in the marking range, will be back to this situation, mainly some materials themselves reflect the effect of dim; Or because the laser focus is not accurate, just like taking pictures with a camera, the focal length is not accurate, and the ** shot is of course unclear; In the same way, both the laser beam and the camera need to adjust the focal length.

3.The marking pattern effect is whitish; This also has a lot to do with the material, and the solution can refer to the second article.

4.There will be a gap between the marking pattern and the actual setting, this depends on the adjustment of the machine, the marking is to evaporate the surface of the medium through the beam, if there is a gap in the beam itself, it can only be adjusted to the machine first, and the adjustment sheet can be used to correct the vibration mirror and other parts when adjusting the laser beam.

1. Possible causes:

1. Toner cartridge problem (insufficient powder, aging or numbness of toner cartridge accessories) 2. Laser problem (laser dirty).

3. Fixing part (fusing film is worn or damaged).

Second, the solution:

1. Replace the toner cartridge (80% is the toner cartridge problem).

2. Clean the laser (the environment is relatively poor or it will not be cleaned for a long time) 3. Print according to the printer, turn off the printer when the paper goes to the bottom of the toner cartridge, and see if the effect under the toner cartridge will be light.

Laser printer printing** is not clear, how to adjust your good dear, the operation steps are as follows; 1) The printing ribbon is used for too long; 2. The print head has not been cleaned for a long time, there are too many dirt, and the print head has broken needles. 3. The print head drive circuit is faulty.

Solution: 1. Adjust the spacing between the print head and the printing roller first, the fault can not be eliminated, and the ribbon can be replaced with a new one. If the sail is not enough, it is necessary to clean the print head.

The method is: a. Remove the two fixing screws on the print head and take off the print head. b. Use a needle or small hook to remove the dirt mixed in front and back of the print head, which is generally the ribbon fiber accumulated for a long time.

c. Then drop a few drops of instrument oil on the back of the visible needle of the state acacia print head to remove some dirt, and make a few pieces of paper without the ribbon, and then install the ribbon, so that the problem can be basically solved. 2. If the print head is broken or the driving circuit is wrong, the printing needle or drive tube can only be replaced. I hope my answer is helpful to you, and finally I wish you good health and a happy mood!
