How to solve the problem that the color printing of the printer is not clear, and the black and whit

The printhead needs to be cleaned up, see if there is an option in the printer preferences to clean the printhead.

The print head is blocked, what is the specific model??? It can be washed.

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.

I'm still a little confused, can you be more detailed?

1. The printer slag answer has not been used for a long time, resulting in the ink delivery system obstruction or the blockage of the printhead. Printhead cleaning can be performed directly on the printer. 2. The printer nozzle enters the air, and an air bag is formed in the nozzle part, so the ink cannot be printed, the print head is cleaned first, and the nozzle is generally checked for 5-10 minutes, and repeated about 3 times.

3. The printer printhead is blocked. Perform the cleaning operation directly on the printer. 4. The printer ink is insufficient, if the printer is not enough black water, then add the ink directly.

5. If the ink cartridge is not in good contact and the ink is not produced, the ink cartridge can be removed and reinstalled again. 6. The printing paper is not placed correctly, such as Chunhui suggests putting the printing paper flat or cleaning the place where the printing paper is placed. 7. Not printed completely.

Put the paper in the printer and wait for a certain amount of time before taking it out.
