Common troubles and solutions for inkjet printers

More and more inkjet printers into the ordinary consumer's office or family, to bring you a lot of convenience and fun. But inkjet printer is a high failure rate of the computer peripherals, failure, or will bring a lot of trouble to users.

Understanding the printer's attention to the day-to-day maintenance of the printer will not only reduce the chance of printer failure, but also extend the working life of the printer. The following is the use of inkjet printers frequently occurred in the fault and related parts of the hardware structure description.

Inkjet printer is a common computer peripherals for mechanical electronic integration. The mechanical part includes the feeder, the paper roller, the paper wheel, the print head, the word vehicle assembly, the motor of the word vehicle, the paper motor, the pump, the pump accessory, the circuit part includes the motherboard and the Power board. The printer works by the power supply board +36V/42V used to drive the print head, Word motor, paper motor, +5v for the logic circuit driver. The work of each mechanical part is coordinated by the motherboard according to the computer instruction to produce the control signal.

When the press Enter/Exit key or the printer receives a print command from the computer, paper motor in accordance with the design of the direction of rotation, through the transmission of power transmission to the rubbing paper wheel and cam to make its rotation, cam rotation so that the cardboard in the spring tension in the role of bouncing and rubbing paper wheel contact, The rotating rubbing wheel will be placed on the cardboard paper to use friction to send the paper into the printer's word roll and guide wheel, and continue before, and finally through the paper wheel to send the paper out of the printer, complete the paper-making process. The nozzle sprays the dots at a definite position to form a pattern.

Question 1. Why does the paper go awry when the paper is printed and the paper goes into the printer?

We understand that the basic structure of the printer after the principle of this problem for the printer is good analysis, there may be the following reasons:

(1) The printer into the paper frame fell into foreign bodies.

Countermeasures: The printer to feed, paper, so the foreign body is very easy to fall from these channels into the inside of the printer, so you must pay attention to the use of printers, paper clips, staples, buttons, rubber bands are easy to fall into the inside of the printer things.

(2) The surface of the printing paper is too smooth or easy to lose fiber powder. Countermeasures: Some of the printed paper quality is poor, coupled with the use of some users poor environment. Printer after a period of time, rubbing paper wheel surface area to leave confetti and dust, so that the strength of rubbing paper, causing slippage, there is no paper or paper into the phenomenon of skew. Therefore, we suggest that you do not covet cheap paper as far as possible quality of paper, in addition to the printer a cleaner use of the environment.

(3) Two-wheel feeder printer when the retention structure of one of the rollers is loose, the paper loses its function and causes the paper to be incorrect.

Countermeasures: Take care of the printer lightly, do not use too thick paper.

(4) The movable cardboard on the paper frame is too far away from the edge of the paper, making the amplitude of the paper swinging.

Countermeasures: Simple, the use of how much paper, the active baffle adjustment to how large.

Question 2. Why does the printer use a time after the printer is often inhaled paper after the paper does not move and only print head back and forth?

It is possible to rub paper wheel rubbing paper ability to drop, resulting in the paper is not in place, paper can not reach the word roll, can not continue to go forward, so that there is no movement of printed papers and only the print head moving back and forth. Countermeasures: can refer to the above problem solution.
Question 3. Does the printing head run after the printer is powered on, why some time is long, some time is short?

The printer will run after the start of the printing head to consume a certain amount of ink, the length of time by the motherboard on the timer circuit decision. After the printer is turned off, the circuit by a button battery power to calculate how long the machine has not been used, in the next boot, the printer based on the circuit provided two times the time data, to determine the length of the printer cleaning time, long time not to clean the printer longer. Countermeasures: Do not want to "save" without the printer, printer for a long time, will cause the print head blocked, running parts abnormal, the printer will really be "put bad". If there is no print task, it is best to open the printer every two or three days, dash the print head.

Question 4. Ink box in how the ink is sucked through the pump attachment to the inside of the printer, printing blurred or no print traces, after cleaning the situation is worse, whether with the pump attachment adsorption capacity?

The printer executes the pump ink instruction, the print head moves to the original position, at this time the pump accessory seals the print head nozzle, causes it to insulate with the outside air. At the same time, paper motor driving the pump wheel rotation, so that the ink inking tube produced negative pressure, the ink cartridge into the print head and pump accessories, the release of the sealing state, the pump will continue to rotate the pump attachment in the ink suction waste ink pad. If the printing blurred or no print traces, after cleaning the situation worse, may be related to the pump accessories. Countermeasures: No way, to repair.

Question 5. Does the printout of the ink leak indicate that the nozzle is faulty?

Generally due to uneven printing paper or a foreign body on the print head, often in the printing will rub on the paper, and nozzle-independent. Countermeasures: Note the use of printed paper quality, do not use the ink without quality assurance.

Question 6. How does the printer clean the print head?

Countermeasures: Need to clarify a concept, cleaning the print head, is actually cleaning the nozzle on the print head. If the nozzle has a slight blockage, the application tool in the software can use the software method to call the printer's own cleaning nozzle function. If the nozzle blockage is serious, the software method is invalid, can send to the manufacturer's repair station maintenance, the engineer will remove the print head to use a special cleaning liquid box ink cleaning.

Question 7. Why does the printer have a sliding seat error, or even the print head bump head phenomenon?

Printer guide and Word conductor time use or because of the poor use of the environment, will cause the word Car guide dirt and wear, increase the movement resistance, when the resistance increases to a certain extent, the motor traction can not normally drive the word car movement will produce abnormal word, bump the head phenomenon. Countermeasures: daily use to maintain a clean environment, if found that the word Car guide surface dirty should be clean and add a little lubricant.

Question 8. Printer and computer normal connection, the computer has been connected to the printer power button is not connected, why in the printer power cord plugged into the strip, the printer and the mouth burned, the computer can not work properly?

The connecting port connection does not support hot plug, and this failure is not related to the printer hardware. Countermeasures: When using the same port to connect to the printer, it is best not to live on the computer side of the mouth.

Question 9. Why the printer used for a long time, the original is also normal use, suddenly the printer led flashing, the printer does not work?

Inkjet printer has a waste ink pad, its role is to absorb the printing head when cleaning the waste ink. Printer Each of the different forms of shampoo consumption of ink is not the same, specifically by the motherboard control, the counter will be cleaned each print head consumption of ink (that is, waste ink) accumulation. When the counter accumulated amount of waste ink reached the upper limit, the printer will stop working, to prevent the waste ink pad after ink dripping ink into the printer inside damaged. Countermeasures: If your printing is particularly large, you should be aware that the printer may use 20 ink cartridges, the printer might appear this problem. If this problem occurs, it is best to send the printer to the repair station to replace a new waste ink pad, and the waste ink counter clear zero.
