Introduction: as early as the 1970s of the last century, Epson began the research of piezoelectric technology, after nearly 20 years, and finally succeeded in applying the micro-piezoelectric printing technology in the field of printers to achieve productization. The so-called continuous inkjet is to produce ink drops in a continuous manner regardless of the printing pattern or non-printing pattern, and then recycle or disperse the non-printing ink drops. However, this technology is almost a drop of ink spots printed on paper, the effect of the poor can be imagined, so in reality there is no practical value.
What are the tips for printer maintenance
One: Maintenance of inkjet printers
Inkjet printers are increasingly becoming the object of choice for home printers because of their good color document output and low initial acquisition cost. As a "master" of such a product line in-depth? The author on the last few years? Intimate contact? The experience gained, the following to introduce some of the daily use of inkjet printers in the process should pay attention to the maintenance of matters as well as on the printer ink consumption is too fast a problem.
First, the daily use of precautions
1. Must ensure that the printer in a solid level of work, do not place any items in the top of the printer. The printer must close its front cover when printing to prevent dust or other hard objects from entering the machine to impede the movement of the printer carriage and cause unnecessary failure. If you open two cartridges at the same time (a black cartridge, a color cartridge) should be one of the cartridges into the cartridge box supplied. It is prohibited to plug and unplug the print cable, which will damage the printer's print port as well as the PC's parallel port, and in serious cases, it may even break the PC's motherboard.
2. Keep the environment clean. The use of environmental dust is too much, easy to cause the word car guide shaft lubrication is not good, so that the movement of the print head in the printing process is blocked, resulting in inaccurate print position or impact on the mechanical frame caused by the crash. Sometimes, this dead due to the print head did not return to the initial position, in the reboot, the printer first let the print head to return to the initial position, followed by cleaning the print head operation, so causing unnecessary waste of ink. To solve this problem ` method is to often wipe off the dust on the guide shaft, and the guide shaft lubrication (choose a better fluidity of the lubricant, such as sewing machine oil).
3. If the printout is not very clear, there are stripes or other defects, the printer can be used to clean the print head of the auto-cleaning function, but need to consume a small amount of ink. If the print is still unsatisfactory after several consecutive cleaning, the ink may have been used up and need to replace the ink cartridge.
4. Before shutting down, let the print head back to the initial position (the printer in the pause state, the print head automatically return to the initial position). Some printers automatically move the print head to the initial position before shutting down, some printers must be in the shutdown to confirm that in the pause state (i.e., pause light or PAUSE light is on) before you can shut down. This is to avoid the next boot when the printer to clean the print head operation waste of ink; two because the print head in the initial position can be sealed by the protective cover, so that the printhead is not easy to clog.
5. Some printers are mechanically locked in the initial position. At this time, if you move the print head by hand, will not be able to make it leave the initial position. Be careful not to forcefully move the print head, otherwise it will cause damage to the mechanical parts of the printer.
6. When replacing the cartridge, be sure to follow the steps in the operation manual, and pay special attention to the power on the state of the above operations. Because of the re-replacement of the cartridge, the printer will be on the ink delivery system to fill the ink, and this process will not be carried out in the state of power off, the printer can not detect the re-installed on the cartridge. In addition, some printers on the ink capacity of the measurement is to use the printer's internal electronic counter to count (especially in the color ink usage statistics), when the counter reaches a certain value, the printer to determine the exhaustion of ink. During the cartridge replacement process, the printer will reset its internal electronic counter to confirm that a new cartridge is installed.
7. When plugging in the printer's power cord and print cables, it is important to power down the printer as much as possible, especially if you are using an old parallel port with a computer.
Second, the printhead ink maintenance related matters
1. Inkjet ink has a conductive, if spilled on the circuit board should be wiped with anhydrous alcohol, dry and then powered on, otherwise it will damage the circuit components.
2. Do not disassemble the printhead with electricity, do not place the printhead in a place prone to static electricity, take the printhead should hold its metal parts, so as to avoid damage to the internal circuitry of the printhead due to static electricity.
3. Ink cartridges are not used up, it is best not to remove, so as not to cause a waste of ink or printer ink metering errors. At the same time it should be placed at room temperature to avoid direct sunlight when not in use for a long time.
4. Do not use the mouth directly to the nozzle or other ink pipeline blowing, in order to prevent saliva contamination inside the pipeline and affect the smooth flow of ink.
5. Inkjet printers should be used in a cleaner air environment, especially should be targeted to prevent rodent damage, to avoid its bite through the ink lines.
6. Some printers have temperature restrictions on the use of ink, in the specified temperature range can play the best performance of the ink. For example, Canon BJ printer ink for the use of temperature -10 ° C to +35 ° C, when the ambient temperature is below -10 ° C, the printer ink may freeze; when the ambient temperature is 35 ° C or more, may also affect the chemical stability of the ink.
Three countermeasures against rapid ink consumption
Correct use and maintenance can avoid inkjet printer cartridge ink consumption too fast. The rapid consumption of ink cartridge ink may be caused by the following incorrect operation:
1. Failure to turn off the printer by pressing the power (POWER) button.
2. Frequently turning off the printer by unplugging the power cord from the outlet.
3. Forcefully turning off the printer while it is printing. Turning off the printer while the print head is at rest or in the initial position cap state.
As long as the above few bad habits are effectively overcome, then in the future it will make? You? s ink will last longer.
2: Maintenance of the pin printer
1, do not touch the surface of the print pin with your fingers. After the printer has been used for a period of time, use anhydrous alcohol to scrub the print head to ensure that the guide hole is unobstructed.
2, regularly use a small brush and vacuum cleaner to clean up the dust and paper dust inside the machine.
3, the position of the print head should be adjusted according to the thickness of the paper.
4, if you find that the ribbon is broken, be sure to replace the ribbon with a new one immediately. Do not use broken ribbon, or there is a risk of needle breakage.
5, if you find the walking paper and needle trolley running difficulties, do not use your hands to force the movement, we must find out the cause and deal with it in a timely manner, otherwise it is easy to damage the mechanical parts and circuits.
Three: Laser printer maintenance
As the printer's internal components are more sophisticated, even ordinary wipe or add lubricant may be able to print the quality of the image can not be underestimated, so the internal cleanup must be cautious and careful:
1. Toner protection: the printer's cartridges will have some pads, their role is to absorb excess toner in the roller system that transfers the paper. Users can remove it from the machine and clean it manually. A new liner is usually included in a new cartridge as well.
2. Feed rollers: they are the transport part of the printer, dragging the paper from the paper slot to the inside of the printer, but in the process, the oil and dust that tarnish the paper will also settle on the rollers, and a long period of time without cleaning will lead to paper jams and misfeeds, which are the most prone to failures in the printer. Here, we can use alcohol-soaked cotton balls or a damp cloth to clean these deposits. In addition, there are special roller cleaners available at some office equipment specialty supply stores.
3. Crown wires: They are specialized wires that are used inside the printer to transmit static electricity. Static electricity is used to attract toner to the paper, but dust deposits will affect the efficiency of the use of static electricity (especially for some of the older laser printers particularly serious impact). Users can use a cotton cloth to gently wipe away the dust, but please do not use alcohol or other solvents, they will affect the effectiveness of the printer, usually in the old laser printer, the crown wire inside the printer is bare. If you can't find them, the printer manual indicates where they are located.
4. Vents: Similar to the inside of a computer, many laser printers have internal fans that can get clogged with dust and dirt from years of work. We must ensure that we clean the vents and fan pages regularly to keep the air flowing inside the printer.
Cleaning the outside of the printer is generally easier and safer than cleaning the inside. The average user can use the same cleaning/protection spray used to clean the interior of a car to clean the exterior surfaces of computer hardware, which can help reduce static electricity and is safer for plastic surfaces. The cleaner can be sprayed on a soft cloth and used to wipe down the casing of the device (taking care not to spray the spray into the interior of the machine), while cleaning the exterior of the printer we can also remove dust and dirt by blowing compressed air through the air outlets, fan passages, and paper slots.
