Basic question and answer for inkjet printers

Q: What is the difference between ink cartridges, ink cartridges, print heads, and inkjet heads? A: The inkjet head is the print head, which is the main component of the inkjet printer. The ink cartridge is used to hold the ink, and the print head and the ink cartridge are together called the ink cartridge. Note: The one-piece cartridge is the print head and the ink cartridge. When the ink is used up, the entire cartridge needs to be replaced. The separate ink cartridges are separated from the print heads. When the ink is used up, only the ink cartridges need to be replaced. The printing cost is lower. Q: When we read the printer's data, we often see English abbreviations such as DPI, CPI, and CPL. How do you explain this? A: CPI: Characters Per Inch abbreviation, the number of characters contained in each inch, used to indicate the size of the character, spacing; CPS: Characters Second Abbreviation, the number of characters per second can be printed, used to represent the printer The print speed. Of course, it is related to the size of the printed characters. Generally, the printing speed is calculated based on the 10CPI Spanish characters. PPM: Abbreviation of Paper Per Minute, the number of pages printed per minute, another way of expressing the print speed. DPI: an acronym for Dot Per Inch, the number of dots or lines printed per inch, used to indicate the printer's print resolution. This is one of the main factors in measuring the accuracy of the printer. In general, the larger the value, the higher the printing accuracy of the printer. Q: Why did my inkjet printer print normally yesterday and I can't print it today? A: Under normal circumstances, no ink can be printed. There may be two situations: 1. The print head needs to be cleaned 2. The ink is used up. Generally, the print head is cleaned. The printer itself has the function of cleaning the print head. Do not print on the outside of the printer. The print head is used for wiping and other operations to avoid damage to the print head. For specific cleaning methods, since the printers are not the same, refer to the corresponding section in the user manual. If you still print after three times of cleaning, it may be that the ink has run out and you can replace the new ink tank. Q: Why does my cartridge sometimes leak ink from the nozzle? Answer: Because the ink cartridge is composed of a print head and ink, and the ink is stored in the sponge, there is a vent on the outside to maintain the same atmospheric pressure. When the temperature changes rapidly, an abnormality occurs. We know that the thermal expansion and contraction of air is much more than that of liquid. When the ink in the cartridge consumes some ink, there is a part of the air in the cartridge. Under normal circumstances, due to the presence of air holes, the air pressure is maintained. Normally, if the temperature suddenly rises, the ink cartridge The air inside suddenly swells, and if the pores are too late to adjust, ink may be discharged from the print head, causing ink leakage. If this happens, simply wipe the ink out carefully, but do not touch the nozzle part. Q: Why is my inkjet printer printing under WINDOWS 95 incomplete? A: In WINDOWS 95, the default option for the print interface is "ECP interface" and must be changed to the normal "printer port". Specific methods can refer to the following steps: Start - Settings - Control Panel - System - Device Management - Port - Printer Port - Driver - Change Driver - Show All Devices - put "ECP Printer After you change to "print port", confirm and restart your computer. For some computers, you also need to change the computer's CMOS settings and change the print interface from "ECP mode" to the standard parallel interface. Q: Why does my printer report a "detected ink cartridge mismatch" during printing? A: In WINDOWS95 - My Computer - Printer - select your printer - Properties - settings in the "detect ink cartridge options" close. Q: Why is the result of my printer's printout compressed horizontally? A: This is caused by improper software settings when you print. If you are using a photo cartridge, you must select "Photo Mode" in the graphics options in the printer properties, otherwise the result is compressed horizontally.
