[Office Partner Information Center] Ribbon is a kind of printing consumable that we are familiar with. From the earliest mechanically impacted English printers to the later computerized dot matrix printers, the ribbons were used. What should you pay attention to during the use of the ribbon?
Ribbon Usage Tips Things to Note When Using Ribbon
1. What should I pay attention to when using ribbon?
a) The ribbon installation should be very reasonable. If it is unreasonable, then the ribbon on both sides of the print head will be reversed, twisted, and deflected when rotating, which will cause the print needle to directly contact the word roller and wear the print needle, resulting in broken needles and the like.
b) Do not use inferior ribbons, use inferior ribbon cassettes and ribbons. In the printing process, because the cover of the inferior ribbon is not tightly coupled with the box, it is easy to cause the driven gear to move out of position. The main gear does not bite tightly, making the ribbon slack. Due to the poor quality of the ribbon used, the ribbon ink enters the print head stitch along the guide hole of the print pin and solidifies, which causes the needle head resistance to increase, which may cause broken needles or crush the parallel grooves of the print needle, which is more serious. This will cause the print pin driver chip or the ribbon motor and the driver chip to burn out.
2, the skill of extending the needle to the ribbon
In fact, as just mentioned, the ribbon is the main consumable of the dot matrix printer, then we have no way to lengthen the ribbon life in daily use, the answer is yes. You can introduce several ways to save the ribbon. Of course, other printers can be used for reference.
a) Prepare two print ribbon cartridges and print the official document with a darker (newly changed) ribbon. Use a lighter color (used, but the base must be intact, otherwise it will damage the needle) ) The ribbon prints an informal paper or wax paper.
b) Fix two small pieces of foam with transparent tape in the ribbon exit position of the ribbon cassette, sandwich the ribbon between the two foams, and let the foam absorb some good quality printing ink, so as to keep the ribbon moist. , extend the use of the ribbon.
c) Using two foams with better quality printing ink, hold a strip of ribbon exposed at the front of the ribbon cartridge, gently rotate the ribbon shaft, and add some ribbons that have been used for a while (with a good base). Ink (the whole ribbon should be added, otherwise the color will be different when printing), then open the ribbon box and let the inked ribbon cool (or add a small amount of gasoline in the ink). Try it first. The page informally distributes the ink evenly. Print the official draft again.
d) Develop the habit of adjusting the distance between the print head and the paper according to the thickness of the paper. The principle is that it can be large and large, as long as the printing effect is satisfactory. For new ribbons, you can also adjust the distance when printing thin paper, because the color is thicker to ensure print quality.
e) Remove the ribbon when printing wax paper. At this time, do not directly print the wax paper to prevent the wax from melting into the pinhole. Most wax papers are provided with transparent paper, which can be printed on wax paper.
f) Sometimes the printing ribbon cassette is not working properly, and the printing pin repeatedly prints a certain part of the ribbon, causing the color to have a "hole". At this time, the ribbon cassette should be opened first to check whether the gear and the metal card are in series (large Part of it is caused by the card card is too loose). For the damaged ribbon, the hole portion can be cut off and then "welded". The "welding" method is simple: align the interfaces and slightly overlap them, and stick them with transparent thin tape on the inside (note: on the inside). If you are afraid of breaking, you can use the thin lines in the left and right directions at the upper and lower interfaces. Needle (usually only the middle section of the ribbon). According to the quality of the ribbon and the specific conditions after printing, I have adopted the above method, which usually increases the usage time of one ribbon by 1.5 to 2.5 times, which greatly reduces the consumption of the ribbon.
3, ribbon failure and solution
When using a dot matrix printer, the most common is ribbon failure, which introduces and resolves several printer ribbon failures.
a) Ribbon drive wheel drive belt wear or break This fault is caused by the drive belt being used for too long or the character chain friction drive belt. The solution is to adjust the position of the character chain so that it does not rub the drive belt; if it has been broken, please replace it.
b) The ribbon is jammed – the edge of the ribbon is unthreaded, and the ribbon pulley is easily entangled after fluffing, causing the ribbon wheel to be jammed, and the ribbon cannot be properly retracted into the ribbon cartridge. The solution is: first open the printer cover, open the ribbon arm and the hammer row interlocking handle, gently pull the ribbon back at the tape end of the ribbon cartridge, and then interlock the ribbon arm with the hammer row. The handle, turn on the power, the ribbon will be loaded back into the ribbon cartridge after the machine is self-tested.
c) Ribbon motion sensing signal interruption First check if the ribbon motion sensing signal line is damaged. If it breaks, please replace the signal line; then check if the ribbon motion sensing signal line at the J6 socket on the interlocking conversion board is damaged. Or the contact is not good, please replace or plug in the signal line.
d) Ribbon breakage - The tension of the ribbon is too large, and the broken stitch or the hammer is broken to cause the ribbon to break. In the former case, the broken portion can be cut off and re-sealed; in the latter case, the ribbon can be replaced.
In addition, in the process of using the ribbon, we should also pay attention to the installation, use time, proper maintenance, the specific methods and steps are as follows:
a) Before installing the ribbon, the gear should be rotated a few times in the specified direction. After the ribbon is installed, it needs to be rotated a few more times to check whether the ribbon is installed properly, and whether the core is working properly, otherwise the phenomenon of smashing belt is easy to occur. .
b) Low-density core is suitable for 9-pin printers. Under normal circumstances, do not use for 24-pin printers, otherwise the ribbon life will be greatly shortened.
c) Do not print continuously for a long time, so as not to affect the printer and ribbon life.
d) The print head should be maintained frequently. After one month of use, it should be removed and cleaned with 99% alcohol. If the prints are different, check the print head for wear.
Let me introduce you to a new generation of caulking gun-siligun, which is the first caulking gun with shaft-less design.
The compact design allows you to apply it in any narrow space. Most of its parts are made of plastic, which makes it lighter than other traditional caulking guns. Siligun Caulk Gun is convenient to carry around, the hook on the top can satisfy you during construction, hang it on your waist or any other position.
