Use epson printer ribbon Note:

1. Before installing the ribbon gear should turn a few laps in a predetermined direction, installed after the citizen printer ribbons, also need to sub a few times to check that the ribbon is installed, with a core is working properly, or prone to smash band phenomenon .

2. ribbon ink devices supplemented, when print imprinted slightly lighter when the ribbon should be specified on the ink method (such as the top of the iron sheet, etc.), to replenish the ink, print imprinted back to normal.

3. The low-density tape core is suitable for 9-pin printers, under normal circumstances, not for the 24-pin printer, or ribbon epson life will be shortened.

4. Print not long continuous operation, so as not to affect the printer and ribbon life.

5. The print head should always maintenance, should be used for a month after it is removed with 99% alcohol to clean. The print appears uneven, you should check the print head is worn.

epson printer ribbon Fault and Maintenance

1, breaking the ribbon - a citizen ribbon tension is too large, pull off the sutures or word hammer smashing ribbon cause ribbon rupture. In the former case can be broken part cut, sewn back good; the latter case, as long as you can change the ribbon.

2. ribbon is jammed - off the wire edge ribbon, easily wrapped ribbon round after fluffing led fujitsu printer ribbon round cards, ribbons not properly retract the ribbon cartridge. The solution: First, open the printer cover, turn the ribbon discharge interlock lever arm and hammer open, end ribbon belt ribbon cassette gently back, and then close the arm with the hammer on the ribbon row interlock handle, turn on the power, the machine will be in self-test ribbon Replace the ribbon cartridge.

3, ribbon capstan drive belt worn or broken - this failure is due to drive belt or chain of characters used for too long caused friction drive belt. The solution is to adjust the position of the character chain, it is no longer friction drive belt; already broken, replace it.

4, ribbon motion sensing signal interruption - to check if ribbon motion sensor signal line has been damaged, if broken, replace the signal line; then check the interlock signal conversion board Ribbon motion sensing line at J6 socket whether damaged or not, replace or plugged signal lines.

avoid epson printer ribbon bruising

Periodically clean the print head and the use of high-quality thermal printer ribbon smooth and the backing layer with a film in order to reduce friction; to minimize printhead pressure and temperature of the print; to ensure the IBM printer ribbons is wider than the width of the sticker to prevent exposure to the print head is bruised stickers. After the print head will need to be thermal transfer ribbons contaminated high temperature, high-speed setting value - caused by dirty ribbon backing layer: the accumulation of pollutants in the print head (pin) caused by heat transfer barriers affect print Figure like quality; increasing pollutants cause deterioration in print quality and print objects appear dull and even damage the print (pin). Scratch - Sticker / casing / ribbon through the print head movement will wear long protective ceramic coating layer, the printing scalp (dot) exposure and ultimately damage.

Dot matrix printer and print agency principle

Dot matrix printer and print agency principle
Each print pin is made of a rigid, metallic material toughness is very good, moves back and forth along the guide rail, power from the electromagnetic armature movement forward (forward) to promote and mechanical spring reverse (back) push, when The solenoid coil generates a magnetic field in a given pulse current (corresponding need to print a dot), the solenoid armature moves forward in this magnetic field, pushing the print pin also move forward and strike the ribbon; when the coil After the current disappears, the magnetic field disappeared, the electromagnetic force of the armature lost, mechanical spring reverse thrust to push the needle back to the original printing position. Since a plurality of printing needles can be driven simultaneously, so a single print is a longitudinal array of dots of a character, after the print head moves to the right position of a point, you can print the next point array of characters, after a few Print a complete character; and then control the print head is moved a certain distance to the right, you can start the next printing character, until you have printed all the characters on the line. Next is the paper feed mechanism controls take the paper, the print head back to the left side of the printer, the print process starts the next line of characters.

Some dot matrix printer has its own print buffer memory control logic circuitry. Print control logic is more important font generator, including Western and Chinese character dot-matrix information base; a buffer memory for storing CPU sent to be printed character coding, coding capacity of at least one line of characters can be stored now The printer is usually much more content can be stored; such a relatively small amount of information transferred between the CPU and the printer by encoded characters lattice information to find it is done in the printer control logic circuits and use them pin dot matrix print information control movement. When using dot matrix printer to print graphics, image is, CPU must directly lattice information graphics, images to control the movement of the print needle. Thus, character dot matrix printers and CRT monitor works have much in common, the difference is mainly manifested in: CRT character display using electron beam strikes the phosphor to produce light-emitting point, dot matrix printer is used to produce printing ribbon print needle hit points ; after CRT monitor in full-screen character information to maintain a stable unit continuously scans the display screen, so it needs a display memory VRAM, and dot matrix printer receives a dot column to be printed information and complete the print, these dot matrix information is no longer useful; grating literacy CRT character display, an electron beam across the screen-by-ridden repeat scanning, scanned a plurality of transverse show only complete line of characters, dot matrix printer is the print-by-column mode so print out the dot arrays of characters, several times after printing a complete character.

Dot matrix printer can complete color printing, which uses a color ribbon by the three strips of different colors, and can be in the printing process by moving up and down the ribbon, so that the different colors of thermal printer ribbon bars were under the printhead, which Print out the different colors of the characters. Color dot matrix printer application is relatively small.

The role of institutions is to provide a ribbon of color print source, the ribbon is usually installed in a small disk-shaped box, in the printing process, the oki printer ribbon should keep moving around, driven by the drive mechanism, so that the printing wire comparison uniformly strike the entire ribbon at each position, reducing wear and tear on a local, extended ribbon of use. The print head is a key mechanism for forming the dot matrix printer print-shaped, usually by the vertical arrangement of nine print pins (used for Western print) or 24-pin print (used for Chinese print) of two types. The composition of each print needle device as shown

epson printer ribbon cartridges replacement procedure:
1. Turn the printer off, open the printer's front transparent cover; WARNING: If the printer has been used, the print head may be hot; let it cool before replacing the ribbon cartridge minutes
2. Pull the platen lever, then flips up;
3, the print head moves to the middle of the ribbon cassette for easy replacement;
4, with one hand and hold the ribbon rails, gently pull out until you leave the print head;
5. Hold the ribbon cartridge and the ribbon cartridge out of the printer, the ink ribbon cassette can be removed
6, the ribbon cartridge is installed just the reverse procedure to
Note:
When installing the ribbon cartridge, do not remove the transparent ribbon profile sheet beneath the ribbon guide.
After the ribbon cartridge is installed, turn the ribbon tension knob, so wrinkled uneven ribbon taut to ensure that the ribbon can freely move smoothly.

Cause The printer prints a blank
Document Settings layout is also likely to cause you such a phenomenon, as there are many times in the document added section breaks or page breaks, the surface will each page section break Although only a few pages, you can print each page break will print one blank page, there are more obvious, it is artificially added back many blank pages when you select the entire print will be automatically printed out.

Maintenance Ribbon

Maintenance Ribbon
1, so that the printer ribbon"forever" to keep moist. Printer ribbon work after a long time on the ink ribbon, then will gradually depleted, finally making the printer can not print properly the content. For example, we can use the two small bubble "soak" ink, the ribbon tightly in the middle.
2, the operation of skilled paper thickness regulator, for this purpose to ensure that the print head and the surface of the printer paper is always in the right distance. Because under normal circumstances, if the printer using the new ribbon when we can adjust the paper thickness regulator to avoid too strong to print out the handwriting effect. Can effectively guarantee the quality of the final print. We adjust the paper thickness regulator, the need for us to ensure print quality to meet the needs of full compliance with the premise can be big on the big principles.
3, usually the time to learn to use the printer ribbons "surgery." If you use the process encountered poor print ribbon cassette rotation phenomenon, then it will cause the printer ribbon re-use an area. We can put the ribbon among the "loopholes" in the section has been cut off and then use tape to stick together to cut the ribbon.
4, to add the printer ribbon "energy." That is an ink printer Ribbon. Ribbon work long hours will make the ink on the surface of the printer or less is consumed, if not promptly replaced printout results will not be satisfactory. We got two small bubble size appropriate and absorbing enough of the printing ink, the little foam tightly clamped exposed ribbon area outside of the ink ribbon cassette and gently twist the ribbon shaft can be.
