Printer troub leshooting
Printer With the decline in prices, has begun to spread. In the process of using the printer, the most common problem is the printer can not print, this problem bring some trouble to the user.
First make sure the printer is online, on most printers, "OnLine" button next to have a little light indicates online status, normally the online indicator should be in steady state. If the light is off or is flashing, indicating that online is not normal. Check the printer is turned on, the printer's power switch is turned on, the printer cable is properly connected and the like. If the online indicator shows online correctly, please turn off the printer, and then turn again to try to print the document. This action can clear the printer to print a document stored in memory, data and can solve many problems, but sometimes this method will result in printouts with confusion, you need to reboot the system after normal printing.

Needle type printer ribbon fault

1, the ribbon fracture
Tensile strength of the ribbon is too big, snap sutures or hammer smashing the ribbon ribbon fracture cause. Former broken part can be cut and sewn back; The latter case as long as change the ribbon.
2, the ribbon was stuck
The edge of the ribbon easily entangled epson printer ribbon  ound after take off a silk, burr, led to the card and ribbon round the ribbon not retract properly foil box. The solution is: first, open the printer cover, transfer ribbon arm interlock with hammer handle to open, the ribbon on the ribbon box to send belt end back gently, and then close the ribbon jib to interlock with hammer handle, open the power supply, machine ribbon will comes back after self-checking foil box.
3, damage of hall effect
Ribbon cassette, frequently hall effector squeezed continuously, causing the damage fracture. This kind of failure can only replace the ribbon derrick assembly or use the compatible olivetti printer ribbon motion sensor replacement.
4, the active wheel drive of ribbon belt wear or fracture
This failure is due to the driving belt use time is too long or character chain caused by friction drive belt. The solution is to adjust the position of the character chain to make it no longer friction driving belt; Has been broken, please replace.
5, ribbon movement sensing signal is interrupted
First check to see if the ribbon movement sensing signal lines has been damaged, if broken, please replace signal lines; To check the interlock switch board J6 socket in the ribbon movement sensing signal whether damaged or contact is not good, please replace or good signal lines.

Needle printer

Needle type printer is a special kind of printer, and ink-jet, laser printers are there is a big difference, and this difference needle type printer are other types of printers can not be replaced, it is precisely because of this, needle type printer always have their own unique market share, in the service of some special industry users.

Needle type printer in the print head is through 24 needle hit the carbon paper, thusforming a font, in use, the user can according to the demand to select multiple paper,commonly used multiple paper 2 joint, 3 joint, 4 joint papers, which have also used the6 associated printer paper. Multiple paper disposable needle type thermal transfer printer ribbon printer can onlyprint finished quickly, ink jet printer, laser printer is unable to realize the multipleprinting paper.Basic ----1964 years, Olympiad held in tokyo. At that time, responsible for providingtiming products Epson Corp especially developed crystal chronometer 951 and printtype chronograph. These two products are not only at the time to shine, but also for the future company transformation and Printer ribbon diversification brought profound R & D base and opportunity. Development - the world's first PC with mainstream needle type printerIn 1978, Epson Corp issued a needle type printer (7 pin) TP-80, product well received. In 1980, MP-80 (pin 9) published, also caused a sensation in the world,second years, MP-80 in the Japanese market share as high as 60%, in USA marketalso received high evaluation, gradually become the mainstream of the world's firstneedle type printer for PC products.

Introduction and basic structure of thermal transfer ribbon

Thermal transfer ribbon called hot foil stamping ribbon, referred to as the ribbon,English is Thermal Transfer Ribbon.

Thermal printing ribbon is printer supplies, is on the side of a base coated with wax,resin or mixed ink polyester or other high density film. In the absence of ink coated on one side with a lubricant to prevent wear and damage to the print head, a commonshaft core TTR printer ribbon with paper and plastic two, the main requirement is not deformationand not in print slide. Common ribbon with wax, wax tree based mixed base, resin based several. China, use of the IBM printer ribbon are common date code Tandai, infusion bagribbon, washing cloth, special resin ribbon cable with ribbon, barcode ribbon, wax -ribbon, mixed base - ribbon, ribbon and other kinds of resin matrix - type. Different materials and varieties of ribbon / ribbon for printing materials and printers have different applicable in thermal transfer ribbon, ribbon / technology, printerperformance is the primary.

A) thin but strong polyester or other high density material with base;

B) bottom coating with matrix positive to ensure that the ink evenly and printing inktransfer complete;

C) ink layer of wax or resin base;

D) outer coating layer on the printing ink in ink and enhanced protection andadhesion of printed material;

E) back coating base with anti-static, both heat and reduce friction, in order to protect the print head.

The application field of the thermal transfer ribbon and the principle of work

Thermal transfer ribbon is a very wide range of uses, the amount is very hugeproducts. With the development of information technology in China and rapid development of computer application domain unceasing expansion and in-depth,people of high speed, high quality output print demand more and more, and the traditional way of printing market in terms of price, printing quality, printing speed is difficult to meet the user needs in all directions. Thermal Nylon ribbon roll  made of high strength thin films due to the high concentration and ink, and the use of single usemode, so the printing characters of high quality, long service life and overcome the ribbon, inkjet feathering, easily soluble in water and other defects, thermal transfer printing method to print medium without any requirements, can be in plain paper,recycled paper, wax paper, ordinary film, envelopes, paper label until the cloth to achieve high clear print.

Thermal transfer imaging method was invented by Mille in 1953, along with thedevelopment of microelectronic technology, lithography technology, the semiconductor electric heating element technology and laser technology, especially the development of high sensitivity thermal transfer imaging functional materialtechnology, thermal transfer printer as a non-contact printing computer peripheralshard output devices, has become a market share special kind of printer of high rate.The imaging principle of thermodynamics is heat transfer to the imaging materialsupport body through computer signals to drive the semiconductor electrothermalhead or laser imaging materials, make hot melt and transferred to the text and imageby image forming medium. Thermal transfer imaging material is coated on the base tape, called thermalepson printer ribbon  or thermal transfer ribbon.
