Define the Term Micr
mind 1 Define the destination MICR and explain what it is. Using a suit qualified ex ample, discuss how does MICR take aimers compute and what is it apply for? resoluteness MICR, or Magnetic Ink Character Recognition, is a quotation recognition technology accustomd primarily by the banking industry to alleviate the processing of cheques and makes up the routing number and account number at the goat of a cheque. It allows computer to read account number off printed documents. Its diametric and unlike with barcodes or other similar technologies, MICR codes can be substantially read by humans. MICR characters usually contain iron oxide.They argon printed in special typefaces with a magnetic sign or toner and in the ashes of either and E-13B or CMC-7 Font. Each pillow slip series is made up of a series of numbers and symbols specifically designed for readability on obstructer sorting elevator cars which read and extremely high rates of speed. The machine can always deter mine what each series of number signifies quickly, referable to the symbols provide a beginning and end pint for each class of numbers. Line placement, character placement skew and tone are some(prenominal) critical components of printing MICR the line must be precisely positioned in the MICR Clear Band area.The drill of magnetic printing allows the characters to be read reliably even if they choose been overprinted or obscured by other marks, such(prenominal) as cancellation stamps and signature. The magnetic scanning of a typical check has a smaller error rate than with optical character recognition systems. As for well printed MICR documents, the cant read rate is usually s spark than 1% while the misread rate is in the order of 1 per 100,000 characters. A cheque is a suitable example to discuss how MICR readers work and what it is apply for does.When a bank receives a check for payment, is uses an MICR inscriber to print the aggregate of the check in MICR characters in the lower-right corner. The check then is sorted or routed to the customers bank, along with thousands of others. Each check is inserted in an MICR reader, which sends the check information including the amount of the check to a computer for processing. When you balance your checkbook, allege that the amount printed in the lower-right corner is the same as the amount scripted on the check otherwise, your statement will non balance. Some retailers use MICR reader to minimize their exposure to check fraud.Corporations and government agencies also use the technology to speed up the sorting of documents. The banking industry has established an supranational standard not only for bank numbers, but also for the font of the MICR characters. This standardization makes it possible for people to write checks in other countries. Question 2 Discuss what a optical maser printer is and how it differs from Thermal Printers. Answer A optical maser printer is a high-speed, high quality nonimp act printer. Its a printer that uses a focused beam or light to transfer text and images on to paper.Though contrary to popular belief, the laser does not actually burn the images on to the paper. The laser beam will plague at the surface of a cylindrical drum called a photoreceptor kind of of as a paper passing by the printer. This drum has an typically positive electrical charge, that is reversed in areas where the laser beam hits it. The laser beam is able to print patterns such as text and pictures on to the photoreceptor by reversing the charge in certain areas of the drum. Once the pattern has been created on the drum, it is coated with toner from a toner cartridge.The positively charged toner clings to areas of the drum that have been minusly charged by the laser. The drum is given a strong negative charge which allows the toner to transfer and stick to the paper when the paper is passing through the printer. Laser printers do not use ink therefore they have less smearing problems that ink-jet printers and are able to print pages faster. While laser printers typically cost more that inkjet printers, most laser toner cartridges last longstanding than ink cartridges, which makes their cost per page is about equal.Based on this reason, businesses lean to use laser printers, while consumers are more likely to use inkjet printers. A thermal printer generates images by pushing electrically heated pins against heat-sensitive paper. basic thermal printers are inexpensive, but the print quality is low and the images tend to fade over time. Self-service bumble pumps often print gas receipts using a built-in lower-quality thermal printer. Many point-of-sale terminals in retail and grocery stores also print purchases receipts on thermal paper.Two special types of thermal printers have high print quality and can print at much faster rates than ink-jet and laser printers. A thermal-wax-transfer printer generates rich, nonsmearing images by using heat to mel t colouringed was onto heat-sensitive paper. Thermal wax-transfer printers are more expensive than many color laser printers. Both printers have advantages and disadvantages by comparing we are able to differentiate them. The advantages of a laser printer are it is an accessible and high-octane office document printer. The document quality is very high, except for barcodes.There are a few disadvantages for a laser printer. It prints trails in sheets and resulting in waste. Its cross out and wristband adhesives can ooze from fuser and cause jamming. The barcodes require more ink and the toner is driving up the costs. Lastly, output susceptible to toner flaking and smudging. As for thermal printers it has more advantages than a laser printer, such as it is designed specifically for label and wristband printing, print on demand which does not lead to wastage, it is unanalyzable to operate and the best part are its durable, it has low maintenance and its does not have toner expense s.The disadvantages of a thermal printer are, for example they cannot print 8 1/2- by 11-inch documents and the printers are not readily available in hospitals today.
