How to Replace Okidata Drums

Posted Thursday, July 1st, 2010 by .

Many printers use a separate drum and toner cartridge so that each can be easily replaced independently.  Other printers use a toner cartridge that includes the drum, so that both are replaced at once.  Okidata printers are unique in that they use a separate toner cartridge and drum, but they snap together into a single unit.  Though there are slight differences in cartridges and drums between various OKI laser printer models, the concept is the same.

Sometimes new Okidata customers who have recently purchased their first Okidata laser printer do not realize that the imaging drum and cartridge are two separate pieces locked together.  Thus, when they order a replacement cartridge, the size of it can be awfully confusing as it is considerably smaller than the full assembly.

What is MICR Toner?

Posted Thursday, July 1st, 2010 by .

MICR stands for Magnetic Ink Character Recognition and is a technology used mainly by banks.  The process was developed as a way for machines to read sequences of numbers that are also readable by humans.  The system is used on almost every check and deposit slip, as a sequence of numbers running along the bottom left.  The first number is most often the bank’s routing number, while the second number is the customer’s account number.

This is a frequently asked question because many people who are looking for standard toner will come across an option to get standard or MICR toner and want to clarify the difference.  MICR toner cannot be used in a regular printer that produces text documents or images- it is specifically designed for printing checks.  Once again, MICR toner WILL NOT work in standard printers.

MICR uses a specific type of toner that usually includes iron oxide, which can be magnetized by the machine reading the numbers, in a process very similar to a magnetic tape recorder.  Each character is easily identified by the system, even when there is an obstruction, such as a stamp, pencil mark, etc.  Each character creates a very different waveform when being scanned, so they are easily recognized by the machine.MICR

The system uses two very specific fonts, known as E-13B and CMC-7.  These fonts contain only numbers and a few other symbols which represent different banking terms such as transit and account number.  There are no letters included in the MICR system. Continue reading “What is MICR Toner?” »
