Replacement of my printer

　　My printer suddenly came to a standstill and I consulted its users' manual, but in vain. Next, I sent an e-mail to the customer support division of the company. They advised me about the repairs, but also in vain. The last measure was to replace some parts, but it was a little costly. I bought it three years ago at the price of 24000 yen (about 200 US dollars), and the price of the repair parts was 8000 yen. So, I decided to get a new up-to-date model.
　　However, I found out that there was a problem. I had more than a dozen spare ink cartridges in my office. They would be on the brink of being discarded if the new model would have been installed. This occasion was called "mottainai" in Japanese. A Japanese word of "mottainai" is an adjective to describe such an occasion when you throw away what is still available.
　　Finally, I made up my mind to buy the same one as I bought three years ago. This type of printer was naturally outdated, and was on a clearance sale at a fairly cheaper price on the net. I got one for 8400 yen, though the parts of it cost 8000 yen, and anyway, now it works well.
　　By the way, I wondered if it is ok for such a multifunctional printer to be sold at such a low price. Did people who had something to do with the production of this printer make enough money?
　　One of my friends who works in the IT field told me about the "razor and blades" method. It seemed that they sold the razor almost for free and made money with the sales of its blades. I got it.
