To Jane teach you how to buy second-hand copiers

With the continuous introduction of new photocopiers, many old-fashioned photocopiers have been eliminated in large and medium-sized cities. These second-hand photocopiers are mainly sold to units or individuals in more remote areas. Because of the low price, there are many units and individuals who buy second-hand photocopiers. These copiers generally only have a one-month replacement period and a warranty period of three months to six months, and some even do not have a one-month warranty period, so make a brief introduction to several points that need to be mastered when buying second-hand copiers.

1. don't be fooled by appearances

Good looks don't work here at all! I believe that when you buy second-hand copiers, you must be thinking that the performance of the machine is better! However, to what extent it is better, the heart is not at all spectrum. When seeing that 70% of the second-hand copiers are new, many people will think that this copier must be eliminated by large units and well maintained! The author will say to you-big mistake! The initial misunderstanding of buying second-hand copiers is that they are easily confused by their appearance. Now there are special renovation technologies that can make second-hand copiers as brand-new as new machines. Moreover, if only one special paint is applied after polishing during renovation, the machines look 70% new. When the second paint is applied, the machines are absolutely brand-new! This is why you can see that 70% of the second-hand photocopiers are new. It is also very simple to see through-in some places where it is not easy to spray paint-few merchants can be careful to that extent.

2. estimate the usage time of the machine according to the counter

First of all, it is best to look at some information before buying second-hand copiers and master some commonly used copiers. When buying photocopiers, be sure to open the chassis and look at the counter. Don't be afraid that the counter will be adjusted. Generally, it is not a photocopier that is broken to a certain extent. The technicians of the merchants will not disassemble all the photocopiers. It is very troublesome to adjust the number of old-fashioned photocopiers. If it is 100000~200000 photocopiers, it indicates that the machine may be eliminated due to slow speed and severe power consumption; if it is 200000~350000 copies, then the copier will generally have more than three years of use time, because the unit usually copies only 40000~100000 copies a year, so this copier needs to check all important components in detail. Copiers with more than 350000 copies are generally very aging. Even if they look new, it is better not to buy them, because the components inside the machine will have problems due to pollution, wear and other reasons, even if it can produce better copy effect during the test machine, it will soon enter the state of overhaul and scrap. Of course, machines for different purposes will have different standards. For example, photocopiers for graphics and text will generally be above 200000, while production machines will generally be above 350000.

Review of 3. Copier Drum Components

It can be said that the most important thing in a copier is the drum assembly. The drum assembly is one of the most direct and important factors affecting the copying effect. First, take the drum out of the copier and carefully check whether there are obvious scars. If the scars appear many, messy and deep, it means that the drum assembly can no longer be used for a long time. Even if you use some methods to make the copy look good for a while, you can't buy it. The specific inspection method is: let the powder concentration of the machine be adjusted to the deepest, and then empty one sheet to check whether there are thin linear vertical lines. If so, the drum is damaged;

4. view the carrier in the cartridge

You can ask the merchant to open the carrier in the cartridge to see if it is full, and you can ask for a new carrier. It should be noted that the carrier is one of the keys to image imaging, and the quality of the carrier is related to the entire copy effect. Some copiers will have problems soon after they are purchased: obviously the toner is just bought, but the copy is not clear. if the carrier is about to be replaced, but you don't know, then you will have to spend hundreds of dollars to replace it.

5. check the paper slot and the display of various data lights

You can put some paper, and adjust the depth of the ink to a deeper, one-time walk on dozens of sheets, see the paper jam rate is not high, if the paper jam rate is high, you must adjust the inside of the copier, or replace some components. It should be noted that both 16K paper and 8K paper need to be tried. If conditions permit, you can also take this opportunity to observe the power consumption. Carefully check the display status of each data lamp on the panel. If some data lamps fail when pressing the button, you may as well ask the merchant to adjust or replace the new parts. In particular, because the ink deep button has the highest usage rate, it must be repeated, otherwise there will be a lot of trouble after buying it back.
