Coper machines are common in office places, and copying ID cards and files are indispensable.So how to use a copy machine? To choose a suitable place to install copy, pay attention to anti -high temperature, dustproof, shockproof, and direct sunlight.Keep dry in the copy.Let ’s take a look at the principles, usage methods and common problems with the copy machine.
What is the principle of a copy machine
There are two types of copies we often use now; one is an analog copy machine launched by Scholas in 1949. Most of the copies of the currently available and selling copies on the market are simulated copy machines.The other is the digital copy machine launched by Canon in Japan in 1991. Some of the copies sold on the market are now a digital copy machine. Digital copy machines are gradually replacing the simulation copy with their superior performance.
1. The working principle of the simulation copy machine
The working principle of analog copy machine is: The optical analog image of the original manuscript is directly projected into the light sensing drums that have been charged through the optical system through exposure and scanning.The entire copy process.
2. The working principle of the digital copy machine
The working principle of the digital copier is: First, the simulation image signal of the original manuscript is converted into a digital signal through the charge coupling device (that is, CCD), and then the digital processing image signal is input toThe charging light drum is scanned, and the static potential image is generated on the sensing drum, and then the entire copy process is completed through the steps of development, transfer, and fixed shadow.Digital copies are equivalent to fusion of scanners and laser printers.
How to use a copy machine
1. Preheat
Press the power switch and start warm -up. There should be indicators on the panel and waiting signals.When the warm -up time is reached, the machine can start copying. At this time, a copy of the signal or an audio signal will appear.
2. Check the machine display
After the machine is warm, you should see if the display on the operating panel is normal.It mainly includes the following items: you can copy signal display, carton position display, copy quantity display as "L", copy concentration adjustment display, paper size display, all display can be copied normally.
3. Set copy number
Press the number key to set the copy number.If you set the settings, press the "C" key and then reset it.
4. Select copy paper size
According to the original size, zoom or shrink the multiplier and press the carton to select health.If there is a size carton in the machine, you can display it on the panel; if there is no display, you need to change the carton.
Frequently issues of copying process
1. Completed paper
When the paper is used up, there will be a box of empty signals on the panel, and the copy paper will be installed.Can continue to copy.
2. Instead of ink powder
The ink powder is not enough to light up the signal light, indicating that the ink powder in the machine is fast, which will affect the photocopy quality. It should be supplemented in time. Some models appear to stop operating by this signal machine, and some models can continue to copy.Before adding ink powder, you should shake the ink powder bottle or tube several times so that the ink of the block is crushed into powder.
3. Too much waste powder
The waste ink powder cleaned from the light drum is collected in a waste powder bottle. After full, the signal will be displayed on the panel. Some machines and ink powder use the same signal.When the waste powder is filled, it should be poured off in time.Some models require waste powder to not be reused, especially the single -ingredients showing machine, otherwise it will affect the quality of the development.
