The paper cutter cannot be reset after the paper is jammed—the cutter is stuck—unplug the power supply and then plug it in again.

The paper cutter can't cut the paper—the gear is stuck—open the roll paper cover. If you find that the top right pinion and the lower gear are glued together, gently pull it up (note: unplug the power first)

Common fax machine types on the market

Thermal paper fax machine, thermal transfer fax machine, inkjet fax machine and laser fax machine.

How the fax machine works

Different types of fax machines print differently after receiving the signal, and the difference in their working principle is basically in these respects. There are two main types of fax machines on the market: thermal paper fax machines and inkjet/laser fax machines.

The thermal paper fax machine melts and discolors the heat sensitive material on the printing medium through a thermal printhead to generate the desired text and graphics. Thermal transfer has evolved from thermal technology by heating the transfer ribbon to transfer the ink applied to the ribbon onto the paper to form an image. Thermal printing is used in the most common fax machines.

The laser type plain paper fax machine is a kind of facsimile machine which uses carbon powder attached to paper to image. The working principle is mainly to utilize a toner cartridge for controlling the laser beam in the body, and to control the opening and closing of the laser beam, thereby generating the toner cartridge. The charged image area, at which point the toner inside the fax machine is attracted by the charge and adheres to the paper to form a text or image pattern. The working principle of the inkjet fax machine is similar to that of the dot matrix printing. The stepping motor drives the inkjet head to move left and right, and the ink ejected from the inkjet head is sequentially sprayed on the plain paper to complete the printing work. .

In addition, there is also a flatbed inkjet MFP on the market. Although their hardware does not provide fax function, they can use related software to realize the computer to send and receive faxes.

How to use the fax machine

Send a fax: Put the document to be faxed into the paper machine of the fax machine, dial the fax number of the other party, wait for the other party to connect, let the other party receive the signal, and finally press “confirm”.

Receiving a fax: When you hear the fax, pick up the handset, then press the "confirm" button to receive it, and the other party's fax will be sent.

Fax machine use precautions

1. Do not use non-standard fax paper. Inferior fax paper is not clean enough to cause wear on the thermal recording head and the paper feed roller. Unreasonable formulas for chemical dyes on recording paper can result in poor print quality and short shelf life.

2. Do not replace the power cord at will. The plugs of the power cords of the original fax machine are all 3-pin plugs, and the middle one pin acts as a protective ground. If you unplug it or use a two-pin plug, it is not safe.

3, the action of the paper box cover should not be too strong. Most of the thermal recording heads of the fax machine are installed under the paper compartment cover. When the paper compartment cover is closed, the motion of the paper compartment cover is too strong, and the paper compartment cover is deformed, which may cause cracking and damage of the thermal recording head.

4. Graphic materials such as staples and pins, as well as manuscripts with ink or glue that are not dry should not be sent. This is because the above hard object easily scratches the scanning glass or other device, causing the fax machine to malfunction. If the ink or glue on the manuscript is not dry, it will easily stain the scanning glass, causing the fax machine to transmit poorly.

5, do not boot frequently. This is because each time the switch is turned on, the electronic components in the machine will change between hot and cold, and frequent changes in heat and cold will easily lead to premature aging of the components inside the machine. The inrush current of each turn-on will shorten the service life of the fax machine. Frequent power-on is actually the best maintenance method for fax machines.

6, do not have high-powered electrical equipment around the fax machine, should not be used in high temperature, strong magnetic, strong corrosive gas environment. High temperature and strong corrosive gases not only affect the printing quality of the recording paper of the fax machine, but also adversely affect or destroy the electronic circuit. Strong magnetic fields not only interfere with the call, but also distorted images.

7. Do not use the fax machine as a copier. Important information should be saved after copying with an electrostatic copying machine. Someone used the copy function of the fax machine to copy the data. The main part of the fax machine to complete the copy function is the thermal recording head, which is one of the most important parts of the fax machine. It works on its own heat, so as to minimize the working time of the fax machine to extend the life of the fax machine. In addition, documents recorded on fax paper should not be stored for a long time. This is because the chemical dye on the fax paper is unstable, and the words on the fax paper will gradually fade after a long time or exposure to sunlight. Therefore, for important documents that need to be stored for a long time, be sure to use a photocopier to make a long-term copy.

8. The fax machine is jealous of dust. Once the dust enters the optical scanning system of the fax machine, it will affect the quality of the fax machine sending and copying. The dust enters the room from the gap of the window, and the possibility of problems with the fax machine placed under the window is greatly increased. Added, cleaning the fax machine scanning system, although it is not very difficult for professional maintenance personnel, but should also try to avoid trouble; In addition, if the window is not closed during the rainy season, the rain will enter the fax machine and cause short circuit failure will be very Tricky things.

Fax machine common troubleshooting solutions

First, the file copy is all black

Cause: The scanner, motherboard, or thermal head is faulty.

Processing method: First enter the service mode, test the thermal head, if there is a problem, replace it. If there is no problem, check whether the scanner socket on the main board is properly plugged in. If the plug is good, replace the main board first. If it still cannot be solved, the scanner is faulty and the scanner is replaced.

Second, the document is not clearly copied

Cause: The scanner or white roller is dirty.

Treatment: Clean the scanner and white roller.

Third, the document copy 1/4 white

Cause: The thermal head or scanner is malfunctioning.

Processing method: First enter the service mode, test the thermal head, if there is a problem, replace it. If the thermal head is good, the scanner is faulty and the scanner is replaced.

Fourth, the document is copied in all white

Cause: The motherboard, thermal head or scanner is faulty.

Processing method: First enter the service mode, test the thermal head, if there is a problem, replace it. If the thermal head is ok, replace the motherboard, the copy still shows all white, and then replace the scanner.

5. When the document is copied, one side of the writing is irregular.

Reason 1: The upper cover is not fastened or the hook on the side of the white is not in place.

Treatment method: Open the panel and press on both sides to re-fasten.

Reason 2: It may also be caused by a misalignment of the thermal head (TPH).

Solution: After opening the panel, press the thermal head repeatedly and adjust it to reset.

Sixth, the document is copied with a black belt

Cause: The scanner (CIS) has a dirty surface or a thermal head failure.

Treatment: You can clean the scanner first. If there is still a black belt, replace the thermal head.
