The principle of thermal printer:

A transparent film is applied to a light-colored material (usually paper) and the film becomes dark (mostly black, but also blue) after heating the film for a period of time. The image is created by heating and creating a chemical reaction in the membrane. This chemical reaction takes place at a certain temperature.

High temperatures accelerate this chemical reaction. When the temperature is below 60, it takes a considerable amount of time, even up to several years, for the film to become dark; At a temperature of 200 °C, this reaction is done in a matter of microseconds. <>

Thermal PrintersThermal printers selectively heat the thermal paper at a determined location, from which the corresponding pattern is produced. Heating is provided by a small electronic heater on the printhead that comes into contact with the heat-sensitive material. The heater is logically controlled by the printer in the form of square dots or bars, which, when driven, produces a graphic corresponding to the heating element on the thermal paper.

The same logic circuit that controls the heating element also controls the paper feed, so that the pattern can be printed on the entire label or paper.

Open the fusing part and the cover of the powder bin part and close it again. If it doesn't work, will the cover sensor be knocked off when the cartridge is installed, and check it.

The failure of the upper cover of the Toshiba 181 copier is one of the common faults, and many users have reported encountering this problem. The manifestation of this failure is that the upper cover of the photocopier cannot be closed normally or cannot be fixed on the main unit of the copier, and in serious cases, it will also cause the copier to be unable to use normally. So what is the cause of this failure?

How to fix it? Cause of failure:1The latch of the upper cover is damaged. The upper cover of the photocopier generally has two locks, which are fixed on the main unit and the upper cover, if the lock is damaged, the upper cover cannot be closed normally.

2.The upper cover impact switch is damaged. The upper cover of the photocopier is generally equipped with an impact switch to detect whether the upper cover is closed or not. If the shock switch is damaged, the upper cover will not be fixed to the main unit.

3.Aging of the top lid e-chain®. The photocopier has an e-chain® above the upper cover for the transfer of data and power cables. If the energy chain is aged, the data and power cables will be disconnected, which will affect the normal operation of the machine.

Solution:1Replace the upper lid lock. If the fault is caused by a damaged upper lid latch, then a new one needs to be replaced. This repair is relatively simple, just open the upper cover, remove the damaged latch, and install a new one.

2.Replace the upper cover impact switch. If the fault is caused by damage to the impact switch on the upper cover, a new impact switch needs to be replaced. This repair cover needs to be opened with a disadvantage, the original impact switch is removed, and the new impact switch is reinstalled.

3.Replace the top lid e-chain®. If the fault is caused by the aging of the e-chain® on the cover, it needs to be replaced with a new one. This repair requires opening the lid and removing the existing e-chain® and installing a new one.

Summary. The failure of the top cover of the Toshiba 181 copier is a relatively easy failure, and the main cause is the damage or aging of the top cover accessories. For this fault, it is necessary to select the corresponding maintenance plan according to the specific situation, replace the parts or repair it.

In the process of daily use of the copier, we also need to pay attention to the maintenance of the machine, find and eliminate faults in time, and ensure the normal operation of the machine.

Toshiba Copier 167 shows closed side cover for the following reasons:

1. Open the side cover of the photocopier and close it again.

2. If the copier's cover sensor is damaged, contact the after-sales service to replace the sensor.

3. The main control board of the photocopier is faulty, resulting in abnormal sensors, contact the after-sales service for replacement.

You can check it like this: 1. Check whether the side cover is closed, if it is closed, please carefully check whether there is deformation. 2. Check the front cover, because there is a protruding plastic strip object on the front cover, which is inserted into the linkage switch, which is the hole Reed linkage switch on the front cover sensor.

I think it's more likely, because it's easy to break.
