Information

Thermal resume control technology

The thermosensitive printing head is printed by the instantaneous rise and decline of the resistance temperature of the heating body, and each heating body is made.

The process of rising and falling of the unit temperature is transmitted by its own initial temperature (regenerative) and the peripheral heat body resistance unit.

The effect of heat. In general, there is no need for complex control for a heater with constant temperature. But in practice

On the other hand, if the effects of heat storage and heat transfer are considered, the printing energy applied to the heating body is required, especially in the case of heat transfer.

In the case of high speed printing, the influence of heat storage is very great, so the adjustment of Inca energy is very important.

The process of adjusting the energy of the heating body is called the thermal resume control. Usually hot resume control is a pass

It is realized by adjusting the heating time (Ton) of the heat body.

In particular, in order to obtain higher printing speed, the cooling time of the heater should be shortened. If the fever body is single

The element can not release heat enough quickly enough, then the next pulse may be applied before the temperature is reduced to the base level.

The printing energy of the next point is too high, which can lead to poor printing quality and even shorten the life of the print head.

Thermal resume control means that the same heating unit can be adjusted more when the unit is stored with heat because it is printed on the front line.

Short pulse print width to print a point. It can be provided by the hot resume control driver IC on the print head, or

It is realized by using the print controller to use the multiple pulse width within the periodic time.

Therefore, the purpose of the thermal resume control is to improve the printing speed of TPH while guaranteeing the quality of the printed word.

PIG

In the implementation of heat history control

As mentioned above, if the heat body unit is known to maintain a partial print of the heat in the previous row, the thermal resume control is the same.

A set of techniques designed to reduce the width of the printing pulse, that is, the use of different pulse width point by point.

In general, the heating time of all the heating elements selected by the STROBE signal startup is the same. Printer control

By carrying different data to the print head several times in a single print row, the generator briefly starts the heating unit,

It can realize the control of the thermal record, thus producing the different total pulse width of each point. What is the burden on the controller to calculate

The heater unit needs to receive a number of supplementary pulses.
