Printing with temperature compensation

Requirements

• Suitable printers: All devices listed in the headline of this document

• Firmware: All versions

Function description

The print contrast is heavily dependent on the temperature of the printhead.

This can be set using the parameter SYSTEM PARAMETERS > Print contrast or in

the online mode after pressing the Esc button.

When the printer is being used for a big print job, the temperature of the print-

head and the print contrast increase during printing. This increase is greater,

the larger the printjob and the larger the amount of black to be printed.

In extreme cases, this rise in temperature can lead to smearing in fine struc-

tures when printed, e.g. barcodes arranged crosswise to the printing direction.

To avoid this, the firmware constantly checks and corrects the printhead tem-

perature. The precondition for this is that the parameter SYSTEM PARAMETERS

> Temp. reduction is set to a value > 0 (Default: 20%).

¯ The temperature compensation is the greater, the higher the setting of the

parameter SYSTEM PARAMETERS > Temp. reduction is [1].

Parameter Function

SYSTEM PARAMETERS >

Print contrast

Sets the print contrast, i.e. indirectly, the printhead

temperature (actually adjusts the driving power of

the printhead).

SYSTEM PARAMETERS >

Temp. reduction

Sets the correction factor for the temperature com-

pensation. The higher the selected setting, the

greater the reduction of the driving power when the

printhead temperature rises.
