Head Temperature Detection
To obtain the best possible printing results the printer head should be thermally controlled
according to the temperature that is sensed. In addition, in order to prevent a fire, etc., caused by
an abnormal rise in temperature at the head, the head temperature is always monitored so that it
does not exceed a specified temperature. If the head temperature exceeds the specified
temperature, the energy supply to the head is forcibly stopped.
Hardware Error Detection
If it is detected that the printer fails and continues to output the strobe signal (i.e. applying energy
to the paper), the printing operation stops.
Splash Cover Detection
Before printing, or before feeding paper, the splash cover status is detected automatically.
Printing, or feeding paper, cannot be performed while the splash cover is closed.
Head temperature hold function
The function controls head temperature at the right temperature at all times, or for a set period.
The head temperature hold function controls temperature as follows:
• If the head temperature has not reached the right temperature, it is raised until it reaches that
temperature, after which further temperature increase is stopped.
• When the head temperature hold function is enabled, head temperature is still maintained after
PRNClose is executed.
※ APO operates according to settings after PRNClose.
• The head temperature hold time can be set to constant, or in units of five minutes up to one
hour.
※ The specified time is the time elapsed after the last time the head temperature hold
command was sent. Printing time is included in the elapsed time, but suspended time is not.
• The head temperature will not rise while the I/OBOX AC adapter is connected (during
charging).
※ The battery does not charge while the head is being heated, so the head heating is stopped
while the I/OBOX AC adapter is connected.
When the head temperature hold function is enabled, thermal energy is applied to the printer even
when it is not printing, which negatively impacts print volume.
The back barcode reading function
This function can read a barcode on the back of the paper during printing, and acquire the decoded
result. There are two specifications of barcode that can be read, as stated below.
