The Printer
The FETATRACK 310 prints on preprinted z-fold thermal paper using a thermal array
print head. Fetal heart rate, uterine activity, and fetal movement are recorded
together with date, time, recorder speed, operating mode and alarm status. The printer
also prints a header block each time the printer is turned on, that contains Time and
Date, Patient Name, Gestational Age, Patient or Bed Number, Hospital or Doctor along
with a print viability test bar that prints to all dots of the printhead.
To load the printer with paper, open the printer door by pulling the recorder door using
the opening provided on the printer. It will then release and opens downwards exposing
the printer paper tray. Remove the new paper pack from its protective plastic cover and
insert the pack into the recorder so that the printed side of the paper is uppermost and
the FHR trace is on the left.
Pull the paper out of the front of the unit making sure it is positioned parallel to the roller
and the close the door. The pack will self align when the recorder is run.
To operate the printer press the Recorder On/Off button. The printer will start to run
and the chart speed will be shown in the LCD display. To turn the printer off press
and hold the Recorder On/Off button until the printer stops. (This only operates after the
data block has been printed). A small amount of paper will be fed out at high speed.
The printer will record at 1, 2 or 3 cm/min. To change the speed during recording
simply press the Recorder On/Off button momentarily. The FETATRACK 310 can be
run at the speed of your choice, and will always start at this pre-programmed speed
every time the printer is turned on. For details of how to change the pre-
programmed speed refer to ‘User Configuration’.
When the paper pack runs out the Fetatrack 310 will sound a short alarm and display
“Paper ?”. For the next 30 min the system will store HR1 , HR2 and Toco until either the
store becomes full, the user presses and holds the Recorder On/Off button to reset the
store and loose the stored data or the user inserts a new paper pack, presses Recorder
On/Off button once and the Fetatrack 310 prints the stored data and returns to normal
printing.
When the store reaches 90% full the Fetatrack 310 will “Alarm” and show “StoreLow”, if
the store then becomes full the display changes to “StoreFull” and there will be no
further storage. The data can still be printed by pressing Recorder On/Off button once
or reset by pressing and holding the Recorder On/Off button.
The print from store is lighter than the normal trace to distinguish stored data.
