The Printer
The PFM1 prints on plain thermal paper using a thermal array print head. Fetal heart
rate, uterine activity, and fetal movement are recorded together with date, time,
recorder speed and mode. The printer also prints a header block each time the
printer is turned on and the units chart scale.
To load the printer with paper, open the printer door by pressing firmly on the lid of
the printer. It will then release and can be lifted to a fully open position. Remove the
chart roll bar from inside the printer and place through the centre of the new chart roll.
(The chart roll must be removed from its protective plastic cover and the sticky tab
holding the roll together removed.) Insert the roll into the recorder so that the thermal
side of the paper is uppermost.
Pull the paper out of the front of the unit making sure it is positioned below the door
catches. Close the door and latch by pressing down firmly on it.
To operate the printer press the Recorder On/Off button (situated immediately to
the right of the printer door). 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 PFM1 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’.
