9.6 Loading printer paper
When the printer tray is opened, a help screen displaying the following diagram is shown. The screen may be
closed by closing the paper tray or bypassed using the back button
.
Note: Ensure the paper remains centrally aligned while closing the drawer.
IMPORTANT: As paper tracks through a printer mechanism it will move from side to side due to variations in
paper and printer mechanism alignment. This is an unavoidable feature of all printers of this type, as used
in all makes of fetal monitors. With plain paper, where the grid is printed at the same time as the trace data,
any alignment error is eliminated, ensuring 100% print accuracy. With pre-printed paper, this error cannot be
eliminated and will result in alignment errors between the trace and the grid.
