cardboard at the bottom of the paper.
Inspect the paper tray to see if there is
any broken plastic.
Bring out ½ sheet of paper and close
the door completely. Go into the

Excess artifact
Verify they are using Welch
Allyn electrodes
Pull the clips off the end of all lead
wires, visually inspect the banana plug
for corrosion, push the clips back on the
lead wires. Inspect the metal part of the
clip that comes in contact with the
electrode for contamination or
corrosion. Clean or replace if needed.
Inspect the lead wires for cracks in the
wires.
Unplug the lead wires from the
AM12/AM15E/WAM and push them
back in again.
Attach a simulator and view waveforms
on the screen for artifact. If artifact is
present, test the unit using another
AM12/AM15E/WAM. If artifact is still
present, contact Welch Allyn Technical
Support.
If no artifact on the simulator, turn off
the simulator and gently bend all wires
