While the stylus is tracing the reference frame, confirm that the stylus if staying
perpendicular to the shape as it traces all four sides. If not, please address ASAP.

will always find their way into the lower section causing potential damage to the precision
components.
CAUTION: Never blow air into tracer.
Rim Retainer Pins
Inspect the condition of 8 pins. Replace any torn or missing covers prior to tracing
frames.
Stylus Tip
Remove any debris that may be attached to the tip of the stylus. Make sure there is a
smooth fluid vertical motion when the power is off.

please address ASAP.
Screen
If you're using a thin protective sheet for the screen, consider replacing this in order to
maintain a clean screen appearance and minimize the possibility of data errors.
Protective Sheet
Tracer
While the tracer is idle, confirm the home position of the stylus is parallel to the slot (see
ref. # 3 below).
Confirm that your stylus rotates 45 degrees to the right (see ref. #4 below) and 45
degrees to the left (see ref. #5 below) from the normal initialized position. If the 90
degree range exists but it's shifted unequally from the initialized position, please address
