HandPunch Maintenance
A minimum amount of system maintenance is required to keep HandPunchs
fully functional. HandPunchs should be cleaned periodically to prevent an
accumulation of dust from affecting the HandPunch’s readability. User Scores
should be reviewed periodically to ensure the HandPunch is performing
properly.
There are NO user serviceable parts inside the HandPunch.
Once a HandPunch system is in operation there are two HandPunch commands
that can assist with system maintenance. These commands are performed
through the Service Menu. The instructions for these commands begin on page
32.
• Calibrate – View HandPunch exposure values.
• Status Display – Display HandPunch input/output status, the hand read
score of the last user to verify on the system.
Cleaning the
HandPunch Inspect and clean the HandPunch regularly to maintain optimum performance.
Clean the platen, side mirror, reflector, and the window above the platen using a
clean cloth dampened with ordinary, non-abrasive window cleaner (see Figure 9-
1). Start at the rear corners of the platen and work your way forward.
DO NOT SPRAY CLEANING FLUID DIRECTLY INTO OR ON THE HandPunch.

User Score Periodically check users’ scores (refer to the Read Score section on page 41).
Scores should average under 30. Occasionally a user will score above 30. This is
not necessarily an indication of poor performance. If a number of scores average
over 30, clean the HandPunch and check scores again. If scores remain high, or
if users are experiencing frequent rejections, run the Calibration command (see
page 32).
