Tips and Tricks – DPM, Hard-to-Reach Marks
• If the mark is small, move the reader closer while holding the trigger.
• If the code is difficult to read, change the reader position while holding the trigger.
• If needed, check the readability table to confirm that the code density can be read at the current
working distance.
• If reading a part at greater than 4" (±100 mm), position the reader at 15° for improved decoding.
• Check that the reader can "see" the entire code, i.e., code size < FOV (field of view).
• Check that the correct code type is currently enabled.
Important: Aztec Code and DotCode aren't enabled by default.
• If needed, enable Advanced Features: 2D Damaged Mode, Attempt Morphology Manipulation,
etc. (disabled by default).
• Check that the symbology features are enabled properly.
Important: DMRE (Data Matrix Rectangular Extension) is not enabled by default.
• For Data Matrix codes, only ECC 200 is enabled by default. If necessary, legacy ECC 000 - ECC 130
can be enabled by the user.
• If the code is difficult to reach due to access constraints caused by the physical form of the part,
disable the Time of Flight sensor and perform a localized quick focus on the image.
• For parts in color, select the proper lighting color to create contrast when using Dome Lighting
(RGB available).
• Using the opposite light spectrum will make the target appear darker.
• Using the same light spectrum will make the target appear lighter.
• The target can be the code's foreground or background color.
