USER INTERFACE
OCR format must be 14-digits’ long in two rows, 7 digits over 7 digits, with the patient ID being 11
digits and a 3-digit CRC (which cannot be altered by the operator) at the end. The font must be 12
point OCR-A. Numbers only, no alpha characters.
Note: For OCR format, ‘9999’ as the last 4 digits before the CRC are reserved for field service use.
Slide IDs with those reserved numbers are removed from the patient database during a ser
-
vice visit, so do not use that sequence.
Slide barcode labels may be 1- or 2-dimensional. 1-D barcodes must meet ANSI X3.182 specifications
with a quality of grade B or better. See the table below for any restrictions. Slide labels may be
printed and applied or directly printed or etched onto the slide. (See
Figure 3-23.) In any case, make
sure the contrast is sufficient for the scanner to read the label.
