Chapter 3: Slide Preparation
`
Make sure there is only one coverslip attached to the slide.
`
Wipe the coverslip clean of dust and fingerprints before loading the slide in the scanner.
Labels
The
Aperio GT 450 DX supports common industry labels used for 1 x 3 inch (2.54 cm x 7.62 cm) slides. Improperly applied
slide labels can cause slides to jam.
Ensure the following:
`
Do not apply multiple labels to the same slide—this can cause the slide to exceed the specification for slide
thickness. See the
Aperio GT 450 DX Scanner Specifications
for slide specifications.
`
Labels do not extend past the edges of the slide and do not cover any tissue.
`
Labels are not underneath coverslips.
`
Labels are firmly attached.
`
Do not apply labels to the bottom surface of the slide.
`
Always load slides into the rack with the label facing out and up, as shown in
“Load Slides in the Rack” on page 32
.
The examples below show a slide with multiple labels that cause the slide to exceed the allowable maximum thickness, and a
slide with the label peeling away:
Barcodes
For a list of supported barcodes, see
“Barcodes Supported” on page 26
. For best performance, we recommend using
barcode labels that have a white background and black ink.
Improperly applied slide barcodes can cause slides to jam. Ensure the following:
`
Barcode labels meet the same application requirements as slide labels. See
.
`
Apply barcode labels to the slide label region.
`
Ensure a minimum of 0.5 mm between each side of the barcode and the edge of the label.
`
Apply only one barcode label per slide.
`
Use only supported barcode labels. (See
“Barcodes Supported” on page 26
`
Use only high-quality printed barcode labels.
