3.3.1 Requirements for microscope slides
• To reduce the amount of glass dust and the
risk of mechanical failures, use only clipped
corner slides (45° angle on each corner).
• Slides to be used in the printers must be stored
appropriately in closed containers and pro-
tected from dust and moisture.
• Positively charged slides are inherently sticky
so they require special handling to insure reli-
able mechanical handling by the instrument.
• When the print job is complete, the printed
surface of the slide may be handled immedi-
ately. Please be aware, however, that the spe-
cial ink is alcohol based and exposure to al-
cohol in combination with physical contact
(rubbing) could cause the print quality to de-
grade.
Fig. 5
3.3 Print specifications
Only standard microscope slides with imprintable
colored edges (23) can be imprinted in the Leica
IP S (see Fig. 5).
Printing directly onto the glass is not possible.
The following slide sizes can be imprinted in the
Leica IP S: 76 x 26 mm, max. 1.2 mm thickness.
3. Instrument components and specification
23
The texture of the slide print surface is extremely
important for optimal print quality and durability.
The print surface varies considerably between
manufacturers, color selection and coated (pos-
itively charged) versus uncoated surfaces.
They can even vary from slide to slide in the
same lot.
Coloured print surfaces, other than pure white,
contain pigments that help the ink spread evenly
and adhere strongly.
White print surfaces should always be tested for
print quality and ink adherence before purchase.
Some slides have been coated over the print sur-
face as well as the glass, which can create prob-
lems with the adherence of the ink.
These slides should also be tested for print qual-
ity and ink adherence before purchase.

13
Leica IP S
Caution!
Slides made by other manufacturers must be tested before use. The test must include the
following steps:
Mechanical compatibility with the instrument. Imprint quality.
Chemical and mechanical resistance of the imprints against the reagents the slides will
be exposed to during the subsequent processing steps.
Important!
Leica Microsystems assumes no responsibility whatsoever for any damages due to im-
prints of poor quality or imprints made with non-reagent-resistant ink.
Slides manufactured by the same companies, but with special coatings as e.g. Superfrost
®-Plus slides for immunohistochemical applications proved to be difficult with regard to
processability, print quality and ink resistance.
We recommend these slides only for alphanumeric imprints (no for bar code) and also
recommend to test these slides prior to using them to verify whether the imprints on such
slides are sufficiently resistant to reagents.
The following slides have been successfully tested with the Leica IP S:
Clipped corner slides
• Erie – Leica Ink Jet Slides*, Superfrost (plain and plus)
• Knittel GmbH – Starfrost bevelled edge 45°
• Matsunami – Clipped corner slides
• Menzel – Superfrost
• Okando – Premier coloured end, plain and charged, bevelled edge
* Highly recommended, especially for printing 1 and 2 dimensional bar codes.
Distributed by many major lab supply companies.
Tested and recommended print media for the Leica IP S ink jet printer
IMPORTANT!
The use of other print media may result in unsatisfactory print quality and/or jamming of
slides/cassettes during the printing process!
If the slides/cassettes you are currently using are not listed above, please contact your
local Leica Microsystems’ representative.

3.3.2 Print specifications
Width Height
Format Dots mm Dots mm
Slide 360 25.4 256 18.0
Print resolution
The print head of the instrument has a fixed reso-
lution of 360 dpi in both directions (vertical and
horizontal).
Each printed line has a maximum height of 128
dots, corresponding to 9.03 mm.
Therefore, a maximum of 2 lines can be printed
on the slides.
In horizontal direction, the printable surface is
limited only by the size of the object to be imprint-
ed (Fig. 6).
The above values must be taken into consider-
ation when defining the print area (“paper size“)
in the application you are going to print from.
Print resolution
The printing area parameters listed in the table
below are defined in the printer driver.
24
Fig. 6
Print quality Quality and resolution of the imprints depend on:
• the material of the imprintable surface / the dyes used to color the
imprintable surface.
• the structure of the imprintable surface (24).
The final resolution of the imprints is not only determined by the resolution of
the print head.
If the slide surface is not capable of 360 dpi resolution, “running“ ink will
lead to poor printing results. In such cases it is better to work at a lower
resolution.
The printer driver therefore allows you to change the resolution from 360 dpi
to 180 dpi (see chapter 5.4 for further details).

3.3.3 Printing bar code
Printing readable bar code depends on various factors that need to be taken
into consideration in order to achieve results suitable for reliable and du-
rable archiving.
The main factors influencing the bar code results are:
• printer technology
• how the bar code is created
• the type of object being printed on
• the type of scanner used to read the bar code
Printer technology
• As a dot matrix printer, the IP C can handle information only in the form
of dots printed or not printed. It is not possible to transmit bar code data
or to select specific bar code types or use the printer to create and print
the bar code required.
Creating bar codes
• Since there is only limited printing space on the slides, the bar code
should not contain more information than necessary.
• You should use an error-checking code, which makes it easier for the
bar codes scanners to recognize possible errors. Some codes even sup-
port error correction.
• When calculating and creating bar code, always bear in mind the resolu-
tion of the printer.
The module size is the width of the smallest element of a bar code. Wider
bars and spaces are calculated in multiples of the module size.
The module size always has to be an entire divisor of the printer resolu-
tion, as, due to the technology applied, only ‘whole’ dots can be printed.
Reading errors may occur (even if the print appears to be crisp and cor-
rect), if, due to conversion, module width and resolution do not match
any longer.
Data should never be printed as bar code only, but also as text
(line of optical characters above or below the bar code), to en-
sure that no information is lost for the above reasons.

16 Instruction manual V 1.6 – 07/2005
3. Instrument components and specification
Bar code scanners
The scanning results obtained not only depend on the correct bar code cre-
ation and on the quality of the cassettes but also on the features of the
barcode scanner used.
Features to bear in mind are:
• Reading tolerance:
difference between actual bar width and nominal module size.
• Light color:
the light color of the barcode scanner should be opposite (highly
contrasting) to the color of the cassettes being used.
• Optical resolution:
must be better than the module size.
Depending on the application, the following features should also be consid-
ered:
• Maximum readable distance
• Maximum inclination angle
Leica has tested successfully the following readers:
Datalogic - Model ‘Gryphon’ (for 1D-Barcode)
Datalogic - Model ‘Lynx D 200’ (for 1D and 2D-Barcode)
Requirements for Barcode Printing
The quality and readability of printed barcodes will depend on several fac-
tors that include:
• Texture and quality of the print surface on the selected cassette or slide
• Color of the selected cassette or slide
• Bar code style
• Number and types of characters required in the barcode
• The quality and resolution capabilities of the bar code reader
As always, using Leica recommended print media would produce the high-
est quality print. However, it is highly recommended that any barcode solu-
tion be tested prior to implementation.
Please check with your local representative for details on achieving the
maximum number of characters with 1D or 2D bar codes.

3. Instrument components and specification
3.3.4 Resistance against reagents
Important!
All laboratories must perform their own tests to ensure that the ink is resistant against the
various reagents the slides will subsequently be exposed to.
A wide range of factors beyond Leica’s control can have negative effects on the results.
The test conditions stated below can therefore only serve as an outline for individual
laboratory test specifications.
The laboratory operating the unit shall bear full responsibility for the legibility of the im-
print after processing with reagents.
Test conditions
Imprinted slides were tested with a variety of reagents in an environment
simulating the conditions present during tissue processing.
The following slide types were tested:
• Erie – Leica Ink Jet Slides*, Superfrost (plain and plus)
• Knittel GmbH – Starfrost bevelled edge 45°
• Matsunami – Clipped corner slides
• Menzel – Superfrost
• Okando – Premier coloured end, plain and charged, bevelled edge
A variety of colors of all of the above slide types (although not all colors
available of each slide type) were tested.
An influence of the slide color on the resistance of the imprint could not be
verified.
It cannot be guaranteed that the ink will be absolutely smudge-proof under all foresee-
able laboratory conditions, as stability of the ink against wiping largely depends on the
surface structure of the imprint field of the slide being imprinted.
Important!
The imprint field of imprinted slides should never be touched or wiped while damp.
