36 Instructions for Use V1.1, RevB – 10/2012
• Every time the system transfers a slide carrier from station 14 to the exit tank, an audible
signal (beep) is emitted to inform the user that slides are available for removal.
• The system also increments its count of the number of slide carriers that are in the exit
tank.
• The operator should remove processed slides as quickly as possible.
• The exit tank can hold up to four slide carriers. This enables the operator to remove the
slides at a more convenient time.
• As soon as there are 3 slide carriers in the exit tank, the stainer emits a distinctive audible
signal to alert the operator.
• In this case, the slides should be removed immediately, before the counter in the system is
set to 4;
5. Operation
5.5.5 Removing Processed Slides
Removing processed slides means more than the mere physical act of removing slides.
It also involves informing the instrument that slide carriers have been removed, so that the
stainer may keep an up-to-date count of how many slide carriers are still in the system.
Important!
As soon as there are four slide carriers in the exit tank, the stainer stops process-
ing, because the exit tank cannot hold any more slides.
• It is often convenient to insert new slides for staining at the same time as the processed
slides are being removed.
In this case it may be assumed that the operator normally removes all the stained slides
from the exit tank every time new slides are loaded.
