Logging Off the System
NOTE: After loading a basket and initiating a processing
cycle, it is recommended to log off the instrument if
individual passwords have been assigned to users. This
ensures that the next user must log on before initiating a
processing cycle, and helps maintain an accurate history
of processing by each user.
To log off of the instrument:
Touch the LOG OFF button in the lower right-hand
corner of the screen. The screen refreshes, and the user
name is removed from the top of the screen to confirm a
successful log off.
System Operation
System operation is comprised of four phases:
Figure 4-G
• Loading Tissue Specimens – A prepared bas-
ket or magazine set of specimens is placed in the
Loading Station retort, and the information nec-
essary to initiate the processing cycle is entered
using the Control Panel.
• Preprocessing –Tissue samples processed on
the Tissue-Tek
®
Xpress
®
x120 require proper
preparation and handling to ensure optimal re-
sults. An optional online step is available to pre-
treat tissue specimens prior to tissue processing.
Pre-Processing Solution (PPS) Product Code
7115 is used in the loading station. Users have
the ability to set the onboard preprocessing time
between 0-60 minutes. Once a preprocessing
cycle has been initiated, the preprocessing oper-
ation is performed automatically, under the con-
trol of the scheduling software and based on the
selected preprocessing time. The Control Panel
displays a “process monitor” screen that allows
tracking the status of a basket or magazine set
through the preprocessing cycle.
NOTE: Do not transport or leave specimens in PPS
overnight as this is a timed solution and over exposure will
compromise the tissue samples.
• Process Monitoring – Once a processing cycle
has been initiated, all processing operations are
performed automatically, under control of the
scheduling software, and based on the currently
selected processing program. The Control Panel
displays a “process monitor” screen that allows
tracking the status of a basket or magazine set
through the processing cycle.
• Unloading Processed Specimens – Once au-
tomated processing is completed, the processed
basket is placed in the Unloading Station for un-
loading and for transfer to an embedding station.
NOTE: The user must be logged on to the instrument to
load tissue specimens and initiate a processing cycle (see
“Logging On” on page 4.4 for details). It is not necessary
to log on in order to unload processed specimens.
Two programs can be selected in the program selec-
tion pull down list. The STANDARD program immerses
the specimens for 15 minutes in each retort. The
EXTENDED program immerses the specimens for 30
minutes in each retort. Touch the drop down arrow to
view the two programs and then touch the desired
selection (Figure 4-G).
NOTE: The program selection can only be made when
the instrument is ready, but not processing specimens.
