Chapter 7:  Quality Control and Maintenance

Cleaning the AutoLoader Racks

Inspect racks for damage and for accumulated glass dust or

 

accumulated mounting media. All grooves within the rack (sides 

and bottom) must be

 

clean and smooth. Clean the racks as required with compressed air and/or cleaning

 

solvent. Damaged 

racks should be replaced immediately.

Clean racks frequently.

Recalibrate the AutoLoader Slide-in-Rack Sensor

Recalibrating the AutoLoader slide-in-rack sensor prevents scanning problems by ensuring that the slide moving from the 
AutoLoader to the scanning stage is precisely positioned. This procedure should be done every six months. (This will be 
done as part of your annual maintenance visit by Leica Biosystems Technical Services.) 

First you will restart the scanner Controller service. This initializes the scanner and puts the stage and AutoLoader in the 
home position. 

1. 

Turn the scanner off and back on: Press the main power switch on the back of the scanner to the Off position then 
press it to the On position.

2. 

Click the Service Manager icon 

 in the Windows task bar, select 

Restart Services

, and then select 

Restart 

Controller Service

. 

Now you will recalibrate the AutoLoader slide-in-rack sensor:

1. 

Open the AT2 DX covers to gain access to the inside of the scanner.

2. 

Locate the slide-in-rack sensor amplifier which is 
to the right of the AutoLoader cover.
