Hematek 3000 System – Instruction Manual – Version 1.3
You will need:
• 4 spare glass slides
To check the adjustment of the sensing switch fingers, proceed as follows:
1. Start the system, see Chapter 5.1 to Chapter 5.2.
NOTICE
If glass slides are not placed correctly in the grooves of the conveyor
spirals, this can cause them to break
Damage to the system can result.
• Glass slides must be inserted into the grooves of the conveyor spirals
so they are parallel to the slide loading lines inscribed on the platen, see
Slide loading lines on page 4-8.
2. Load 4 spare glass slides into the grooves of the conveyor spirals. 
The system performs the staining.
3. Check if the stain pump is activated after approximately 50% of a glass
slide width has passed over the stain orifice.
• If so: Go to step 4.
• If not: Go to Chapter 8.4.
4. Check if the buffer pump is activated after about 3mm (1/8in) of a glass
slide has crossed over the buffer orifice.
• If so: Go to step 5.
• If not: Go to Chapter 8.4.
5. Check if the rinse pump is activated just as the leading edge of a glass
slide crosses over the rinse orifice.
• If so: You can now load smeared glass slides, see Chapter 5.4.
• If not: Go to Chapter 8.4.
