How to solve common problems When stained blood smears are not of the desired quality, the first tendency is to assume the fluids or the slide stainer is at fault. However, other factors could be the cause of the poor quality of stained blood smears. The following list can help isolate the problem prior to checking the system: • Was the blood thoroughly mixed before making the smear? • Is the blood old or does it contain an incorrect anticoagulant? • Is the blood smear too thick, too thin, or does it spread unevenly? • Is the feathered edge of the smear end at least 1.5cm from the end of the glass slide? • Was the blood smear thoroughly dry before staining? • Are the glass slides clean? Even new glass slides are not necessarily clean. • Are the glass slides flat? Variable thickness of a given glass slide can cause uneven staining. • Is the microscope clean and adequately illuminated? A dirty microscope or inadequate lighting can give the impression of a poorly stained blood smear. Checking the adjustment of the sensing switch fingers Load 4 spare glass slides into the grooves of the conveyor spirals. Watch the system perform the staining. Has the stain pump activated after approximately 50% of a glass slide width has passed over the stain orifice? YES NO Has the buffer pump activated after about 3mm (1/8in) of a glass slide has crossed over the buffer orifice? NO YES Has the rinse pump activated just as the leading edge of a glass slide NO crosses over the rinse orifice? YES Adjust the sensing switch fingers You can now load smeared glass slides Refer to Instruction Manual for details SIEMENS Unrestricted | Published by Siemens Healthcare GmbH © Siemens Healthcare GmbH, 2022 Master Template Effective Date 10 Aug 2021 | HILS 2224 Healthineers Page 3 of 6 Job Aid | Hematek 3000 Maintenance Effective Date: 14 Oct 2022 | HOOD05162003307412 Problem: Poor staining or incorrect pump volumes When glass slides are not satisfactorily stained or pump volumes do not appear to be optimum, check the staining process first. If necessary, correct and verify the pump volumes. Check the staining process When glass slides are not satisfactorily stained or pump volumes do not appear to be optimum, check the staining process first. If necessary, correct and verify the pump volumes. Note: After completing each of the following steps, load several spare smeared glass slides and check the result. If any of these steps corrects the situation, you do not need to correct the pump volumes. 1. Raise the lid. 2. At the right side of the system, observe the circular bubble level to check if the leveling feet have been properly adjusted and the system is level. The bubble in the circular bubble level should be centered within the inscribed circle. If not, level the system using the two leveling knobs located under the instrument at the right and left corners. Refer to Instruction Manual for details. 3. Make sure the Hematek Stain Pak has been vented. 4. Clean the platen. 5. Make sure that there is no residue in the two mixing grooves. 6. Clean the drain troughs. 7. Check the adjustment of the sensing switch fingers. 8. Replace the pump tubing. 9. Replace the underplaten tubing. 10. If none of these checks solve the problem, correct the pump volumes.

An adjustment knob that controls the rotating speed of the respective pump is located next to each pump assembly. The volume of fluid delivered by each pump can be adjusted by turning the respective adjustment knob clockwise to increase the volume or counter-clockwise to decrease the volume. Each adjustment knob features a centering catch which provides a central reference point. Pump Assemblies and Adjustment Knobs Pump Cap 3 2) Pump Arm (2 +2 3 Pump Arm Handle 1 4 . +2 Adjustment Knob 4 +6 Volume Increments 1. Volume increments are marked on each adjustment knob. 2. The stain-to-buffer ratio is adjustable to provide ratios of 1:2 to 1:3. 3. This feature allows the user flexibility in obtaining the desired stain results. A small change in the stain-to-buffer ratio can result in either lighter or darker staining.
