WARNING
SOLVENT SPRAY. THE UNDERSCREEN CLEANER SPRAYS A FINE JET OF
SOLVENT SOLUTION ON TO THE CLEANER. APPROVED PROTECTIVE
CLOTHING SHOULD BE WORN.
CAUTION
RECOMMENDED SOLVENTS. ANY SOLVENTS USED MUST COMPLY WITH
LOCAL ENVIRONMENTAL GUIDELINES. DEK RECOMMEND USING SOLVENTS
THAT ARE ENVIRONMENTALLY FRIENDLY, IE CFC FREE AND WATER BASED.
SOLVENTS USED MUST HAVE FAST EVAPORATION RATES AND FLASHPOINT
SPECIFICATIONS GREATER THAN 39ºC.
CAUTION
SOLDER PASTE AND SOLVENTS. WHEN USING OR HANDLING ANY SOLDER
PASTE OR SOLVENT FORMULATION THE MANUFACTURERS’ RECOMMENDED
SAFETY PRECAUTIONS MUST BE STRICTLY ADHERED TO.
External Solvent
Tank
The software needs to know the weight of the external solvent tank when fitted
with an empty container and when fitted with a full container of the solvent to be
used.
NOTE
Due to solvents having different gravities, the weight must be re-calibrated
when changing solvents.
To calibrate the software carry out the following procedure:
1. Ensure that the external solvent tank is fitted with an empty 5 litre container.
2. Select Maintenance.
3. Select Calibrations.
4. Select Solvent.
5. Select Set Solv Empty.
6. Confirm by selecting Yes.
7. Replace the empty 5 litre container with a 5 litre container full of the solvent
to be used.
8. Select Set Solv Full.
9. Confirm by selecting Yes.
10.Select Exit.
11. Select Exit.
12.Select Back.
Paper If paper counting is enabled, the software needs to know the paper roll length
when first fitted to the under screen cleaner.
NOTE
The length of the paper roll is printed on the paper roll wrapping.
To calibrate the software carry out the following procedure:

Rising Table Style 1
Print Height Print reference height is the height to which the rising table is taken to achieve
board clamp to screen contact at zero board thickness. Print height is the height
the rising table is taken to print the product and is calculated as the print
reference height minus the board thickness and print gap. This calibration
accurately sets the board to screen ‘set contact height’ and ensures constant
print pressure is applied. Deterioration in this calibration may result in inconsist-
ent print pressure thereby effecting the print quality.
1. Ensure that a screen is fitted in the machine.
2. Select Maintenance.
3. Select Diagnostics.
4. Use Next or Previous to highlight Rising Table.
5. Select Select Module.
6. Ensure that Home Rising Table is highlighted.
7. Select Run Diagnost.
8. Use Next or Previous to highlight Set Reference Print Height.
9. Select Run Diagnost. The following window is displayed:
10.Select Confirm. The following window is displayed:
11. Open the front printhead cover.
12.Check the gap between the top of the transport rails and the screen. The
correct print height is when the top of the transport rails is just touching the
screen.
13.Use the Incr. or Decr. button to adjust the displayed dimension.
14.Select Move.
15.Repeat Steps 11 to 13 until the top of the transport rails are in contact with
the screen, without force.
16.When the correct height has been achieved, select Set Height.

Please confirm the following:
There is a screen loaded.
There is NO board loaded.
The aim of this calibrationisto set the elevation of
the rising tableto the point where the closed board
clamps are just in contact with the stencil.
Whilefoil-less clamps orsnuggers are beingused,
ensure they have been adjusted to bring their top
surface levelwith
the top surface of the board.
Upon completion of this calibration, the Squeegee
Reference Height shouldalso be calibrated.
