Troubleshooting (cont.)
Q. I press the keys on the keypad, and there is no sound or response
from the controller.
A.
Check the connection of the keypad to the controller. This is
inside the top panel. Unplug the power cord. Remove the two screws in
between the clamp/linkage that hold down the top panel, and carefully
lift the panel up and look inside at the digital controller. The keypad
connector passes in through the top panel. It should wind around the
first circuit board and be seated fully into the connector. Check the
black keypad connector that plugs into the circuit board to see if it has
pulled apart. Also check the area where the keypad connects to the front
membrane to see if the leads have been damaged. The membrane keypad
may need to be replaced.
Q. The gas springs are not lifting the head as easily as when the
press was new, or the gas springs have lost their pressure.
A.
After a large volume of use, and over an extended period of
time of many, many pressing cycles, the gas springs will slowly loose
their original force. These hydraulic lifter springs are extremely easy
to replace, and are a surprisingly similar or even lower cost than
conventional mechanical springs. Contact the factory for replacement
gas springs if it is not able keep the platen open. The gas springs must
have the silver rod Face Down, and the black tube Face Up.
Q. The press has shut off, and will not come back on after checking
the power cord.
A.
Test for power coming from the back side of the power cord inlet
socket. Test for power coming from the back side of the on/off switch.
Test for power coming to the end of the black & white wires that come
from the on/off switch into the control board. This will narrow down
which power handling component needs replacement. RPK-DKPWR is
a common replacement kit that includes all these components.
Q. I pressed a transfer upside down. The inks and transfer material
have burned onto the heat platen.
A.
Cool the press down. Using a nonabrasive detergent or cleaner,
thoroughly scrub the heat platen surface. Do not use an abrasive
scrubber, or a pad that will scratch the Teflon coating of the platen. If
you are still unable to remove the transfer material, obtain teflon heater
block cleaner from the factory.
