Overview

The DK20SP is a tabletop, air-operated automatic swing-away heat press engineered for production-focused workflows. Combining push-button activation with fully digital temperature and timing control, it delivers consistent results with minimal operator fatigue. The press features a 16" x 20" platen and a solid steel welded framework, providing durability and precision in a compact footprint.

Utilizing the same Digital Knight control system found in the DK20S series, the DK20SP offers a swing-away motion for full access to the lower platen, allowing safe and efficient garment placement. With up to 3,000 lbs of adjustable pneumatic pressure (air compressor required) and support for materials up to 2" thick, this press is ideal for high-volume applications where manual operation is no longer sufficient.

Positioned between Geo Knight’s heavy-duty manual presses (DK20/DK20S) and fully automated shuttle systems like the 394 Factory Press, the DK20SP offers an industrial-grade midrange solution for growing t-shirt printing businesses ready to scale their production capacity.

Success Starts with the Right Press

Success Starts with the Right Press

There’s a point when pressing by hand just doesn’t cut it anymore. Your arm’s tired, the orders keep piling up, and consistency becomes the name of the game. That’s where the DK20SP Industrial Heat Press Machine comes in. It’s the perfect mid-step between a heavy-duty manual and a high-end shuttle system, giving you air-powered automation in a compact tabletop setup.

With the DK20SP, all it takes is a button press. The swing-away design gives you clear access to the 16” x 20” platen, and once you’ve aligned your garment, you just hit the button and let the machine do the work. No tugging, no clamping, no holding it down. The press swings shut, applies up to 3,000 lbs of pneumatic pressure, and pops back open automatically when the timer's up.

It’s built on the same backbone as the DK20S series: Digital Knight controls, SuperCoil-Microwinding™ heater, and a solid steel welded frame. So if you’ve used the manual swing version, this will feel familiar (but a whole lot faster). You still get full digital control over temperature, time, and pressure. Want to run different materials back to back? Load up your 70 programmable presets and go.

This isn’t just about speed, it’s about precision. With a PSI range of 20–100, controlled by an onboard air regulator and gauge, you can fine-tune every press to match your material. Whether it’s cotton, performance blends, or something thicker, you’re getting exact, even results every time.

And speaking of thick, this press handles materials up to 2 inches. Add to that the All-Thread™ table loading system and interchangeable platens, and you’ve got a machine that adapts to your workflow, not the other way around.

The DK20SP hits a sweet spot for established shops: fully automatic control, small-shop footprint, and the kind of reliability you need when you’re churning out hundreds of shirts a week. If you’ve outgrown your manual press but aren’t ready to go full factory yet, this is your machine. Period.

Frequently Asked Questions

The timer does not start when I close the heat platen, or the timer does not reset when I open the press up.
  • There are several probable causes for this. The timer is activated by a micro-tilt sensor stuck to the pressure arm.
  • First: When the head of the machine is opened, the tilt sensor needs to be tilted slightly upward to signal the controller to stop/reset. When the head of the machine is closed, the timer sensor needs to be tilted downward (towards the floor) to signal the controller to start counting.
  • Second: Check the wire connection from the tilt sensor into the control panel. The timer and pressure signals go to a small black 6-pin connector on the top of the circuit board in the control box. Check to make sure this is firmly seated and plugged into the board.
The control displays “Err” when it first comes on, and I cannot set the temperature or use the press.

The “Err” message will display if the heating signal from the platen has been cut off, interrupted, or the heating sensor has failed.

First, check the lime green temperature connector that plugs into the digital control. At the top of the controller, there is a green connector that plugs in with two small wires. This is the temperature sensor wire. Check to make sure it is properly seated.

If, after unplugging and plugging the lime green connector, the “Err” message still appears, unplug the green connector and remove the two tiny wires from the lime green plug. Cut them back 1/4”, strip them so they have new connections, and reconnect them to the lime green plug so they are screwed in tightly and cannot pull out. Plug the green plug back in and turn the press on.

I press the keys on the keypad, and there is no sound or response from the controller.

Check the connection of the keypad to the controller. This is inside the top panel.

  1. Unplug the power cord.
  2. Remove the two screws in between the clamp/linkage that hold down the top panel.
  3. 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.

The gas springs are not lifting the head as easily as when the press was new, or the gas springs have lost their pressure.

After a large volume of use over an extended period of many pressing cycles, the gas springs will slowly lose their original force.

These hydraulic lifter springs are extremely easy to replace, and are surprisingly similar in cost—or even lower—than conventional mechanical springs. Contact the factory for replacement gas springs if the machine is no longer able to keep the platen open. Note: The gas springs must have the silver rod face down, and the black tube face up.

The press has shut off and will not come back on after checking the power cord.

Test for power coming from the back side of the power cord inlet socket. Then, test for power coming from the back side of the on/off switch. Finally, test for power coming to the end of the black and white wires that run from the on/off switch into the control board.

This will help narrow down which power-handling component needs replacement. The RPK-DKPWR is a common replacement kit that includes all these components.

I pressed a transfer upside down. The inks and transfer material have burned onto the heat platen.

Cool the press down. Using a non-abrasive 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're still unable to remove the transfer material, obtain Teflon heater block cleaner from the factory.
