Introduction Congratulations on your purchase of the DC16 Digital Combo press! This heat press machine has many exciting features, all of which are meant to help make your heat transfer pressing endeavors as successful and easy as possible. Please take the time now to thoroughly read through this manual to become acquainted with them.
Setup & Suggestions • Locate the press on a firm, sturdy work surface. It is recommended but not necessary to bolt the press to a workbench using the rear mounting holes on the base frame. • A stand on lockable casters is available from Geo Knight & Co or your distributor.
Normal Operation Normal Operating Mode The normal operating mode of the press will display the current actual Temperature at the top of the screen and the time setting elapsed time below temperature. The right side the screen will indicate the heating status by stating HEATING, READY, both of those words, or none at all, depending on if it is cooling down or heating up to the set temperature.
Setting Time From the normal operating mode, simply use the Arrow Keys ONLY to set the time. Do not touch the PRG key. Hold down either the Up or Down arrow key for more than 2 seconds and the time will increase rapidly.
Setting Pressure Pressure is set manually using the large black Pressure Adjustment Knob. There is one important rule of thumb when setting pressure: The press MUST LOCK IN PLACE when lowering and clamping the press. Do not simply let the platen rest on the pad. A good solid two-handed locking force is recommended when first doing transfers to insure good results.
Guidelines & Standard Settings The following information covers some basic guidelines for pressing, as well as some generic parameters for basic heat transfer applications. • When pressing shirts, it is often recommended that the shirts be quickly pressed for 2 to 4 seconds before transferring to remove wrinkles and water content.
ERR Mode During operation of the press, if there is a loss of signal from the temperature sensor wire, the ERR display will appear. This is a safety feature that will shut off the relay so the press will not overheat aimlessly without a temperature signal.
Using Attachments The main feature that makes the Digital Combo so versatile is the interchangeability of the heat platens. Because the heat platens are modular in their method of connection, one platen can be unplugged and another attached, in its place. These platens are “Hot Swappable”.
Attaching a heat platen The heat platen can be safely connected with the machine on. However, thermal gloves or oven mitts must be used when handling hot heat platens. • Lift the heat platen into the clamp linkage. Make sure the rear guide fork holds onto the guide pin in the back post of the frame.
Cap Hold-down Device (For Cap Attachment Only) There is a curved 1/2-moon cap holddown device for stretching the cap over the curved bottom table. Simply pull the back strap of the cap behind the pedestal and under the 1/2-moon shaped bracket. This will hold the cap in place for proper printing.
How to use the Cap Attachment The cap attachment works the same as a cap press. The only difference is that the swing-away style Digital Combo press allows complete access to the cap when the heat platen is swung out, as opposed to typical stand-alone clamshell cap presses.
How to use the Plate Attachment The plate attachment allows the operator to press down inside a dish or other indented object. Here are some tips for using the plate attachment: Use the large T-Shirt flat bottom table. Place the 3-sided aluminum tray on top of the T-Shirt table.
Programmable Presets How Presets Work There are 70 programmable presets in the controller. The operator can store a Temperature, Time, Prepress Time, and Pressure setting in each preset. When a preset program is loaded by the operator, the Current Temperature Setting, Time and Prepress Settings (if there is a Prepress setting in that preset) are updated in the normal operating mode.
Editing/Programming a Preset To edit a preset and change it’s values to your own desired settings, you simply use the TEMP key while in the SET preset mode. From the normal operating mode, press the PRG key. SET displays on the screen. Use the Arrow Keys to select the preset # you wish to edit.
A Walkthrough Tutorial for using Presets Here is a tutorial of programming 2 different presets, and then an example of using them in normal daily operations. Do this walkthrough to practice using presets. Part 1: Programming 2 different presets. From the normal operating mode, press PRG. SET appears. Use the arrow keys to select SET 01.
User Menus Entering the user menus & options There are many useful features beyond simply setting time & temperature, and storing presets. All of these additional features are available to the operator in the User Menus. To access the user menus, simply press TEMP & PRG at the same time from the normal operating mode and let go.
Recorded Pressings (User Odometer) There is an “odometer” that records pressing cycles done. This can be cleared and reset to 0 at any time when needed. The figure scrolls and it’s beginning and end are separated by a “-” sign. After entering the user menus (see top of page 18), Press PRG until REC displays.
Pressure Maximum To reset and redefine “9” for the pressure bar graph, use this calibration menu. Do NOT adjust this setting unless you are sure adjustments are necessary. Adjust the pressure of the machine so there is extremely heavy pressure when clamping and locking the press.
Keypad Beeper The keypad beep can be silenced if needed. After entering the user menus (see top of page 18), Press PRG until BEP displays. Use the arrow keys to set it to ON or OFF. Press PRG to move to the next menu item.
Finished Warning Beep The press can sound a beep on the last 3 seconds of the timer or Prepress timer countdown. This is useful if the press is automatic and the operator needs a warning that the press is about to finish, open, or pop-up dramatically.
Prepress Alarms The Prepress timer alarm can be adjusted for different beeping patterns. This allows for differentiating from the normal timer, and can allow the operator to have a short beep or a continuously repeating beep. After entering the user menus (see top of page 18), Press PRG until AL2 displays.
Parts / Maintenance / Misc Interchangeable Tables The lower table on the machine is interchangeable. Different sized optional tables can be obtained for various materials & handling requirements. The tables simply fit right onto the bottom pedestal. There are two steel pins that look like “bullets”...

Troubleshooting The following information attempts to address the most probable mechanical and user issues with the press. Most issues with heat transfer presses are application related. That is, they have to do with the results of a particular transfer application. For technical support on problems having to do with the final results of a particular transfer paper or media, please contact the supplier of that transfer media.
Troubleshooting (cont.) 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. 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.
