Tajima TME-DC Electronics
{{#invoke:Infobox|infobox}} The Tajima TME-DC was one of the longest produced Tajima models.
TME-DC Electronics
The Tajima TME-DC machine electronics consist of the main power box (underneath the machine), the control panel, DU-10 (XY) and various other small boards such as head cards, joint cards, and communications cards.

List of boards generally found on the Tajima TME-DC models:
Control Panel
The TME-DC Control Panel houses the Tajima TME-DC's main computer boards which include the control panel, LCD screen, IDM card and Floppy Drive or Floppy To USB unit. The Control Panel can be opened by hand from the back with the 2 flat head hand screws.
It is preferred that the entire control panel be shipped when undergoing repairs on any of the Control Panel component.
DU-10
The DU-10 unit precedes the previous DU-6, DU-7 and DU-8 models. The DU-10 contains 2 identical cards. The cards in the DU-10 unit are the X and Y movements for the Tajima machine.
The X and Y cards/cables can be swapped for testing purposes. Be sure the machine is turned off when testing.
The X and Y cards also have potentiometers for increasing the power to the machines motors. These potentiometers should never be touched unless by a technician. Also, these potentiometers are set at the factory or at installation and are set specifically for the X or the Y motors both of which need different power input.
Errors
When the X or Y boards start to go back either an amber light will be seen on the box or the movement either direction might sound very rough. The embroidery might not look as good or it might look scaled down on one axis. The pantograph might be easy to move in one direction or another while the machines power is still on.
IMM Card and IDM Card
The IMM Card and IDM Card are communication cards between the control panel and the main control box. If the machine does not boot up but displays info on the screen such as software version numbers, then the IMM or IDM cards might need to be replaced or repaired.

Tajima part number ED5601000000
There are two circuit boards responsible for most errors which are the Tajima IDM and Tajima IMM and IMM2 cards, in the control panel and in the lower back of the machine, respectively. There are several versions of these boards for the TME-DC Type 1 (Green) and Type 2/Type 3 (White control panel). Other errors on the Tajima TMFD/TME-DC type of machine are due to defective brake boxes (attached to the main motor of the machine) and the main motor itself in the type2 and type3.
The Tajima TME-DC embroidery machine also has a floppy drive unit which can become defective over the years, and the DU-10 type of XY control boards.
Errors
Errors include the d-1.xx, n-1.xx errors, where the control panel becomes frozen. Other errors include the color change function acting erratically, the main motor unable to function, the brake box not being able to stop the shaft at the proper location (or hold it), the main motor not functioning at all due to a E-002 error on the newer type brake box, and the mentioned floppy drive problems.
The d-1.00 error, d-1.01 error, d-1.06 error, can be about any number between 1.00 and 1.14.
The DU-10 cards, which control the Tajima's X and Y-axis, can also degrade and be damaged; if there is jerky movement or the lights on each card are orange or red, please let us know.
PLRElectronics also states Send your Tajima IMM card or IDM board in for repair today!
Color change card
Power to the color change motor. Also reads the color change potentiometer and some solenoids.
Head card
When head cards start to go bad, the machine might report false thread breaks. Before replacing or repairing its recommend to clean the connectors where the check springs touch the copper stopper.
