PLRElectronics Repair Portfolio

Embroidery Equipment List

Below is a small example list of a few of the electronics for embroidery equipment that PLRElectronics can repair.

It is advised to check with PLRElectronics if the damaged electronics are not on this list.

Name	Make	Model	Description
IMM Card	Tajima	TME-DC, TMFD	Lower daughtercard on the back of the machine's main power box. Small, is attached to the joint card with plastic snaps. Has a ROM and a battery backup and a DC-DC converter on it. Holds configuration information. May be malfunctioning if your machine has a startup initialization error of d-1.xx or d-2.xx. If battery is weak, may lose config info such as the proper stop position which will cause machine to rarely stop at zero degrees main shaft causing other errors. Repair of malfunctioning IMM boards is common, not counting the NiCd battery replacement that many owners seem to do themselves (odd sized battery); the battery is rarely an issue as it can hold config for awhile even without the battery, and a machine used daily or weekly without the battery can still go fine and not lose config (well, when the board is new).
IDM Card	Tajima	TME-DC, TMFD	The card in the control panel of DC machines. Has a ROM and battery backup and push buttons and LED screen and floppy drive. Can be shipped to our lab and powered here without the metal chassis, although preference always is that the entire chassis be sent, to minimize the number of technician hands on or around the board. Holds design data in memory. Compatible across several models of the DC, type 1 2 and possibly type 3, with different ROM. The ROM generally has to match the lower ROM in the IMM card or initialization will fail, or very strange errors will pop up continually when trying to use the machine. This control panel board fails only about a third as much as the IMM card does, but it does fail sometimes and so we like to see the IMM and IDM in pairs. (IMM is the little daughtercard on the back side of the machine, not in the control panel at all).
DU-10 Board	Tajima	TME-DC, TMFD, TME-HC	Metal box labeled DU-10 and heatsink/fan which houses the X & Y cards of the Tajima HC and DC series. Sometimes is on the older TMM series. The X and Y cards are identical and create a lot of heat each. Have a green or red light in the front of them to show status, which is continued in later Tajima models. If X or Y axis is not operating properly, or one of them simply not working at all, it's usually time to send the whole board in (well, both of them inside their heat sink chassis is preferred). They are combo boards and do a lot of things; they have their own power supplies and monitors onboard as well as irreplaceable computers and transistor section and internal trimmers to set power output. Generally repairable as the CPU is rarely afflicted. Recommended again to send the entire chassis unit.
Toyota 850/851/860 Mother Board	Toyota	850, 860	Main Motherboard for the Toyota 850 and 860 located in the back left of the machine (when facing the front). Perfect square shape with a dozen unique plugs around the edges and three ROMs and three CPUs down the middle. May have an optional daughtercard mounted over it which provides floppy drive ability for the later models. The board itself stands on nine plastic standoffs, and gets its power from an external supply (the heavy rectangular box that Toyotas always have near the machine). Can be set for single needle for the 851 variant. The board controls the XYZ motors and passes some signals between the control panel and the data ports. This board seems to be exposed to bio damage often, as the nearly complete metal enclosure around it with holes offers a temporary hiding spot for vermin, and then corrosion does its work over the years. Usually an internal connect error appears when the board is not functioning properly.
Toyota 820A/830 Mother Board	Toyota	820A, 830	Main Motherboard for the Toyota 820A and 830, which appear to be about the same machine but with different number of needles in the head. This is a rectangular board at the rear bottom of the machine, with two large white plugs in the back and a black metal cover. Every Toyota 820 based machine seems to pour gobs of machine oil on the motherboard, perhaps traveling down the cables, and so it may be messy. This board has two ROMs, two computers, and a built-in heat sink for a double row of small-size transistors almost down the middle, plus a distinctive large white rectangle socket for the large white plugs. The board sits over its own metal plate heat sink, on stubby plastic standoffs. The 820A and 830 motherboard appears to be the same with perhaps slightly different ROMs; however the 820 board (820 without the A) is incompatible and can be recognized by double blue lines around the main computers, instead of single (resistor arrays, technically). The 820A and 830 will also be all tiny chips, surface mount, while the 820 (without A) will be using large DIP style electronic chips. Errors from this board will be internal connect, internal com error, problems with controlling XY axis or problems with the solenoids. The board can overheat and shutdown if its not properly attached to its metal mounting plate with a metal screw in the side of the onboard heatsink.
Toyota 800/820 Mother Board	Toyota	800, 820	Main Motherboard for the Toyota 800 and 820. The Toyota 820 is nearly the same design and layout as the 820A/830 board mentioned above, but not compatible. It is recognizable from its large through-hole parts for its logic chips and double blue resistor arrays around the CPUs rather than surface mount parts like the later 830 boards. Errors and error causes will be similar to the 820a/830. The Toyota 800 motherboard is a much larger board than the 820/830, that goes in the center of the 800, and we do not repair this very old model.
Control Panel part #88620-4030	Toyota	850, 860	Control Panel for the Toyota 850 and 860. The Toyota 850 control panel board is identical to the 820A and 830 control panel circuit board, but different ROM; it can be switched but will need to run through a memory initialization. The 860 panel is paired with the optional daughtercard and is a completely incompatible board with anything but the optional daughtercard; it cannot go in a machine without daughtercard. The control panel card holds designs and communicates through the machine's data ports to upload new designs. RS-232 error is usually the fault of the control panel, and sometimes internal connect. There are dipswitches on these control panels and must be switched between floppy or wired communications mode. You can also enter a maintenance mode, and you'll have to from time to time as the toyota 850 and 830 programs are slightly buggy and when its nearly full, it will give false RS232 errors; always try a maintenance mode memory initialization in this case. We try to get both control panel and motherboard shipped to us, so there can be matching ROMs between all parts.
Control Panel	Toyota	820A, 830	Control Panel for the Toyota 820A and 830. The 820a/830 control panel looks similar to the 850 control panel, however it has a different ROM on the inside. This control panel holds the designs for machine in backed up memory. It will report Internal Connect for a number of issues; but the very first error is the one you should look at. Internal Connect will be a common second error if there is a critical error that it bypassed; this is meaningless, only the first error counts. If Internal Connect error is the very first error on powerup, either the control panel or the motherboard is at fault but by far it's likely an issue with the motherboard. If you get RS-232 errors on the control panel, you must first do a proper memory initialize in maintenance mode; the Toyota software is slightly bugged, and cannot recognize when its own memory is full; it will give this error rather than warn that running out of memory caused the problem. If you memory initialize and it still cannot download, at that point the control panel should be looked at by a repair lab. Maintenance mode and the memory initialize option is entered by flipping the very bottom dipswitch before powering up; flip it back when done.
Control Panel	Toyota	800, 820	Control Panel for the Toyota 800 and 820. This control panel is different than the newer 820a-830-850-860 control panels, as its a squat square almost, instead of a tall rectangle. This panel is also more limited in its memory, it can only hold one pattern at a time. The 800 and 820 use the same control panel but different ROMs that are incompatible. The usual problems are Internal connect error, Internal COM error. RS-232 errors are usually a problem with the 820 motherboard, not the control panel. The other two errors are usually the motherboard also.
Motherboard	SWF	ALL	101 Error. While the SWF control panel itself receives power from a 5 volt power supply, it requires that a power card elsewhere, for the main motor, power up properly or the control panel will immediately shut down with a Error 101: Main motor driver irregular signal, which cannot be bypassed. The control panel is usually fine and not at fault. This main motor card can also shut down if it sees strange signals from the main motor, or if input voltage is unstable. This card can usually be repaired, and is located in a large heat sink somewhere underneath the control panel side by side with XY cards. It is recommended to ship in all three cards as a unit, but the main power board can be removed and shipped on its own with additional disassembly. We do recommend the entire unit to be sent and we produced a video specifically to show how to remove and replace this module, due to popularity.
Control Panel	SWF	ALL	704 Error, Stuck at Loading System, Blank Screen. These errors are of the control panel and the entire control panel usually has to be sent to service these errors. It is rarely a straightforward repair, unlike a Tajima TMFX control panel, and so usually takes several days minimum plus a few days of stress testing depending on the exact error. There are more than one types of SWF control panels, to say the least, and we are not talking about the difference between a graphical and a standard text panel; the circuit board(s) on the inside are different depending on the year, making this not one of our favorites although one of our common repairs. Simply unplug the cables and send the entire thing in; please ship EXTRA EXTRA well against shocks. These control panels have very many internal cables and connections, and the control panel assembly jostling around in shipping will cause things to unplug themselves like a cell phone that has been dropped too many times. Well, whether its an SWF or TMFX control panel, both could use proper shipping and padding.
Power Supply Card-CX5601040000	Tajima	TMFX, TMFX2, TMEX1	No power to machine. No green light on lower control panel. Flickering light of control panel. Random software resets. XY cards and S card cannot turn green also. Motors do not move properly, all of them. Solenoids cannot fire. The main power card of the TMFX is the most important card in the machine. If you get any of these symptoms, first attempt a reinstall of the control panel; if there is no good effect, then you must ship in the power card and perhaps the other cards as well. The TMFX main power board is near the on-off relay, and is a metal cube at the bottom of the machine. We usually recommend that the entire cube be sent in, as all four cards can be checked for proper behavior in one of our machines here, and its also convenient to remove the block, and not go through extra assembly and disassembly. To save shipping, just the main power card can be sent in but usually introduces some delay as we double check all information with the customer and with the board; having the whole cube usually tells us a more complete story just by itself. The main power card, out of the four cards in that heat sink cube, is recognizable for having two large cables hanging from it, like rabbit ears. Three hex screws hold it to the heat sink; watch out for excessive heat transfer compound, this stuff gets everywhere. On the bottom of the heat sink is a fan; this may be removed, or just be careful about wrapping; use lots of bubble wrap in any event. The early version of the TMEX single-head also uses this board.
