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.

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).
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. Can be sent and powered here without the metal chassis. Holds design data in memory. Compatible across several models with different ROM. The ROM generally has to match the lower ROM in the IMM card. This board fails about half as much as the IMM card.
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. They are combo boards and 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 to send the entire chassis unit.
Toyota 850 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 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 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. Errors and error causes will be similar. The Toyota 800 motherboard is a much larger board that goes in the center of the 800, and we do not repair this very old model.
Control Panel	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.
