Main motor failed--check hook system

I assume this is a message you've got on your machine - you dont state which model it is, but there are only a few Berninas that do this and I'd guess its one of the new 820/830 or 530/550/580 range ??? The message is telling you that there's been a jam-up of the mechanics and the main motor has been overloaded - it will have turned itself off, so isn't, hopefully, a fatal message. You need to check the hook/shuttle area ... where the bobbin case is fitted - is the bobbin case properly in place ... indeed, did you forget to put one in !!! Check if there is a big pileup of thread around the hook/shuttle - take out the stitch plate and check underneath for blockages. One prime candidate is sewing pins that can get dragged under the foot and in through the stitch-plate - have a thorough look around and make sure that you can turn the handwheel freely, but DO NOT force it if there's a jam-up - you could damage something. Get back to me with more details of which machine it is and what you were doing, if you cant resolve this yourself.

I have an Infocus 640 that I'm thinking of repairing. It won't power on correctly. If I hook up a regular power cord to the back and bend it slightly and press the power button, the unit will power on...

firstly why not just resolder the main connector on the pcb of the 640 unit. then check if your problems will be solved.

Otherwise look at the part number of both power supplies and see if they are the same.

Heating problem with one split in a double split system

Either the board or capacitor have failed. If the motor is HOT the motor could also be the problem. in oder to tell if it is the board you will have to check to see if there is power coming fromthe board at the place where wires hook up. If power is there then it is either the motor or cap.

I have a DDL-5550N-7. It is connected to a Juki SC-1 type FB. Everytime I push the pedal its stops, beeps and on the screen it says E 7 660865. It will not work after that. I need to disconnected and...

Per the SC-1 Engineer Manual:

Error Code E7
The motor has locked. (The motor fails to rotate with controlled even when the motor has been driven.)

Check whether the sewing machine head has locked. (Is is possible to trun the pulley lightly by hand?) ** Correct the swizure of ther machine head.

Check whether the tread has been tangled in the pulley of the sewing maichine.

Check whether the thread has been tangled in the motor pulley shaft.

Check whether the thread has been caught in the hook.

Check whether the proper amount of oil is supplied to the hook.

My guess is your hook and cutter are stuffed with thread and thread dust. Remove the cover plate (2 screws) and the feed dog (2 screws) and carefully clean the junk out. You also likely have thread wrapped aound the shaft behind the bobbin assembly. I use a seam ripper to get that thread out.

Laserwriter 12/640 PS

hello the printer paper pick-up rollers are bad. this why you caanotuse the pick tray. the solution now is to set the printer to default and clear allstuff off memory. read the instruction below: LaserWriter 12/640 PS: IBM PC or Compatible Troubleshooting This article explains IBM PC or Compatible Troubleshooting. A message on the screen says the printer can't print. If you get such a message, try the following steps. Make sure that the printer is turned on. Check the network or parallel cables. Make sure that the PostScript printer driver has been installed. Nothing is printed; no paper comes out of the printer. If you don't get any response from the printer when you try to print a document, try the following steps: Check the Installed Printers list to see that your printer is selected. Try printing the document again, but choose Download PostScript Error Handling in the Printer Setup PostScript Options dialog box. Check the Paper Out light. If it is on, add paper and replace the paper cassette. If it is blinking, make sure the paper cassette is securely in place. Check for a paper jam. Check the printer cables. Check the position of the port communication switch. The port may have been turned off or the Interpreter settings may not be correct. Reset the communications settings to their factory default values by setting the communication switch to the Reset (out) position. Turn the printer off and back on again. Set the communication switch to the Normal (in) position. Turn the printer off and back on. Check the startup page. Reinstall the printer driver. For Windows 95 users, check the following additional item: Open the Printer folder, select the printer, and click Properties. click the PostScript tab and click the Advanced button. Make sure that ASCII data and "Send CTRL+D after job" are selected. For Windows 3.1 users, check the following additional item: Open the Printer Control panel, select the printer, and choose Setup. Select the PostScript tab in the Properties dialog box. Make sure that Protocol Options is set to Default if using the parallel port, or None if printing via NetWare. Sometimes Printing the First Page Takes Longer than I Expect The LaserWriter 12/640 PS automatically goes into an energy-saving mode after it's been idle for a while. When you print while it's in this mode, the printer takes about a minute to warm up before it can print the first page. The printer is properly connected and configured, but printing is garbled or displays unwanted characters. Check the communication switch and make sure that the Interpreter is set to the correct value. If you are printing a PostScript document, the Interpreter mode should be PostScript or AutoSelect.

My system locks up when I attempt to download images from my PDC 640 camera.

While it appears that the system is locking up, the actual problem is that a message prompt in the PhotoMAX 2.0 software is hiding beneath other open windows and needs to be answered before proceeding. In this instance, the PDC 640 TWAIN Driver window has been preset to always be the "top" window, obscuring any other windows that may be open behind it. The PhotoMAX 2.0 window must be "active" (or "brought to the top") to answer any message prompts. Once the message prompt is answered, you will be able to download images. To deactivate the PDC 640 TWAIN Driver window's "Always on Top" preset: 1. Launch the PhotoMAX application. 2. Select Get Photo. 3. Select Camera or Scanner. The Acquire From window appears. 4. Select Twain device and click OK. The Select Source window appears. 5. Highlight PDC 640 and click Select. The album window appears next, followed by the PDC 640 TWAIN Driver window. 6. Right-click on the PDC 640 TWAIN Driver window and deselect (i.e. uncheck) "Always on Top". To move the PhotoMAX 2.0 window forward: 1. Launch the PhotoMAX application. 2. Click on Get Photo. 3. Click on From Album. 4. When the album opens, answer YES to the question "The contents of this album have been changed. Do you want to save the changes?". 5. Click on the Acquire icon at the top of the album window to select the PDC 640 camera and download the thumbnails from the camera. Your system will no longer appear to lock up.
