The problem is with printer. It is either a gear alignment is needed or the printer detector is already defective. There is also a case that an I.C. for the printer on its mainboard is defective. The best solution is to contact your authorized service center on your area.

Button problem


What those keys on the membrane pad have in common is pin 18 of the keypad matrix. See page 20 of the Service Manual Membrane Pad Continuity Checks. Do you know how to make continuity readings with an ohm meter? Follow the SM to power down the machine and remove the console to get to the console ribbon cable plugged into the Control Board. Very carefully remove the ribbon cable by squeezing the ribbon cable retainer plug ends to release the retaining plug which will then slide up the ribbon cable as in the pic's. Don't pull on the ribbon cable until you slide the retaining clip up the cable. I would check for any corrosion path issues between the pins on the ribbon cable and the mating socket on the Control Board. Follow the service manual for the continuity checks for the keys mentioned. The ribbon cable has black conductive pads on one side of the cable and you may need helper to make these measurements. With no keypad press you will read an open. Between a few of the keys I pressed for measurements I measured 30 ohms to 90 OHMS.
Do not make any measurements on the control board with the OHM meter. Here is a pic of the retraining clip that latches to the socket on the control board.
If the key press readings are similar to my readings for the effected keys I would try reseating the ribbon cable back in the socket on the control board then latch the retaining clip into the socket on the control board, power up the washer and give it a try. If the community checks on the keys in question read similar to mine not open under key press and the ribbon cable socket looks clean with no corrosion then I would suspect a Control Board issue.

If you feel uncomfortable with this I would call in a authorized repair service. Good Luck.

Intel D845GBV will not boot into Operating System ,Win XP Pro


Still have that Windows XP Pro full installation disk, that you used for this harddrive?

First:
Make sure all power cables from the power supply are connected.
You have a motherboard, (Intel D845GBV), that has a Socket 478 processor socket, and uses Intel Pentium 4 processors.

Computer Unplugged from power! Touch the metal frame of the computer case to relieve your body of static. Work on a table. IF you get up for any reason, then return, Make Sure you touch the metal frame, BEFORE you reach inside.

1.Make SURE the 4-pin ATX power cable from the power supply, is plugged into the 12 volt ATX connector on the motherboard.

[12 volt ATX connector on motherboard:
Bottom LEFT corner of the processor socket. You are looking at the motherboard with the processor at the top, and the ram slots to the right]

2.Make sure the 40-pin flat ribbon interface cable, is plugged into the harddrive correctly.

There is a faint red stripe along one edge of this flat ribbon cable. The red stripe designates Number 1 pin. (There are 40 pins on the back of the harddrive. [39 actually. One pin is blocked out]

As you view the back of the harddrive, the 4-pin Molex power cable, plugs into the right side. (All the way to the right)
The 40-pin flat ribbon cable plugs in to the left of the power cable.

Number 1 pin of the flat ribbon cable, is next to the power cable connection.

The red stripe, will now be close to the power cable connection on the harddrive, when the flat ribbon cable is plugged in correctly.

3.Make sure the 4-pin Molex power cable is plugged in firmly into the harddrive.

4.Check all power cables to the optical drive/s, and the main power cable to the motherboard.
[20-pin ATX power cable. To the right of the ram slots]
Now, close the computer case, plug the computer back into power, WAIT 1 minute, turn the computer on.

As SOON as the POST screen goes by, start tapping on the F2 key. You are going into BIOS Setup.

You should now be on the main menu in BIOS Setup. You can no longer use your mouse, you have to use your keyboard to get around in BIOS Setup.

At the top you will see headings in the header bar. Maintenance, Main, Advanced, Security, Power, Boot, and Exit.
Use the Right Arrow key and highlight Boot.
Press the Enter key.

Use the Down Arrow key and highlight Boot Device Priority in the drop down submenu. Press the Enter key.

Use the Down Arrow key and highlight ATAPI CD-ROM. Press the Enter key.

Now press the F10 key.
If Yes/No comes up, use the appropriate Side Arrow key, (Left or Right), and highlight YES. Press the Enter key.

IF Y/N comes up, press the y key for YES.
(It isn't a capital Y. The capital Y is shown for clarity. Do Not press the Shift key, and the y key. Just press the y key)
Now press the Enter key.

(F10 is to Save Changes. Y is Yes you want to save changes. The Enter key executes the command)

Your computer will now restart. You need to have that full installation disk in your optical drive. (CD/DVD drive)
Your computer will now boot from the full installation disk in your optical drive.

If your computer goes past booting from the installation disk, because you did not get it in there in time, don't worry.

Just press the CTRL key, ALT key, and DELete key, AT THE SAME TIME. (Not shouting)
This will restart your computer, and it will boot from the Windows full installation disk.

Grunting noise?


If your machine is a Brother 4100 you can clear the drum message by pulling the drum out of the machine and then pressing the clear button. The display will ask if a new drum is the be installed. Press the number 1 to say yes. Reinstall drum. This resets the drum counter.

As far as the grunting sound, that may be caused by a tight or jammed toner cartridge. Try changing that out.

Hope this helps.
