The adapter between the power cord and the scanner does not work

When the power washer does not turn on, it is either due to no water flow or no electricity going to the power washer. In other words, either a water or electrical problem.
check water flow issue like this

1. The high pressure hose, spray gun and lance must be connected to the power washer.
2. The garden hose must be connected to the power washer using the garden hose adapter.
3. Turn the water completely on at the water faucet.
4. The power cord should not be plugged in.
5. Squeeze the trigger on the spray gun.
6. If there is water flow through the spray gun and lance shooting 10 - 25 feet, this confirms water flow is NOT the problem for the power washer not turning on.
7. If there is no water flow, perform the following troubleshooting procedures:
   a. Remove the lance, squeeze the trigger. If water flows, the lance is blocked. Use cleaning wire to clean the nozzle tip and try again.
   b. If no water flows with lance removed, turn the water off. Remove the spray gun from the high pressure hose. Turn the water on, if water flows, the gun is the problem. Reattach the gun, turn the water on and squeeze the trigger. Sometimes this unblocks the gun. If not, replace the spray gun.
   c. If no water flow with the gun removed, remove the high pressure hose, turn the water on to make sure there is no blockage in the hose. This is very unlikely but we need to make sure.
   d. If no water flows out of the water outlet, the quick connect garden hose adapter is problem. See Garden Hose Adapter troubleshooting.
8. For electrical solution check
9. The power switch was not turned on. Find the power switch and make sure the "-"side of the rocker switch is pushed down. "O" = Off and "¾" = On.
10. Next, make sure the power cord is plugged directly into an outlet and NOT into an extension cord. The directions do say not to use an extension cord.
11. Each time the power cord is plugged in to an outlet, the Reset button on the GFCI module must be pressed down to connect to electricity.
12. Check to see if the Reset button has been pressed.
13. Next, confirm the small plastic window below the Reset button shows RED in the window. The RED color is not a light but a RED screen that slides into the window when the Reset button is pressed down. Because it is not a light, it can be hard to see in low light. If you are unsure, press the TEST button down. If the GFCI was set and RED was in the window, you will hear and feel a "click."
14. The RED color must stay in the window once the button is released. This confirms there is electricity going to the power washer.
15. If the RED color goes away when the Reset button is released, there is NO electricity going to the unit. Try another outlet until the RED stays in the window.
16. Now if the unit turns ON for a second or two with the Reset button pressed and the power switched on, it is working as it should. All that is left to do at this point is to squeeze the trigger on the spray gun and the power washer will turn on. When the trigger is released, the power washer will turn off. This is due to the Total Stop System (TSS) that only turns the unit on when water is flowing through the power washer. When the trigger is released, water flow stops which the TSS sensed and immediately shuts the unit off. a) So to review, if the Reset button has been pressed and is holding and the power switch is ON, the power washer is supposed to start up for a second or two and immediately shut off. At this point all you need to do is squeeze the trigger; the unit will turn on.

If 22 is blinking in the Scanner LCDThe Transparent Materials Adapter (TMA) may be attached incorrectly or is broken.

1. Disconnect the scanner power cord.
2. Disconnect the TMA cord from the scanner.
3. Verify there are no bent or broken pins in the cord plug of the TMA. If the cord has bent or broken pins, it will be necessary to contact HP .
4. Reconnect the TMA cord to the scanner.
5. Perform a self-test on the TMA. Click here for instructions to do a self-test on the TMA (bps05670) .
6. Check that the TMA is properly positioned on the scanner glass; either reposition the TMA in the positioning plate or reposition the positioning plate on the scanner glass.
7. Reconnect the power cord to the scanner.
8. Attempt to scan.

If 22 "The scanner could not scan" displays on the screen and the Transparent Materials Adapter (TMA) is being used

1. Disconnect the scanner power cord.
2. Disconnect the TMA cord from the scanner.
3. Verify there are no bent or broken pins in the cord plug of the TMA. If the cord has bent or broken pins, it will be necessary to contact HP .
4. Reconnect the TMA cord to the scanner.
5. Reconnect the power cord to the scanner.
6. Perform a self-test on the TMA. Click here for instructions to do a self-test on the TMA (bps05670) .
7. Attempt to scan.
8. If the scanner still does not function, follow the instructions for resolving USB initialization and related communication errors (bps03850) .

If 22 "The Scanner could not scan" displays on the screen and the TMA is not being used

1. Disconnect both the scanner power cord and the USB cable.
2. Perform a self-test on the scanner if it has a built in self-test. Click here for instructions on performing a scanner self-test (c00030441) .
3. If the scanner passes the self-test, reconnect the USB cable and attempt to scan. If the scanner fails the self-test, it will be necessary to contact HP.
4. If the scanner still does not function, follow the instructions for resolving USB initialization and related communication errors (bps03850) .

1. Check that the power socket switch is on Make sure your scanner's power cord is securely connected to the scanner and a working electrical outlet.
   
2. If your scanner is supplied with a power adapter, make sure your scanner's AC adapter is securely connected to the scanner and a working electrical outlet.
3. Make sure that the power outlet works. (If necessary, test it by plugging in another electrical device and turning it on.)
4. Check that the power switch is on at the mains socket. If this is on, carefully check the power cable to ensure it is not damaged and remove then reseat it before attempting to turn the scanner on again. If your scanner has a power button, make sure that the button is depressed so it is turned on. Also, make sure that your outlet works and is not controlled by a wall switch or timer.
5. Power off the scanner at the mains socket. Unplug the power cable from the socket, then remove and reseat the power cable from the scanner's power cable port. Plug the scanner back in at the mains and ensure the socket is switched on.
   
6. If your scanner has a power button, does the power button depress when pressed? Press down firmly on the power button, if it is stiff and does not depress then there may be a problem with the button.
   
   
7. Connect the scanner directly to the mains - not via a surge protector or extension lead. If your unit is connected via a surge protector or a power strip/extension lead, connect the unit directly to the mains socket.
   
8. Try another suitable power cable. Check that other electronic devices connected to same power socket have power and try another mains socket and another power cable if necessary. Failing this try another suitable and known-working power cable. Depending on your scanner, a standard "kettle lead" or "figure of eight" power cable is used. If there is power to the scanner (indicated by an illuminated Start light), when a different power cable is used, then the fault is with the original power cable.
   

If the unit does not power on after following the checks above, contact Epson for support. If your scanner uses an AC adapter, then this may need to be replaced. If your scanner is over 12 months old, you can purchase a replacement AC adapter directly from Epson.

Your little friend Raphi either needs a new power cord or the power input connection at the back of the player needs re-soldering to the board. Basically, there is a partial break in the electrical supply to the DVD player. If you waggle the cable around a little where it enters the back of the unit, the light will probably go on and off.

It needs a little bit of testing to determine exactly where the break is, but it shouldn't cost too much to fix. Any local TV repair shop or a friend with a bit of electronics knowledge should be able to fix it.

Make sure you are plugging the power cord straight to the power outlet in the wall, bypass any surge device or power strip as it may cause power loss. If you have already tried this but still no difference, I suggest you contact Lexmark Technical Support to request for the power adapter. They can send you one for free. Thanks.

The correct part number for just the "brick style" power module (AC Adapter) for an HP Scanjet 3970 is L1970-80003. It is a specific 12V DC 2 Amp module. Today it can be purchased for $18.06 plus shipping from the HP Parts Store. However, if you are looking for just the power cord to your scanner's AC adapter, this brick style power module AC adapter does require a separate standard C13 detachable power cord to the specifications of your area, for instance, in the USA the power cord to connect the scanner to the power module AC adapter is part number 8120-6260, and it is a common power cord for monitors and computers. I learned all this because I had a scanner error message when I tried to use a different power module on the HP Scanjet 3970 when I lost the power cord to the original module. I hope this info helps somebody else, too.

Most likely cause of the "Scanner could not be initialized" error on the HP Scanjet 3970 is due to using an incorrect power adapter and cord -- the only power module and cord that work for the HP Scanjet 3970 are these part numbers: 8120-6260 for the power cord and L1970-80003 for the power module / AC adapter I hope this info helps you.

Your part should be Epson AC adapter A241B 15.2v 1.4A 30W. The power cord is a generic type cord common with printers and scanners, it should be easy to find if the power adapter doesn't come with one already. You may be able to find it cheaper somewhere online like Ebay.

go to ebay.com and look up your power cord you need
it should work
or go to a store and buy it

DO NOT use the HP power adapter that is 19V / 3.95A. That is too much power for the Scanjet, which is expecting 12V DC (and a much lower amperage). It's possible that hooking up this power adapter may further damage the electronics inside the scanner. If the second adapter has stopped working then it is possible that the internal circuit board has damage already and another adapter may not work. If you have access to a multimeter / voltmeter you could check for the 12V coming from the adapter. If you're getting the 12V, then the internal circuit board to the Scanjet is probably defective.
