Amplifier output chip in stereo is defective and unit gives error message of push power protect.
You need to replace output amplifier IC and check supplied voltages.

MY KDC-MP3342U SUDDENLY STOPPED WORKING! IT JUST KEEPS FLASHING ...'PROTECT'! REPEATEDLY! HELP!


Protect only comes on when an RCA is grounding out, speaker is blown or the speaker wires are shorting out. Check all your wiring on the head unit and see if all are insulated with tape or better and if there's an exposed wire, tape it up. Make sure that all connections are secured. Then double-check your fuses. Check all of your speakers and their wiring because going into protect mode is the units way of saying you have a problem with your speakers or wiring.

If your speakers and wiring all check out, disconnect your radio wiring harness, and then reconnect the harness. This resets your radio, and your radio should be working again.

If you need to enter the security code, try the default unlock code of 5227.

You can also try to reset your code if the default doesn't work. Try 'KCAR' or '3051'.

Canon Pixma IP4000 cyan ink will not flow even though I have repeatedly cleaned and deep cleaned and replaced ink tank.


If you have gone through the process of cleaning and deep cleaning, as described by canon, and you still get no ink flow after printing 2-3 pages, the print head needs to be replaced.
Here is WHO to contact and HOW to install the print head:
WHO: Purchasing a Print Head
You may purchase a print head* for this printer by calling 1-800-828-4040 Monday-Sunday 8:00 a.m. - 12:00 midnight. EST, excluding holidays. When calling, speak the term "order parts" when the speech routing system asks the reason for your call. You will immediately be routed to the Parts Desk for assistance. Be sure to have your model number (iP4000R) or part number (QY6-0049-000) ready for the sales person.

HOW: Install the print head and ink tanks correctly iP4000/iP4000R/iP5000

Seat the print head Below is the procedure for seating the print head and ink tanks:
  1. Power on the printer.

  2. Open the paper output tray and top cover.

    Note: Gently open the paper output tray while holding it.

  3. After confirming that the print head holder has moved to the center, open the inner cover.

  4. Remove the orange tape securing the print head lock lever, and raise the print head lock lever.

    Note: If the top cover is left open for more than 10 minutes, the print head holder will move to the right. If this occurs, close the top cover once and then re-open it.

  5. Remove the print head from its package and remove the orange protective cap.

    set_print_head_2.jpg

    <1> Electrical Contacts and Print Head Face's Nozzle Area
    <2> Ink Supply Filters

    Note: To avoid any damage, do not touch the print head face's nozzle area, electrical contacts, and ink supply filters. After removing the protective cap, set the print head into the print head holder immediately. Do not re-attach the protective cap after it has been removed.

  6. Set the print head into the print head holder, and lower the print head lock lever until a click sound is made.

    set_print_head_3.gif

    Next, install the ink tanks.

  7. Remove the cyan ink tank (BCI-6C) from its package. Pull the orange tape in the direction of the arrow to remove the wrap film completely.

    set_print_head_4.jpg

    Note: Remove the orange tape completely. If the orange tape is not completely removed, it may interfere with printing.

    <2> Removed incorrectly

  8. Hold the ink tank as shown in the image below. Twist the orange protective cap in the direction of the arrow, and remove it.

    Note: Remove the protective cap while holding it, so that fingers will not be stained by the ink.

  9. Insert the ink tank into the slot at the right end, and push down on the PUSH mark on top of the ink tank until a click sound is made. Install the other ink tanks in the same manner.

When a crank it the plug no.4 come out!!!And if i put it back when it's running it's fine as long as i dont push to hard on the throttle if i give it the plug will come out!!!craked threads??need help...


let me guess, it's a trition v8 engine? I'm right?! Common problem. Threads are stripped. Need to take it in. They can do several things to fix this problem, they are cheapest to most expensive. Retap the hole and fit larger plug in. Retap hole, making it wider then orginal then adding a ring, (sorry brain fart can't think of what it's called) so that the factory plug will fit again. Replace head. My suggestion is adding the ring. I want to say flex coil? Don't quote me on it cuz I don't do these projects. Hands aren't steady enough for this task.

It is flashing the word protect on the screen


You have a shorted speaker wire or a blown speaker. The unit is protecting itself from damage. Did you install it? if so, pull the deck and check your connections. If they all seem fine, disconnect one speaker at a time, and turn on the radio. Make sure the radio speaker wires are taped so they don't short and cause more damage. Test each speaker wire until you find which one is causing the problem. Now re-connect all the other speakers and test. Next, disconnect the speaker wire right at the speaker that's giving you a problem, tape it off, then re connect it to the receiver. now test again. If all is ok, you have a bad speaker, if not run a test wire from the radio to the possible bad speaker and test again. If the speaker plays, you know what the problem is, replace the bad wire. Most often it's a door speaker wire or a wire got pinched during installation and took a while to short. Hope this helps

Blank pages coming out of i850 with new printhead


Alarm / Power light flashes orange 7 times consecutively is a Print head error so it sounds like you did the right thing.

I would reseat the printhead along with each one of the ink cartridges. Make sure that you removed the tape from the bottom of each of the ink cartridges and try it again. After installing the new printhead, you should have run a printhead cleaning cycle immediately after installing.

Issue: Certain colors are missing or no ink prints on the paper
Solution: Install / replace the recommended ink tanks correctly i550 / i850

Untitled Document How to install / replace the ink tanks
The ink tanks suitable for the printer are as follows;


Black Ink Tank BCI-3eBK
Cyan Ink Tank BCI-3eC
Magenta Ink Tank BCI-3eM
Yellow Ink Tank BCI-3eY


Note: There are two ink tank label designs.
Operation procedures are shown with label design A.

labelsa.jpg Replacement Procedure


1. Check that the printer is powered on, and open the front cover. Wait until the print head moves to the center.

2. Remove the empty ink tank by pushing the tab on the ink tank.

Note: When doing this, do not remove the print head. When replacing multiple ink tanks, it is recommended to replace one at a time to avoid inserting them into the wrong slots.
(The image is an example using i850.)

removingtank850.jpg
3. Remove the new ink tank from its package. Pull the orange tape in the direction of the arrow to remove it completely, and remove the shrink-wrap film.

Note: Remove the orange tape completely. If the tape remains, printing may not be performed properly.

removingtape.jpg
Confirm that the orange tape is completely removed from the ink tank, as shown in image 1. If the tape is similar to the sample in image 2, remove the remaining portion of the tape so that it looks like the sample shown in image 1.

orangetape.jpg
(1): Correct

(2): Incorrect (where the arrow indicates)
4. Slowly twist the orange protective cap in the direction that the arrow indicates, and remove it. To avoid ink adhering to your fingers, brace the orange protective cap while removing it.

removecap.jpg


5. Insert the new ink tank to the print head by holding it at a slight angle.

Note: Confirm that the ink tanks are installed in the right order according to the labels on the print head.
inkorder.jpg
6. Press down on the top of the ink tank until a click sound is made.

7. Close the front cover. The next time the printer performs printing, it will automatically start print head cleaning. The power lamp will flash while cleaning is performed. Until cleaning completes, do not perform other operations.
