I'm not sure why you want to access the sensors, but the only manual I know of for that machine is here. If you're trying to avoid the false out of paper error message that shows on your machine, you need to do a forced reset by following the instructions in the second to last post in this thread.

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.
If I've managed to answer your question or solve a problem, please take just a moment to rate this post....thanks!

Location of airbag sensors


Are you talking about impact sensors? Two are located on front right and left frame support. They are accessible from the bottom but its easier to take the bumper off to gain easy access to them. Another two are locates on bottom of B pillar around the area where the driver and passenger seatbelt tensioners are. You have to remove the door seals and plastic cover of the B pillar to gain access to them. Last two are mounted below C pillar behind the seat back cover. You have to remove cushion and back piece to gain access to them. Some people say there are versions without the sensors under C pillar tho, but I worked on one that had those sensors.

Where is the crank shaft sensor located on a ford taurus 2005.


  • Disconnect the ground battery cable using a wrench to hold the terminal bolt in place as you loosen the retaining nut with another wrench.

Locate the accelerator cable next to the throttle assembly towards the back and top of the engine and remove the shield. Pull the retaining pins using a pair of slip joint pliers if necessary.

Remove any other accessories that might interfere with the removal of the camshaft sensor like wiring harness, spark plug retainers or engine cover, depending on your particular Ford Taurus model.

Move the fuel-injectors wiring harness off the valve cover studs as well to gain access to the camshaft sensor if necessary.

Locate the camshaft sensor around the top of the engine. For more information, see the Resources box at the bottom of this article.

Unplug the camshaft-sensor electrical connector by pressing on the lock tab and pulling the plastic connector off the sensor.

Unfasten the two sensor mounting screws using a Phillips screwdriver and remove the sensor from the engine compartment.

Installing the Camshaft Sensor

Position the new camshaft sensor in place and start the two mounting screws by hand to avoid damaging the threads.

Tighten the two mounting screws using the Phillips screwdriver.

Plug the camshaft-sensor electrical connector.

Realign the fuel injectors' wiring harness over the valve cover studs.

Install any other accessories you had to remove to gain access to the camshaft sensor like wiring harness, spark plug retainers or engine cover.

Replace the accelerator cable shield if you had to remove it. Use the slip joint pliers if necessary.

Connect the ground, battery cable using one of the wrenches to hold the terminal bolt in place and tighten the retaining nut with another wrench

HP DESKJET 1180C


HP Deskjet 1180c and1220c Professional Series Printer and HP Deskjet 9300 and 1280 Printer - Troubleshooting a Blinking Print Cartridge Light Introduction The Print Cartridge light continues to blink with both cartridges properly installed and the Access Cover (also known as the top cover or lid) closed. Instructions The blinking Print Cartridge light may be caused by a faulty cartridge, the plastic case of the printer being dislodged or slightly out of position (which prevents the Access Cover from seating properly), the Access Cover sensor (also known as the top cover sensor or lid sensor), or by the actuator on the Access Cover. Follow the steps below to resolve the issue.
  1. With the printer turned on, open the Access Cover. The carriage will move out of the capping station and stop at one of the cartridge status icons located inside the printer under the Access Cover. The yellow arrow on top of the carriage will point to one of the cartridge status icons to indicate a good, empty, or faulty cartridge. See Figure 1 below.
    1. If the carriage stops in the cartridge’s OK position, indicated by the happy face in Figure 1, continue with Step 2.
    2. If a problem is indicated with one of the cartridges, remove the cartridge and verify that the cartridge part number is correct. The black cartridge part number is 51645A and the color cartridge part number is C6578A or C6578D.
    3. If the cartridge part number is correct, clean the electrical contacts on the cartridge with a soft, lint-free cloth. Do not touch or wipe the nozzle plate.
    4. If a faulty cartridge is still indicated after verifying the cartridge part number and cleaning the contacts on the cartridge, replace the cartridge.
    5. After replacing the cartridge, turn off and then turn on the printer to clear the cartridge error from the printer's memory. If the cartridge error cannot be cleared, the printer will require repair. If the carriage stops in the cartridge’s OK position, indicated by the happy-face in Figure 1, continue with Step 2. NOTE: The printer checks the status of both print cartridges before printing. Both the black and color cartridge must be functional and installed in the printer in order to print.
    Figure 1: Cartridge status icons c00001225.jpg Icon/Drawing Problem identified by the symbol Solution c00001226.jpg The color cartridge is missing, improperly installed, defective, or the wrong print cartridge is installed. 1. If there is no color cartridge in the cartridge cradle, insert a color cartridge.

    2. If there is a color cartridge in the cradle, remove the color cartridge and firmly reinsert it.

    3. Check to make sure the color cartridge is appropriate for the printer.

    4. If the problem persists, replace the color cartridge. c00001227.jpg The black cartridge is missing, improperly installed, the wrong print cartridge, or is defective. 1. If there is no black cartridge in the cartridge cradle, insert a black cartridge.

    2. If there is a black cartridge in the cradle, remove the black cartridge and firmly reinsert it.

    3. Check to make sure the black cartridge is appropriate for the printer.

    4. If the problem persists, replace the black cartridge. c00001228.jpg The color print cartridge is running low on ink. Replace the color print cartridge with a new color print cartridge. c00001229.jpg The black print cartridge is running low on ink. Replace the black print cartridge with a new black print cartridge. c00001230.jpg None. The print cartridges are working correctly. None. The print cartridges are working correctly.
  2. Close the Access Cover and wait for the printer to initialize. If the Print Cartridge light is still blinking, remove the Access Cover by following the steps below:
    1. Open the Access Cover and hold it open.
    2. Dislodge the Access Cover from the hinges with a sharp blow to the hinge area of the Access Cover and then remove the Access Cover.
  3. Install the Access Cover by following the steps below:
    1. Align the hinges on the Access Cover with the hinge pins on the printer.
    2. Push down firmly on the Access Cover until the hinges snap into position.
  4. Close the top cover and wait for the printer to initialize. If the Print Cartridge light is still blinking, the printer case may be dislodged or slightly out of position. To restore the printer case to the proper position, squeeze the printer by applying pressure to the front and back pressure points shown in Figure 2. Figure 2: Pressure points c00006497.jpg Firmly squeeze the pressure points on the printer case as shown in Figure 3. If the Print Cartridge light continues to blink, continue with step 5. Figure 3: Squeezing the pressure points c00006498.jpg
  5. If the Print Cartridge light is still blinking, push down firmly on the center of the Access Cover (the extra pressure may engage the sensor). If the Print Cartridge light quits blinking, remove the pressure from the Access Cover to see if the Print Cartridge light starts blinking again. Re-apply the pressure to the center of the Access Cover to see if the Print Cartridge light stops blinking again.
    1. If the Print Cartridge light quits blinking with pressure applied, the Access Cover is faulty and should be replaced.
    2. If the Print Cartridge light continues to blink even with pressure applied, the Access Cover sensor may be faulty and the printer will require repair.
