HP Business Inkjet 2800

There should be a small switch that depresses when the access latch is closed. Check the part that the latch presses on, it should move freely and be springy. Sometimes these actuators will pop out of place or completely off of the switch.

The error can be the result of firmware code, printer contacts or the printhead itself failing. There is a firmware update that addresses the "Printhead Error" on your printer. Please follow the steps below on how to successfully update your printer and provide information to the following questions:


1. Open the cover to remove the printhead and tanks (if installed). You may go to http://bit.ly/klw9sJ to have a visual on how to remove the printhead. Note: Carrier will come to the center automatically with this error message as the cover is opened.

Hi

Did you check the connections in the carriage if there is little amount of ink on the contacts? if not then clean it well with a dump cloth and try to re-install the old printhead it will sure accept it. If not then the other way is to change system date of the printer first and then try again.

DO RATE MY SOLUTION

It apparently thinks one of the plastic covers is open so I would check to see if the part on the doors that contacts the sensor is broken or damaged.

Hope this helps you. This error is caused by either a correct or incorrect detection of air in the manifold. The steps below will clear the error condition, which should solve the problem if it is caused by an incorrect detection of air. If there really is air in the manifold, however, this procedure will not solve the problem and the printer will have to be serviced. Step 1 - Remove all printheads CAUTION: Do not touch the printhead tower. Do not remove the printhead handle. Keep printheads out of the reach of children. Figure 1: HP 14 printhead 1 - Handle 2 - Tower

1. Make sure the unit is plugged in and the power is turned on.
2. Open the print carriage access door by lifting the handle until the door locks in place. The print carriage moves to the center.
3. Wait two or three seconds, then unplug the power cord.
4. Open the printhead latch. See the illustration below. Figure 2: Open the printhead latch
5. Remove each problem printhead by lifting the printhead handle and pulling up. See the illustration below. Figure 3: Remove the printhead

Step 2 - Reset the internal error state NOTE: This step must be performed before the printheads are re-installed.

1. Close the printhead chute.
2. Close the access door.
3. Plug the power cord back in.
4. Turn on the power. The front panel should read No Printhead. Will damage Product. Insert [color name] [icon] printhead now . NOTE: The carriage may make a grinding noise when you turn the power on. This noise is normal.
5. Open the print carriage access door by lifting the handle until the door locks in place. The print carriage moves to the center.
6. Wait two or three seconds, then unplug the power cord.
7. Open the printhead latch.

Before re-inserting the printheads, make sure all the electrical contacts have had at least five minutes to dry. Step 3 - Insert the printheads

1. Place each printhead in its slot in the printhead carriage. The colored shape on the top of the printhead should match the colored shape on the proper slot on the printhead carriage.
2. Press down firmly and evenly on both the front and back of the printhead, as shown in the illustration below. Proper seating is essential to making good electrical contact.

Figure 4: Seat the printhead Step 4 - Close and check the printer

1. Close the printhead carriage latch and make sure the loops catch the hooks. See the illustration below. Figure 5: Loops catch hooks
2. Snap the latch into place.
3. Plug in the power cord.
4. Close the print carriage access door.
5. Turn on the power.
6. If the error clears, a message to align the printheads may appear on the HP Officejet D and HP Officejet 7100. Press Enter to align. If the error persists contact HP. Printhead replacement will not resolve this problem - the printer will have to be serviced.

Printheads are very sensitive and HP sets a "Time" limit of about two years for # 11 printheads regardless of how much you print. ( This is bunk from HP of course!.) But the prinheads do not expire!! They just show their health and that the printhead has exceeded the warraty period ( regardless of how much you print) .

Remove the printheads from their socket and fill a 8- 12" dish with 1/4" high of warm water. Set the printheads in the water in the same position they are set in the printer (vertical) You may need to place a wooden spoon of a block behind the printheads to keep the heads in position, as they will tilt backwards.
Leave the printheads to soak for about 15minutes.
Remove the printheads and slightly press them on a folded kitchen paper towel .It should show two lines of the same color of the printhead (cyan, yellow, etc) If the two lines are not of the same length (about 1/2" long) then repeat the soaking for that color. Be sure to dry the printheads properly

Install the printheads in the printer socket vertically so the contacts are properly set.. If not you may get a message to "Install (color) printhead". reset it again and run at least 15 pages with color information. It should print ok!!
If any print heads is damaged then the only option is to replace it with a new one.
It may be that the ink line from the cartridge to the printhead is clogged and ink is not flowing. This may require to run a large print job of about 50 or so pages to force ink into the clean printheads.

The terminal strip behind the printhead that makes contact with the pins in the printer are very delicate and if removed two to three times may not make a good contact and render the printhead unuseable.

Good Luck!!

reset it in window printing menu. perhaps it works.

When you removed the paper it's possible your damaged it and that's why the message is not going away. Did you try to put the cartridge back in to make sure it had not come out of position and just remove the power cord for a minute then plugging it back it.

Here are the steps to make sure you properly change the cartridges and the heads...

Install the ink cartridges and printheads Step one: Install the ink cartridges All four ink cartridges must be correctly installed for the HP All-in-One to work. Follow the steps below to Install cartridges:

1. Open the ink cartridge cover.
2. Remove each ink cartridge from its package.
3. Align each ink cartridge with its color-coded slot and then insert the ink cartridge into the slot. To ensure proper contact, press down firmly on the cartridges until they snap into place.
4. Close the ink cartridge cover.

Figure 1: Installing cartridges 1 - Open the ink cartridge cover. 2 - Remove the ink cartridges from the packages. 3 - Install the ink cartridges. 4 - Close the ink cartridge cover. Step two: Install the printheads Follow the steps below to install the printheads.

1. Open the top cover of the printer. Figure 2: Open the top cover
2. If the carriage does not move to the left automatically, press and hold the Resume button ( ) for three seconds. Wait for the carriage to stop moving.
3. Remove the cardboard cover from the printhead carriage. Figure 3: Remove the cardboard cover
4. Lift the printhead latch. Figure 4: Lift the printhead latch
5. Before installing a printhead, shake the printhead up and down at least six times while the printhead is still in its packaging. Figure 5: Shake the printhead while it is still in its packaging
6. Remove the new printhead from its package, and then remove its orange protective caps. CAUTION: Do not shake printheads after the caps are removed. Figure 6: Remove the printhead from its packaging, then remove the orange caps from the printhead
7. Insert the printhead into its color-coded slot. The label on the printhead must match the label on the printhead latch. Press down firmly on the printhead to ensure proper contact. Figure 7: Insert the printheads in the correct color-coded slots
