Printer won't print, message says ''wrong cartridge'' I have the correct cartridges installed and it still will not print.

Hello.
You must replace the cartridge. Toner and cartridge are two diferente things...

Message signals that the right cartridge is not correctly recognized.
May have several causes:
1. Cartridge model is wrong (not a Lexmark color cartridge 33 or 35). In this case one must replace the cartridge with the printer.
2. You use the correct cartridge but it is not recognized correctly. Try to clean the contacts on the cartridge and the printer with a soft towel or cloth.
3. If after you have cleaned the contacts you received the same message means that the cartridge is defective and must replace it with a new one.

Please follow the steps to replace the toner cartridge on the attached link: http://support.ricoh.com/bb_v1oi/pub_e/oi_view/0001037/0001037078/view/hardware/unv/0084.htm

If the message Replace Print Cartridge remains, it means that it is not the correct toner cartridge, replace it with the correct one. If Reset Print Cartridge message appears after correct replacement, it means that the toner cartridge is not set correctly or not installed. Set the toner cartridge correctly. If the cartridge is installed, close the front cover and turn the power switch to off and to on. If the message appears again, contact your sales or service representative.

Supported HP Inkjet cartridge part numbers The HP Officejet 4100 all-in-one series products use the ink cartridges listed in the table below. HP Inkjet cartridges HP 56 black cartridge (19 ml) HP 57 tri-color cartridge (17 ml) HP 28 tri-color cartridge (8 ml) Replacing the ink cartridgesThe power must be turned ON to the all-in-one or the print carriage will not move to the right.

1. Locate and open the print cartridge access door on the right side of the all-in-one. The print cartridge carriage will move to the right for access. Figure 1: Opening the HP Officejet 4100 series
2. Press down gently on the top of the old ink cartridge to release it from the print carriage. Figure 2: Removing an ink cartridge
3. Remove the new print cartridge from its packaging and remove the protective tape from the cartridge as shown in Figure 3. Do not touch the gold-colored contacts. Figure 3: Removing the cartridge tape
4. Holding the ink cartridge with the printed label up, slide the cartridges one at a time into the print carriage and press them into position as shown in Figure 4. If the cartridge does not snap easily into position, it is not aligned correctly. Remove the cartridge and reposition it. Do not try to force the cartridge into position. The black ink cartridge (HP #56) goes on the right side and the color cartridge (HP #57 or HP #28) goes on the left side. Close the ink cartridge access door when the ink cartridge has been installed. Figure 4: Installing the ink cartridges
5. A message will appear on the front panel requesting that the ink cartridges be aligned. Follow the steps below to align the ink cartridges:
   1. Press Enter on the all-in-one front panel to start the ink cartridge alignment process.
   2. After the Alignment page prints, place the page into the ADF upside down and with the printed side down as is shown in Figure 5.
   3. Press Enter. The all-in-one will scan the alignment page and finish aligning the cartridges.

Correcting error messages that appear after changing a cartridgeAfter inserting the cartridge, the Check Print Cartridge light flashes or one of the following messages appears on the computer monitor:

• Check the black (or color) cartridge
• Replace the black (or color) cartridge
• The wrong black (or color) cartridge is installed

These messages indicate that the ink cartridge is not making good electrical contact, is bad, or is the wrong cartridge. Complete the following steps to diagnose and correct the condition:

1. Open the front of the unit to access the print cartridges (as shown in Figure 1).
2. Remove the ink cartridge and inspect it.
3. Verify that it is the correct part number and if it is, reinsert it.
4. Close the lid to see if the problem is corrected.
5. If the message is still displayed after a few seconds, remove the ink cartridge again.
6. Unplug the power cord from the back of the unit.
7. Clean the electrical contacts on the ink cartridge with a soft clean cloth slightly dampened (not wet) with clean water. (See Figure 6) Each contact is very small and shaped like a rounded square. Figure 6: Cleaning the cartridge contacts
8. Allow the ink cartridge to dry for a few minutes before reinserting the cartridge(s) and turning on the printer.
9. If the problem remains, replace the ink cartridge.
10. If the problem still exists after trying all of the steps above, the unit may need to be serviced. Contact HP for further troubleshooting or to arrange to have the unit serviced.

Make sure what ur using isn't a refilled cartridge and if it is check the expiration date, if nothing is wrong then you need to get urself a new printer or an upgrade so call up hp at 1800-474-6836 and get help of them,they'll guide you to a new /upgrade printer.
it's not a nice way of saying it but someone has to give you the bad news

make sure all in correct. Clean sensors and cartridges then delete and reload driver. if this does not correct issue, then you have a faulty cartridge

Make sure you removed all the shipping tape from the bottom of the cartridges and that you installed the cartridges in the correct bays.

It appears that the problem is not in the ink cartridges at all but rather the print head assembly. Upon disassembly of the print head it can be discovered that the thing appearing to be a logic chip, is probably responsible for several standard commands including cartridge status. One should replace the printhead and then followed the instructions on aligning the printhead. This solves the problem. It can be  bought from Canon for about $45.00 including shipping. Hopes this helps. Thank you, Have a nice day...!

HP Color LaserJet 2600n Printer - Installing Print Cartridges When a print cartridge approaches the end of useful life, the control panel displays a message recommending that to order a replacement. The printer can continue to print using the current print cartridge until the control panel displays a message instructing to replace the cartridge. The printer uses four colors and has a different print cartridge for each color: black (K), cyan (C), magenta (M), and yellow (Y). Replace a print cartridge when the printer control panel displays one of the following messages: Replace yellow cartridge, Replace magenta cartridge, Replace cyan cartridge, Replace black cartridge. The control panel display also indicates the color that should be replaced (unless a genuine HP cartridge is not currently installed). Change the print cartridge

1. Turn off the printer.
2. Open the front door. CAUTION: Do not place anything on the transfer belt (ETB), which is located on the inside of the front door.
3. Remove the used print cartridge from the printer.
4. Remove the new print cartridge from the bag. Place the used print cartridge in the bag for recycling.
5. Grasp both sides of the print cartridge by the blue handles and distribute the toner by gently rocking the print cartridge from front to back. CAUTION: Do not touch the shutter or the surface of the roller.
6. Remove the orange shipping locks and the orange shipping tape from the new print cartridge. Discard the shipping tape and shipping locks according to local regulations.
