Printer says incompatible cartridge

Unplug the printer for 5 minutes and then try again.

I have an HP officejet 4500. When I replace cartridge the printer reported Incompatible print cartridge. How can I get the printer to accept the cartridge and start printing again? The color cartridge is original to the printer and the black cartridge is the "new" one.

Most Laserjet Printers have "chips" mounted on the toner cartridge. This small circuit board can fail causing your error. If replacing your toner cartridge with an OEM HP Cartridge fixes it, then you know that was the problem. If the error persists after replacing the cartridge or swapping it from another printer with a known good cartridge then you'll need to call a tech

What is a incompatible print cartridge? The printer "Thinks" that the print cartridge, is NOT an original HP PhotoSmart one. Even print cartridge have chips.

Usually if you leave the printer off for sometime the ink get dry on the heads or some ink may leake to the sensores so take the cartrage out clean it and clean the heads with cotton swaps...see if the help and let me know

Hi,
Could be a bad cartridge too also.
Remove and reseat the cartridge, (power on)

On the front panel, press the Menu or Setup button (depending on the model).

Press the right arrow button (>) until Maintenance or Tools is displayed, and then press the OK or Enter button (depending on the model).

The Clean Print Cartridges message should display on the front panel.

Press Enter or OK to begin the cartridge cleaning process.

Clean the contacts on the device and cartridges

Using a cotton swab or lint free cloth with distilled or bottled water, clean the electrical contacts of the cartridge

Failing these, replace the cartridge.

Hope this helps
Regards

i had the same problem with the hp 4580. i needed to replace the black ink which i did. then the error message appeared "incompatible print cartridge tri color"...chatted with hp customer support, wasted a hour. claimed its a hardware problem need to have it fixed. i asked would i be charge he said yes but the printer was under warranty. he asked other questions...bottom line i left the chat box....bought another hp 4580, used same cartridges, same message...THEN finally i replaced the color cartridge...and BAM! it worked on both printers. solution...replace the color cartridge...cons..if this happens again its a waste of money to keep buying the colored ink...

refix your cartidge .may be your cartridge is faulty.

These types of severe cartridge errors (i.e. "refer to documentation" / "incompatible cartridges", "print cartridge(s) problem", etc.) typically indicates the internal micro-electronics of the HP #74 / 75 (or 74XL/75XL) cartridge(s) are damaged. The cartridge's electrical wire runs at rear and lower side of the ink cartridge, are very delicate and are somewhat susceptible to ink attack over time, which can lead to premature failures. In addition, the older the cartridge the higher the chance of an internal electrical failure. I suggest you first run a 'Tap 41' diagnostic test to check cartridges electrical health (this is a forced test); you may also bypass the error (temporarily) on most models which use HP 74/75 cartridges.

Pleas be certain to remove the clear tape from the cartridge before inserting. Check the contact areas in the printer to ensure there is no tape residue or other material in this area. Go to the HP website and follow the troubleshooting instructions for this problem.
