While reseating a cartridge is not difficult but there are a number of errors that can occur if the user does not manage it properly. Reseating a cartridge should not be a difficult task for anyone with a passing knowledge of printers. The reseating error can occur after the user has replaced the black ink cartridge. It is a common problem with the black ink cartridge. The user may attempt to replace the cartridge number of times, clean the contacts and restart the plotter. If there is a problem with replacing the black ink cartridge that cleaning the contact does not fix, then it is best to simply replace the carriage assembly first. If this does not solve the problem then the user may want to consider replacing the trailing cable.

Hi there,

Caution : Do not touch the transparent film, film cable, ink absorber (sponge part) or any metal parts.

Important : * Do not reattach the Protective Tape once you have removed it,
* Handle the removed Protective Tape carefully to avoid getting your hands dirty or staining the surrounding work area once you have removed it.
* Once the Protective Tape is removed, do not touch the gold terminals of the FINE Cartridge or its nozzles. The machine may not print out properly if you touch the terminals.

* Replace the FINE Cartridge runs out of ink, replace the FINE Cartridge with a new one immediately. If you replace it with the FINE Cartridge that has previously been removed, the machine may not print properly due to clogged FINE Cartridge nozzles. Furthermore, the Low Ink Warning dialog box which advices when to exchange the FINE Cartridge will be inaccurate.
* To maintain optimal print quality, use up all the ink in the FINE Cartridge within six months of its first use. (We recommend that you note the date that the FINE Cartridge was installed in the machine.)
* Color ink consumption may occur even when black-and- white or gray-scale printing specified.
Color ink is consumed during Cartridge cleaning, which is necessary to maintain the machine's capabilities.

If ruled lines are misaligned or a printout is unsatisfactory, FINE Cartridge Alignment is required,

* Aligning the FINE Cartridge
1) Press [Maintainance] repeatedly until <P> appears.

2) Press [Black] or [Color].
The machine prints the head alignment sheet.

3) Beginning from Column A on the printout, enter checkmarks in the patterns that have the most solid image.

Note : If you select <L> in step 1, the machine prints the current FINE Cartridge Alignment setting.

Hope this helps.

your cartridge is not original you buy new one

If you need to replace an ink cartridge in your printer, please follow the instructions below:

To confirm which ink cartridge requires replacement, please use the printer's control panel (there is a black ink out indicator, as well as a color ink out indicator ), or the Status Monitor in your computer.

Red light flashing - Low ink
Red light solid - Out of ink

1. Open the printer cover and press the INK (Cleaning) button for 3 seconds. The print head moves to the center and the lights flash.
2. Lift up the ink cartridge clamp. The cartridge rises up from its holder.
3. Remove the cartridge and dispose of it carefully. If ink gets on your hands, wash them with soap and water. If ink gets in your eyes, flush them immediately with water.
4. Unpack the new ink cartridge and remove the yellow tape. You must remove the yellow tape from the top of the cartridge. Do not remove the clear seal underneath the cartridge. Do not touch the green circuit board on the back of the cartridge, or you may inhibit normal operation and printing.
5. Tilt the new cartridge toward you slightly as you insert it. Lower the cartridge so that the tabs rest on the hooks. Do not place the cartridge tabs under the hooks.
6. Press down firmly on the ink cartridge clamp until it snaps in place.
7. If you need to replace the other ink cartridge, repeat steps 2 through 6 before continuing with step 8 (to move printhead over to color (if black was replaced first) press the cleaning button once).
8. Press the INK (Cleaning) button once, and close the printer cover. The printer begins charging the ink delivery system.
9. Wait until ink charging is finished (the power light stops flashing and the red error light goes out).

My HP Deskjet 6940 is not printing. The color (left) low ink light is dark and the black (right) low ink light is flashing. I replaced the black ink cartridge with a new one but the low ink light continues to flash. No tears/rips in the circuit strip and all the copper leads appear to be connected
