Thank you for your assistance in this matter. Everytime I replace the ink cartridge when the ink requires replacement the ink does not seem to inject. Sometimes I restart the system, that does not help. Sometimes I turn off my computer et al for a day, that does not help.
I put new cartridge in 2 days ago, still does not work. As the cartridges do not have instructions for this and the person who owns the hpdeskjet 940c printer is unable to locate the manual to alleviate this problem. HELP!!!

Try removing all ink cartridges and printhead from the printer. Then, look inside the printer with a flashlight. Look into the right side of the printer and see if there is lots of ink gunk. Remove if any and try not to leave ink gunk on other printer parts. Turn printer off when removing ink gunk. Then after you are done cleaning, turn printer on and wait for it to command you to insert printhead. Do that and close cover. Then, insert cartridges when printer asks for them. Hope that helps. -Alex 303Electronics eBay Stores
not-so-tech friendly, installing ink cartridges in printers can be
messy and time-consuming. Although companies such as Canon are
constantly trying to make designs more convenient for all users, there
are still several tips that can help new printer owners install Canon
PG-40 printer cartridges without mess or hassle.
Although many printer cartridges are specific to only a few models, the
Canon PG-40 printer cartridge was designed for use with many models of
the Canon Pixma and even some of the Canon fax machines. As of
September 2010, the Canon PG-40 ink cartridge can be used with the
Pixma iP1600 through iP1800 printers, the iP2600 printer, the MP140
through MP190 printers, the MP210 printer, the MP460 and 470 printers,
the MX300 and MX310 printers and the JX200 and JX210P fax machines.
This versatility allows users to stick with the same type of ink
cartridge over the life of several printers and allows small business offices an opportunity to buy one type of cartridge for all office printing requirements.
Replacing printer cartridges can be expensive and, if it is possible,
as it is with the Canon PG-40, refilling is a cheaper and more
environmentally friendly option. Refill the PG-40 by gathering a 10
cubic centimeter syringe with a 1.5-inch needle, a pair of latex free
gloves, an MIS Yellow Drill Tool, Scotch tape and black ink. Remove the
label from the top of the cartridge and use the yellow drill tool to
open the vent hole that was covered by the label. Next, load the
syringe with 20 CCs of black ink and inject it into the ink hole (where
ink leaves the cartridge for the page.) Make sure the needle reaches
the bottom of the ink tank and then slowly inject the ink into the
cartridge, stopping when the ink begins to well up at the needle
insertion point. Now remove the needle and clean the top of the
cartridge off to avoid color contamination. Put a small strip of Scotch
tape over the vent hole and poke a small hole in the tape with a pin.
Now reinsert the cartridge and run up to three cleaning cycles to
calibrate the printer.
Resetting the Ink Level
While refilling ink in a PG-40 can save money, it can also cause
difficulties when using the automatic ink level sensor. Reset this
sensor by removing the cartridge after the printer has been calibrated
and placing a thin strip of Scotch tape on the line of gold-colored
leads nearest the ink hole on the bottom of the ink cartridge. Replace
the cartridge and wait for the computer
to display a warning about the ink cartridge being loaded incorrectly.
Remove the cartridge and move the tape from the first to the second
level of leads and replace the cartridge. When the PC displays a
message that the cartridge is not recognized, remove the cartridge and
replace without the tape. The ink level will be reset.
1. Place the cartridge over somepaper towels in case there are any spills.Remove the label sticker from the topof the color cartridge.
2. Drill into the three small holeson the top of the cartridge to widen them so they will allow syringe needles.
3. Fill a syringe with 6 mL ofmagenta ink. Insert the needle into the refill hole that is located below thetwo protruding rectangles on the top of the cartridge. Slowly inject the ink.
4. Fill a syringe with 6 mL of cyanink. Insert the needle into the refill hole located below the large rectangleon the top of the cartridge. Slowly inject the ink into the cartridge.
5. Fill a syringe with 6 mL of yellowink. Insert the needle into the refill hole located below the small rectangleon the top of the cartridge. Slowly inject the ink into the ink chamber.
6. Replace the cartridge into theMX310 printer.
1. Set the cartridge on some paper towels.
2. Drill a hole into the dimplelocated directly above the semicircle on the top of the cartridge.Fill asyringe with 20 mL of black ink. Insert the needle into the hole and slowlyinject the ink.
3. Replace the cartridge into theCanon MX310.
switch the machine off then open the cover for ink cartrigde move the belt that the printer heads are on until in the middle replace cartridges and switch on machine this should work if the cartridges still does want to move the carriage rail could be very dirty and requires cleaning if you do not what you are doing advise you get a tech to assist you in this matter
If however it is a pc then maybe you should check your ink levels using the software that you installed with the printer.
Have you recently replaced the ink cartridges and if so did you use original HP cartridges ?
If you didn't use original cartridges then there is quite a good chance that they may be faulty and should be returned to where you purchased them for replacement.
If you did use original cartridges did you remove the tape on it before installing ?
Check by doing the cartridge replacement steps and take out any cartridge you may have replaced recently and check that the pull off tape tags are removed.
Ink has dried inside the printer.
Assuming the printhead is seperate from the cartridge, i would inject
JR Inkjet flush into the old cartridge and put it back into the
printer. Leave it to stand for an hour or two, then run several
Once the ink comes through (if it does) replace your new cartridge and clean again until the print quality is restored.
If this does not work. Then i expect a new printhead is required. (i would try the first suggestion repeatedly).
Ink cartridges should be replaced immediately if possible. and even if u need our technician support contact us at http://tinyurl.com/mtgjzz
Here's a permanent fix. Basically you cut the wire to the ink sensor. You can no longer see the ink levels, but that didn't matter anyway, as it was incorrect before! First of all, TURN OFF THE POWER TO YOUR PRINTER. Then lift up the scanner and remove the three screws along the top of the control panel. With a bit of force, snap-up the most inner two
Most likely the ink cartridges for this printer have a chip on them. This chip tells the printer how much ink is left and when it is low or out, you must replace the whole cartridge otherwise if you just refill it, the chip will still report the same amount of ink as it doesn't go by the actual ink level inside the cartridge, it determines the ink level by calculating approximately how much ink has been used while it was printing. So it doesn't matter how full the cartridge is, unless you replace the cartridge or reset the counter on the chip somehow, it will still display the calculated amount not the actual amount.
