Using pg8k ink only

It's mean "ink out". Not actually "inK", but ink level counter reached zero. If using original ink tank, just replace with new one. If using "hardware resetter", reset ink level counter. If using CIS ink tank, it will be auto reset.
Remember, it's program not actual ink. So, if you reset it, ink level will show full, even if you didn't refill ink tank.

This error occurs when printer fails detecting ink level or printer assume that no ink in the cartridge. We cannot use print, copy,scan, and fax function before the problem fixed. It's recommended for you to replace ink cartridge. To continue using the printer without replacing the cartridge we must deactivate ink level detection function. Be aware that printing in this condition can damage the printer while sending fax or scan is not problem.

Are you using the correct model ink, the error is pointing to your ink loader.
Make sure its using 8560 ink, using 8400 ink will cause this message. If you are using the correct ink then you have an issue with your ink loader, you can try taking the loader out and cleaning.

Hope this helps

The ink pad may be filled with ink.

• When you open the lid the ink cartridge cradle should slide all the way to theright of the printer.

• Unplug the power from printer then gently slide the ink cartridge cradle to theleft.
  
• Beneath the ink cartridge cradle's original resting spot you should see asmall ink pad about 1cm in .
  
• Using tweezers you should be able to removethis ink pad.

• Place the ink pad between two towels and squeeze until all the ink is removedfrom the pad.

• Using a Q-tip gently clean any ink buildup from where ink pad resides within theprinter.

• Remove the ink cartridges from the cradle and clean the print heads using adamp cotton ball.

• Put everything back into the printer and let it set for a few minutes beforeturning it on.

• Once the printer is on try printing.

Hi there
The onlty thing I can find close to this is.
Acording to the manual its a ink loader error like your loading the wrong type of ink like the puzzles pieces arent matching and hitting the sensor flags right. Yours by the 8 is referring to the black ink. Anyway go to troubleshooting on the control panel. then to service tools. when in service tools press and hold the up arrow while still pressing the up arrow press the down arrow. the display should say hidden menus. go to diagnostic mode press enter go to funtion menu. then go to clear ISC fault and enter. ISC=ink stick count fault. I hope that helps. Just to let you know Ive had nothing but problems with third party ink and once its in the system its hard to get out so I would watch what im doing with my expensive equipment

Using refilled in cartridges and incompatible inks result in the following problems.

• Refilled ink cartridges might leak and cause product damage. One method for refilling ink cartridges is to drill a hole through the cartridge, refill the ink, and then plug it. In some cases this plug does not hold, and the ink runs into the product and damages the printed circuit boards.
• Refilled ink cartridges frequently exhibit spotty printing or fail to print. This problem might be a direct result of the nozzles being plugged with dried ink. Because the vents of the refilled cartridges have been opened, air is able to enter the cartridge and dry the ink.
• Refilled ink cartridges might exhibit lower print quality, for the following reasons.
  • Printing algorithms used to create the various colors are based on particular printer inks. Using incompatible inks might result in color matching problems.
  • Refilled cartridges might have damaged nozzle orifices, result in various problems with print quality.
  • company products to which the printer belongs to can use a time delay between pages to accommodate the properties of the specific media type and ink being used. This prevents smearing problems from one page to the next. Using incompatible ink will alter the effects of this time delay and might result in poor print quality.
• printer might not recognize refilled ink cartridges. The refilling process may involve altering the ink cartridge enough that the product is unable to recognize it. The condition of the print cartridge electrical contacts deteriorates with use. This also results in the product being unable to recognize the refilled cartridge.
• Refilled ink cartridges might get stuck in the product. Because the cartridges from other manufacturers have been altered, cartridges might become stuck in the product. This problem might require that the product be disassembled to remove the cartridge.
• printer at times cannot predict the long-term effects on product reliability from using different ink formulations.

try this.
please rate my solution.
have a nice day.

Problem with ink flow. Use original ink or compatible? If original, ink will out and dried after head cleaning many times. If compatible, problem is ink quality. When head cleaning, ink flow to head by suction of head cleaning mech. If use to print, ink at head spray out, but ink ank ink tank not flowing good to head.

The ink your purchased is likely a cheap watered down version of what your printer is meant to take. You may notice that the ink smears when you rub the page directly after printing. Why you chose to use the blue and red ink to make black blows my mind. These refill kits are insanely cheap and buying the black could not have been much more. Not using black ink in the black cartridge would explain why your print is faded. Also, there is no way to reset the ink levels on this type of cartridge. As long as the printer still prints, just ignore the ink level indicator and print until the ink runs dry. I recommend Cartridge World for ink refills because they use high quality ink to manufacturer specified volumes while still saving you money.

HI~ First Check your ink..if you using compitetor ink or CISS ink , Remove The Rubber that are in the Ink Cattridge there, Coz When the print head **** the ink from catrige with pressure it will stuck the print head from spraying the ink out...  After Remove those rubber that are on the ink catrige you need to clean it to release those presure that build coz of those ink catrige build....                                                   If it dont work your print head need to be purge and you need to get in Maintenance mode...then coz you are using generic ink it maybe have spray to other part of the printer the ink Sensor is very close to ink absorber and the Generic ink usualy leak coz the design are not good but it is cheap and you need to know how to use it...

The 8BK is for printing photo's and high detail, it is usually only selected when you select to print high res / photo.
