Troubleshooting Tip:
Cartridge is leaking:
Some of our cartridges may have been overfilled by thefactory. We suggest you open the cartridges at a sink or over your garbage canto avoid possible leaks from damaging your valuable items.
The internal pressure in the vacuum is not balanced. Thecartridge should work fine anyway. Let the cartridge sit (print head down) on apaper towel for a few minutes, then clean it up and install. (For a hightemperature area) When the cartridge is opened, the ink may bebubbling/dripping out of the cartridge if it has been in a high temperatureenvironment for a long time. This is because the heat creates pressure withinthe sealed cartridge and that pressure blows the ink out when the cartridge isopened. Please try chilling the cartridge in the refrigerator (not freezer) fora couple hours before use.
Cartridge has adifferent shape:
The shape of our compatible cartridges may look a littledifferent from OEM cartridges, but they are designed for use in your printer,and will fit.
My cartridge won\'tfit:
Please make sure to remove the plastic protective case fromthe cartridge.
Low ink messageshowing at the printer:
All of our cartridges are fully filled with ink. However,there are a small number of our cartridges that may not have been reset fullyduring the re-manufacturing process. Either bypass the low ink message ordisable the ink level system on your printer. Although your printer will nottrack the ink levels, our cartridges will print fine from start to finish. Oncertain Epson and Lexmark printers, if the printer is saying you cannot printdue to low ink, please press and hold the \"stop\" or\"cancel\" button for 10 seconds. This will reset the counter and allowyou to use the cartridges normally.
The print quality isnot very good or the printout contains no ink
Make sure that youhave removed the foil or plastic strip covering the vent hole and the nozzle.(Usually a bright color, but sometimes clear.)
Make sure that the vent hole at the top of the cartridge andthe nozzle are unblocked by any tape or plastic strip.
To ensure that the vent hole is unobstructed, use a paperclip or another small, pointed object to probe the vent for blockages.
