The Printhead Cartridge
The Memjet printhead cartridge contains over 70,000 inkjet nozzles. These nozzles are divided into ten rows; two rows of nozzles for each color channel. Due to the very tiny size of each nozzle and the high number of nozzles; it is not uncommon for some nozzles to become contaminated or clogged.

Incompatible media. Table is not level. Printer was not powered-down properly. Printhead may not have been cleaned or capped. Ink system may not have been stabilized. | Refer to “Printhead Cartridge Conditioning”. If problem persists; refer to section titled “Color Mixing Issues”.

System will not prime the printhead after installing Printhead Cartridge (During the priming process one or more of the ink color tubes are not filling with ink.) | Printhead nozzles dry (air pulled through nozzles; not allowing system to create vacuum) Capping station not making good seal against the printhead. Pinched/kinked ink tube(s) Ink Tanks may not have enough ink in them to prime system.. Ink Tank Issue Toolbox displays …Low_Ink or Ink_Out… message. Toolbox displays Ink_Error Printhead ink channel(s) are clogged Toolbox displays Ink Valve Error. Damaged Ink Coupling (revolver) | Wet the Printhead nozzles using distilled water and a wet, lint-free cloth. Check for obstruction. Is the Head Media Guide in the way? Try removing it. Check ink tubes. Is the Antistatic Brush Assy pinching tubes? Replace Ink Tank(s). Replace the Printhead. Contact Service Support. |
Ink leaking from the printhead nozzles | Print Engine was opened to angle greater than 60º. Table is not level. Excessive back-pressure within ink system; caused by print engine being powered-down when not in use. Wicking material, inside capping station, is making contact with the printhead nozzles. Opening in ink system; allowing loss of vacuum. | Do NOT open Print Engine to angle greater than 60º. Manually clean printhead. Make sure table, that printer is placed on, is sturdy and level. Allow print engine to remain powered-up, when not in use, so it can routinely cycle the pinch valve to equalize back-pressure in the system. Replace the capping station or the entire service station. Install missing Ink Tanks. Verify that Ink Tank Latches are fully closed and locked. Clean Ink Couplings. Verify that Printhead Latch is fully closed and locked. Contact Service Support. |
