FX Series 7 Printing Support

The FX Series 7 ink cartridge uses inkjet technology and contains two print heads that must be aligned. The nozzles need regular cleaning for good print quality — the machine cleans them automatically or on request, and you can also clean them manually.

How do I deep-clean the FX Series 7 ink cartridge?

If the cartridge will not print despite having ink (no print, half print or poor print), deep-clean the print head with hot water until the ink flows in two parallel tram lines.

You will need: the faulty ink cartridge, a folded warm damp cloth, folded tissue or kitchen roll, and a mug of boiling hot water.

1. Remove the ink cartridge from the franking machine.
2. Press the cartridge down onto folded tissue to see if the ink flows.
3. Place the tip of the print head into the boiling water and hold it there for around 30 seconds.
4. Press the cartridge onto a warm damp cloth for around 10 seconds.
5. Press it onto the tissue again to check the ink flow — you are aiming for two parallel tram lines.
6. Place the cartridge back in the machine and run a test print. Repeat if the problem persists.

How do I replace the ink cartridge on the FX Series 7?

To replace the ink cartridge, open the cover, click out the old cartridge and fit the new one, then let the machine align it.

1. Open the cover/lid — the cartridge moves to the replacement position.
2. Firmly press down on the bottom of the cartridge to disengage it; it clicks out of place.
3. Slowly and carefully lift out the old cartridge.
4. Remove the protective layer from the new cartridge.
5. Place the new cartridge into the machine so it is seated nicely, then firmly press down on the top until it clicks into place.
6. Close the cover/lid and press OK. The alignment process starts automatically.

Caution: Keep your fingers away from the cartridge while it is moving to the replacement position.

How do I fix printing problems on the FX Series 7?

The FX Series 7 cartridge is made from two offset HP45 cartridges, whose nozzles can clog with paper dust or dry out in transit, storage or after non-use. To fix poor print, clean and prime the print heads against tissue until two solid tram lines appear.

1. Remove the ink cartridge from the franking machine.
2. Clean the print heads with a warm damp cloth or tissue.
3. Hold the supplied alcohol wipe (or tissue) against the heads, point the brass print heads down and away from you, and shake well, keeping the tissue tight against the heads.
4. Check for two solid tram lines. If you see no ink or broken lines, wipe the heads and repeat.
5. If it persists, clean the brass print heads with a cloth and warm soapy water, then repeat.

Caution: Ink may leak during this process — handle the cartridge carefully and keep the tissue pressed against the print heads.

Good ink flow — two solid tram lines:

Poor ink flow — no ink or broken lines (repeat the cleaning):
