Learn the safe, step-by-step process to replace ink cartridges on your Epson SC-P6070 printer, including tips for handling 700ml UltraChrome HDX cartridges like the T55J4 Yellow.

Quick answer

Replacing ink on the Epson SC-P6070 is straightforward: open the front cover, wait for the carriage to park, press the release tab on the empty cartridge, slide it out, then insert the new 700ml UltraChrome HDX cartridge until it clicks. Always update the printer firmware before using a new-series ink cartridge.

Why firmware matters before you start

Epson periodically releases firmware updates to ensure compatibility with newer ink formulations. The UltraChrome HDX ink used in the SC-P6070 includes improved Matte and Photo Black formulations, and the printer must recognise the cartridge chip correctly. Skipping the update can cause error messages or prevent the printer from recognising a fresh cartridge.

Before you begin the physical swap, check your printer's firmware version via the menu (Setup > Firmware Update). If an update is available, install it even if the printer is currently working — this avoids a mid-job interruption.

Handling 700ml cartridges safely

The 700ml cartridges used in the SC-P6070 are large and heavy compared to smaller consumer cartridges. When you remove an empty cartridge, hold it level to avoid ink dripping from the outlet port. The same applies when inserting a new one — tilt it gently into the slot and press firmly until the latch clicks.

Keep the orange protective cap from the new cartridge until you are ready to install it. If you set a cartridge down without the cap, the port can pick up dust or dry out, leading to clogged print heads.

Step-by-step ink replacement process

1. Prepare the printer: Turn on the printer and wait for it to finish any active job. Open the front cover. The carriage will move to the ink replacement position automatically. If it does not, select 'Ink Replacement' from the printer's menu. Common mistake: forcing the carriage manually. Let the printer park it — you can damage the mechanism if you push it.
2. Remove the empty cartridge: Press the release tab on the top of the cartridge that needs replacing. Tilt the cartridge slightly toward you and slide it straight out. Hold it level to avoid drips. Dispose of the old cartridge according to local e-waste rules. Checkpoint: note the colour label on the empty cartridge so you install the correct colour in the same slot.
3. Prepare the new cartridge: Remove the new 700ml UltraChrome HDX cartridge from its packaging. Keep the orange protective cap on until you are ready to insert it. Shake the cartridge gently side-to-side a few times to redistribute the pigment — this is especially important for cartridges that have been stored for a while. Common mistake: forgetting to shake the cartridge. Unshaken pigment can settle and cause uneven colour in your prints.
4. Insert the new cartridge: Remove the orange cap. Slide the cartridge into the correct slot at a slight angle, then press the top down firmly until you hear a click. The printer will automatically start charging the ink line — this takes about 2–3 minutes. Do not turn off the printer during this process. Checkpoint: if the click is not audible, the cartridge may not be fully seated. Remove and reinsert it until it locks.
5. Run a nozzle check: After the ink charge completes, close the front cover. From the printer menu, select Maintenance > Nozzle Check. Print the pattern and inspect it for gaps or missing lines. If the pattern is incomplete, run a head cleaning cycle and repeat the nozzle check. Common mistake: skipping the nozzle check. A partial clog after cartridge swap can waste paper and ink if you start printing directly.
