EPS-5034 • Epson 7900 and 9900 changing from stock Epson inks to dye ink

Topic:

How do I change from the stock Epson HDR black inks over to dye inks?

Resolve:

The new Epson printers such as the 7900 and 9900 are not as friendly as the older models when converting ink systems.

The older printer models used a single ink slot for both matte and photo black inks. When a user needed to change ink there was a control panel option and an ink conversion kit that helped flush only the single black ink line.

The new wide format printer models such as the 7900 and 9900 install both black matte and photo black inks using "the same print head for both inks" switching between the two inks on demand using a control panel option.

During the cross over ink is purged from the head and replaced with the next supply. The exact amount of ink wasted each time you convert is listed below (from the Epson user guide).

Generally, you should switch black ink cartridges only if you plan to run a
large number of print jobs in the new mode.
• Switching from Photo Black to Matte Black takes 2 minutes and
consumes approximately 1.2 ml of ink.
• Switching from Matte Black to Photo Black takes 3 minutes and
consumes approximately 3.4 ml of ink.

How do I switch one black ink over to a dye ink supply so I can make screen print films?

Epson has blocked that option with its new setup, no longer making it an easy thing to do.

1. You can add the new ink cartridge then print lots of black squares until the ink exchanges, but how do you know when it has, that is the trick. It's all guess work. Might take as many as 60 prints of a 5" x 5" square.

2. From the front control panel you can clean groups of heads. Find the color ink you want to clear and clean it until it exchanges the old ink for the new ink. Not as good as it was but this is one way to get it done.
