Maintaining and Transporting the Printer 169

Replacing the Maintenance Tank

The maintenance tank stores ink that gets flushed from the system during the initial ink charge and manual and automatic print head cleaning. When the tank is almost full, the message MAINTENANCE TANK NEARLY FULL appears on the LCD display. When the tank is completely full, the printer stops working and MAINTENANCE TANK FULL appears on the LCD.

You can check how much space remains in the maintenance tank by viewing its icon on the control panel, shown below. You can also check its status using the menus (see page 152), using your printer software (see page 153), or by printing a nozzle check sheet (see page 156).

Maintenance tank icons (only one tank icon appears on the

Pro 7900 LCD display)

The icon(s) show the approximate amount of space remaining in the tank(s).

The Epson Stylus Pro 7900 has one maintenance tank (on the right side), and the Pro 9900 has two (one on either side). Replacement tanks are available from Epson (part number C12C890191). See page 12 for details.

The printer will not print if one of the maintenance tanks is full. On the Epson Stylus Pro 9900, the right tank is used more than the left. To maximize tank life, you can switch the tanks when the right tank reaches approximately 40% to 60% of capacity.

Follow these steps to replace the tank:

1.If you have the Epson Stylus Pro 9900, check the LCD display to determine which tank needs to be replaced (left or right).

2.Turn off the printer.
