Chip Unit Replacement and Ink Refills
Time Period for Chip Unit Replacements and Ink Refills
If the message
Chip unit expended
is displayed on the control panel, this means that the
chip unit needs to be replaced soon. Obtain an ink pack of the appropriate color as soon
as possible.
You will be unable to print if the chip unit for even one color needs to be replaced. If the
Chip unit expended
message is displayed during a print job, you can replace the chip unit
and refill the ink while printing continues.
For information on compatible ink packs, see “Options and Consumable Products” on
page 162.
Be sure to read the Safety Data Sheet before a replacement procedure. You can download
it at your local Epson website.
Important:
This printer has a remaining ink warning system. Use the following procedure for replacement
and ink refills to replace the chip unit and refill the ink correctly.
After the service engineer attaches the ink tank, replace the chip unit and refill the ink when
remaining ink is about 70 mm (2.8 inches) from the bottom of the ink tank.
This system does not directly detect the amount of ink remaining in the ink tank. Instead, the
amount of ink remaining is estimated based on the ink usage conditions and displayed as a
message. To maintain the accuracy of this system, you must replace the chip unit and refill the
ink as soon as possible once the remaining ink is 70 mm (2.8 inches) or less from the bottom of
the ink tank.
