*In some print cycles a very small amount of surplus ink may be collected in the borderless printing ink pad. To
prevent ink leakage from the pad, the product is designed to stop borderless printing when the pad has reached its
limit. Whether and how
oen
this is required will vary according to the number of pages you print using the
borderless print option. e need for replacement of the pad does not mean that your printer has ceased to operate
in accordance with its
specications.

be performed by an authorised Epson Service provider. e Epson warranty does not cover the cost of this
replacement.
