There are not many wipers remaining. Immediately stock up on wipers. Leaving the printer in a state in which it does not have a wiper will lead to head damage.

This message appears when the amount of wiper remaining is low and is close to zero.

Replace the wiper. Leaving the printer in a state in which the print heads cannot be wiped for a long time will lead to head damage. If you do not have a replacement wiper, order one. Then, carry out the replacement as soon as the wiper arrives.
