5.1.2.2 Maintenance Request

When the ink is used for the Print Head cleaning and such, it is drained via the Cap
Unit to the Waste Ink Pad located on the Lower Housing. As for the ink absorbed by
the Front Paper Guide Pad when carrying out the borderless printing or flushing
operations, it is drained to the Front Paper Guide Pad. The amount of the waste ink is
controlled with the Protection Counter A (Waste Ink Pad) and B (Front Paper Guide
Pad) in the EEPROM on the Main Board. When the amount reaches the specified
value; which indicates that the waste ink has reached the limit of the absorbing
capability of the Waste Ink Pads, the "maintenance request error" is displayed.
 Timing for Replacing the Waste Ink Pads
 When the Protection Counter has reached the limit and the "maintenance
request error" is displayed
 When servicing the printer, always check the Protection Counter using the
Adjustment Program regardless of whether the Maintenance Request error has
been indicated or not. If the counter is close to its upper limit, replace the
Waste Ink Pads and reset the counter to "0" with receiving prior approval
from the user. This prevents the printer from causing the Maintenance
Request error soon after it is returned to the user.
