6.1.2.2 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 Tray Assy 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 ink pads in the Front Paper Guide Pad Tray. The
amount of the waste ink is controlled with the Protection Counter A (Waste Ink Tray
Assy) and B (Front Paper Guide Pad Tray) 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.
 Protection Counters Upper Limit

Protection Counter B
Note* : Taking the ink evaporation amount into consideration, the threshold
value of the Protection Counter A for the Maintenance Request varies
from 12,300 to 14,250 accordingly until 260 days pass from the day the
printer receives the first TI from the printer driver (the printer is initially
used). The value after 260 days is 14,250.
 Timing for Replacing the Waste Ink Pads
 When the Protection Counter reaches the value shown above, a Maintenance
Request is indicated.
 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 shown above,
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.
