Maintenance Overview 165
6.1.2.2 Maintenance Request
Waste ink is discharged to Waste Ink Pads via the Cap Unit. The printer has counter
function that counts how much waste ink is held in the Waste Ink Pads and stores the
value in the EEPROM as "Protection Counter A" and "Protection Counter B" (home
and non-home side). When the counter reaches the predetermined upper limit, the
printer causes the Maintenance Request error to indicate that the Waste Ink Pads is
nearly saturated.
Protection Counters Upper Limit
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.
