MAINTENANCE
Maintenance Request Error
Ink is used for operations such as Head Cleaning as well as printing. In that case,
the ink is drained into the Waste Ink Pad and its amount is counted in the Waste
Ink Counter set in the EEPROM on the control board. When the preset value is
reached (Waste Ink Counter = Waste Ink Pad Counter A = variable between 20000
and 46750), The Waste Ink Counter detects that the Waste Ink Pad has reached its
predetermined limit. The Maintenance Request Error will be displayed on Status
Monitor 3 as shown below.

If this occurs, replace the Waste Ink Pad and reset the Waste Ink Counter set in the
EEPROM. Resetting of the Waste Ink Counter can be done only from the
Adjustment Program since this product does not have the reset function for the
Waste Ink Counter through the operation Panel Switch. Refer to Chapter 3
"ADJUSTMENT" for the reset procedure. During repair service, the Waste Ink
Counter must be checked according to the firmware version, the Main Board
checker program version and the Nozzle Check Pattern of the Nozzle Check
Pattern Print. Because another "Maintenance Request Error" could occur after
returning the repaired product to the user, if the Waste Ink Counter is close to its
limit, it is recommended that the Waste Ink Pad be replaced.
