6.1.2 Service Maintenance
If any abnormal print (dot missing, white line, etc.) has occurred or the printer indicates
the "Maintenance request error", take the following actions to clear the error.
(This error is displayed in EPSON Status Monitor 3 and with LED.)
6.1.2.1 Print Head cleaning
When dot missing or banding appears on images, run the Print Head cleaning cycle.*
The cleaning be activated from the control panel, the printer driver utility or the
Adjustment program.
Note * : This printer has three manual cleaning modes. The appropriate cleaning mode is
automatically selected and performed according to various conditions. The ink
consumption amount for manual cleaning varies depending on the mode.
6.1.2.2 Maintenance request error
Ink is consumed also for cleaning and flashing operations. When the ink is used for
cleaning and flashing operations, the ink is drained to the Waste Ink Pads via the
Pump. The amount of the waste ink is stored as the waste ink counter into the
EEPROM. When the waste ink counter has reached the limit of the absorbing
capability of the Waste Ink Pads, the maintenance request error is displayed. This
printer takes the ink evaporation amount into consideration, therefore the counter limit
differs depending on how often printing is made.
For display of Maintenance request error, see the following.

Chapter3 "Troubleshooting" (p.29)
When the maintenance request error appears, replace the Waste ink pads with a new
one and reset the waste ink counter using the Adjustment program. If the waste ink
counter is close to its limit, recommend that the Waste ink pads will be replaced with
new one. This is because the "Maintenance request error" will may occur after
returning the repaired product to the customer.
