EPSON Stylus Photo 750
† No Ink Cartridge
When the printer detects that ink-cartridge comes off, it becomes
"No ink cartridge error" condition.
„ When you need to perform test print after the repair
service, performing the status-printing(see "Control
Panel" on page -21) provides the discharged ink
condition from the all ink nozzles and the current
value of the waste ink counter. Be sure to check
that the counter value still has enough capacity.(if
the value is closer to 2700 or not)
„ If there is no enough capacity, exchange the waste
ink absorber and find out if it is necessary to reset
EEPROM or not. If you need to reset EEPROM, refer
to "Special Setting Mode" on page -22.
† Maintenance request
When the total quantity of ink wasted with cleaning and flushing
reaches the limit, the printer indicates this error and stops printing.

one by a service person. The counter is added by points and its limit
is as follows.
„ 37000 point = Approx. 418ml

components or assessing the CG, it becomes "fatal error" condition.
