No Ink-Cartridge; Maintenance Request; Fatal Errors - Epson Stylus Photo Service Manual

Chapter 1 Product Description

1.5.4 No Ink-Cartridge

Following reasons can be the causes when printer goes to this error mode.
1) When the printer is turned on for the first time.
(This is a normal error state and it returns to the normal state after installing an ink cartridge according
to the ink cartridge exchange operation.)
2) Ink cartridge exchange operation is not done correctly.
After the position of carriage is moved by exchange operation, if the cleaning button is pushed without
installing ink cartridge or if the carriage returns to the home-position automatically without doing any
operation, it is considered as handling mistake. However, it returns to normal state by performing
ink exchange operation again and installing cartridge correctly.
3) If "No ink-cartridge error" appears even after the ink cartridge is installed, the printer must be
something wrong and around the sensor area in the carriage need to be repaired.
4) If sometimes printer can print normally but also sometimes "No ink-cartridge error" appears, the
printer must be something wrong. (Same reason as 3) above)

1.5.5 Maintenance Request

When the total quantity of ink wasted through the cleanings and flushing reaches to the limit, printer
indicates this error and stops. The absorber in the printer enclosure is needed to be replaced with new
one by a service person. The ink quantity that is absorbed by the absorber (waste ink pad) is monitored by
the software counter as "total ink counter". This counter is added by point system and also absorber's
maximum ability is set at the following reference value.

1-point = 0.0113ml (the value which is multiplied evaporating rate and 1-dot ink weight 0.02ml)

37000 = Maximum point number (Maintenance error threshold)
However, considering dispersion of ink absorbing quantity and the number of using nozzles, ink total value
is calculated by the following formula.
418 X 1.1/ 67% = 526 ml (but up to 687ml can be retained)
When you perform self test after completing repairs, it is possible to check the present value of total
ink counter conditions of all nozzles by performing status printing in the built-in function. Therefore,
make sure that the printer has enough value of total ink counter (if the number is close to 29500 or
not). If there is not enough value, the service man is required to judge if it is necessary to clear
EEPROM after replacing the absorber (waste ink pad) or not. Refer to section 1.4.2 if you need to
perform EEPROM Clear.

1.5.6 Fatal Errors
