1.5.4 No Ink-Cartridge
Following reasons can be the causes when printer goes 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 done correctly.
After the position of carriage is moved by exchange operation, if the cleaning switch 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 absorber’s maximum ability is set at
the following reference value.
✳
29500 X 0.0102 ml = Approximately 301 ml
1-point = 0.0102 ml (the value which is multiplied evaporating rate and 1-dot ink weight
0.02 ml)
29500 = 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.
✳
301 X 1.1
÷
63% = 526 ml (but up to 532ml can be retained)
WARNING
When you perform self- test after completing repairs, it is possible to check the present value of total
ink counter and ink discharge conditions from 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
When printer detects fatal errors such as carriage control error or CG access error, it goes to this
error mode. Refer to followings for each error.
1) Carriage control Error : Parallel adjustment malfunction, Home-position malfunction, Timing
belt tension malfunction, shortage of lubricant on the carriage guide shaft, etc.
2) CG Access Error
: Short circuit, etc.
