ERROR CONDITION
Stylus Pro5000 goes to error condition when it falls to the following
conditions. Out of Centronics interface signals, BUSY signal is set High and
/ERROR signal is set LOW. Then, the printer goes to unprintable state,
stopping data input from outside. Once the error happens, the printer can go
back to the standby position or ready status for printing again by removing
the error causes.

Ink near end and Ink out Error
When the printer runs out the most part of the ink of any one color, it
warns ink-low and keeps printing. When the printer runs out the whole
ink of any one color, it stops printing and indicates ink-out error. User is
requested to install a new ink-cartridge in this state.
A ink-cartridge once taken out should never be used again. Re-
installation of the cartridge not filled fully upsets the ink level detection
and may cause a serious problem in the print head as a result.
CAUTION
Although there is no worry of bubble invasion by
pulling out or installing the ink cartridge, it is
necessary to pay attention to the following points.
1)If the ink cartridge is once removed and installed
again in the condition that the ink out(end) sensor
detects the ink is still in, ink consumption based
on the previous ink life will be kept counting.
2)If the ink cartridge is once removed and the ink
cartridge whose left ink quantity is little is installed
again in the condition that the ink is still in, Stylus
Pro5000 goes to the ink out error condition, even
though there is still enough ink in it.
‰
Paper out sensor
When there is no paper in the paper tray, or paper tray itself is not
installed, this sensor detects and goes paper out error.
‰
Paper loading miss:
When printer fails to load a sheet or PE sensor does not detect the
paper on the path, it goes paper out error.
‰
Paper Jam Error
Even when the paper feeding is performed at the power on, if the PE
sensor detects the paper on the paper path or fails to eject a paper by
FF command or Eject button, the printer considers it as paper jam and
goes to the error condition. In the Stylus Pro5000, the linear encoder
monitors detection of paper jam in the carriage running range.
‰
No ink-cartridge
When the printer detects that ink cartridge comes off or is not installed, it
goes to the error condition.
‰
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(waste ink pad) in the printer enclosure is needed to be
replaced with new one by a service person. This error does not recover
until the waste ink pad is replaced and “0” is written to the particular
address in the EEPRON by a service man.
‰
Fatal Errors
When fatal errors such as carriage control error or CG access error are
detected, the printer goes to error condition and stops. Repair service is
required for this error.
