Stylus Pro5000
Table 3-16. Abnormal Phenomenon:
Color Gradation Differs Among the Printers
Step
1 If 2 or more Stylus Pro5000 are used in an office of by an
individual user, they may print the same data in different color
gradations. Generally, sine the printer is equipped with the
Auto Color Calibration, it only creates different color
graduations at an unnoticeable level. However, if the PC does
not support a Bi-directional parallel interface, it does not write
the adjusted value stored in the C228DRV board into the
driver. Therefore, it is required to register the adjusted value in
the driver forcibly by following the steps below.
2 Connect the printer with the PC with the cable and turn them
on.
3 Select "Utility" and next "Printer and Option Information (P)"
from the menu.
4 The windows for 'Printer ID" are ineffective. Select 'Setting
Sheet" so that the printer prints the adjusted values stored in
the EEPROM.
5 See the values output and input them to the 6 windows for
"Printer ID".
CAUTION Each of 2 printheads consists of 2 rows of head
nozzles for each color, and ink ejected differs in
weight from nozzle to nozzle. Therefore, Ink
ejected from each nozzle is weighed in the
manufacture and the data is stored in the driver as
the Printer ID. As a result, the printer manages to
equalize ink ejected from each nozzle in weight,
referring to the IDs.
