2.1.1.1 Printing Mechanism
Printing method for Stylus Pro5000 uses EPSON original’s MACH method,
like the previous models. Although 2 color heads which are the same ones
used for Stylus Color 800, are used for Stylus Pro500, auto color
calibration function is added to the heads used for Stylus Pro5000.
Therefore, since the ID contents written in the head is completely different
from the ones of Stylus Color 800,
the color heads of Stylus Color 800
can not be used for Stylus Pro5000 on the service.

CAUTION
„ „
Head shape of 2 heads mentioned above look
same. Therefore, when replacing 2 heads at the
same time, do not get confused which is right
head and which is left head.
„ „
It is possible to use the right head as left head,
but left head can not be used as right head. If
you ignore this, it gives bad influence directly
on the printing quality.
[Cleaning Operation]
Also, 2 printing heads are mounted on the carriage, but black head or color
head are not divided in this Stylus Pro5000.
Therefore, there is no cleaning function that clean the black head or color
head respectively. So, when the cleaning command is input from the
printer body or from the driver, these 2 heads are cleaned with the same
ink absorbing quantity.
[Nozzle Component]
Nozzle component is shown in the figure 2-1. It is one of the major
characteristics that black nozzles are included as a part of the color
nozzles. Also, 2 head are divided into either dark colors or light colors. In
the dark colors, there are black, Cyan, Magenta. In the light colors, there
are light cyan, light magenta, and yellow.
Each head: < (64 nozzles / Color x 3 lines) x 2 heads = Total 384
