4.2.4.4 Upgrade Service Preliminary Check Items
o It should be confirmed whether CPS Ripper Pro and Postscript Server are installed
in the system environment that uses the Stylus Pro 7000. If this service is
performed for users which are using the Stylus Pro 7000 under these
environments, the following system disks and materials should be brought
together with this kit when the service is performed.
n Users who are using Postscript Server PS6100.
• PS6300 System Software CD-ROM
• Boot ROM program
• SCSI CD-ROM drive
n Users using CPS Soft Ripper PRO
• Soft Ripper PRO software package.
o The results of the nozzle check of the Stylus Pro 7000 currently in use by the user
should be checked. If skipping of dots is occurring, carry out head cleaning 3 times
and if it still doesn’t recover, use a light system head, regardless of whether the
head causing the dot skipping is a dark system head or a light system head (ASP
Code: F055050), and this should be brought together with this kit and the other
materials when the service is performed.
The purpose of preparing a light system head is that its printing precision is higher
compared to that of the dark system head and it is effective in solving the problem
of banding when users report banding problems, and prevents it from recurring,
thus eliminating customer claims in this area.
o If the customer purchases MC mat synthetic paper or MC mat synthetic paper
(with adhesive) when this service is contracted for, depending on the conditions, it
is recommended that the optional 2-inch high tension spindle be used together
with it.
This paper is structurally weak and has a tendency to deflect more than necessary
between the spindle and PF roller during paper feed, so if 4 m or greater lengths of
paper are printed on, there is a possibility that wrinkles could occur at the PF
roller. Therefore, the optional 2-inch high tension spindle, with its high back
tension, is effective when used together with this paper.
o If the customer purchases MC Image paper when this service is contracted for,
depending on the conditions, it is recommended that the optional 3-inch high
tension spindle be used together with it.
This paper is structurally extremely weak and has a tendency to deflect by
becoming unwound between the spindle and PF roller during paper feed.
Therefore, the optional 2-inch high tension spindle, with its high back tension, is
effective when used together with this paper.
