Roland SolJet Pro II V SC-545EXW User manual

1
This manual describes important information that you should know before you use
the SC-545EXW (white-ink model).
Features
➢This machine is a large-format printer capable of printing white
ink in addition to four-color (CMYK) inks. This makes it pos-
sible to achieve unique expressiveness not possible with con-
ventional printers, such as by printing CMYK colors on white.
➢This machine employs proven ECO-SOL inks.
➢This machine cannot use light cyan or light magenta inks.
About the User's Manuals for This Machine
➢Read this manual along with the SC-545EX User's Manual.
The present manual describes the differences between this
machine and the SC-545EX (six-color ink model).
➢Read this manual first to gain an understanding of the
machine's characteristics and important cautions. For other
matters, refer to the SC-545EX User's Manual.
Be Sure to Read This First
Important: Characteristics of White Ink
The usage and handling of white ink involves some important considerations that do not apply to ink of other colors. Be
sure to familiarize yourself with the characteristics of white ink before you use it.
White ink settles and separates.
➢If it is allowed to stand, the precipitated material may so-
lidify and cause clogging of the print heads or other mal-
function. Be sure to observe the cautions in this manual.
Periodic maintenance is necessary and must be per-
formed without fail.
➢We recommend operating the printer at least once a week.
➢Maintenance must be performed at least once every two
weeks, even when the machine is not in use.Allowing it to
stand may result in malfunction.
➢Maintenance requires four SOL INK cleaning cartridges, so
be sure to have these on hand.
Be sure to shake the cartridges before each use.
➢Before every printing operation, be sure to remove the white
ink cartridges and shake them gently. Failing to do this may
result in faint color or cause breakdown.
Drying white ink
➢Allow all ink (not just white ink) to dry sufficiently. Note
that white ink in particular requires printing at a high den-
sity, and so is more difficult to dry than CMYK inks.
➢We strongly recommend using a media dryer.
Using white ink out of doors
➢Depending on conditions, the weatherability of white ink
may be inferior to that of CMYK inks.The ink may deterio-
rate and become powdery, peel or flake off, or smudge.We
recommend performing lamination when the white ink is
to be used out of doors.

Installing the Ink Cartridges
The procedures for installing ink cartridges for the first time (ink
filling) and for replacing cartridges are basically the same as for
the SC-545EX (six-color ink model). Note, however, that the fol-
lowing points differ.
➢When filling ink, make sure the ink type is set to "ECO-SOL
KCMYWW."
➢Install two cartridges each for cyan, magenta, yellow, and
black, and four cartridges for white. Shake each cartridge gen-
tly before you install it.
➢Never insert a light cyan or light magenta cartridge.
➢The [INK REMAINING] menu does not correctly display the
amount of ink remaining in the white ink cartridges.

ActionsThat Must be Performed Continuously
What to Do Before Starting Every Printing Operation
➢Before switching on the power, remove the white ink cartridges,
shake them gently, then reinsert them.
➢Be sure to carry out this operation every time before you start
printing.
➢CMYK ink cartridges do not need to be shaken before every
operation, but be sure to shake them when installing new ones.
If a message appears
➢If this message appears when you switch on the power, be
sure to carry out maintenance.
☞Refer to page 3, "Maintenance Operations."
Periodically switch on the power.
➢At least once every two weeks, be sure to switch on the power
and perform maintenance as instructed by the messages dis-
played.
➢We recommend performing printing at intervals no longer than
one week.
☞Refer to page 3, "Maintenance Operations."

Message displayed: [INK RENEWAL FULL]
➢Insert and remove only the white ink cartridges.
➢"Full" maintenance requires four SOL INK cleaning cartridges.
➢Four cleaning cartridges can be used to perform maintenance
five times. Never use them more times than that. Doing so
may damage the machine.
➢This message appears when two weeks or longer have passed
since the last time "full" maintenance was performed. If the
printer has been out of use, however, it appears after one week.
➢Pressing the [MENU] key makes the message disappear with-
out performing maintenance. In this case, be sure to go to the
[INK CONTROL] menu and select [INK RENEWAL FULL] to
perform maintenance. Failure to do this may result in mal-
function.

When the machine has not been operated for two weeks
➢Switch on the power every two weeks, even if the machine has been out of use. The [INK RENEWAL FULL] message appears, so
carry out maintenance as described in the previous section.
Message displayed: [INK RENEWAL NORMAL]
➢"Normal" maintenance does not require cleaning cartridges.
➢This message appears when 12 hours or longer have passed
since the last time maintenance was performed.
➢Pressing the [MENU] key makes the message disappear with-

Important Notes When Performing Overprinting
What is overprinting?
Overprinting refers to printing a white-ink undercoat first, and
then performing CMYK printing on top of the white ink (or vice
versa). The procedure may involve first printing only white ink,
then returning the media to its original position, and finally per-
forming CMYK printing.
Allow the ink to dry thoroughly.
➢Dry the ink sufficiently before you perform overprinting with
the next color. Performing overprinting before the ink has dried
enough may make attractive printing impossible or cause prob-
lems such as reduced weatherability.
➢Drying time differs according to various conditions, but as a
general guide you should use a media dryer and also allow
the media to stand for an additional 15 minutes.
Using the middle pinch rollers
➢The middle pinch rollers may smudge the printed surface when
the media is pulled back. When you perform overprinting, we
recommend securing the media in place using only two pinch
rollers (one on the left and one on the right).
Preventing misaligned colors
➢Because the media is pulled back between printing opera-
tions, color misalignment occurs between the white printing
and the CMYK printing.
➢We recommend that you set the [PREFEED] menu item to [EN-
ABLE]. This can help reduce color misalignment to a mini-
mum.
➢Use the machine in the recommended operating environment.
Also, carry out operations in a location having stable tem-
perature and humidity.
Important Notes When Using Transparent Media
Loading transparent media
➢Set the [EDGE DETECTION] menu item to [DISABLE]. Trans-
parent media cannot be loaded unless this setting is made.
Important notes on the amount of media remaining
➢When you use transparent media, the presence of media can-
not be detected. In such cases, printing operation does not
stop when the media runs out, and there is a chance that the
platen or the like may become soiled by ink or that ink may
get inside and damage the machine.
➢If media runs out while printing is in progress, immediately
press the [PAUSE] key to quit printing.
Using the middle pinch rollers
➢The pinch rollers damage media slightly, and on transparent
media this damage can be very noticeable. If such damage is
a concern, we recommend securing the media in place using
only two pinch rollers (one on the left and one on the right).
Automatic crop-mark detection
➢Automatic crop-mark detection may not be possible for some
media, such as transparent media. In such cases, perform align-
ment manually.
Important Notes When Using the Media Take-up Unit
➢The automatic media take-up unit can be used only in CMYK
printing.
➢Set the [FEED FOR DRY] menu item to [DISABLE].
➢Set the [PREFEED] menu item to [DISABLE].
➢Be sure to refer to the documentation for the take-up unit and
make the other settings as well.
The [FEED FOR DRY] menu item is a feature for a media dryer. It
prevents uneven drying by feeding the trailing edge of the printed
media to a dryer after printing has finished. Note, however, that
because media take-up is also performed, this menu item must
be set to [DISABLE] when the take-up unit is used.
