1-4 Important Operating Notes
Important Operating
Notes
◆
UV CURE INK IS PERISHABLE.
Unlike other
inks used in wide format printing, UV cure ink
has a limited shelf life. Plan to rotate your ink
stock and use it promptly by the date printed on
the ink box.
◆
DO NOT POWER DOWN THE PRINTER. Constant vacuum at
the printheads is required to prevent ink from flowing from
the printheads when not printing. If the printer must be
powered down for shipping see “Extended Power Down and
Restart” on page 5-25, or apply auxiliary 24 volt power.
Caution
Do not switch off the UV lamp power supply
unless the lamps have fully completed their con-
trolled cool-down cycle
(with fans and heat extrac-
tion). Removing power from hot lamps can result in
overheating and permanent damage. If sudden
removal of power occurs, contact Océ Display Graph-
ics Systems Technical Services before starting the
printer again.
Caution
Do not connect any equipment to the line condi-
tioner for the UV power supply, except as specified
by Océ.
◆
To dab the printheads, use only Océ IJC700 UV Printhead
Flush. (See “Recover Missing Ink Jets” on page 5-7 for
instructions.) DO NOT USE ISOPROYPL ALCOHOL.
◆
The maximum diameter allowed on the takeup spool is 7.5
inches (190.5 mm) on a 3-inch core. When the takeup spool
has a diameter of 6.5-7.5 inches (165.0-190.5 mm), the con-
trol panel displays a warning about possible print quality
issues. The supply-takeup system can support rolls of up to
approximately 125 pounds (56.7 kg).
◆
The media supply may be wound either printed-side-out or
printed-side-in, but the takeup, if used, must be loaded
printed-side-in.
◆
The default head height set to 0.085 inches (2.2 mm) above
the media. (The space below the carriage will measure to
0.070 inches due to the printhead protection frame around
the outside of the carriage.)
