◆ Purge — purges the printheads on the left side of the printer,
to help recover missing jets. Follow a purge with a manual
dab or blot of the printheads (do not wipe) with a lint-free
cloth.
◆ Lamps On/Off — allows you to manually power on or off the
lamps, instead of waiting for automatic operation.
◆ Sleep/Wake — Sleep detensions the takeup system (roll-fed
media), and powers down the UV lamps, printheads, car-
riage, and media drive motors, but maintains vacuum to the
printheads to prevent ink leakage. Wake tensions the takeup
system and powers up the printer components. The printer
goes into sleep mode automatically after 30 minutes, and
"wakes" automatically when a print job is received or a
printer operation is performed from the control panel.
In Sleep Mode, the carriage moves 0.25 inches (6 mm) once
per hour for three hours, then moves in the other direction
for three hours, and repeats this sequence until the printer is
restored from Sleep Mode. This prevents the formation of a
flat spot on the carriage bearings (wheels) when the printer
is in Sleep Mode for over 24 hours.
Caution
If printhead vacuum is lost during Sleep Mode, ink
will begin to seep from the printheads.
To prevent ink leakage during an unexpected power
outage, Océ strongly recommends using the vac-
uum/pressure system's 24 volt auxiliary power supply
and connecting it to an uninterruptable power sup-
ply (UPS). Affordable and reliable UPS units are avail-
able with 100-240 VAC, 50/60 Hz, minimum of 15
watts. See Appendix A for details. It is not necessary
to connect the entire printer to a UPS, only the vac-
uum/pressure system needs to be connected to
avoid ink seepage.
◆ Access Heads — moves the printhead carriage out from the
service station to the opposite end of the printer. This is the
same functionality as the Access Printheads option on the
Maintenance menu. The UV parking station must be re-
moved first to avoid the possibility of the carriage striking it.
◆ Media Wizard — provides direct access to the printing
parameters stored for the currently loaded media (see
"Media Wizard" on page 3-41 for details).
◆ Load (visible when the supply and takeup are unloaded) —
loads roll-fed or sheet-fed media. See "Loading Roll-Fed
