Task Description

Interval: Weekly or as needed
Clean pinch rollers Gently dry wipe or blow away dust buildup.
Do not use any fluids to clean the pinch and
grit rollers. Deposits of these fluids could
form on the print media, causing streaks in
printed output.
To remove ink, use a minimal
amount of isopropyl alcohol and dry thor-
oughly before printing again.
Clean carriage rail and bearings (page 5-4) Inspect for dust buildup, clean if necessary (see
“Clean the Rail and Bearings” on page 5-4).
Clean the encoder strip Inspect for dust buildup, wipe if necessary with
Océ IJC700 UV Print Head Flush, follow with
isopropyl alcohol. Encoder must be fully dry
before printing.
Cured ink buildup on the encoder strip can-
not be removed without damaging the
encoder strip. Clean ink spills immediately. If
cured ink buildup on the encoder strip
causes printing errors, contact your Autho-
rized Service Provider or Océ Display Graph-
ics Systems Technical Support for a
replacement.

using a scraper or razor blade, especially near
the right and left edges when printing edge-to-
edge.

To recover jets with a purge and wipe, see
“Recover Missing Ink Jets” on page 5-7.
