Clean the Quartz Windows 6-21
1. ALLOW THE LAMPS TO COOL COMPLETELY BY FIN-
ISHING ALL PRINTING, AND WAITING FOR AUTOMATIC
SHUTOFF OR PRESSING THE “LAMPS OFF” BUTTON
ON THE CONTROL PANEL.
Do not perform this procedure when the lamps are on or
have not cooled completely.
2. From the Front Page screen of the control panel, press the
Tools key, then select Maintenance > Access Printheads.
The printhead carriage moves to the access position at the
service end of the printer. You will now be able to access the
service-end quartz windows from below the carriage.
Access the user-end quartz windows with the carriage at the
user end (after removing the drip tray).
3. Moisten a lint-free cloth with HP Scitex MF50 Flushing Solu-
tion, and wipe the quartz plates to moisten, soften, and
remove the cured ink and dust.
Any ink and dust present will be very hard cured, so you
may need to allow the buildup to soak. Then scrub with a
non-metallic scouring pad (to avoid scratching the window),
or scrape with a razor blade scraper.
4. After all of the ink and dust has been removed, wipe the
quartz windows clean with a lint-free cloth moistened with
HP Scitex MF50 Flushing Solution.
5. With a new lint-free cloth, dry-polish the quartz windows to
ensure that no smearing or residue remains.
6. If the carriage is at the service end, from the Front Page
screen of the control panel, press the Access Heads key.
The printhead carriage moves back to the wiping station.
