8. PERIODIC MAINTENANCE
The objective of periodic maintenance is to ensure reliable operation of the printer.
8.1. PURGING/VENTING THE PRINTHEAD
Purging functions are not available to operator ‑type users.
The printhead purging/venting can be done by instructed persons .
Printhead purging/venting is disabled if the printer reported a warning about critically low ink in the bot -
tle.
Tools required:
‑ a sprayer with wash‑up (Part No. XS21602 ),
‑ protective gloves that are resistant to ink/wash‑up,
‑ safety goggles,
‑ absorbent material or a metal vessel for collecting waste,
‑ a cross head screwdriver,
‑ optional drip molding (an accessory; Part No. P513324 ).
The objective of printhead purging/venting is to:
– Improve print quality by clearing slightly clogged nozzles and cleaning the nozzle plate in the print -
head,
– Vent the printer after it has been transported or a bottle has been replaced.
The purging/venting consists of the opening of all nozzles at the same time and jetting of ink through
the nozzles under pressure.
The jetted ink flows down the nozzle plate (optionally along drip molding
5c - see Fig. 62 on page 150 )
to drip rail 3b , and then it is collected by the drip system and reaches waste bottle 3a .
Two printhead purging/venting modes are available:
– short purging lasting about 2 seconds ,
– long purging lasting about 85 seconds ,
It is advisable to follow the printhead purging/venting procedure with the application of optional drip
molding
5c , which is part of a double‑sided accessory (Part No. P513324 ). If no drip molding is used,
the ink outlet from the printhead (from the nozzle plate) must be secured with absorbent material.
To prepare the printer for the printhead purging/venting procedure with the use of an optional drip
molding (the recommended method):
1. If the printer is printing, press the icon on menu bar C (see Fig. 43 on page 52 ) on the main
screen to pause printing.
