Remove Ink and Ink Waste

Introduction

How often you need to perform the following checks and procedures will vary, depending on printer usage and work habits.

Remove Ink from Table

Clean ink from the table whenever necessary. Once UV ink is cured, the best method for removing it from the table is to  use 
the provided scraper (it is also possible to achieve good results with a razor blade  that is set into a handle/holder). Be careful 
not to scratch the aluminium surface of the  table when scraping off the cured ink.

Unplug Vacuum Holes 

The vacuum holes in the table surface may become plugged with ink and thus reduce the  efficiency of the vacuum. To clear 
the holes, use an 0.8mm diameter rigid material (e.g.,  a paper clip) to ream them out, as required (this is not likely a daily 
task, but must be  performed as needed).

Check Waste Bottle

Check the waste bottle periodically and empty, if needed  (although this is not  necessary every day as you will be notified 
by the control panel display when it is nearly full).

Required tools

Table Scraper (3012002368)

Poly-Wipe Cloth (0505-0283)

Butyl Gloves (3010101760)

Note:

When scraping ink off the table be sure to remove all of the dry ink particles.  Use a vacuum and a wet lint free cloth 

to ensure no debris is left on the table  that could be picked up by a print head.

How to Remove Ink

1.

Scrape any cured ink from the surface of the table with the supplied scraper (or a razor blade in a holder).

2.

Use a vacuum cleaner to remove the scraped particles of ink and any other debris on the table surface.

3.

Use a lint-free cloth soaked in isopropyl alcohol to ensure that the table surface is clear of any remaining particles.

How to Unplug Vacuum Holes

1.

Identify any vacuum holes that are plugged with ink.

2.

With an 0.8mm diameter rigid material (e.g.,  a paper clip), ream out any of the holes that have been plugged.

3.

Clear any resulting debris with a vacuum cleaner or a wet lint-free cloth.

How to Empty the Waste Bottle

1.

Remove the waste bottle from the bracket and pour the waste into a suitable  container for disposal. 

2.

Put a cloth or paper towel in place to catch any drips while the bottle is emptied.

3.

Replace the empty container by fitting it into the bracket.

4.

Ensure that the lid is securely screwed on to the waste bottle.
