Empty Ink Waste Trays

Introduction

There are two waste trays. The Purge Waste Tray is located under the Maintenance station. It catches ink purged from either Manual maintenance or Automated printhead maintenance. The Spit Waste Tray is located below the ink spit catcher. It accumulates waste ink from printhead spitting.

About this task

Empty both waste trays weekly.

CAUTION

Wear gloves when contact with ink or maintenance materials is possible. Gloves should always overlap sleeves. Follow the ink related Safety Data Sheets (SDS) guidelines carefully in order to ensure maximum safety. For example use Ansell Microflex 93-260 gloves, which offer a protection against UV inks and flush up to one hour. Pollution with other chemicals can shorten the protection time against UV inks and flush.

Wear eye protection as prescribed in this document when performing a task or action in this area.

CAUTION

UV inks and flush liquids can be harmful if not properly handled. Follow always the Safety Data Sheets (SDS) guidelines carefully in order to ensure maximum safety.

NOTE

Although the carriage is oriented so that the nozzles spit into the slots in the spit catcher, some ink will find its way onto the flat surfaces. Open the maintenance drawer to check the surface of the spit catcher daily. If you see any ink wipe it up with a clean cloth or paper towel.

Equipment

Foam Tipped Swab or Cloth-Poly Wipe
An empty semi-transparent 1.0 liter plastic container for the Spit Waste tray
An empty semi-transparent 5 liter plastic container for the Purge Waste tray
Two plastic funnels: one small and one large (see photos)
A plastic basin that can hold both containers and also catch any ink spilled during draining

Procedure

To empty the Purge waste tray first slide the maintenance drawer open.
Put the plastic basin in place on the floor to catch any drips while the tray is emptied.
Place a suitable empty container that holds at least 5 liters in the plastic basin with a large funnel placed under the Purge waste tray drain valve.
Align the funnel to the waste valve so that the ink will go inside the funnel and waste container when the valve is opened.
Rotate the waste valve knob counter-clockwise until the white line is vertical to start the flow of waste ink.
Wait for all of the waste ink to drain. If necessary, empty or use a second waste container.
NOTE
Tip:

If ink has dried on the waste valve from previous draining, it may be necessary to carefully use a significant amount of force to open the valve..
Shut off the valve when ink no longer drains out (or if the container becomes full).
Rotate the purge waste tray valve knob clockwise until it is fully closed and the white line is horizontal.
When the ink stops dripping, use a swab to wipe the inside of the valve tip clean as some ink can remain inside and drip out later when the printer is in motion.
With the Maintenance station drawer still open, hold a 1.0 liter container with a small funnel under the Spit waste tray valve.
Rotate the spit tray waste valve knob counter-clockwise until the white line is horizontal and the ink begins to flow out.
When the ink stops dripping out, rotate the spit tray waste valve knob clockwise until it is fully closed and the white line is vertical.
With the valve closed, use 3 swabs to thoroughly clean the inside of the valve tip.
Empty the 1 liter container into the larger container that holds the Purge waste ink.
Dispose of the waste ink and other contaminated material in a suitable, environmentally-friendly manner.
