Empty the Waste Ink Tray

Introduction

The waste ink tray is located below the ink spit tray. It accumulates waste ink from printhead spitting, and from the AMS.

About this task

Empty the waste tray weekly. The capacity of the waste tray is approximately 1.5 liters.

Equipment needed

Cloth or paper towel
Foam Tipped Swab or Cloth-Poly Wipe
An empty semi-transparent 1.5 liter plastic container
A plastic tub that can hold the 1.5 liter container and catch any ink spilled during draining
A plastic funnel
Nitrile Gloves, a lab coat and safety glasses with side shields to protect users from contacting the ink

CAUTION

UV-curable inks contain chemicals which can lead to sensitization with prolonged or repeated exposure to skin. These chemicals inside the UV ink can begin to penetrate the gloves in less than 10 minutes. Since they have no pigment, exposure is not obvious. Therefore, Canon recommends that only approved nitrile gloves are used for a maximum of 10 minutes after being contaminated with ink and never reused. Damaged gloves should be changed immediately.

Procedure

Put the plastic tub on the floor to catch any drips while the tray is emptied.
Place a suitable empty container that holds at least 1.5 liters into the tub. Insert a funnel.
Rotate the waste valve knob counter-clockwise until the white line is vertical to start the flow of waste ink.
Shut off the valve when ink no longer drains out (or if the container becomes full). Use a piece of cloth or paper towel to wipe the valve clean.
NOTE
If ink has dried in the waste valve from previous draining, it may be necessary to carefully use a significant amount of force to open the valve.
Use a swab to thoroughly clean the inside of the valve tip. Any ink not removed from the valve can drip out later when the printer is in motion.
Dispose of the waste material in a suitable, environmentally-friendly manner, following all local laws and regulations.
