3-14 Capping the Printheads

Uncap the Printheads Uncapping the printheads is one component of the Wake func-

tion, which reverses the Sleep function:

◆ The printer leaves standby mode: the heaters are switched

on, and the supply & takeup system is tensioned (loaded).

◆ The OHS is enabled, which turns on power to the pumps.

◆ When you manually disengage the capping levers, the cap-

ping pad sensor is detected and the control panel enables all

functions and displays the Sleep key.

Tip

Since some ink may spill from the film-wrapped cap-

ping station, wear latex gloves to prevent staining

your hands during this procedure.

1. Press the Wake key on the Front Page screen on the control

panel.

The control panel asks you to confirm that you want to

uncap the printheads.

2. Press the

! (Proceed) key to uncap the printheads.

The control panel prompts you to disengage the capping sta-

tion pad.

3. Disengage the capping station.

Have a paper towel ready to blot any cleaning fluid that has

escaped from the printheads during capping. If the capping

film was applied as directed, most of the fluid should run

off the capping film into the drip tray.

Grasp the two capping pad levers, and simultaneously push

them toward the back of the printer to lower the capping sta-

tion.

4. Remove and discard the capping film.

Carefully remove the wrap to avoid spilling ink on the floor

or yourself.

5. To access the heads for cleaning, remove the capping station

assembly by pulling it forward and out of the printer.
