5.5 Adjusting the Head Switch
The head switches prevent printing from occurring when a printhead is open.
Adjust the head switches if the error message Head open appears in the display even though the printheads are
locked.
Danger!
Risk of death via electric shock!
Before opening the rear cover, disconnect the device from the mains supply and wait at lease one
minute until the power supply unit has discharged.

Notices!
Every print unit has its own head switch. The error message can be caused by both of the switches.
When the error message occurs wrongly check both switches.
1. Unplug the printer from the electrical outlet.
2. Remove the rear cover 2.2 on page 6.
3. Lock printheads.
4. Slightly loosen screws (1) of the head switch (2).
5. Move the head switch housing and switching lever (3) to a parallel position.
6. Screw down the head switch in this position.
7. Check whether the Head open message is still shown in the display. If this is the case, replace the switch with
cable.
8. Install the rear cover.
