Replacing the Printhead Cartridge
The following procedure describes how to remove the Printhead Cartridge from the printer.
NOTE: We recommend the use of nitrile powder-free gloves for this process.
1. Plug in the printer. Turn the printer’s Main Power Switch ON; then press the control panel’s
ON/OFF button. Wait about 45 seconds for the print engine to power-up (ON/OFF button will
illuminate).
2. Open the Top Cover.
3. Open the Toolbox utility.
4. Click on the button labeled “Release Printhead”;
located in the Advanced Buttons area [C] of the
User Interface screen.
The printer will run a partial deprime routine and
then the printhead latch will release so it can be
opened.
WARNING! If the printhead latch fails to release
do not force the latch open. Severe damage will
result. Contact technical support.
5. Open the Printhead Latch fully to disengage the ink couplings from the printhead cartridge.
6. Remove the old printhead as shown below. Tilt the cartridge back and then lift up to remove.
7. To help reduce ink spills; place the printhead into the old protective packaging and discard.
8. Once the old Printhead Cartridge has been removed; please refer to the section titled “Installing
the Printhead Cartridge”; to install the new Printhead Cartridge.
ATTENTION
If you experienced fuzzy print quality or an abrupt failure in a particular area of nozzles on
the previous printhead; we recommend that you have the service station
inspected/cleaned and the wiper roller replaced, before installing the new printhead. If not;
the chance of damage to the new printhead is greatly increased.
Service station maintenance and wiper roller replacement should only be performed by a
qualified/trained person.
WARNING
Never attempt to open the Printhead Latch manually, when in the closed/locked position.
Severe damage will result. Use the Release Printhead button from the Toolbox Utility.
