Replace a defective printhead
How to place a printhead
1. Remove the protective tape from the new printhead.
Note: Do not touch the contact and nozzle areas of the printhead after you remove
the protective tape.
2. Place the new printhead in the printhead holder.
The printhead only fits in one way.
3. Close the printhead cover.
4. After you replaced the defective printhead, press the softkey for 'Next'
5. The screen displays the message 'Make sure that all head covers are properly
positioned.'
Press the key for 'Done'.
The screen displays the message 'Close top cover.'
6. Close the top cover.
The screen displays the message 'Carriage moving to home position...'
7. The screen displays 'Calibrating...'.
The calibration process takes several minutes.
You can stop the calibration process at any time. Press the key for 'Cancel' to stop the
calibration process.
Note: If you cancel the calibration, the printer restarts the calibration process when
a new print job starts.
Note: If the printer rejects the new printhead during the 'Replace printhead'
procedure, remove the printhead, clean the contact area with a lintfree cloth and
re-insert the printhead.
Note: Also check the maintenance cassette after you have replaced a printhead. (see
‘How to remove the maintenance cassette’ on page 257) Check if all wipers are
present and clean. Excessive ink remains on the wipers can damage the printheads.
Wipe the wiper blades with a moist cloth to increase the lifetime of the printheads.
