The front-panel display recommends reseating or
replacing a printhead
1. From the front panel, turn the power off then on.
2. Check the front-panel display message, if it shows the ready message, the printer is ready to print.
If the problem remains continue with the next step.
3. Remove the printhead, see
Remove a printhead on page 88.
4. Clean the electrical connections on the backside of the printhead with a lint free cloth. You can
carefully use a mild rubbing alcohol if moisture is needed to remove residue. Do not use water.
CAUTION: This is a delicate process and may damage the printhead. Do not touch the nozzles
on the bottom side of the printhead, especially not with any alcohol.
5. Reinsert the printhead, see Insert a printhead on page 91.
6. Check the front-panel display message. If the problem remains, try a new printhead.
Clean the printheads
As long as the printer is kept turned on, an automatic cleaning is performed periodically. This ensures
there is fresh ink in the nozzles and prevents nozzle clogs, which ensures color accuracy. If you have
not already done so, please see
The Image Diagnostics Print on page 133 before proceeding.
To clean the printheads, press the Menu key to return to the main menu and select the Image Quality
Maintenance menu icon
, then Clean printheads. If you have gone through the Image Quality
Diagnostic print process, you know which colors are failing. Select the pair of printheads which contain
the failing colors. If you are not sure which colors to clean, you can also select to clean all printheads.
Cleaning all printheads takes about nine minutes. Cleaning a single pair of printheads takes about six
minutes.
NOTE: Cleaning all printheads uses more ink than cleaning a single pair.
Clean the printhead drop detector
The printhead drop detector is a sensor that detects which nozzles on the printheads are not printing in
order to substitute them for good printing nozzles. If particles, such as fibers, hair or paper pieces, block
the sensor print-quality is affected.
