Symptom
Possible cause
Corrective measure
A blank sheet of media is printed or the printed image is faded.
The printer did not receive data.
Check print data.
The environment conditions do not meet the printer specifications.
Use the printer in the specified environmental conditions (temperature and humidity).
Media settings are incorrect.
Check the media settings.
Parts of a drawing are missing or the print is unclear.
Foreign objects are attached to the head.
Clean the printhead from the PH.RECOVERY menu.
The low printing ratio pattern is printed continuously at high temperature environment.
Set the printhead mode to HIGHLIGHT.
The print is blurred.
The media has been loaded the wrong side up.
Check whether the media is loaded correctly.
The media settings are incorrect.
Check the media settings.
The media edge guard or fan guard lever are not set correctly.
Set the media edge guard or fan guard lever correctly.
The heater temperature is too low.
Increase the heater temperature.
The print is stained.
The leading edge of the media is curled.
Check whether the leading edge of the media is curled. If it is curled, cut the leading edge.
The media is slightly folded or crumpled.
If the media is crumpled, feed the media and cut off the crumpled part of the media.
The platen is stained.
Clean the platen.
The first part of a printed image is missing.
Environment temperature.
Use the printer in the specified environmental conditions.
Parts of a printed image are missing even after head cleaning is performed repeatedly.
The nozzle is clogged.
Wash the printheads.
Poor print quality cannot be improved even when the cleaning is performed.
The cap or wiper is stained.
Check for stains on the cap and wiper. If they are stained, clean them.
There is banding on new media
The printer requires calibration for the new media.
Adjust the printer settings for the new media.
There is banding on media that has been calibrated and did not give banding before.
If one of the following is true, try the corresponding solution and if banding has not disappeared then go to the next possible cause and solution:
  1. The file that is printed:
    1. Is new
    2. Is not new
  2. The print mode:
    1. has changed
    2. has not changed
  3. Normal printhead recovery:
    1. Did not improve banding
    2. Improved banding
  4. Strong printhead recovery:
    1. Did not improve banding
    2. Improved banding
Try one of the following solutions:
    1. Try using a file that did not give banding. If banding does not disappear, then see the next possible cause.
    2. Check that the same print mode as before is used.
    1. Try using the same print mode. If banding does not improve, then try a new roll of media. If banding is still there, call HP support.
    2. Try normal printhead recovery. If banding improves, repeat normal printhead recovery until no improvement is seen and banding is still present. Call HP support.
    1. Print the IQ print and check whether there are any printhead nozzles not working. If some printheads are not working, try strong printhead recovery for the affected printheads.
    1. Call HP support
    2. Repeat normal printhead recovery until no improvement is seen and banding is still present. Call HP support.
