HP (Hewlett-Packard) CP4005 User Manual

  Control panel settings work incorrectly

The printer control panel display is blank or is not lit, even when
the fan is running.

Fans might run while the printer is in standby mode (off). Press
the printer’s on/off button to turn the printer on.

Printer settings in the printing software application or printer
driver differ from the printer control panel settings.

Confirm that the settings in the application and printer driver
are appropriate, because the application settings override the
printer driver and control panel settings, and the printer driver
settings override the control panel settings. For more
information, see 

Control panel settings were not correctly saved after they were
changed.

Reselect the control panel settings and then press  . An
asterisk (*) should appear to the right of the setting.

The 

Data

 indicator light is lit, and there are no pages printing. Buffered data exists in the printer. Press   to print the buffered

data using current control panel settings and activate the new
control panel settings.

If the printer is on a network, another user might have changed
printer control panel settings.

Consult the network administrator to coordinate changes to
printer control panel settings.

  Unable to select optional Tray 3

Optional Tray 3 does not appear as an option on the
configuration page or on the control panel.

Optional Tray 3 appears available only if it is installed. Verify
that the tray is correctly installed.

Optional Tray 3 does not appear as available in the printer
driver.

Verify that the printer driver configuration recognizes optional
Tray 3. For more information, see
