To upgrade firmware:
The MFP has remote firmware update (RFU) capability. Use the information in this section to upgrade the MFP firmware. The overall process involves the following steps:
1 Determine the current level of firmware that is installed on the MFP.
2 Go to the HP Web site and find out whether a firmware update is available. If an update is available, download the latest firmware to your computer.
3 Transfer the new firmware from your computer to the MFP.
Determining the current level of firmware
To determine the current level of firmware, view the configuration information on the MFP control panel. To view the configuration information, follow these instructions.
1 Press MENU.
2 Touch INFORMATION.
3 Touch PRINT CONFIGURATION. The configuration page prints.
4 The firmware datecode is listed in the section called Device Information. The firmware datecode has this format: YYYYMMDD XX.XXX.X. The first string of numbers is the date, where YYYY represents the year, MM represents the month, and DD represents the date. For example, a firmware datecode of that begins with 20040225 represents February 25, 2004.

Tips for a great answer:
Thanks for using FixYa. To start with try to blow
compressed air around the lens cover so that if there is any dirt it cleans if
off. You can also stick a thin strip of paper between the lens shutter and the
outer support ring & move it in a way that it clears the debris that's
stuck in there. If still the issue is not resolved then you'll have to replace
the lens assembly & lens mechanism to fix this issue. It is recommended to
be done by a professional. Please do rate the solution if the issue is resolved
or post a comment for further assistance.
