Problem Resolution
There are two methods that can be used to access the Service and Factory Menu as follows:
D Press the * and 7 buttons simultaneously while powering on the HP OfficeJet Series 300.
D From the “Enter Header Number” display, first use the Backspace button to erase the currently
displayed header number (if present), then press the Redial/Pause, *, Redial/Pause, 2, 3, 2 and
Enter/Save buttons in sequence.
Two other menu headings will also appear. The Regulatory Settings and the Underware menu headings will be seen as
well as the Service and Factory Menu headings. Do NOT attempt to access or use the Regulatory Settings or
Underware menus. These should only be accessed by HP factory personnel.
Once the Service and Factory Menu has been accessed, it will remain part of the main menu structure until the HP
OfficeJet Series 300 is powered OFF. Cycling the power OFF and then ON will return the main menus back to normal
(the Service and Factory Menu will no longer be accessible). To reaccess the Service and Factory Menu, this
procedure will need to be restarted.
When the Service and Factory Menu is made accessible, the following features will change:
D The menu settings report will print out all available menu structures.
D The Self Test report will also print out a complete parameter listing (firmware revision dependent).
D An error report will include a more detailed listing of the diagnostic code.
The same method used to navigate and select user menu functions is also used for the Service and Factory Menu. All
the various functions and tests available in the Service and Factory Menu are listed in the following paragraphs.
Show Code Revision: The current firmware revision level is displayed for 5 seconds.
Show Failure Code: The last system error failure code is displayed for 5 seconds.
Factory Defaults: Sets all user and parameter settings to default. Once selected, pressing the Start/Copy
button will continue the default procedure. Pressing any other button will exit the selection.
The HP OfficeJet Series 300 must be powered OFF and then ON to begin using the default
values. This menu item may also be selected by pressing the * and 1 buttons
simultaneously while powering the unit ON.
Set Panel Language: Will set the front panel display to the selected language option. Available options are
English, Dutch, French, and German. The default language setting is determined by the Line
Interface Unit installed as prescribed by the unit’s country of destination for shipment.
Print Calib Chart: The distance between the page detect sensor and the location of the scanner will vary
between machines due to parts tolerances. This variation affects the top scanning margin.
The scanner position calibration will adjust the top margin. The Print Calib Chart is used for
this procedure and contains the following features:
1. A check to see if a calibration is successful or needed
2. Instructions on how to perform the calibration
3. Calibration scale used to select the correct parameter value
To check if a calibration is needed, first print the Calibration Chart. Then cut the top of the
chart along the dotted line. Set the HP OfficeJet Series 300 copy reduction setting to 100%.
Make one copy of the chart by feeding the top end first into the document feeder. If the
hour-glass figure printed on the chart is either completely visible or not visible at all, a
calibration is needed. Ideally, one–half of the hour-glass figure should be visible. A detailed
description of this procedure is provided in chapter 4 of this manual.
