on the variable. It also performs a system reset.

The NVRAM initialization resets the following:

• All menu settings to factory default values

• Factory settings, such as formatter number, page counts, and

factory paper settings

To perform NVRAM initialization

1 Turn the printer off.
2 Press and hold G
3 Turn the printer back on, and continue to hold G

Ready, and Go lights turn on.

4 Release G

The device lights cycle from front to rear. The NVRAM initialization
runs until completion, when the device is in the Ready state.

PJL software commands

To set the following NVRAM variables:
Factory printer DEFAULT PAPER and copier/scanner factory default

paper size are set to the same value automatically.

Factory printer DEFA ULT LPARM:PCL SYMSET
Factory DEFAULT OEM bit
Factory DEFAULT PRINTPAGECOUNT
Factory DEFAULT SCANPAGECOUNT
Factory DEFAULT COPYPAGECOUNT

Default Quick Copy paper size is also stored in the scanner NVRAM,
but is changed only through the software or when set back to factory
default with a NVRAMINIT. Only Quick Copy image type and contrast
have a default value stored in NVRAM. They can only be changed
through the software or by NVRAMINIT, which returns them to a ROM
default value.

NVRAM PJL factory variables

To use the following commands, you need some method to send PJL
commands to the printer, either with a software tool or by copying a
binary file that contains the commands from the host using an
MS-DOS® box. For example, from the MS-DOS prompt:

copy /b filename lpt1

Here is an example of a file that uses one of the commands:

ESC%-12345X@PJL SET SERVICEMODE=HPBOISEID
@PJL ‘command’
@PJL RESET

Here is an example of using the NVRAMINIT command:

ESC%-12345X@PJL SET SERVICEMODE=HPBOISEID
@PJL NVRAMINIT
@PJL RESET

Note

Set SERVICEMODE before trying to set the variable, or you will not
archive the desired result. Also reset the PJL to be sure the

SERVICEMODE status is cleared.

To create these files, you need an editor that can insert the ESC
character or is able to copy it in from an existing file. If a software tool is
used, simply send the same strings in the same order as given for the
example files.

Recalibrating the copier/scanner

The optional copier/scanner automatically calibrates to the white sheet
opposite the image sensor at the beginning of each scan or copy job.

Keep the white sheet clean to make sure the optional copier/scanner
calibrates correctly.

LJ 2200 Service mode functions

In Service mode, the following can be performed:

• Print a Service mode self-test.

• Verify and set the page count.

• Set the cold reset default.

• Set the demo page = true/false.

• Set the diagnostic functions on or off.

Entering Service mode

Use PJL commands to enter Service mode and perform various Service
mode configurations. Users must use the exact character and case
specified for PCL printer commands.

The following are elements of a typical printer command:

• escape character (begins escape sequence)

• parameterized character

• group character

• value field (contains both alpha and numeric characters)

• termination character (uppercase)

Escape sequences can be combined into one escape sequence string.
Follow these important rules to follow when combining code:

1 The first two characters after the escape character (the

parameterized and group characters) must be the same in all of the
commands to be combined.

2 When combining escape sequences, change the uppercase

(termination) character in each individual escape sequence to
lowercase.

Note

The final character of the combined escape sequence must be
uppercase.

92 Chapter 2 – Service mode EN

Entering escape characters

Printer commands always begin with the escape character (ESC). The
following table shows how the escape character can be entered from
various MS-DOS programs.

Setting the page count

The page count is stored in the printer’s NVRAM. If it is necessary to
replace the formatter PCB, the page count should be reset to the
printer’s original page count to reflect the age of the print engine. Before
removing the old formatter PCB, print a self-test/configuration page to
verify the current page count of the printer.

might need to be reset when the formatter is replaced.
