HP 4 Plus Manual

							Reset Menu 
Use Reset Menu function with caution. It can result in loss of
buffered page data or printer configuration data. Reset Menu is
activated by holding down both [Shift] and [Menu]  for up to 10
seconds  until RESE\f=MENU * appears. Use  [+] or  [-] to cycle through
items and  [Enter] to select the item. The reset is executed by
pressing  [On Line].
[Reset]
(and Menu
of Resets) A reset (
[Shift] + [Menu]) displays a  07 RESE\f, clears the printer ’s
page buffer, removes all temporary typefaces and macros, and makes
the current user-established defaults  “permanent. ” They will be the
default values until they are changed by the user. 
To access the Menu of Resets, hold down both  [Shift] and [Menu]  for
about 10 seconds until  RESE\f=MENU* appears in the display panel.
Use  [-] to cycle through the display choices, and  [Enter] to select the
option. Execute the reset by pressing  [On Line]. The printer responds
with a reset message for the choice selected.
The three
RESE\f=
choices are:  MENU* 
clears the page buffer, removes all temporary personality data
such as downloaded typefaces, and resets all printing environment
parameters (such as number of copies, paper size, etc.), and sets
user-selected defaults (such as MP tray default configuration) to their
factory defaults. Certain items, such as the display language or I/O
configuration, are not reset.  RESE\f=MENU clears only the active I/O
input buffer.
AC\fIVE I/O  clears the page buffer, removes all perishable personality
data such as temporary typefaces, and clears the input and output
buffers  for the active I/O only .
ALL I/O  clears the page buffer, removes all perishable personality
data such as temporary typefaces, and clears the input and output
buffers  for all I/Os .
* indicates factory default.

Figure 3-2 shows the menus and menu items available with the
basic printer configuration. Not all menu items are discussed in
this section. Only those items of specific interest from a service
standpoint, or items new to the printers are discussed in this
section. If options such as PostScript or a different I/O are
installed, new menu items automatically are added at the
appropriate location. For example, a PostScript Menu appears
following the PCL Menu.

							Printer Features
Some of the important features of the HP LaserJet 4, 4 Plus, and
LaserJet 5 printers are described below.
Page Protection (HP LaserJet 4 only)
NoteThe default is 
PAGE PRO\fEC\f=OFF*.   Unless you
frequently get  2\b PRIN\f OVERRUN  messages, you
may not need to set a value for page protection.
Page protection reserves additional memory for the page image
process, allowing the printer to create an entire page image in
memory before paper starts through the printer. The memory
required for page protection is dependent upon the resolution
selected: a 600-dpi page can take  4 times as much memory as a
300-dpi page. If you use page protection, set it for the size you
expect to use most often.  Be sure you have sufficient installed
memory for the option you select.  Complex graphics and
PostScript applications also require more memory than is
included in the standard printer configuration.
Note Unlike earlier HP LaserJet printers, page
protection and resolution can be set regardless of
memory installed in the printer. Be aware that
setting page protection 
ON will decrease the
amount of memory available for other memory
dependent features.
Configuration 3-13 
						

							Resource Saving (HP LaserJet 4 Plus and 5 only)
Resource Saving gives the printer the ability to save certain
entities such as permanent soft fonts, macros, symbol sets and
user-defined graphics patterns when the printer changes
personalities, resolutions or page protect modes. For example, if a
user switches the LaserJet 4 printer from PCL mode to
PostScript mode, all PCL soft fonts macros are lost. The HP
LaserJet 4 Plus/4M Plus printer would not clear these entities
from memory. When the user switches back to PCL from
PostScript all of the PCL entities would still be resident in the
HP LaserJet 4 Plus/4M Plus printer. Resource Saving can only be
accessed when the printer has the PostScript language installed
and a minimum memory configuration of 7 MB. If the printer has
a duplexer option, the minimum amount of memory necessary to
access Resource Saving is 13 MB.
The Resource Saving configuration is located in the Memory
Configuration Menu. Resource Saving can be set for three modes,
AUTO (default), ON, and OFF. Auto configuration sets the
Resource Saving for PCL and Postscript to a minimum value (400
KBytes) for each personality. Setting Resource Saving to ON
allows the user to determine how much printer memory will be
used for Resource Saving for the PCL personality and the
Postscript personality. The memory can be allocated in 100
KBytes increments. For example, if the user sets the Resource
Saving memory size to 200 KBytes, a total of 400 KBytes of
memory will be assigned to Resource Saving. 200 KBytes of
memory will be used for Postscript Resource Saving and 200
KBytes of memory will be used for PCL Resource Saving.
Turning Resource Saving OFF disables the Resource Saving
function and no memory is allocated to Resource Saving.
