Clean the rubber wheels really good with ArmorAll, the rubber and vinyl protector for cars, and let it DRY overnight.  It’s a miracle drug for LaserJet’s.

Subject: Scanning and Copying Secret


When scanning or copying thin paper, such as a magazine article,
where the print from the other side is coming through and showing
up on your copy, just place a black sheet of paper behind what you're
working on. The print on the back side blends into the black 
background and disappears.

Subject: Control your Printer from DOS!


Standard functions: Control character:
------------------- ------------------

Bell G
Line Feed J
Form Feed L
Carriage return M


1. Make a BAT file to cause a Form Feed (or any other function).

C:\>Copy con F1.BAT (Copy the following into a batch file called F1).
/ (press escape and return)
^L (Press control and L, then return)
^Z (Press control and Z, then return - this ends
the file)

This file, "F1.BAT" now contains; "escape code control L"


2. To make it work, make a BAT file that will send it to the printer as
as a text string.

C:\>Copy con FF.BAT (Copy the following into a batch file called FF).
Type F1.BAT>PRN (Type this string and return)
^Z (Press control and Z, then return - this ends
the file)

Now you can just type "FF" or "ff" from anywhere and cause your printer
to form feed.

Subject: Parallel Printer Cable


If you are trying to get a Parallel Printer to work and it locks up the 
Printer as soon as you connect the cable, and put it ON LINE, or you can't
control the printer when the power to the PC is off, open pin 16.

Pin 16 is not called out in standard tech manuals, but is connected to
to something on some accessory cards. If you suspect this, use a breakout
box to test this fix. If all is OK, I find it best to cut the lay on the
circuit board for pin 16. Just a small, 1/16 inch gap is all you need,
then if you ever need it back or you cut the wrong lay, you can reconnect
it with solder.

The PCL printer language is developed by Hewlett-Packard for
their printers (laser and inkjet). PCL versions are numbered
beginning with 1, the current version is 5e. Some words about PCL
history (from HP's Printer Language Technical Reference Manual):

PCL 1 Print and Space functionality is the base set of
functions provided for simple, convenient,
single-user workstation output.

PCL 2 EDP (Electronic Data Processing)/Transaction
functionality is a superset of PCL 1. Functions
were added for general purpose, multi-user system
printing.

PCL 3 Office Word Processing functionality is a
superset of PCL 2. Functions were added for high-
quality, office document production. (Printers: HP
DeskJet family)

PCL 4 Page formatting functionality is a superset of
PCL 3. Functions were added for new page printing
capabilities. (Printers: HP LaserJet II, HP
LaserJet IIP (PCL 4.5))

PCL 5 Office Publishing functionality is a superset of
PCL 4. New publishing capabilities include font
scaling and HP-GL/2 graphics. (Printers: HP
LaserJet III, HP LaserJet 4 (PCL 5e))

PCL 6 Arrived in 1999


PCL versions differ in functionality (e.g. font type support:
bitmap fonts, scalable fonts (Intellifonts, TrueType fonts),
raster graphic compression methods, HP-GL/2 graphic support).

PCL is the most widely spread printer language in the laser
printer market today. Most laser printer manufacturers use an
implementation of PCL 4 or PCL 5 for their printers.

PJL ("Printer Job Language") is developed also by Hewlett-Packard
to provide a method for switching parameters at the job level
(e.g. printer language), and for status readback between printer
and host computer. PJL may be used e.g. at the begin of a print
job for setting some job specific parameters like printer
language (PCL, PostScript or others), resolution (300 or 600
dpi), number of copies.

Note: not all HP printers support PJL commands. Sending such a
command to a printer not supporting it may cause the printout of
the command (in case of a PCL printer), for printers in
PostScript mode the command will cause a PostScript error and
prevent the job from printing.

PJL is currently supported by the following HP printers: LaserJet
IIISi, LaserJet 4 family, PaintJet XL300 and DesignJet.

More information about PCL and PJL may be found at HP's anonymous
ftp server ftp-boi.external.hp.com (located in Boise, Idaho, US).
For more information, look for deskjet/paintjet information in:
<ftp://ftp-boi.external.hp.com/pub/printers/djet_pjet_dwriter/doc/>
Laserjet information is found in:
<ftp://ftp-boi.external.hp.com/pub/printers/laserjet/doc/>

Available from HP are some technical manuals covering PCL and PJL
in depth:
- PCL 5 Printer Language Technical Reference Manual
(HP Part-No. 5961-0509)
- Printer Job Language Technical Reference Manual
(HP Part-No. 5961-0512)
- PCL/PJL Technical Quick Reference Guide
(HP Part-No. 5961-0511)

Subject:  Fusers in HP Laserjets II and III

The heater element is actually a quartz lamp. The other end of the fuser
has a circuit board that controls the heating, or voltage to the lamp.

To check the lamp remove the fuser assembly (remove four screws), and
turn the assembly over. On one end will be a circuit board with a bunch 
of contacts which control the voltage, on the other end is a white 
connector with two contacts. These go to the lamp. Check these two
contacts with an OHM Meter. If it is open, then the lamp is bad and
the fuser assembly must be replaced. If it is OK the reading will be
less than 2 ohms. If you have an error code 50/51 and the fuser tests
good, replace the power supply.

Subject:  Speed up Ink Jet Printers

An easy way to speed up printing on most color ink jet printers is to switch to gray mode printing for most of the time and switch to color only when you really need it.  This will save your color cartridges and should speed up printing by about four times.

This is easy to do:  Go to Start, Settings, Printers.  RIGHT Click on your printer and choose PROPERTIES.  Find the TAB that lets you change from Color to Gray Scale.

Do the same to change back to color
