Installing network cards
The following section explains how to install either an Ethernet (KX-PNBC5) 
or Token Ring (KX-PNBC6) network card (illustrated below) on the 
KX-P8420. It also describes how to configure the printer Setup when the 
new network card has been installed. 
To install the network card you will need to do the following:
•Remove the printer controller board from the back of the printer.
•Install the network card on the printer controller board.
•Replace the printer controller board.
•Configure the printer’s network setup.
IMPORTANT:
•To avoid electric shock ensure your hands are dry before touching the 
printer’s power plug.
•Ethernet (KX-PNBC5) or Token Ring (KX-PNBC6) network card
CAUTIONS:
•Do not drop or bend the network card.
•Do not touch the connector of the network card.
•Protect the network card from static electricity by keeping it in its anti-
static package until you are ready to install it.
•Avoid exposing the network card to direct sunlight, high temperatures, or 
humidity.
Before you begin this procedure, remove the printer controller board from 
the printer. For instructions, see “Removing and replacing the printer 
controller board” on page 193.

Margins and print area 
When the image is printed on the media, the image (print area) is a bit 
smaller than the media size. You may need to adjust the page margins in 
the application software to match the print area. 
The following table shows the page sizes, the largest print areas, and the 
margins for the media sizes supported on this printer.

Paper weight 
The printer is designed to work well with most types of paper. However, 
differences in paper may have significant effects on the quality of the print 
or the reliability of paper handling. It is strongly recommended that you 
always test paper before purchasing it to make sure it provides desirable 
performance.

							208 Appendix
n Types of paper to avoid
•
Extremely smooth or shiny paper or paper that is highly textured
•Letterhead imprinted with low temperature or thermography. These 
materials may transfer onto the fusing roller and cause damage. 
Any pre-printed paper should use inks compatible with 200°C (392°F) for 
0.1 second.
•Damaged or wrinkled paper, or paper with irregularities such as tabs, 
staples, etc.
•Multipart forms or carbonless paper
•Paper with a 25% or more cotton and/or fiber content
•Ink jet paper (It may transfer onto the fuser roller and cause damage.)
n Two-sided printing (Duplex printing)
Two-sided printing is possible by using the multi-purpose tray. However, 
you should not expect the same print quality and reliability that you get with 
one-sided printing. We strongly recommend that you follow the guidelines 
below.
•Do not load more than 50 sheets in the multi-purpose tray.
•Before loading paper in the multi-purpose tray, adjust it so that the edges 
of the media are lightly touching the media guides of the multi-purpose 
tray.
•Use heavier paper, at least 95 to 165 g/m2 (28 to 44 lbs. Bond) for reliable 
feed. Do not load a thin sheet of paper in the multi-purpose tray. It may 
cause a paper jam.
•It is strongly suggested to use color laser bond paper.
•Use multi-purpose tray for second side printing.
•Avoid printing photograph or graphic in solid color to prevent paper 
jamming. It may cause a damage to the printer.
•Before printing on the first side, set the unprintable area [at least 15 mm 
(0.59) in length] on the top of paper. (See below.)

It is strongly recommended 
that the sizes of photograph 
and graphic printed on the 
page are as small as 
possible. 
						

							209 Appendix
n Transparencies and labels
You may also print on transparencies and labels that are made for the 
printer. Panasonic has tested and found that the following work 
satisfactorily:
OHP transparency:3M CG3700
Labels:AVERY 5163, AVERY 5164, AVERY 5165, Avery L7163, 
Avery L7165, Avery L7166, Avery L7167, Avery L7168, Avery L7169
•Re-using transparencies that have been fed through the printer once (for 
example, after jams or if the transparency is ejected without being 
printed) can reduce the life of the consumables and paper path 
components.
•When using transparencies, if the print quality is poor, print on the other 
side.
•With any label stock, the labels must completely cover the backing 
material. 
Labels cover the entire backing material.
YES
The backing material is exposed.
NO 
						

							210 Appendix
n Envelopes
It is recommended that you print in black text only and purchase high quality 
#10 laser envelopes with diagonal seams, as shown in the diagram below:
High quality envelopes have the following characteristics:
•A thin, sharply creased leading edge
•Paper weight of 90 g/m 2 (24 lbs.)
•Flat, free of curls, wrinkles, nicks, etc.
NOTE:
•Wrinkle may occur in some case, even if high quality envelopes are used.
It is not recommended that you use envelopes with any of the following 
characteristics (using these may result in paper jams):
•Irregularly shaped envelopes
•Envelopes with curls, wrinkles, nicks, twists, dog-ears or other damage
•Envelopes with side seam construction
