This equipment is certified as a Class 1 laser product as defined in IEC 60825-1+A2: 2001 
specifications under the U.S. Department of Health and Human Services (DHHS) Radiation 
Performance Standard according to the Radiation Control for Health and Safety Act of 1968. This 
means that the equipment does not produce hazardous laser radiation.
Since radiation emitted inside the equipment is completely confined within protective housings

Optional paper tray 
(PF-P10)
B
An optional lower tray can be installed, and it 
can hold up to 250 sheets of 80 g/m
2 paper.
When an optional tray is installed, the 
machine can hold up to 550 sheets of plain 
paper. If you want to buy an optional lower 
tray unit, contact your KONICA MINOLTA 
dealer.
 
For setup, see the instructions that we have 
supplied with the lower tray unit.
Memory boardB
This machine has 64 MB of standard memory 
and one slot for optional memory expansion. 
You can expand the memory up to 576 MB by 
installing small outline dual in-line memory 
modules (SO-DIMMs). When you add the 
optional memory, it increases the 
performance for both copier and printer 
operations.
In general, the machine uses 
industry-standard SO-DIMMs with the 
following specifications:
Type: 144 pin and 64 bit output
CAS latency: 2
Clock frequency: 100 MHz or more
Capacity: 64, 128, 256 or 512 MB
Height: 31.75 mm
Dram Type: SDRAM 2 Bank
For purchasing information and part numbers 
visit the Buffalo Technology website:
http://www.buffalo-technology.com/
Note
• There might be some SO-DIMMs that will 
not work with the machine.
• For more information, contact your 
KONICA MINOLTA dealer.

Installing extra memoryB
aTurn off the machine’s power switch. 
Unplug the telephone line cord.
bDisconnect the interface cable from the 
machine, and then unplug the power 
cord from the electrical socket.
Note
Be sure to turn off the machine’s power 
switch before you install or remove the 
SO-DIMM.
 
cRemove the SO-DIMM cover and 
interface access cover.
 
 
dUnpack the SO-DIMM and hold it by its 
edges.
IMPORTANT
To prevent damage to the machine from 
static electricity, DO NOT touch the 
memory chips or the board surface.
 
eHold the SO-DIMM by the edges and 
align the notches in the SO-DIMM with 
the protrusions in the slot. Insert the SO-
DIMM diagonally (1), then tilt it toward 
the interface board until it clicks into 
place (2).
 
fPut the interface access cover and the 
SO-DIMM cover back on.
gPlug the machine’s power cord back into 
the electrical socket first, and then 
connect the interface cable. 
hPlug in the telephone line cord. Turn on 
the machine’s power switch.
Note
To make sure that you have installed the 
SO-DIMM properly, you can print the user 
settings page that shows the current 
memory size. (See How to print a report 
on page 71).

TroubleshootingC
If you think there is a problem with your machine, check the chart below and follow the 
troubleshooting tips.
Most problems can be easily resolved by yourself. If you need additional help, KONICA MINOLTA 
offers the latest FAQs and troubleshooting tips. Visit us at http://konicaminolta.com/. 
If you are having difficulty with your machineC
If you think there is a problem with the way your faxes look, make a copy first. If the copy looks 
good, the problem may not be your machine. Check the chart below and follow the troubleshooting 
tips.
Troubleshooting and routine 
maintenance
C
Printing or receiving faxes
DifficultiesSuggestions
Condensed print
Horizontal streaks
Top and bottom sentences are 
cut off
Missing linesUsually this is caused by a poor telephone connection. If your copy looks good, 
you probably had a bad connection, with static or interference on the telephone 
line. Ask the other party to send the fax again.
Poor print quality See Improving the print quality on page 117.
Vertical black lines when receiving The corona wire for printing may be dirty. Clean the corona wire. (See Cleaning 
the corona wire on page 140.)
The sender’s scanner may be dirty. Ask the sender to make a copy to see if the 
problem is with the sending machine. Try receiving from another fax machine. 
If the problem continues, call your dealer for service.
Received faxes appear as split or 
blank pages.If the received faxes are divided and printed on two pages or if you get an extra 
blank page, your paper size setting may not be correct for the paper you are using. 
(See Paper Size on page 20.) 
Turn on Auto Reduction. (See Printing a reduced incoming fax on page 45.)
Telephone line or connections
DifficultiesSuggestions
Dialling does not work. Check for a dial tone.
Change Tone/Pulse setting. (See the Quick Guide.)
Check all line cord connections.
Check that the machine is plugged in and switched on.
If an external phone is connected to the machine, send a manual fax by lifting the 
handset of the external telephone and dialling the number. Wait to hear the fax 
receiving tones before pressing Start.

C
The machine does not answer 
when called.Make sure the machine is in the correct receive mode for your setup. (See 
Receiving a fax on page 41.) Check for a dial tone. If possible, call your machine 
to hear it answer. If there is still no answer, check the telephone line cord 
connection. If you do not hear ringing when you call your machine, ask your 
telephone company to check the line.
Sending faxes
DifficultiesSuggestions
Poor sending quality. Try changing your resolution to Fine or S.Fine. Make a copy to check your 
machine’s scanner operation. If the copy quality is not good, clean the scanner. 
(See Cleaning the scanner on page 138.)
Transmission Verification Report 
says ‘RESULT:ERROR’.There is probably temporary noise or static on the line. Try sending the fax again. 
If you are sending a PC Fax message and get ‘RESULT:ERROR’ on the 
Transmission Verification Report, your machine may be out of memory. To free 
up extra memory, you can turn off fax storage (See Turning off Remote Fax 
Options on page 63), print fax messages in memory (See Printing a fax from the 
memory on page 46) or cancel a delayed fax or polling job (See Checking and 
cancelling waiting jobs on page 39). If the problem continues, ask the telephone 
company to check your telephone line.
If you often get transmission errors due to possible interference on the telephone 
line, try changing the Compatibility setting to Basic(for VoIP). (See 
Telephone line interference on page 124.)
Vertical black lines when sending. Black vertical lines on faxes you send are typically caused by dirt or correction 
fluid on the glass strip. (See Cleaning the scanner on page 138.)
Handling incoming calls
DifficultiesSuggestions
The machine ‘Hears’ a voice as a 
CNG Tone.If Fax Detect is set to On, your machine is more sensitive to sounds. It may 
mistakenly interpret certain voices or music on the line as a fax machine calling 
and respond with fax receiving tones. Deactivate the machine by pressing 
Stop/Exit. Try avoiding this problem by turning Fax Detect to Off. (See Fax Detect 
on page 44.)
Sending a Fax Call to the machine. If you answered on an external or extension telephone, press your Remote 
Activation Code (default setting is l51). When your machine answers, hang up.
Custom features on a single line. If you have Call Waiting, Call Waiting/Caller ID, Caller ID, Voice Mail, an 
answering machine, an alarm system or other custom feature on a single 
telephone line with your machine, it may create a problem sending or receiving 
faxes.
For Example: If you subscribe to Call Waiting or some other custom service and 
its signal comes through the line while your machine is sending or receiving a fax, 
the signal can temporarily interrupt or disrupt the faxes. KONICA MINOLTA ECM 
feature should help overcome this problem. This condition is related to the 
telephone system industry and is common to all devices that send and receive 
information on a single, shared line with custom features. If avoiding a slight 
interruption is crucial to your business, a separate line with no custom features is 
recommended.
