The machine prints unexpectedly 
or it prints garbage.Pull out the paper tray and wait until the machine stops printing. Then turn off 
the machine and disconnect from the power for several minutes. (The 
machine can be turned off for up to 60 hours without losing faxes stored in the 
memory.)
Check the settings in your application to make sure it is set up to work with 
your machine.
If you are using the parallel port connection, check that the port is KONICA 
MINOLTA bizhub 20 and not LPT1.
The machine prints the first couple 
of pages correctly, then some 
pages have text missing.Check the settings in your application to make sure that it is set up to work with 
your machine.
Your computer is not recognising the machine’s input buffer’s full signal. Make 
sure that you connected the interface cable correctly. (See the Quick Guide.)
The headers or footers appear 
when the document displays on the 
screen but they do not show up 
when it is printed.There is an unprintable area on the top and bottom of the page. Adjust the top and 
bottom margins in your document to allow for this.
The machine does not print on both 
sides of the paper even though the

Paper handling difficulties
DifficultiesSuggestions
The machine does not load paper.
The LCD shows No Paper or a 
Paper Jam message. If there is no paper, load a new stack of paper into the paper tray.
If there is paper in the paper tray, make sure it is straight. If the paper is curled, 
you should straighten it. Sometimes it is helpful to remove the paper, turn the 
stack over and put it back into the paper tray.
Reduce the amount of paper in the paper tray, and then try again.
Check that the MP tray mode is not chosen in the printer driver.
If the LCD shows Paper Jam message and you still have a problem, see 
Paper jams on page 131.
The machine does not feed paper 
from the MP tray.Fan the paper well and put it back in the tray firmly.
Make sure that MP tray mode is chosen in the printer driver.
How do I print on envelopes? You can load envelopes from the MP tray. Your application must be set up to print 
the envelope size you are using. This is usually done in the Page Setup or 
Document Setup menu of your application. (See your application’s manual for 
more information.)
What paper can I use? You can use thin paper, plain paper, thick paper, bond paper, recycled paper, 
envelops, labels and transparencies that are made for laser machines. (For 
details, see Acceptable paper and other print media on page 12.)
There is a paper jam. (See Paper jams on page 131.)
Print quality difficulties
DifficultiesSuggestions
Printed pages are curled.Low quality thin or thick paper or not printing on the recommended side of the 
paper could cause this problem. Try turning over the stack of paper in the 
paper tray.
Make sure that you choose the Paper Type that suits the print media type you 
are using. (See Acceptable paper and other print media on page 12.)
Printed pages are smeared. The Paper Type setting may be incorrect for the type of print media you are using, 
or the print media may be too thick or have a rough surface. (See Acceptable 
paper and other print media on page 12 and Basic tab in the Software User’s 
Guide on the CD/DVD-ROM.)
Printouts are too light.If this problem occurs when making copies or printing received faxes, set 
Toner Save mode to Off in the machine menu settings. (See Toner Save 
on page 24.)
Set Toner Save mode to Off in the Advanced tab in the printer driver. (See 
Advanced tab in the Software User’s Guide on the CD/DVD-ROM.)
Network difficulties
DifficultiesSuggestions
Cannot print over a wired Network. If you are having Network problems see the Network Users Guide on the 
CD/DVD-ROM for more information.
Make sure your machine is powered on and is on-line and in the Ready mode. 
Print the Network Configuration list to see your current Network settings. (See 
How to print a report on page 71.) Reconnect the LAN cable to the hub to verify 
that the cable and network connections are good. If possible, try connecting the 
machine to a different port on your hub using a different cable. If the connections 
are good, the lower LED of the back panel of the machine will be green.
