Suggestions
You can load envelopes from the manual feed slot. 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.)
You can use plain paper, recycled paper, transparency and labels that are made
for laser machines. (For details, see Acceptable paper and other print media
on page 14.)
(See Paper jams on page 114.)
Suggestions
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 14.)
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 14 and Basic tab in the Software User's
Guide on the CD-ROM.)
If this problem occurs when making copies or printing received faxes, turn
Toner Save mode to off in the machine menu settings. (See Toner save
on page 22.)
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-ROM.)
Suggestions
ROM for more information.
Make sure your machine is powered on and is on-line and in the Ready state.
Print the Network Configuration list to see your current Network settings. (See
How to print a report on page 67.) 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.
