CONSUMABLES AND MAINTENANCE
This section deals with the replacement of the toner cartridge and image drum and general 
maintenance.
CONSUMABLE ORDER DETAILS
Please always use genuine consumables. 
TONER CARTRIDGE LIFE
How long your toner cartridge lasts depends on  the print density; the percentage of the 
page that prints black. A typical letter has 3% to 5% print density; graphics usually have 
higher density. Higher print density means toner is used up faster. At 5% print density, a 
standard toner cartridge will print an averag e of 3500 pages. Remember, this is only an 
average:actual re sults may vary.
The first toner cartridge installed in a new pr inter has to fill the image drum reservoir and 
saturate the developing roller with toner. Th e toner cartridge that is supplied with this 
printer normally produces about 1,500  pages after installation.
WHEN TO REPLACE THE TONER CARTRIDGE
When the toner is running low, TONER LOW is  displayed in the operator panel LCD. After 
Toner Low displays, the printer will print ab out 100 more pages then display Toner Empty 
and stop printing. Printing will resume after a new toner cartridge has been installed.
REPLACING THE TONER CARTRIDGE
It is recommended that you clean the LED arra y at the same time as you change the toner 
cartridge.
The toner used in this printer is a very fine  dry powder contained in the toner cartridge.
Have a sheet of paper handy so that you have  somewhere to place the used cartridge while 
you install the new one.
Dispose of the old cartridge re sponsibly, inside the pack that the new one came in. Follow 
any regulations, recommendations, etc., which  may be in force concerning waste recycling.

IMAGE DRUM LIFE
The life of an image drum depends on a number of factors, including temperature and 
humidity, the type of paper used, and the number of pages per job.
The image drum should last approximately 25, 000 pages continuous printing. This number 
is approximate because different numbers of pages are printed each time and the 
environmental conditions and th e paper type used may vary.
WHEN TO REPLACE THE IMAGE DRUM
When the drum reaches 90% of its life, a  CHANGE DRUM message is displayed in the operator 
panel LCD. Change the image drum when the pr int becomes faint or begins to deteriorate.

the interior of a machine for  cleaning, maintenance or fault 
clearance. Access to a live machin e’s interior can cause electric 
shock.

TROUBLESHOOTING
STATUS AND ERROR MESSAGES
Your printer has been designed to give you helpful status feedback not only during normal 
operation but also if a printing problem occurs  so that you can take appropriate corrective 
action.
The LCD on the printer operator panel provid es the self-explanatory status and error 
messages in your chosen language. Erro r messages are accompanied by the Ready 
indicator being extinguished.
PAPER JAMS
Provided that you follow the recommendations in  this guide on use of print media, and you 
keep the media in good condition prior to use,  your printer should give years of reliable 
service. However, paper jams occasionally do o ccur, and this section explains how to clear 
them quickly and simply.
Jams can occur due to paper misfeeding from  a paper tray or at any point on the paper 
path through the printer. When a jam occu rs, the printer immediately stops, and the 
operator panel informs you of the event. If  printing multiple pages (or copies), do not 
assume that having cleared an obvious shee t that others will not also be stopped 
somewhere along the path. These must also be  removed in order to clear the jam fully and 
restore normal operation.
The printer may experience a paper jam in one of three areas. 
1. INPUT JAM - paper has failed to leave the se lected feed tray and enter the internal 
paper path of the printer.  A typical message indicates a  paper jam and identifies the 
tray to check.
2. FEED JAM - paper has entered the printer  but failed to reach the exit. A typical 
message indicates a paper jam and advises you to open the top cover for access.
3. EXIT JAM - paper has reached the exit but  has failed to exit completely from the 
printer. A typical message indicates an ex it jam and advises you to open the top 
cover for access.
