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.
REPLACING THE IMAGE DRUM.
1.Press the cover release and open the printer’s top cover fully.
2. Holding it by its top centre, remove the us ed image drum and toner cartridge, out of 
the printer.
WARNING
> Never expose a image drum to an  open flame. It can cause an 
explosion and you can be burned.
> Be sure to switch off and unplu g the machine before accessing 
the interior of a machine for  cleaning, maintenance or fault 
clearance. Access to a live machin e’s interior can cause electric 
shock.
NOTE
> It is recommended that you change the toner cartridge and clean the LED 
array at the same time as you change the image drum.
> The B430dn model has been illustrated be low. The principles are the same 
for all the models of this printer.

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 selected 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.
