Xerox 3635MFP/S User Manual

Customer Replaceable Units (CRUs) are modules within the workings of the 
machine that you can replace when needed.  The machine monitors the 
number of copies made for service information purposes. This information 
helps maintain the machine’s productivity and image quality.  

When a module is nearing the end of its life, a message displays advising you 
to order a new module.  

When a module reaches the end of its life, a message displays advising you 
to replace the module.

To easily identify the Customer Replaceable Units the latches are colored 
orange.

Toner usage depends on the type and the number of images printed. The 
machine calculates how long the toner will last according to your usage of the 
machine and displays the information on the Machine Status - Service 
Information screen. It also uses this information to tell you when to order a new 
Print Cartridge and when to install it. This facility allows you to control how the 
toner usage monitoring system works.

Select the Supplies tab and select the Print Cartridge Reorder Notification 
button.

With the Print Cartridge Status Enabled, the machine will analyze the toner 
usage to predict the percentage of toner remaining and display the information 
on the Machine Status - Service Information screen. When the percentage of 
toner remaining equals the number set in the window on this screen, a 
message will be displayed telling you to order a new Print Cartridge. You can 
set the percentage level the message displays using the scroll buttons.

When the Print Cartridge Reorder Notification threshold is reached a message 
will be displayed. Once you have a new Print Cartridge you can turn the 
message off by selecting the Cancel Current Re-order Message(s) button. 
The machine will display a message when it is time to install the new Print 
Cartridge.

When the Print Cartridge Status is Disabled, the machine will not predict the 
toner usage and you will not receive a re-order reminder. The Machine Status 
- Service Information screen will say that the toner monitoring function is 
disabled. When the machine has run out of toner you will be told to replace the 
Print Cartridge.

If you replace the Print Cartridge when instructed to do so by the message on 
the display, the machine will assume that you have installed a new Print 
Cartridge and reset the toner usage counters. However, if you choose to install 
a new Print Cartridge before the message is displayed you will have to reset
