Metered Printing
Metered printing (PagePack), involves the combination of control software and 
specialized Toner Cartridges to meter printer activity for billing purposes. The 
Configuration page lists Metered Toner as Enabled when metering is enabled. 
Metered Operation
When a metered printer is initialized at first power-up, the customer sets the printer to 
Metered operation using a unique, factory-supplied, 4-digit PIN. Once set to Metered 
operation, the control software performs the following:
1. The Mode and PIN-entered values in Engine Control Board NVRAM are set.
2. The Control Panel momentarily displays “Metered Toner is now enabled”, then 
returns to “Ready” (if no other errors).
3. The First Time Tips pages and the Configuration page are printed.
If an incorrect PIN is entered, “Incorrect numeric password” displays with a prompt 
“Retry” or “Do not retry.” Retry returns to the enter prompt, “Do not retry” returns to 
the Replace [C][M][Y][K] Toner Cartridge error message. The error persists until the 
correct PIN is entered. 
Note
The Hidden Service menu provides an Enable Metered Toner option to restore 
the Metered mode parameters to NVRAM should they become lost or corrupt.
Metered Toner Cartridges
To support metered printing, metered Toner Cartridges are available in all four colors. 
When a metered Toner Cartridge is installed in a printer not set to Metered operation, 
the printer displays the “Replace [C][M][Y][K] Toner Cartridge” error. If a metered 
Toner Cartridge is placed into a printer manufactured before metering was available, 
the printer displays “Replace Incorrect Toner Cartridge.” All other combinations of 
normal or metered printer and cartridges are accepted without warning or error.
Diagnostics Mode
Service Diagnostics does not provide the utilities to set or clear Metered NVRAM 
values. Service Diagnostics does not check these values and does not display the 
current status of these values. However, the Configuration page does identify the 
printer setting as mentioned above.
Note
When replacing the Engine Control Board from a metered printer, exchange 
NVRAM devices or use the Save/Restore utilities in Service Diagnostics to 
preserve the NVRAM settings. The Mode and PIN-entered values are not 
affected by NVRAM reset utilities.
