1-4 Phaser 7400 Color Printer Service Manual

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.
