SERVICE PROGRAM MODE
[C]: Controller ROM version
The printer control board firmware version. The controller firmware consists of PCL
firmware, PostScript firmware and diagnostic firmware. The controller ROM version
changes when one or more of these is updated.
The controller firmware version is stored in the NVRAM on the printer control
board. Only the controller firmware can be installed by the IC card, DIMM card and
downloading from PC. The engine firmware and NIB firmware cannot be installed
using these methods.
[D]: Network ROM version
The NIB firmware version. The firmware can be updated with utility software on a
PC connected to the NIB through the network.
[E]: Sub Scan/Main Scan
Registration has been adjusted in the factory. The settings are stored in the
EEPROM on the ECB. When the EEPROM is cleared with service program mode
or is replaced in the field, the settings go to the defaults. Before clearing or
replacing the EEPROM, note the current values, then re-input them afterwards.
[F]: Tray paper status
This shows the paper size and amount of paper remaining. The remaining paper is
st nd rd
showed in 2 steps (for the 1 tray) or 4 steps (for the 2 and 3 trays). "0/4" means
no paper and "4/4" means the tray is full.
[G]: Transition/Density
This shows the transfer current and image density settings in the engine board.
These are user settings, and they go to normal when the EEPROM is cleared.
[H]: Counters
These counters can be reset using counter clear in the service program mode
menu, except for the motor work time. All counters are cleared when the EEPROM
is cleared.
The motor work time, paper feed roller counter, transfer roller counter, and fusing
unit counter are counted by the main motor rotation. The counters go up by one
every 5,000 seconds of motor working time.
These counters (except the motor work time) can be checked on the display using
the service program mode. To see the motor work time, look at "Maintenance
Counter" on the configuration page.
The paper feed roller counter, transfer roller counter and fuser counter are
automatically reset when new fusing unit in the Maintenance KIT is installed
(G031).
When the PM clear is performed by user menu, these counters are reset.
