To print the Menu Settings Page:
1. Select the TESTS MENU.
2. Select Print Menus from the TESTS MENU.
The page contains the following information:
• A list of all the printer settings contained in the control panel
menus and their values.
• A list of the installed options and features such as RAM memory
SIMMs, optional input paper trays, envelope feeder, duplexer,
output bins, flash or disk.
• Printer information such as serial number, page count, installed
RAM, engine code level, RIP code level, envelope feeder code
level, tray 1-5 code levels, output bin 1-3 code levels, control
panel code levels, font ROM version and SRAM availability.
Autocompensator Operation
The autocompensator is a paper pick device that generates its own
normal force. This force generation is inherent in the fundamental
design of the pick arm. If light media is used, it picks very gently. If a
heavy media is used, it picks very aggressively. No customer
adjustments are necessary, therefore no special trays are needed for
card stock or labels.
The gearing in the arm is designed so the input torque from the
motor produces a movement about the pivot of the arm. This
movement produces a downward force at the pick rolls. The friction
between the pick roll and the paper produces a frictional locking
condition. If the paper is physically held and not allowed to feed, then
the motor stalls. Slippage between the roll and the paper is
theoretically impossible. When the motor is energized the pick rolls
are driven down into the stack increasing the normal force and drive
force until the bending strength of the paper is overcome and the
paper bends and moves up the dam. Once this critical threshold is
achieved the normal force remains at a level just high enough to
reliably feed the paper. Rather than having a fixed spring force for
