The printer suspends operation and waits for user confirmation when a
disk error is detected. When you confirm the disk error message, the
disk subsystem is disabled and the printer starts again without the disk
after you turn the power off and back on. When this occurs, any jobs in
progress or spooled are lost.
Note:Even if a disk error occurs, the copier function is available.
A flag is set in NVRAM to indicate that a disk error was detected.
When a power on occurs with this flag set, the printer operates without
disk services. You must perform a SYSTEM RESET to clear this flag.
Verify that the size and weight of the paper you are using meets the
paper specifications for the printer.
Verify whether the paper is folded, wrinkled, damp, or curled.
Verify that the paper is correctly placed in the paper tray.
Check for any pieces of misfed paper or other foreign objects in the
machine.
Verify that the page size setting is correct for the paper contained in the
feeder tray.
specifying Bypass feed is ready to print and the Bypass tray door is
closed. This message is followed by a "No paper. Add size paper to
Bypass Tray" message. These messages are repeated when the
Bypass tray runs out of paper.
When the bypass tray is not opened within a specific time period, the
job will be canceled automatically. The time period is called the bypass
tray time-out. You can set the manual time-out using the Control Panel
menus.
To avoid manually fed paper (such as transparencies) from jamming in
the duplexer or stapling stack, manual feed print jobs cannot be
duplexed or stapled.
