Duplex option sub error codes
Status byte 4 contains the most valuable information to help isolate a failing part or assembly in the
duplex option and is the only byte contained in the following table.
925 Service - Fuser Error (Wrong Fuser Lamp Installed)
Note: The following sub error codes are only for an incorrect lamp being installed.
EN 07 xx yy zz 1
EN -- -- -- 2
This error code is generated anytime an incorrect lamp is detected.
xx = 00 Lamp detection performed and found an error.
01 It took long to do lamp detection and NVRAM detected a previous wrong
lamp detected.
yy = Actual temperature
zz = The temperature that the fuser was trying to reach.
Status byte 4 Explanation
00 No duplex error. No problem was reported to the engine by the duplex system
card.
01 The leading edge of the sheet of paper never arrived at the input sensor.
02 The duplex option system board never received media notification from the
printer.
03 The trailing edge of the sheet of paper never cleared the input sensor.
04 The leading edge of the sheet of paper never arrived at the exit sensor.
Note: This error is the most common due to the long length of the paper path
between the input sensor and the exit sensor.
05 The duplex logic thinks a sheet of paper is feeding to the duplex option due to a
sensor malfunction in the paper path when in fact the printer has not sent a
command to send a sheet of paper to the duplex option.
06 The exit sensor detected a sheet of paper too early.
07 The sheet of paper trailing edge did not clear the exit sensor in the desired length
of time.
08 The feed motor experienced a complete motor stall.
0E The DC motor is under speed. The motor never reached the correct operating
speed.
13 There is paper left in the duplex option. Paper was sensed during the homing
operation during POST.
15 There is paper left in the duplex option. Paper was sensed during the DC motor
diagnostic test during POST.
18 The DC motor experienced an acceleration error.
3D There is paper left in the duplex option. Paper was sensed during IR clear during
POST.
