Laser Notice
The printer is certified in the U.S. to conform to the requirements of DHHS 21 CFR Subchapter J for Class I (1) laser products, and elsewhere is certified as a Class I laser product conforming to the requirements of IEC 825. Class I laser products are not considered to be hazardous. The printer contains internally a Class IIIb (3b) laser that is nominally a 5 milliwatt gallium arsenide laser operating in the wavelength region of 770-795 nanometers. The laser system and printer are designed so there is never any human access to laser radiation above a Class I level during normal operation, user maintenance, or prescribed service condition.

Status Bytes 1, 2,3 84 xx 00

Explanation The input sensor is still covered by the first sheet of paper through the printer and the second sheet is ready to arrive at the sensor. Video information has not started on the page at the input sensor within two inches after activating the input sensor flag. The media takes too long to complete a pass through the input sensor. This can occur when a sheet of paper is in the machine during POST and the input sensor flag has tripped the input sensor. This error is generated whenever media is seen at the input sensor before the sensor flag activates the input sensor. A paper jam is detected by the tray you are trying to feed from. A paper jam is detected by a smart option and an error message displays. Paper Tray 5 pass thru sensor is not activated by a sheet of paper. Paper Tray 4 pass thru sensor is not activated by a sheet of paper. Paper Tray 3 pass thru sensor is not activated by a sheet of paper. Paper Tray 2 pass thru sensor is not activated by a sheet of paper. Paper Tray 5 pass thru sensor is not activated and never deactivated.

Explanation There was no envelope feeder error reported. Printer failed POST - Homing of Envelope feeder Printer failed POST - Halted Envelope Feeder The envelope feeder failed to feed, envelope jam. The D.C. motor failed to reach operating speed. The motor stalled. The motor failed to stop.

Duplex Unit 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.
Status Byte 4 00 01 02 03

Explanation No duplex error. No problem was reported to the engine by the duplex system card. The leading edge of the sheet of paper never arrived at the input sensor. The duplex option system board never received media notification from the printer. The trailing edge of the sheet of paper never cleared the input sensor.

Diagnostic Information 2-10

4059-XXX
Status Byte 4 04 Explanation 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. The duplex logic thinks a sheet of paper is feeding to the duplex unit 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 unit. The exit sensor detected a sheet of paper too early. The sheet of paper's trailing edge did not clear the exit sensor in the desired length of time. The feed motor experienced a complete motor stall. The D.C. motor is under speed. The motor never reached the correct operating speed. There is paper left in the duplex option. Paper was sensed during the homing operation during POST. There is paper left in the duplex option. Paper was sensed during the DC motor diagnostic test during POST. The D.C. motor experienced an acceleration error. There is paper left in the duplex option. Paper was sensed during IR clear during POST.

User Error Message 31 Defective Print Cartridge Explanation Error code 31 is displayed when the top front cover is closed and a defective print cartridge is detected. It may take the printer 10-20 seconds to determine if the print cartridge is defective. Depending on the setting of the Machine Class ID the printer may be allowed to print pages during this 10-20 second interval. If pages are allowed to print, they are not reprinted once a good print cartridge is inserted. Note: This error indicates the printer was able to read the cartridge ID, but the ID did not pass the verification test. To pass the verification test, the ID read from the print cartridge must match the ID from the last "good" print cartridge or the same ID must be read from the print cartridge twice. The last "good" print cartridge ID is stored in NVRAM. 32 Unsupported Print Cartridge Error 32 is displayed when the top cover is closed and an unsupported print cartridge is detected. It may take the printer 10-20 seconds to determine if the print cartridge is supported. Depending on the setting of the Machine Class ID the printer may be allowed to print pages during this 10-20 second interval. If pages are allowed to print, then they are not reprinted once a good print cartridge is inserted. This error message also displays on a model 3455 printer if the smart cartridge or smart cartridge hardware is not operating correctly. Try another model 3455 print cartridge. If this does not fix the problem, go to "Smart Cartridge Service Check" on page 2-102. The printer determines the paper length is too short to print the formatted data. This occurs when the printer does not know the actual paper size loaded in the tray. For auto-size sensing trays, this error occurs if the paper stop is in the incorrect position. Make sure the Paper Size setting is correct for the size paper that is being used.
