Jam Codes Jam codes are stored in the printer's Jam History each time paper jams occur. Each Phaser 8400 jam code contains a group of three digits while Phaser 8500 and 8550 jam codes contain four digits. The jam codes identify the information indicated below. ■ Print process that was active when the jam occurred ■ The reason or basis for reporting the jam ■ Page count when the jam occurred ■ Tray from which jammed paper was picked (1 - 4) or when processing chase or duplex pages (Phaser 8500 and 8550 only) ■ Printer state when the jam occurred Phaser 8400 2 0 : A 2 C : 7 7 3 Jam Code Print Process Event Page Count Reason for Jam Printer State Phaser 8500/8550 Jam Code 20:F2N2:773 Page Count Print Process Event Tray/Chase/Duplex Reason for Jam Printer State Tables located in the Jam Codes section of the Service Manual define the jam code digits and provide troubleshooting procedures for specific codes.

Print Engine Fault Codes Print engine faults can occur during the power-on sequence or during printer operation. Many faults can be cleared by cycling the printer's power switch. When a fault occurs, the printer automatically resets in an attempt to clear the error. The printer reboots, beginning with the BIST and POST tests, and attempts to complete the power-on sequence. If the fault persists after the automatic reboot sequence, the print engine fault code appears on the display. This code is stored in the printer's Engine Error History and is included on the embedded Printer Status Page and Usage Profile Report. Each print engine fault code contains four fields as shown to the right. The fields define the failing printer system, subsystem, problem type, and page count when the error occurred. The Service Manual's Fault Code Error Message Troubleshooting section provides troubleshooting procedures for each code. 7,009.42:836 Failing System Failing Subsystem Page Count Type of Problem page 70 PHASER 8550, 8500, & 8400 SERVICE SECTION Version 1.0
