Hello Boeing Portland Supp,
I searched the knowledgebase and found these tips for the 8-500 error code. If this doesn't help, you may need to contact your Support Department.
I have two Phaser 4622's and one 4600 that are all sharing the same issue. When attempting to print when the printer is in Sleep Mode the printer will get a paper jam in the fuser area with a 8 - 500 error. I have replaced the Fuser Assembly, Rear Door Assembly, Exit Assembly (MEA Unit -EXIT), and the Fuser Release Drive Assembly, all to no avail. These are all the parts that appear to handle paper after is goes through the Fuser Assembly.
Has anyone else seen this issue? It only occurs when attempting to print to a printer in Sleep Mode. Once the paper jam is cleared the printer will happily go on printing forever.
