Definitely check the LSU glass but if they are far from your office then bring a Primary Transfer belt. I have had the BK roller under the belt pop out of its rear holder. Also check the right side door and make sure its closed properly, it is notorious for uneven latching. One more item to double check is the paper guide below the TX belt, its the one you must release and push downwards to remove the belt. I have seen it left in the down position by techs and on accident by the customer, make sure you hear it click in place properly. Might want to bring a fuser with you too since its so far, they fail sometimes and can leave the machine down but this is unrelated to your question. Good luck.

Read Woxner's post. With all due respect, credit should be given him.

It cost you an image unit & toner when should have been a 5 min free fix & no downtime for your customer a lesson learnt.
