E5B5-xx16 due to sliding failure of the waste stopper in the wastepaper case assembly(Perfect Binder-B1,Perfect Binder-D1 )[Symptom]E5B5-xx16 error may occur during bookbinding operation.- E5B5-xx16 error: Waste detection error of Perfect binder[Cause]Waste paper [1], generated upon trimming, normally falls into the waste paper buffer [2]. In some cases, the waste paper [1] maygo into the space [4] between the waste paper buffer and the waste stopper [3]. If the waste paper goes in the space, the frictionalresistance increases at the front of the waste stopper. This prevents proper operation, resulting in the symptom.Figure [A] below shows paper waste that has properly fallen. Figure [B] shows the state in which waste paper has gone into thespace between the waste paper buffer and the waste stopper.[Service work]When the above mentioned symptom has occurred, prepare and replace with the Dust Stopper Unit (FM1-D248-000) followingthe procedure below. The procedure below starts from the step after disconnected Perfect binder from the copier main body.1) Checking sliding failure of the Waste stopper1-1) Open the front cover (Right/Left).1-2) While holding the front cover (Left), remove the upper/lower hinges to remove the front cover (Left). Pull the hinge in thedirection of arrow while pushing the black lever to remove the hinge.142
