This document will explain the step-by-step procedure on how to install an A4 block in a 550-sheet tray. The block's purpose is to keep the tray's rear guide fixed in A4 size and thus prevent it from be adjusted for longer media sizes. This is helpful in preventing possible rear-guide breakage due to repeated high impact insertions of the tray.
IMPORTANT! This block is only intended for 550 trays having the 40G3101 serial number. To verify this, empty the tray of media and flip it over to check the mark on the tray's underside. See image below.
