Canon FC7-3644-000 paper delivery sensor flag is a replacement component identified in Canon’s parts catalog for the fixing assembly. Its purpose is to serve as the flag for the paper delivery sensor, making it a specific part of the printer’s paper handling mechanism.
The catalog lists one flag per assembly and distinguishes it from the separate paper width sensor flag. This helps identify FC7-3644-000 by its paper delivery sensing role rather than by a similar nearby part number. The part is suited to service or repair work where this exact sensor flag is required.
