• Description: Stacker Staple Slide motor error Finisher upper stapler shift motor failure (M105). This error occurs when the stapler does not leave the stapler-shift home-position sensor (PI110) after the stapler-shift motor (M105) has driven for 5 seconds. This error also occurs when the stapler fails to return to the stapler-shift home-position sensor (PI110) after the stapler-shift motor (M105) has driven for 20 seconds.
• Remedy: Control panel diagnostics: M105 Staple Motor (Staple-Shift Motor) and PI110 Stapler Home Sensor (Stapler Home Position Sensor). 1. Test the upper stapler-shift motor M105 using the finisher component test from the product control panel. • If the stapler unit moves correctly, proceed to the next step. • If the stapler unit does not move correctly or moves erratically, perform the following steps: a. Check the flat-flexible cable (FFC) for damage (dents, folds, and/or tears). Replace the FFC if necessary. b. Check the FFC connectors and cable mounting areas. c. If the error persists, replace the stapler assembly. 2. Test the stapler-shift home-position sensor PI110 using the finisher component test from the product control panel. • If the sensor does not change state when the stapler unit is moved from the home position, perform the following steps: a. Make sure that the sensor is securely fastened to the chassis. b. Carefully clean the sensor body by gently blowing clean air across the sensor to remove dust band debris. c. Make sure that connector J6 and interconnect J1040 on the stacker controller PCA is fully seated and not damaged. Check the wiring at the sensor. d. If the error persists, replace the stapler assembly. NOTE: The stapler assembly includes the stapler-shift home position sensor PI110 stapler unit, shift-position-plate assembly, and the flat-flexible cable (FFC).
