• Description: Stapler malfunction M105 Stapler mobility motor
• 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 by using the finisher component test from the controlpanel display. • 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 J5 and J6 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).

• Description: Stapler Stacker motor error Finisher upper-stapler motor failure (M41) Error occurs either when the stapler does not leave stapler home position (PI120) after staple motor (M41) is driven for 0.4 seconds or when it does not return to stapler home position after the staple motor has detected a motor-lock condition and the motor is driven backwards for 0.4 seconds, attempting to reach home position. NOTE: PI120 and M41 are located on the stapler assembly and can only be replaced by replacing the entire stapler assembly. M41 (Staple Motor) drives the insertion and crimping of the staple only (not the location of the staple on the paper). PI120 senses the home position of the stapler as it is inserting and crimping a staple only (not the location of the staple on the paper). The stapler-safety switch (MS103) assures that the stapler motor (M41) is disabled when it senses a finger might be in the stapler.
• Remedy: Control panel diagnostics: M41 Staple Motor (Staple-Shift Motor) and PI120 Stapler Home Sensor (Stapler Home Position Sensor). 1. Test the upper stapler-shift motor M41 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.

• Code: 66.80.38
• Display: 66.80.38
• Description: Stacker Stapler Mechanism Failed Occurs when stapler-alignment-interference sensor (PI116) is activated, signaling that the stapler unit is not in its proper position for stapling to occur. This is to prevent damage to stapler from occurring when stapler is positioned over one of the three stoppers when the signal to staple has been sent.
• Remedy: 1. If the stapler unite does not move correctly or moves erratically, check the flat-flexible cable (FFC) for damage (dents, folds, and/or tears). Replace the FFC if necessary. 2. If the stacker controller PCA was recently replaced, adjust the staple alignment and staple position. 3. If the stapler is not positioned over a stopper when this error occurs, perform the following steps: a. Make sure that the stapler unit is correctly mounted and securely fastened to the base. b. Make sure that the sensor is not obstructed or damaged. Make sure that the sensor flag is not damaged, moves freely, and is aligned correctly with the sensor body. c. If the error persists, replace the stapler subassembly. NOTE: The stapler subassembly includes the stapler unit and base.
