The scanner axis motor, responsible for moving the scanning carriage, is not functioning correctly or is obstructed. This prevents the MFP from performing any scanning or copying operations.
- 1
Turn the printer off and then on again.
- 2
Open the scanner lid and carefully inspect the scan axis area for any obstructions, such as paper scraps, staples, or foreign objects.
- 3
Gently try to move the scanner carriage by hand (when the printer is off) to check for resistance. Do not force it.

Model-Specific Notes: • T-Series MFP (e.g., T1700dr, T850/T950 MFP): Pay close attention to the scanner's flat ribbon cables and their connection to the formatter board. These can become loose or damaged. Expert Insight: After removing any visible obstructions, check the scanner's encoder strip for dirt, damage, or misalignment. Clean it gently with a lint-free cloth and isopropyl alcohol. Use a multimeter to check continuity on the motor's power supply if you suspect an electrical issue, but this typically requires disassembling the scanner unit.
