Printer Hardware Repair
When a printer grinds, stalls, shows a fault light or simply refuses to start, the cause is usually physical: a worn roller, a stuck carriage, a failed sensor or a tired power supply. We find the part that is actually failing before anything is replaced.
Common symptoms
- Grinding, clicking or knocking noises during printing
- Printer will not power on, or switches itself off
- Carriage stops part-way or the printer reports a carriage jam with no paper inside
- Paper is picked up crooked, creased or not at all
What it covers
- Diagnosis of mechanical and electrical faults
- Roller, gear and paper-path work
- Carriage, encoder and sensor issues
- Testing with real print jobs before we finish
