Common causes

  • 1Dirty or dried ink-stained electrical contacts.
  • 2Use of non-original consumables with faulty chips.
  • 3Electrical arcing on printhead connectors.
  • 4Overvoltage on the charge management board.

Solutions

Diagnóstico rápido

The SC302 code appears when the printer detects abnormal voltage readings. If you have recently installed a new or non-original cartridge, this error is the system's reaction to potential electrical or chip irregularities.

Solución paso a paso

  1. Inspect Cartridges: Remove cartridges and verify that contact pins are not bent or dirty.
  2. Charging Reset: Power off and unplug for 20 minutes to clear residual charges.
  3. Cleaning: If you detect dried ink on contacts, wipe gently with a dry cloth. Do not use alcohol or water.
  4. Replacement: If the error persists, test with a brand new original cartridge to rule out a faulty chip.

Prevención y mantenimiento

Avoid touching the golden pins of cartridges with your fingers. Skin oils can increase electrical resistance. Always use original consumables to maintain internal circuitry integrity.

Cuándo llamar a un técnico

If replacing with original cartridges does not clear the SC302 error, the charging control board may have been permanently damaged.

Frequently asked questions

The SC302 is a charging voltage error. It indicates an electrical anomaly in the contacts between the cartridge and the print system.

No, the use of compatible cartridges is often the root cause of this error, as chip and contact quality are lower.

If the error persists, there is electrical risk to internal components; stop use and contact a professional.

Use a dry, lint-free cloth to clean pins if removing cartridges. Never use corrosive liquids.
