The Magnet Bush Set for 12A (Left/Right Side) (Pack of 5 Pairs) is a replacement set of magnet bushes designed for the HP 12A toner cartridge (model Q2612A), which is commonly used in HP LaserJet printers, such as the HP LaserJet 1010, 1020, 3015, and similar models. These magnet bushes help with the proper functioning of the toner cartridge by ensuring smooth movement and proper toner transfer during the printing process.

Purpose of the Magnet Bushes in the HP 12A Cartridge:

• Alignment: The magnet bushes play a role in aligning the toner cartridge inside the printer, ensuring that it stays in place during the printing process.
• Toner Transfer: They help in the proper distribution of toner to the drum unit and ensure it is transferred effectively to the paper.
• Preventing Toner Leaks: The bushes also prevent potential toner spills or misfeeds, which can result in poor print quality or printer malfunctions.

Features of the Magnet Bush Set for HP 12A:

• Left and Right Side: The set contains a pair of bushes for the left side and another pair for the right side of the toner cartridge.
• Pack of 5 Pairs: A pack containing 5 pairs of magnet bushes is ideal for bulk replacement or for servicing multiple cartridges.

When to Replace the Magnet Bushes:

If the magnet bushes in your HP 12A cartridge are damaged or worn, you may encounter issues such as:

• Poor Print Quality: If the toner is not being transferred properly or evenly to the drum, printouts may appear faded or streaked.
• Paper Jams or Misfeeds: A malfunctioning or misaligned toner cartridge can cause paper jams or multiple sheets to be pulled through at once.
• Toner Leaks: If the magnet bushes are worn, the toner cartridge might leak toner or not dispense it correctly, causing print defects.
• Error Messages: The printer might display error messages related to a cartridge issue or alignment problem.
