For Xerox B310, B305, and B315 models, replacing the original toner chip with a compatible one like the 006R04379, 006R04376, 006R04377, 006R04378, 006R04380, or 006R04381 series ensures continued operation after refilling or using third-party toner cartridges. <dl> <dt style="font-weight:bold;"> <strong> MC Printer </strong> </dt> <dd> Refers to a category of multifunctional laser printers, often used in small to medium-sized offices, that support various printing, scanning, and copying functions. The term MC is commonly used in the context of Xerox’s product line, particularly models like the B310, B305, and B315. </dd> <dt style="font-weight:bold;"> <strong> Toner Chip </strong> </dt> <dd> A microchip embedded in a toner cartridge that stores data such as toner level, cartridge ID, and usage history. It communicates with the printer to prevent unauthorized or empty cartridges from being used. </dd> <dt style="font-weight:bold;"> <strong> Cartridge Chip </strong> </dt> <dd> A generic term for the electronic component in a toner or ink cartridge that enables the printer to recognize and authenticate the cartridge. </dd> </dl> I’ve been using a Xerox B310 in my home office for over two years. After the third refill of my original toner cartridge, the printer started displaying “Toner Low” even though the cartridge was full. I tried resetting the printer, but the error persisted. I discovered that the toner chip had failed during the refill process. Without a working chip, the printer wouldn’t accept the cartridge, even if it was properly filled. I researched compatible replacement chips and found the 006R04379, 006R04376, 006R04377, 006R04378, 006R04380, and 006R04381 series. These are designed specifically for Xerox B310, B305, and B315 models. I purchased a pack of five chips, each labeled with the correct part number, and installed one on my refilled cartridge. Here’s how I confirmed compatibility and functionality: <ol> <li> Identify the exact model of your printer: Xerox B310, B305, or B315. </li> <li> Locate the original toner chip on the cartridge. It’s a small rectangular component near the top, often with a silver contact pad. </li> <li> Match the chip’s part number to the correct model. The 006R04379 series is compatible with all three models. </li> <li> Remove the old chip carefully using a small flathead screwdriver or chip removal tool. </li> <li> Attach the new chip by aligning the contacts and pressing it firmly into place. </li> <li> Insert the cartridge into the printer and power it on. </li> <li> Check the printer’s control panel for any error messages. If the message disappears and printing starts, the chip is working. </li> </ol> Below is a comparison of the key specifications between the original and replacement chips: <style> .table-container width: 100%; overflow-x: auto; -webkit-overflow-scrolling: touch; margin: 16px 0; .spec-table border-collapse: collapse; width: 100%; min-width: 400px; margin: 0; .spec-table th, .spec-table td border: 1px solid #ccc; padding: 12px 10px; text-align: left; -webkit-text-size-adjust: 100%; text-size-adjust: 100%; .spec-table th background-color: #f9f9f9; font-weight: bold; white-space: nowrap; @media (max-width: 768px) .spec-table th, .spec-table td font-size: 15px; line-height: 1.4; padding: 14px 12px; </style> <div class="table-container"> <table class="spec-table"> <thead> <tr> <th> Feature </th> <th> Original Xerox Chip (006R04379) </th> <th> Replacement Chip (006R04379/006R04376/006R04377/006R04378/006R04380/006R04381) </th> </tr> </thead> <tbody> <tr> <td> Compatibility </td> <td> Xerox B310, B305, B315 </td> <td> Xerox B310, B305, B315 </td> </tr> <tr> <td> Chip Type </td> <td> Reprogrammable EEPROM </td> <td> Reprogrammable EEPROM </td> </tr> <tr> <td> Memory Capacity </td> <td> 2KB </td> <td> 2KB </td> </tr> <tr> <td> Operating Voltage </td> <td> 3.3V </td> <td> 3.3V </td> </tr> <tr> <td> Connection Interface </td> <td> Standard 6-pin contact </td> <td> Standard 6-pin contact </td> </tr> <tr> <td> Price per Unit (USD) </td> <td> $12–$15 </td> <td> $2.50–$3.50 </td> </tr> </tbody> </table> </div> The replacement chip not only restored functionality but also saved me over $10 per cartridge.

The process takes less than 5 minutes and preserves the cartridge’s integrity. I’ve installed over 12 replacement chips on my refilled toner cartridges for the Xerox B310. Each time, I followed a consistent method that minimized risk of damage. The key is to avoid applying excessive force and to ensure the chip is seated properly. Here’s my step-by-step process: <ol> <li> Power off the printer and remove the toner cartridge from the machine. </li> <li> Place the cartridge on a clean, flat surface with the chip side facing up. </li> <li> Use a small flathead screwdriver or a dedicated chip removal tool to gently pry the old chip from its socket. Apply pressure only at the edgesnever on the chip’s circuitry. </li> <li> Inspect the socket for debris or bent pins. Clean with a dry cotton swab if needed. </li> <li> Take the new replacement chip (e.g, 006R04379) and align it with the socket. The chip has a notch on one end that matches the socket’s keying. </li> <li> Press the chip down evenly with your thumb until it clicks into place. Do not twist or force it. </li> <li> Double-check that all contacts are fully seated and that the chip is flush with the cartridge surface. </li> <li> Reinsert the cartridge into the printer and power it on. </li> <li> Print a test page. If the printer recognizes the cartridge and prints normally, the installation was successful. </li> </ol> I’ve never damaged a cartridge using this method. The chip is designed to be removable and replaceable without affecting the toner reservoir or drum unit. One common mistake is using too much force when removing the old chip. I once tried to pull it out with pliers and bent a contact pin. That cartridge had to be discarded. Since then, I’ve used only a plastic spudger and a flathead screwdriver. Another tip: Always handle the chip by the edges. Avoid touching the metal contacts with your fingers, as oils from skin can interfere with electrical connections. The replacement chips I use are made with high-quality materials and are designed to withstand repeated installation and removal. They’re also tested for compatibility with Xerox B310, B305, and B315 firmware versions. <h2> Can I Use the Same Toner Chip Across Multiple Cartridges for My Xerox B310? </h2> <a href="https://www.aliexpress.com/item/1005008990050677.html" style="text-decoration: none; color: inherit;"> <img src="https://ae-pic-a1.aliexpress-media.com/kf/S48f807ea7a0d4e6cb00f62dea499fcday.jpg" alt="3K 8K 20K B310 006R04379 006R04376 006R04377 006R04378 006R04380 006R04381 Toner Chip for Xerox B310 B305 B315 Drum Chip" style="display: block; margin: 0 auto;"> <p style="text-align: center; margin-top: 8px; font-size: 14px; color: #666;"> Click the image to view the product </p> </a> <strong> Answer: </strong> No, each toner chip is designed to be used with a single cartridge and is programmed to recognize a specific cartridge ID. Reusing a chip across multiple cartridges will cause the printer to reject the cartridge, display an error, or fail to initialize. I learned this the hard way. After refilling three cartridges for my Xerox B310, I thought I could save money by reusing the same chip on all of them. I removed the chip from the first cartridge, installed it on the second, and powered on the printer. The screen flashed “Invalid Cartridge” and refused to print. I checked the chip’s part number006R04379and confirmed it was compatible with the B310. But the printer still rejected it. I realized that the chip had been programmed with a unique ID tied to the first cartridge’s serial number. I consulted the manufacturer’s documentation and found that these chips are not reusable. Each chip is factory-programmed with a unique identifier that the printer verifies during initialization. Even if the chip is physically identical, the printer will not accept it if the ID doesn’t match. To fix the issue, I purchased a new chip for each cartridge. I now keep a spare set of six chips (006R04376, 006R04377, 006R04378, 006R04379, 006R04380, 006R04381) in a labeled container. I assign one chip per cartridge and never reuse them. This approach ensures reliability and avoids downtime. I’ve had zero errors since switching to this system. <h2> Why Does My Xerox B310 Still Show “Toner Low” After Installing a New Toner Chip? </h2> <a href="https://www.aliexpress.com/item/1005008990050677.html" style="text-decoration: none; color: inherit;"> <img src="https://ae-pic-a1.aliexpress-media.com/kf/Sb2b6ed654d09452b8ac9b14e14d4ddb2L.jpg" alt="3K 8K 20K B310 006R04379 006R04376 006R04377 006R04378 006R04380 006R04381 Toner Chip for Xerox B310 B305 B315 Drum Chip" style="display: block; margin: 0 auto;"> <p style="text-align: center; margin-top: 8px; font-size: 14px; color: #666;"> Click the image to view the product </p> </a> <strong> Answer: </strong> The “Toner Low” error persists after installing a new toner chip if the chip is not properly reset or if the printer’s internal toner level counter hasn’t been cleared. Resetting the chip and clearing the printer’s memory resolves the issue in 95% of cases. I encountered this exact problem after installing a new 006R04379 chip on a refilled cartridge. The printer recognized the cartridge, but the display showed “Toner Low” and wouldn’t print. I checked the toner level with a toner level checker appthere was still 80% toner left. I suspected the chip wasn’t properly reset. I researched the reset procedure and found that the 006R04379 chip requires a manual reset after installation. Here’s how I fixed it: <ol> <li> Power off the printer and remove the cartridge. </li> <li> Locate the reset button on the chip (a small recessed button on the side. </li> <li> Use a paperclip or small pin to press and hold the reset button for 5 seconds. </li> <li> Release the button and reinsert the cartridge. </li> <li> Power on the printer and wait for it to initialize. </li> <li> Check the control panel. The “Toner Low” message should disappear. </li> <li> Print a test page to confirm functionality. </li> </ol> After following these steps, the error disappeared immediately. The printer now shows “Toner Full” and prints normally. Some users report that the reset button is not always accessible. In such cases, you can use a chip programmer to reprogram the chip’s memory. However, this requires additional tools and technical knowledge. For most users, the manual reset method is sufficient and reliable. <h2> How Do I Choose the Right Toner Chip for My Xerox B310 Among the 006R04379, 006R04376, 006R04377, 006R04378, 006R04380, and 006R04381 Series? </h2> <a href="https://www.aliexpress.com/item/1005008990050677.html" style="text-decoration: none; color: inherit;"> <img src="https://ae-pic-a1.aliexpress-media.com/kf/S73d9b02604434825a8de0c76366429626.jpg" alt="3K 8K 20K B310 006R04379 006R04376 006R04377 006R04378 006R04380 006R04381 Toner Chip for Xerox B310 B305 B315 Drum Chip" style="display: block; margin: 0 auto;"> <p style="text-align: center; margin-top: 8px; font-size: 14px; color: #666;"> Click the image to view the product </p> </a> <strong> Answer: </strong> All chips in the 006R04379, 006R04376, 006R04377, 006R04378, 006R04380, and 006R04381 series are functionally identical and fully compatible with Xerox B310, B305, and B315 models. The different part numbers are used by manufacturers for internal tracking and batch management, not for functional differences. I’ve used all six variants across multiple cartridges.
