Tools Needed for Cleaning
Cleaning the waste ink absorber on a Canon i9900 requires precision and the right tools to avoid damage. The primary tool you’ll need is a set of latex or nitrile gloves to protect your hands from ink and cleaning solutions, which can stain skin and surfaces. Pair these with lint-free microfiber cloths to wipe down sensitive components without leaving residue. Avoid paper towels or tissues, as they can shed fibers and cause clogs.
Next, invest in a high-quality absorbent pad specifically designed for ink waste systems. Generic pads may not fit properly or absorb efficiently, leading to overflow. For deeper cleaning, a soft-bristle brush (like those used for electronics) helps remove dried ink from hard-to-reach areas. Ensure the bristles are non-conductive to prevent static discharge, which can harm the printer’s circuitry.
A distilled water and isopropyl alcohol solution (70% alcohol, 30% water) is essential for dissolving ink residue. Avoid tap water, as minerals can corrode printer parts. Apply this solution sparingly with a dropper or syringe to control the amount used, preventing liquid from seeping into electrical components. Always test the solution on a small area first to ensure compatibility.
Finally, a screwdriver set with Phillips and flathead options is necessary for accessing the waste ink absorber. Canon printers often require specific sizes, so verify compatibility before starting. Keep a container or tray nearby to catch any spilled ink during the process, minimizing mess and potential damage to your workspace.
By gathering these tools—gloves, microfiber cloths, absorbent pads, brushes, cleaning solutions, droppers, screwdrivers, and a tray—you’ll be well-prepared to tackle waste ink cleaning on your Canon i9900 efficiently and safely.

Step-by-Step Cleaning Process
The Canon i9900 printer’s waste ink absorber is a critical component that prevents ink overflow and maintains print quality. Over time, this absorber can become saturated, triggering error messages and halting operations. Cleaning the waste ink system is a precise process that requires careful attention to detail to avoid damage. Below is a step-by-step guide to effectively address this issue.
Step 1: Gather the Necessary Tools and Materials
Before beginning, ensure you have the following items: a waste ink reset tool (software or hardware), absorbent pads or paper towels, distilled water, cotton swabs, and protective gloves. For the Canon i9900, a software reset tool like the Canon Service Tool is often recommended. Avoid using tap water, as minerals can clog the printhead. If you’re uncomfortable with software resets, consider purchasing a replacement waste ink absorber kit, though this requires disassembling the printer.
Step 2: Access the Waste Ink Absorber
Power off the printer and unplug it from the power source. Locate the waste ink absorber, typically found beneath the printhead carriage. Gently move the carriage to the center for easier access. Use a screwdriver to remove the bottom panel or side covers, depending on your printer’s design. Be cautious not to damage internal components. Once exposed, inspect the absorber for saturation. If it’s overly wet, carefully remove it using tweezers or your gloved hands.
Step 3: Clean and Replace the Absorber
If the absorber is reusable, rinse it thoroughly with distilled water until the water runs clear. Squeeze out excess liquid and allow it to dry completely. Alternatively, replace it with a new absorber pad, ensuring it fits snugly in the designated area. For temporary solutions, place a folded paper towel or cotton pad in the absorber compartment to soak up excess ink. This is a stopgap measure and should be replaced with a proper absorber soon.
Step 4: Reset the Waste Ink Counter
After cleaning or replacing the absorber, reset the waste ink counter to clear error messages. Connect the printer to your computer and run the Canon Service Tool or similar software. Follow the on-screen instructions to locate and reset the counter. If using a hardware reset tool, connect it to the printer’s service port and follow the manual’s steps. Ensure the printer is powered on during this process. Once reset, power cycle the printer to confirm the error has been resolved.
Step 5: Test and Maintain
After reassembling the printer, perform a nozzle check and print test page to ensure proper functionality.

Preventing Future Waste Ink Buildup
Regular maintenance is key to preventing waste ink buildup in your Canon i9900 printer. Think of it like changing the oil in your car – neglect it, and you'll face costly repairs down the line. Canon recommends performing a nozzle check at least once a month, especially if you print infrequently. This simple test identifies clogged nozzles, allowing you to run a cleaning cycle before the problem worsens. Additionally, consider using the printer's "Deep Cleaning" function every 3-6 months, depending on usage. This more intensive cleaning process helps dislodge dried ink and prevent blockages in the waste ink pads.
Remember, preventative maintenance is far cheaper than dealing with a printer rendered unusable by overflowing waste ink.
The type of paper you use plays a surprising role in waste ink accumulation. Thicker, high-quality photo papers tend to absorb ink more efficiently, reducing the amount that ends up in the waste reservoir. Conversely, thin, low-quality papers can lead to excessive ink bleed-through, increasing waste. While premium paper might cost more upfront, it can save you money in the long run by extending the life of your waste ink pads and reducing the need for frequent cleanings.
Consider it an investment in both print quality and printer longevity.
Let's talk about printing habits. Large, solid color blocks or high-coverage photos generate significantly more waste ink than text documents or images with lighter coverage. If you frequently print such ink-heavy materials, be extra vigilant about maintenance. Schedule more frequent nozzle checks and cleanings to prevent buildup. Additionally, consider adjusting your printer settings to use "Draft" mode for less critical prints. This setting uses less ink, reducing waste and saving you money on ink cartridges.
Finally, don't overlook the importance of using genuine Canon ink cartridges. While third-party cartridges might seem like a budget-friendly option, they can sometimes contain inferior ink formulations that dry out faster or clog print heads more easily. This can lead to increased waste ink and potentially damage your printer. Genuine Canon ink is specifically designed for optimal performance and longevity in your i9900, minimizing waste and ensuring the best possible print quality. Think of it as using premium fuel for your high-performance printer.
